The butterfly effect is a phrase that encapsulates the more technical notion of sensitive dependence on initial conditions in chaos theory. Small variations of the initial condition of a dynamical system may produce large variations in the long term behavior of the system. This is sometimes presented as esoteric behavior, but can be exhibited by very simple systems: for example, a ball placed at the crest of a hill might roll into any of several valleys depending on slight differences in initial position.
It is a common subject in fiction when presenting scenarios involving time travel and with "what if" scenarios where one storyline diverges at the moment of a seemingly minor event resulting in two significantly different outcomes.
//////////////////CONTINENTAL DRIFT=The most famous early proponent of continental drift, German geophysicist Alfred Wegener, was received skeptically when he proposed his theory in 1912, partly because he couldn't explain what might cause giant landmasses to move around. Expanding-earth advocates thought they could. They posited that once upon a time the earth had been much smaller and was completely encased in the supercontinent we now call Pangaea. Volcanic activity caused the planet to expand, cracking Pangaea apart like the shell of a boiled egg and leading to the eventual scattering of the continents.
Obvious objection: Where was all the extra volume that went into the expanding earth supposed to be coming from?

From Chapter I: The Yoga of Arjuna's Despondancy
I.26. Then, Arjuna (son of Pritha) saw there (in the armies)
stationed, fathers and grandfathers, teachers, maternal uncles,
brothers, sons, grandsons, and friends too.
I.27. (Arjuna saw) fathers-in-law and friends also in both the
armies. The son of Kunti, Arjuna, seeing all those kinsmen thus
standing arryed, spoke this, sorrowfully filled with deep pity.
//////////////////////Long-Lost Cousins
In contrast to chimpanzees, who live in male-dominated societies with infanticidal tendencies and other forms of lethal aggression, bonobos live in societies that are highly tolerant and peaceful thanks to female dominance, which maintains group cohesion and regulates tensions through sexual behavior.
//////////////////// Bonobos are notorious for their sexuality. Females rub their clitorises together; males have sexual activity with males. Neither age nor gender seems to matter. Sex is a tension-relieving activity in the group, used to soothe ruffled tempers or form alliances. It also appears to be a negotiating activity, engendering a high level of tolerance in bonobos.
So what we have are chimps who cooperate but aren't very tolerant, and bonobos who are very tolerant but don't really cooperate in the wild. What probably happened six million years ago, when hominids split from the ancestor we share with chimpanzees and bonobos, is that we became very tolerant, and this allowed us to cooperate in entirely new ways. Without this heightened tolerance, we would not be the species we are today.

Reduced omega-3 and elevated trans-fatty acid levels predict nonfatal heart attack better than established risk factors
An article published online on June 9, 2009 in the British Journal of Nutrition reported the conclusion of a study conducted by South Korean researchers that red blood cell fatty acid profiles may prove to be a better predictor of who is at risk of heart disease than Framingham risk factors.
Framingham risk scores are calculated from values for the following traditional risk factors: age, gender, smoking status, total cholesterol levels, HDL-cholesterol levels, diabetes history and hypertension history. While an individual’s Framingham score is 70 to 80 percent accurate in predicting coronary heart disease risk, it fails to take into account more recently recognized risk factors that could improve its predictive value.
The researchers, from the Hanyang University in Seoul, matched 50 men and women with acute nonfatal myocardial infarction (heart attack) with 50 age and gender-matched controls who did not have a history of heart attack. Red blood cells were analyzed for levels of trans-fatty acids (undesirable fatty acids found in partially hydrogenated vegetable oil), and the beneficial omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) (found in fish and the algae they feed on).

//////////////////..........ABT COM=Clinical Depression Vs. Sadness
Monday July 20, 2009
Q. What is the difference between clinical depression and sadness?
A. Although depression is often thought of a being an extreme state of sadness, there is a vast difference between clinical depression and sadness. Sadness is a part of being human, a natural reaction to painful circumstances. All of us will experience sadness at some point in our lives. Depression, however, is a physical illness with many more symptoms than an unhappy mood. The person with clinical depression finds that there is not always a logical reason for his dark feelings. Exhortations from well-meaning friends and family for him to "snap out of it" provide only frustration for he can no more "snap out of it" than the diabetic can will his pancreas to produce more insulin. Sadness is a transient feeling that passes as a person comes to term with his troubles. Depression can linger for weeks, months or even years. The sad person feels bad, but continues to cope with living. A person with clinical depression may feel overwhelmed and hopeless.
/////////////////Diabetic Diet: The Basics
Be consistent. Eat about the same amount of food each day around the same times of day, and don't skip meals or regular snacks.
Watch the type of calories you eat. Between 40 percent to 60 percent of the calories in a healthy diet will come from carbohydrates. Around 20 percent of calories should come from protein and 30 percent or less from fat.
Consume carbohydrates high in fiber. They digest slowly and keep blood sugar levels stable. Pick foods made with whole grains rather than products containing processed grains. Brown rice, dried beans, whole wheat spaghetti, and lentils are good choices.
Eat plenty of vegetables and fruits. In general, eat more non-starchy vegetables, and reduce your portions of everything else. Non-starchy vegetables like broccoli, spinach, carrots, or green beans are best. Remember that whole fruits and vegetables are more nutritious than juices or dried fruit.
Eat foods low in saturated fat and free of trans-fats. Choose lean meats. Cuts of beef and pork that end in "loin," like pork loin and sirloin, are winners. Skip the skin on poultry.
Steer clear of foods that contain large amounts of added sugars. Drink water instead of soda or fruit punch. Avoid high-calorie snack foods like cookies, cake, and ice cream.

Studies Show That Soluble Fiber May Help Lower Cholesterol More
By Jennifer Moll, About.com
Updated: May 27, 2009
About.com Health's Disease and Condition content is reviewed by the Medical Review Board
There are two types of fiber: soluble fiber and insoluble fiber. While both of these are important to include in your diet, studies have shown that one type of fiber can also help to lower your cholesterol.
We have already known some of the other heatlhy benefits that fiber has to offer. It helps with normal bowel function and it adds bulk to foods to make you feel fuller. However, there is evidence of another, essential benefit that fiber may have is that it can improve your heart health.
Types of Fiber
Although there are several forms of fiber, they can be classified into two major groups: soluble fiber and insoluble fiber. While both are good for the body, only one group has been shown to be beneficial in lowering your cholesterol.
Soluble fiber can be dissolved in water and forms a gel-like consistency in the digestive tract. On the other hand, insoluble fiber cannot be dissolved in water, so it passes through the digestive tract relatively unchanged. When it comes to your heart health, it appears that only soluble fiber is beneficial in lowering your cholesterol. In fact, studies have shown that consuming 10 to 25 grams soluble fiber a day can lower cholesterol by 18%.
However, it appears to only lower your “bad” cholesterol (LDL) –- your “good” cholesterol (HDL) and triglycerides are only minimally, if at all, affected by soluble fiber. Additionally, insoluble fiber does not appear to affect cholesterol levels, but it is important in maintaining a healthy colon.
Where Can I Get Soluble Fiber?
A variety of foods contain soluble fiber. By consuming the recommended amounts of fruits, vegetables, whole grains, and legumes in the Food Pyramid, you should be able to obtain the recommended amount of soluble fiber each day.
While fiber supplements can be used to fulfill this requirement, it is not recommended that you use them as substitute for eating a healthy . Fruits and vegetables also contain important nutrients, such as vitamins, that cannot be obtained through a fiber supplement.

DSM's fourth edition
There's an awful lot of money to be made from compulsive shopping, judging by the career of Madeleine Wickham. Her Shopaholic series, written under the pen name Sophie Kinsella, is required reading for chick-lit enthusiasts, and the romantic comedy Confessions of a Shopaholic, the first of several planned big-screen adaptations, grossed more than $100 million worldwide. While the film, starring Isla Fisher, isn't terribly funny, it does make the valid point that to enjoy shopping for elegant clothes isn't a pathology. It's a style.
The American Psychiatric Association risks losing sight of that distinction by grimly—and rather inexpertly—debating whether avid shopping should be considered a sign of mental illness. The fifth edition of the association's Diagnostic and Statistical Manual of Mental Disorders is expected in 2012. The APA isn't just deciding the fate of shopaholics; it's also debating whether overuse of the Internet, "excessive" sexual activity, apathy, and even prolonged bitterness should be viewed, quite seriously, as brain "disorders." If you spend hours online, have sex more frequently than aging psychiatrists, and moan incessantly that the federal government can't account for all its TARP funds, take heed: You may soon be classed among the 48 million Americans the APA already considers mentally ill.

Shakespeare divided life into "seven ages". In Hinduism, human life is believed to comprise four stages. These are called "ashramas" and every man should ideally go through each of these stages:
The First Ashrama - "Brahmacharya" or the Student Stage
The Second Ashrama - "Grihastha" or the Householder Stage
The Third Ashrama - "Vanaprastha" or the Hermit Stage
The Fourth Ashrama - "Sannyasa" or the Wandering Ascetic Stage
Brahmacharya - The Celibate Student:
This is a period of formal education. It lasts until the age of 25, during which, the young male leaves home to stay with a guru and attain both spiritual and practical knowledge. During this period, he is called a brahmachari, and is prepared for his future profession, as well as for his family, and social and religious life ahead.
Grihastha - The Married Family Man:
This period begins when a man gets married, and undertakes the responsibility for earning a living and supporting his family. At this stage, Hinduism supports the pursuit of wealth (artha) as a necessity, and indulgence in sexual pleasure (kama), under certain defined social and cosmic norms. This ashrama lasts until around the age of 50. According to the Laws of Manu, when a person's skin wrinkles and his hair greys, he should go out into the forest. However, in real life, most Hindus are so much in love with this second ashrama that the Grihastha stage lasts a lifetime!
Vanaprastha - The Hermit in Retreat:
This stage of a man begins when his duty as a householder comes to an end: He has become a grandfather, his children are grown up, and have established lives of their own. At this age, he should renounce all physical, material and sexual pleasures, retire from his social and professional life, leave his home, and go to live in a forest hut, spending his time in prayers. He is allowed to take his wife along, but is supposed to maintain little contact with the family. This kind of life is indeed very harsh and cruel for an aged person. No wonder, this third ashrama is now nearly obsolete.
Sannyasa - The Wandering Recluse:
At this stage, a man is supposed to be totally devoted to God. He is a sannyasi, he has no home, no other attachment; he has renounced all desires, fears and hopes, duties and responsibilities. He is virtually merged with God, all his worldly ties are broken, and his sole concern becomes attaining moksha, or release from the circle of birth and death. (Suffice it to say, very few Hindu men can go up to this stage of becoming a complete ascetic.) When he dies, the funeral ceremonies (Pretakarma) are performed by his son and heir.
What About Women?:
Although these ashramas are predominantly designed for the male, females too have a vital role to play in each one of them. So women are not actually excluded because they are always supposed to have an active social and religious life at home. However, a woman's role is of a dependent nature since, traditionally, they need the protection of a responsible male at every stage of life.
History of Ashramas:
This system of ashramas is believed to be prevalent since the 5th century BCE in Hindu society. However, historians say that these stages of life were always viewed more as 'ideals' than as common practice. According to one scholar, even in its very beginnings, after the first ashrama, a young adult could choose which of the other ashramas he would wish to pursue for the rest of his life. Today, it is not expected that a Hindu male should go through the four stages, but it still stands as an important "pillar" of Hindu socio-religious tradition.

///////////////The Good Life: Where Psychology Stands On Living Well
ScienceDaily (July 25, 2009) — Unfortunately for us, there is no formula for fulfillment or guide to life satisfaction; however, humans have turned to philosophy, religion and science time and again for answers to our existential questions. We may have come a long way since Confucius and Plato, and science continues to piece together some of the answers, but what have we learned so far?
Psychologists Nansook Park and Christopher Peterson from the University of Michigan turned to their own field to ask, "What is a good life and how can we achieve and sustain it?" In their article recently published in Perspectives in Psychological Science, a journal of the Association for Psychological Science, the authors explored the many ways psychology has contributed to, and continues to research, the science of living well.
So far we have learned from psychology that a good life includes experiencing more positive than negative feelings, feeling like your life has been lived well, continually using your talents and strengths, having close interpersonal relationships, being engaged at work and other activities, being a part of a social community, perceiving that life has a meaning, and feeling healthy and safe. And while these conclusions may seem like common sense, we as humans fall short on knowing just how to obtain and maintain these qualities.
Psychology still has a ways to go until the perfect formula for a good life is found. As Park and Peterson put it, "At present, psychology knows more about people's problems and how to solve them than it does about what it means to live well and how to encourage and maintain such a life." They suggest researchers across all disciplines of psychology come together and collaborate on their findings, perhaps pulling together a more complete picture of the human experience.
"In speaking about the psychological good life, we are fond of saying that other people matter," the authors concluded, "It appears that other people matter in science as well."

//////////////.......Ants more rational than humans

In a study released online on July 22 in the journal Proceedings of the Royal Society: Biological Sciences, researchers at Arizona State University and Princeton University show that ants can accomplish a task more rationally than our – multimodal, egg-headed, tool-using, bipedal, opposing-thumbed – selves. This is not the case of humans being "stupider" than ants. Humans and animals simply often make irrational choices when faced with very challenging decisions, note the study's architects Stephen Pratt and Susan Edwards.
"This paradoxical outcome is based on apparent constraint: most individual ants know of only a single option, and the colony's collective choice self-organizes from interactions among many poorly-informed ants," says Pratt, an assistant professor in the School of Life Sciences in ASU's College of Liberal Arts and Sciences.
///////////////////Feeling stressed? Then try savoring the scent of lemon, mango, lavender, or other fragrant plants. Scientists in Japan are reporting the first scientific evidence that inhaling certain fragrances alter gene activity and blood chemistry in ways that can reduce stress levels. Their study appears in ACS' Journal of Agricultural and Food Chemistry, a bi-weekly publication.
In the new study, Akio Nakamura and colleagues note that people have inhaled the scent of certain plants since ancient times to help reduce stress, fight inflammation and depression, and induce sleep. Aromatherapy, the use of fragrant plant oils to improve mood and health, has become a popular form of alternative medicine today. And linalool is one of the most widely used substances to soothe away emotional stress. Until now, however, linalool's exact effects on the body have been a deep mystery.
The scientists exposed lab rats to stressful conditions while inhaling and not inhaling linalool. Linalool returned stress-elevated levels of neutrophils and lymphocytes — key parts of the immune system — to near-normal levels. Inhaling linalool also reduced the activity of more than 100 genes that go into overdrive in stressful situations. The findings could form the basis of new blood tests for identifying fragrances that can soothe stress, the researchers say.

///////////////Compared with seasonal flu, a flu pandemic is likely to affect 25-50% of the population. In past pandemics those under the age of five and those over the age of 50 experienced the greatest severity in illness. There is likely to be increased morbidity and mortality in very young children particularly those with underlying health conditions. To date, case fatality of swine flu is between 0.1 and 0.4%.
It is also important to recognise that flu in young children may present differently to adults, with symptoms similar to those of other serious treatable illnesses such as meningitis. Care should be taken not to confuse the presentation of this and other conditions with the symptoms of flu.
It is anticipated that the number of cases is likely to increase into August 2009, with a likely a further increase in the frequency of cases and severity of presentation during the winter of 2009/10. Clearly there are implications for services beyond the need to manage and treat cases, such as staff shortages and implications for patients with long term conditions or those requiring specialty services.

We Are All Africans
All non-African females are descendants of L3 line from Africa, and males have Y chromosome M-168
Nayan Chanda
Businessworld, 21 July 2009
Sweden’s well-known author Lasse Berg often begins his book talk with an attention-getter: “I am glad to see so many Africans in the room”. it invariably makes his (largely blond and Nordic) audience turn around to see where all the Africans are. Of course, Berg means everyone present. The author of Dawn over Kalahari: How Man Became Man proceeds to tell the story of how all humanity emerged out of the so-called dark continent and populated the earth.
I think of Berg’s message when I read about an African student in Delhi being harassed by catcalls referring to his dark skin — kalia, kaala, habshi — or for that matter Indians from the North-east being derided as ‘chinki’ for their Chinese look. This is not different from the discrimination faced by Indian students in Australia who have recently been victims of “curry bashing”. Such racist insults seem to be increasing, or perhaps becoming more visible as the world becomes more integrated than ever. The gap between our knowledge of who we are and how we treat each other is as vast as it is stark.
Often these racial incidents are dismissed by the elite as acts of hoodlums or narrow-minded individuals. Surely, we all know humanity is one. Even leaving philosophical magnanimity or liberalism to one side, there is the simple biological fact that in every cell of our body we carry evidence of our common African origins. The startling 1987 discovery of our common origin by Allan Wilson and Rebecca Cann by studying mtDNA (the maternal DNA) from samples dispersed all over the world led Newsweek to run a cover story with an image of an African Adam and Eve. In the ensuing years, massive amounts of genetic research has laid to rest any doubt about our African origin. While all non-African females are descendants of L3 line from Africa, our earliest common father was one with a Y chromosome marker, M-168.
Curious about my own forebears, I sent my DNA anonymously for testing. The results were startling. The report told me I was an Indian because I had M-52 marker, which is predominantly Indian. But the report also confirmed the earliest Y-chromosome in my DNA was the same M-168 — that every male on the planet carries in his cells. My ancestors reached India some 2,000 generations ago.
The scientific evidence that we share the same African ancestry has been around for over two decades. Yet, in speaking about this to audiences across four continents, while presenting my book Bound Together I have encountered great surprise, and some scepticism. For whatever reason, this dramatic scientific confirmation of our common origin appears not to have penetrated the consciousness of even the most well-educated. Will wider dissemination of the scientific facts make any difference to the racist sentiment? Perhaps not in the short term. But that should be more the reason to start with our children, and make our genetic history an essential part of school curriculum.
Wide diffusion of the fact that 99.9 per cent of all human DNA is the same and pigmentation and other physical attributes are literally skin-deep may, over time, make us more accepting of others who look different. The understanding that our multi-hued skin, shape of our eyes and forms of our body were sculpted by a millennia of climatic conditions and natural selection might also make us less tolerant of the hoodlums and ignoramuses who indulge in racial discrimination. Teachers might start by downloading an accessible article from the July 2008 issue of Scientific American (www.scientificamerican.com), so that they can share with students the story of our African journey. They might even encourage volunteers to send their DNA for testing deep ancestry through National Genographic project (genographic.nationalgeographic.com), and share the results with the whole school.
Knowledge has not prevented racism and other malignancies that infect us, but we cannot hope to eliminate the scourge without it. Just five years ago, most people had no knowledge, let alone concern about global warming. But accumulated scientific evidence and its diffusion on a wider scale has produced greater awareness. The fact is that globalisation has increased our interdependence and exposure to others. To reduce the friction that results from the close encounter with other members of human tribe, we need to internalise what Berg tells his audience: We are all blacks.

////////////////////New “Great Wall” of Sand Could Protect Two Billion People
The "desertification" of the Sahara plains has the potential to displace more than two billion people in the years to come. But one architect has a plan to stop it: building a giant wall of sand.
By Kathryn Hawkins. Posted on July 26 2009 Filed under General Interest | Green |
Sahara Desert. Image: iStockphoto
The Sahara Desert stretches on for 3.5 million square miles, almost as large as the entire continental United States—but, thanks to shifting sand dunes, scientists say that the desert wasteland has the potential to grow far, far bigger.
That would spell bad news for an entire third of the world’s population in adjacent areas including sub-Saharan Africa, China, and central Asian countries, which would eventually be displaced by the sand’s migration into their land, destroying farmland and other habitats.
The threat of global warming’s on everyone’s radar these days, but the sand migration, known as “desertification,” has the problem to become an even more monumental problem. According to a 2007 UN report, the issue is “the greatest environmental challenge of our times.”
“It affects about 140 countries,” architect Magnus Larsson told BBC News. If desertification causes all of these inhabitants to evacuate, it could spell disaster for the planet.
But Larsson has a plan: at this year’s TED Conference, he spoke of his vision of creating a “Great Wall” built out of sand, which would prevent the desert from spreading. To keep the wall from blowing down, it would be sealed with Bacilius pasteuri, a type of bacteria found naturally in wetlands.
“It is a microorganism which chemically produces calcite - a kind of natural cement,” said Larsson.
Such a wall would take many years to plan and build, but Larsson is hopeful that his life-saving idea will have legs.
“It’s a beginning, it’s a vision; if nothing else I would like this scheme to initiate a discussion,” he said.

Abstract
BACKGROUND: Consumption of nuts has been associated with a decreased risk of cardiovascular disease events and death. Walnuts in particular have a unique profile: they are rich in polyunsaturated fatty acids, which may improve blood lipids and other cardiovascular disease risk factors. OBJECTIVES: We aimed to conduct a literature review and a meta-analysis to combine the results from several trials and to estimate the effect of walnuts on blood lipids. DESIGN: Literature databases were searched for published trials that compared a specifically walnut-enhanced diet with a control diet. We conducted a random-effects meta-analysis of weighted mean differences (WMDs) of lipid outcomes.
RESULTS: Thirteen studies representing 365 participants were included in the analysis. Diets lasted 4-24 wk with walnuts providing 10-24% of total calories. When compared with control diets, diets supplemented with walnuts resulted in a significantly greater decrease in total cholesterol and in LDL-cholesterol concentrations (total cholesterol: WMD = -10.3 mg/dL, P < 0.001; LDL cholesterol: WMD = -9.2 mg/dL, P < 0.001). HDL cholesterol and triglycerides were not significantly affected by walnut diets more than with control diets (HDL cholesterol: WMD = -0.2, P = 0.8; triglycerides: WMD = -3.9, P = 0.3). Other results reported in the trials indicated that walnuts provided significant benefits for certain antioxidant capacity and inflammatory markers and had no adverse effects on body weight [body mass index (kg/m(2)): WMD = -0.4, P = 0.5; weight (kg): WMD = -0.05, P = 0.97].
CONCLUSIONS: Overall, high-walnut-enriched diets significantly decreased total and LDL cholesterol for the duration of the short-term trials. Larger and longer-term trials are needed to address the effects of walnut consumption on cardiovascular risk and body weight.

Abstract
OBJECTIVE: The role of antibiotic therapy in managing acute bacterial sinusitis (ABS) in children is controversial. The purpose of this study was to determine the effectiveness of high-dose amoxicillin/potassium clavulanate in the treatment of children diagnosed with ABS.
METHODS: This was a randomized, double-blind, placebo-controlled study. Children 1 to 10 years of age with a clinical presentation compatible with ABS were eligible for participation. Patients were stratified according to age (<6 or >or=6 years) and clinical severity and randomly assigned to receive either amoxicillin (90 mg/kg) with potassium clavulanate (6.4 mg/kg) or placebo. A symptom survey was performed on days 0, 1, 2, 3, 5, 7, 10, 20, and 30. Patients were examined on day 14. Children`s conditions were rated as cured, improved, or failed according to scoring rules.
RESULTS: Two thousand one hundred thirty-five children with respiratory complaints were screened for enrollment; 139 (6.5%) had ABS. Fifty-eight patients were enrolled, and 56 were randomly assigned. The mean age was 66 +/- 30 months. Fifty (89%) patients presented with persistent symptoms, and 6 (11%) presented with nonpersistent symptoms. In 24 (43%) children, the illness was classified as mild, whereas in the remaining 32 (57%) children it was severe. Of the 28 children who received the antibiotic, 14 (50%) were cured, 4 (14%) were improved, 4 (14%) experienced treatment failure, and 6 (21%) withdrew. Of the 28 children who received placebo, 4 (14%) were cured, 5 (18%) improved, and 19 (68%) experienced treatment failure. Children receiving the antibiotic were more likely to be cured (50% vs 14%) and less likely to have treatment failure (14% vs 68%) than children receiving the placebo.
CONCLUSIONS: ABS is a common complication of viral upper respiratory infections. Amoxicillin/potassium clavulanate results in significantly more cure

//////////////////..........Should we be promoting safer cigarettes?
Posted by Northern Doctor at 19/7/2009 9:09 PM BST
Take a moment to take a deep drag on a few breathtaking statistics. Across the world approximately 1.3 billion people use tobacco products and by 2030 it is estimated that 10 million people will die annually from smoking-related diseases and 70% of these deaths will be in developing countries. We’ve known about the harmful effects of smoking for over 50 years and yet over that same period 6 million Britons have died of tobacco-related disease. Is there anything else we can do to reduce this burden?
New Scientist ran an article in June: Can smoking ever be made safe? Big Tobacco is working hard to come up with safer cigarettes. They are modifying filters, manipulating tobacco blends and measuring biomarkers in a bid to produce minimise harm. But is there really a place for a harm-reduction approach to cigarettes? As a doctor all I really promote is an abstinence model. I invest little effort in encouraging smokers to smoke less in those that can’t or won’t stop.
This is in stark contrast to my approach with heroin users. I prescribe methadone but even if abstinence isn’t reached I remain confident that it is likely to be helping them. I’ll even give advice on how to inject safely or other measures to reduce harm.
It’s no secret that it’s hard to stop smoking. Bandolier did an interesting little analysis of trials which included smokers and heroin addicts. They asked: which is the most addictive? In a rather elegant twist they looked at the cessation rates in the placebo arms of all the relevant trials. Cessation rates for smokers were around 8-9% yet for opiates users were around 43%. No surprises there - smoking is extraordinarily difficult to stop. Even in those that are highly motivated 12 month cessation rates are often around 10%. Opposing a harm reduction approach might be doing a grave disservice to those that just find it too tough.
The accompanying New Scientist editorial suggests:
Abstinence cannot be the only policy, however. Pragmatists will see the sense of safer cigarettes. There is a hard core of people who cannot or will not give up, and safer cigarettes could also help in poorer parts of the world, where more and more people are taking up smoking
My first reaction is not to trust Big Tobacco. It would clearly be an understatement to say they have a self-interest. Any evidence from the tobacco industry suggesting safer cigarettes will have to be filtered with great care but perhaps we shouldn't dismiss it out of hand.

Shakespeare divided life into "seven ages". In Hinduism, human life is believed to comprise four stages. These are called "ashramas" and every man should ideally go through each of these stages:
The First Ashrama - "Brahmacharya" or the Student Stage
The Second Ashrama - "Grihastha" or the Householder Stage
The Third Ashrama - "Vanaprastha" or the Hermit Stage
The Fourth Ashrama - "Sannyasa" or the Wandering Ascetic Stage
Brahmacharya - The Celibate Student:
This is a period of formal education. It lasts until the age of 25, during which, the young male leaves home to stay with a guru and attain both spiritual and practical knowledge. During this period, he is called a brahmachari, and is prepared for his future profession, as well as for his family, and social and religious life ahead.
Grihastha - The Married Family Man:
This period begins when a man gets married, and undertakes the responsibility for earning a living and supporting his family. At this stage, Hinduism supports the pursuit of wealth (artha) as a necessity, and indulgence in sexual pleasure (kama), under certain defined social and cosmic norms. This ashrama lasts until around the age of 50. According to the Laws of Manu, when a person's skin wrinkles and his hair greys, he should go out into the forest. However, in real life, most Hindus are so much in love with this second ashrama that the Grihastha stage lasts a lifetime!
Vanaprastha - The Hermit in Retreat:
This stage of a man begins when his duty as a householder comes to an end: He has become a grandfather, his children are grown up, and have established lives of their own. At this age, he should renounce all physical, material and sexual pleasures, retire from his social and professional life, leave his home, and go to live in a forest hut, spending his time in prayers. He is allowed to take his wife along, but is supposed to maintain little contact with the family. This kind of life is indeed very harsh and cruel for an aged person. No wonder, this third ashrama is now nearly obsolete.
Sannyasa - The Wandering Recluse:
At this stage, a man is supposed to be totally devoted to God. He is a sannyasi, he has no home, no other attachment; he has renounced all desires, fears and hopes, duties and responsibilities. He is virtually merged with God, all his worldly ties are broken, and his sole concern becomes attaining moksha, or release from the circle of birth and death. (Suffice it to say, very few Hindu men can go up to this stage of becoming a complete ascetic.) When he dies, the funeral ceremonies (Pretakarma) are performed by his son and heir.
What About Women?:
Although these ashramas are predominantly designed for the male, females too have a vital role to play in each one of them. So women are not actually excluded because they are always supposed to have an active social and religious life at home. However, a woman's role is of a dependent nature since, traditionally, they need the protection of a responsible male at every stage of life.
History of Ashramas:
This system of ashramas is believed to be prevalent since the 5th century BCE in Hindu society. However, historians say that these stages of life were always viewed more as 'ideals' than as common practice. According to one scholar, even in its very beginnings, after the first ashrama, a young adult could choose which of the other ashramas he would wish to pursue for the rest of his life. Today, it is not expected that a Hindu male should go through the four stages, but it still stands as an important "pillar" of Hindu socio-religious tradition.

///////////////The Good Life: Where Psychology Stands On Living Well
ScienceDaily (July 25, 2009) — Unfortunately for us, there is no formula for fulfillment or guide to life satisfaction; however, humans have turned to philosophy, religion and science time and again for answers to our existential questions. We may have come a long way since Confucius and Plato, and science continues to piece together some of the answers, but what have we learned so far?
Psychologists Nansook Park and Christopher Peterson from the University of Michigan turned to their own field to ask, "What is a good life and how can we achieve and sustain it?" In their article recently published in Perspectives in Psychological Science, a journal of the Association for Psychological Science, the authors explored the many ways psychology has contributed to, and continues to research, the science of living well.
So far we have learned from psychology that a good life includes experiencing more positive than negative feelings, feeling like your life has been lived well, continually using your talents and strengths, having close interpersonal relationships, being engaged at work and other activities, being a part of a social community, perceiving that life has a meaning, and feeling healthy and safe. And while these conclusions may seem like common sense, we as humans fall short on knowing just how to obtain and maintain these qualities.
Psychology still has a ways to go until the perfect formula for a good life is found. As Park and Peterson put it, "At present, psychology knows more about people's problems and how to solve them than it does about what it means to live well and how to encourage and maintain such a life." They suggest researchers across all disciplines of psychology come together and collaborate on their findings, perhaps pulling together a more complete picture of the human experience.
"In speaking about the psychological good life, we are fond of saying that other people matter," the authors concluded, "It appears that other people matter in science as well."

//////////////.......Ants more rational than humans

In a study released online on July 22 in the journal Proceedings of the Royal Society: Biological Sciences, researchers at Arizona State University and Princeton University show that ants can accomplish a task more rationally than our – multimodal, egg-headed, tool-using, bipedal, opposing-thumbed – selves. This is not the case of humans being "stupider" than ants. Humans and animals simply often make irrational choices when faced with very challenging decisions, note the study's architects Stephen Pratt and Susan Edwards.
"This paradoxical outcome is based on apparent constraint: most individual ants know of only a single option, and the colony's collective choice self-organizes from interactions among many poorly-informed ants," says Pratt, an assistant professor in the School of Life Sciences in ASU's College of Liberal Arts and Sciences.
///////////////////Feeling stressed? Then try savoring the scent of lemon, mango, lavender, or other fragrant plants. Scientists in Japan are reporting the first scientific evidence that inhaling certain fragrances alter gene activity and blood chemistry in ways that can reduce stress levels. Their study appears in ACS' Journal of Agricultural and Food Chemistry, a bi-weekly publication.
In the new study, Akio Nakamura and colleagues note that people have inhaled the scent of certain plants since ancient times to help reduce stress, fight inflammation and depression, and induce sleep. Aromatherapy, the use of fragrant plant oils to improve mood and health, has become a popular form of alternative medicine today. And linalool is one of the most widely used substances to soothe away emotional stress. Until now, however, linalool's exact effects on the body have been a deep mystery.
The scientists exposed lab rats to stressful conditions while inhaling and not inhaling linalool. Linalool returned stress-elevated levels of neutrophils and lymphocytes — key parts of the immune system — to near-normal levels. Inhaling linalool also reduced the activity of more than 100 genes that go into overdrive in stressful situations. The findings could form the basis of new blood tests for identifying fragrances that can soothe stress, the researchers say.

In past pandemics those under the age of five and those over the age of 50 experienced the greatest severity in illness. There is likely to be increased morbidity and mortality in very young children particularly those with underlying health conditions. To date, case fatality of swine flu is between 0.1 and 0.4%.
It is also important to recognise that flu in young children may present differently to adults, with symptoms similar to those of other serious treatable illnesses such as meningitis. Care should be taken not to confuse the presentation of this and other conditions with the symptoms of flu.
It is anticipated that the number of cases is likely to increase into August 2009, with a likely a further increase in the frequency of cases and severity of presentation during the winter of 2009/10. Clearly there are implications for services beyond the need to manage and treat cases, such as staff shortages and implications for patients with long term conditions or those requiring specialty services.

We Are All Africans
All non-African females are descendants of L3 line from Africa, and males have Y chromosome M-168
Nayan Chanda
Businessworld, 21 July 2009
Sweden’s well-known author Lasse Berg often begins his book talk with an attention-getter: “I am glad to see so many Africans in the room”. it invariably makes his (largely blond and Nordic) audience turn around to see where all the Africans are. Of course, Berg means everyone present. The author of Dawn over Kalahari: How Man Became Man proceeds to tell the story of how all humanity emerged out of the so-called dark continent and populated the earth.
I think of Berg’s message when I read about an African student in Delhi being harassed by catcalls referring to his dark skin — kalia, kaala, habshi — or for that matter Indians from the North-east being derided as ‘chinki’ for their Chinese look. This is not different from the discrimination faced by Indian students in Australia who have recently been victims of “curry bashing”. Such racist insults seem to be increasing, or perhaps becoming more visible as the world becomes more integrated than ever. The gap between our knowledge of who we are and how we treat each other is as vast as it is stark.
Often these racial incidents are dismissed by the elite as acts of hoodlums or narrow-minded individuals. Surely, we all know humanity is one. Even leaving philosophical magnanimity or liberalism to one side, there is the simple biological fact that in every cell of our body we carry evidence of our common African origins. The startling 1987 discovery of our common origin by Allan Wilson and Rebecca Cann by studying mtDNA (the maternal DNA) from samples dispersed all over the world led Newsweek to run a cover story with an image of an African Adam and Eve. In the ensuing years, massive amounts of genetic research has laid to rest any doubt about our African origin. While all non-African females are descendants of L3 line from Africa, our earliest common father was one with a Y chromosome marker, M-168.
Curious about my own forebears, I sent my DNA anonymously for testing. The results were startling. The report told me I was an Indian because I had M-52 marker, which is predominantly Indian. But the report also confirmed the earliest Y-chromosome in my DNA was the same M-168 — that every male on the planet carries in his cells. My ancestors reached India some 2,000 generations ago.
The scientific evidence that we share the same African ancestry has been around for over two decades. Yet, in speaking about this to audiences across four continents, while presenting my book Bound Together I have encountered great surprise, and some scepticism. For whatever reason, this dramatic scientific confirmation of our common origin appears not to have penetrated the consciousness of even the most well-educated. Will wider dissemination of the scientific facts make any difference to the racist sentiment? Perhaps not in the short term. But that should be more the reason to start with our children, and make our genetic history an essential part of school curriculum.
Wide diffusion of the fact that 99.9 per cent of all human DNA is the same and pigmentation and other physical attributes are literally skin-deep may, over time, make us more accepting of others who look different. The understanding that our multi-hued skin, shape of our eyes and forms of our body were sculpted by a millennia of climatic conditions and natural selection might also make us less tolerant of the hoodlums and ignoramuses who indulge in racial discrimination. Teachers might start by downloading an accessible article from the July 2008 issue of Scientific American (www.scientificamerican.com), so that they can share with students the story of our African journey. They might even encourage volunteers to send their DNA for testing deep ancestry through National Genographic project (genographic.nationalgeographic.com), and share the results with the whole school.
Knowledge has not prevented racism and other malignancies that infect us, but we cannot hope to eliminate the scourge without it. Just five years ago, most people had no knowledge, let alone concern about global warming. But accumulated scientific evidence and its diffusion on a wider scale has produced greater awareness. The fact is that globalisation has increased our interdependence and exposure to others. To reduce the friction that results from the close encounter with other members of human tribe, we need to internalise what Berg tells his audience: We are all blacks.

////////////////////New “Great Wall” of Sand Could Protect Two Billion People
The "desertification" of the Sahara plains has the potential to displace more than two billion people in the years to come. But one architect has a plan to stop it: building a giant wall of sand.
By Kathryn Hawkins. Posted on July 26 2009 Filed under General Interest | Green |
Sahara Desert. Image: iStockphoto
The Sahara Desert stretches on for 3.5 million square miles, almost as large as the entire continental United States—but, thanks to shifting sand dunes, scientists say that the desert wasteland has the potential to grow far, far bigger.
That would spell bad news for an entire third of the world’s population in adjacent areas including sub-Saharan Africa, China, and central Asian countries, which would eventually be displaced by the sand’s migration into their land, destroying farmland and other habitats.
The threat of global warming’s on everyone’s radar these days, but the sand migration, known as “desertification,” has the problem to become an even more monumental problem. According to a 2007 UN report, the issue is “the greatest environmental challenge of our times.”
“It affects about 140 countries,” architect Magnus Larsson told BBC News. If desertification causes all of these inhabitants to evacuate, it could spell disaster for the planet.
But Larsson has a plan: at this year’s TED Conference, he spoke of his vision of creating a “Great Wall” built out of sand, which would prevent the desert from spreading. To keep the wall from blowing down, it would be sealed with Bacilius pasteuri, a type of bacteria found naturally in wetlands.
“It is a microorganism which chemically produces calcite - a kind of natural cement,” said Larsson.
Such a wall would take many years to plan and build, but Larsson is hopeful that his life-saving idea will have legs.
“It’s a beginning, it’s a vision; if nothing else I would like this scheme to initiate a discussion,” he said.

Abstract
BACKGROUND: Consumption of nuts has been associated with a decreased risk of cardiovascular disease events and death. Walnuts in particular have a unique profile: they are rich in polyunsaturated fatty acids, which may improve blood lipids and other cardiovascular disease risk factors. OBJECTIVES: We aimed to conduct a literature review and a meta-analysis to combine the results from several trials and to estimate the effect of walnuts on blood lipids. DESIGN: Literature databases were searched for published trials that compared a specifically walnut-enhanced diet with a control diet. We conducted a random-effects meta-analysis of weighted mean differences (WMDs) of lipid outcomes.
RESULTS: Thirteen studies representing 365 participants were included in the analysis. Diets lasted 4-24 wk with walnuts providing 10-24% of total calories. When compared with control diets, diets supplemented with walnuts resulted in a significantly greater decrease in total cholesterol and in LDL-cholesterol concentrations (total cholesterol: WMD = -10.3 mg/dL, P < 0.001; LDL cholesterol: WMD = -9.2 mg/dL, P < 0.001). HDL cholesterol and triglycerides were not significantly affected by walnut diets more than with control diets (HDL cholesterol: WMD = -0.2, P = 0.8; triglycerides: WMD = -3.9, P = 0.3). Other results reported in the trials indicated that walnuts provided significant benefits for certain antioxidant capacity and inflammatory markers and had no adverse effects on body weight [body mass index (kg/m(2)): WMD = -0.4, P = 0.5; weight (kg): WMD = -0.05, P = 0.97].
CONCLUSIONS: Overall, high-walnut-enriched diets significantly decreased total and LDL cholesterol for the duration of the short-term trials. Larger and longer-term trials are needed to address the effects of walnut consumption on cardiovascular risk and body weight.

Abstract
OBJECTIVE: The role of antibiotic therapy in managing acute bacterial sinusitis (ABS) in children is controversial. The purpose of this study was to determine the effectiveness of high-dose amoxicillin/potassium clavulanate in the treatment of children diagnosed with ABS.
METHODS: This was a randomized, double-blind, placebo-controlled study. Children 1 to 10 years of age with a clinical presentation compatible with ABS were eligible for participation. Patients were stratified according to age (<6 or >or=6 years) and clinical severity and randomly assigned to receive either amoxicillin (90 mg/kg) with potassium clavulanate (6.4 mg/kg) or placebo. A symptom survey was performed on days 0, 1, 2, 3, 5, 7, 10, 20, and 30. Patients were examined on day 14. Children`s conditions were rated as cured, improved, or failed according to scoring rules.
RESULTS: Two thousand one hundred thirty-five children with respiratory complaints were screened for enrollment; 139 (6.5%) had ABS. Fifty-eight patients were enrolled, and 56 were randomly assigned. The mean age was 66 +/- 30 months. Fifty (89%) patients presented with persistent symptoms, and 6 (11%) presented with nonpersistent symptoms. In 24 (43%) children, the illness was classified as mild, whereas in the remaining 32 (57%) children it was severe. Of the 28 children who received the antibiotic, 14 (50%) were cured, 4 (14%) were improved, 4 (14%) experienced treatment failure, and 6 (21%) withdrew. Of the 28 children who received placebo, 4 (14%) were cured, 5 (18%) improved, and 19 (68%) experienced treatment failure. Children receiving the antibiotic were more likely to be cured (50% vs 14%) and less likely to have treatment failure (14% vs 68%) than children receiving the placebo.
CONCLUSIONS: ABS is a common complication of viral upper respiratory infections. Amoxicillin/potassium clavulanate results in significantly more cure

//////////////////..........Should we be promoting safer cigarettes?
Posted by Northern Doctor at 19/7/2009 9:09 PM BST
Take a moment to take a deep drag on a few breathtaking statistics. Across the world approximately 1.3 billion people use tobacco products and by 2030 it is estimated that 10 million people will die annually from smoking-related diseases and 70% of these deaths will be in developing countries. We’ve known about the harmful effects of smoking for over 50 years and yet over that same period 6 million Britons have died of tobacco-related disease. Is there anything else we can do to reduce this burden?
New Scientist ran an article in June: Can smoking ever be made safe? Big Tobacco is working hard to come up with safer cigarettes. They are modifying filters, manipulating tobacco blends and measuring biomarkers in a bid to produce minimise harm. But is there really a place for a harm-reduction approach to cigarettes? As a doctor all I really promote is an abstinence model. I invest little effort in encouraging smokers to smoke less in those that can’t or won’t stop.
This is in stark contrast to my approach with heroin users. I prescribe methadone but even if abstinence isn’t reached I remain confident that it is likely to be helping them. I’ll even give advice on how to inject safely or other measures to reduce harm.
It’s no secret that it’s hard to stop smoking. Bandolier did an interesting little analysis of trials which included smokers and heroin addicts. They asked: which is the most addictive? In a rather elegant twist they looked at the cessation rates in the placebo arms of all the relevant trials. Cessation rates for smokers were around 8-9% yet for opiates users were around 43%. No surprises there - smoking is extraordinarily difficult to stop. Even in those that are highly motivated 12 month cessation rates are often around 10%. Opposing a harm reduction approach might be doing a grave disservice to those that just find it too tough.
The accompanying New Scientist editorial suggests:
Abstinence cannot be the only policy, however. Pragmatists will see the sense of safer cigarettes. There is a hard core of people who cannot or will not give up, and safer cigarettes could also help in poorer parts of the world, where more and more people are taking up smoking
My first reaction is not to trust Big Tobacco. It would clearly be an understatement to say they have a self-interest. Any evidence from the tobacco industry suggesting safer cigarettes will have to be filtered with great care but perhaps we shouldn't dismiss it out of hand.

//////////////In Prison
I cried out for the pain of man,
I cried out for my bitter wrath
Against the hopeless life that ran
For ever in a circling path
From death to death since all began;
Till on a summer night
I lost my way in the pale starlight
And saw our planet, far and small,
Through endless depths of nothing fall
A lonely pin-prick spark of light,
Upon the wide, enfolding night,
With leagues on leagues of stars above it,
And powdered dust of stars below—
Dead things that neither hate nor love it
Not even their own loveliness can know,
Being but cosmic dust and dead.
And if some tears be shed,
Some evil God have power,
Some crown of sorrow sit
Upon a little world for a little hour—
Who shall remember? Who shall care for it?

///////////////FROM COSMIC DUST TO COSMIC DUST
////////////In his landmark work of economic theory, the 1899 Theory of the Leisure Class, Thorsten Veblen offered his ideas on how modern society could trace its origins in the dawn of humanity. Veblen looked beyond the complexities of life in his own modern day in order to map ancient human customs, needs, and drives onto what he saw in his peers. Veblen was fascinated by what he called the "leisure class," the well-to-do class of people whose wealth allowed them to live as though every day were a holiday. His work posed an eye-opening question: does the leisure-class have a purpose or a role in human life and culture? Though startling even to this day, Veblen's unconventional approach offers incredible insight into human behavior across the ages.

////////////////New Research Shows: Neurofeedback Is An 'Evidence-Based' Treatment For ADHD
Neurofeedback - also called EEG Biofeedback - is a method used to train brain activity in order to normalize Brain function and treat psychiatric disorders. This treatment method has gained interest over the last 10 years, however the question whether this treatment should be regarded as an Evidence-Based treatment was unanswered until now.
///////////////A Little Inspiration
People are often unreasonable, illogical, and self-centered;
Forgive them anyway.
If you are kind, people may accuse you of selfish, ulterior motives;
Be kind anyway.
If you are successful, you will win some false friends and some true enemies;
Succeed anyway.
If you are honest and frank, people may cheat you;
Be honest and frank anyway.
What you spend years building, someone could destroy overnight;
Build anyway.
If you find serenity and happiness, they may be jealous;
Be happy anyway.
The good you do today, people will often forget tomorrow;
Do good anyway.
Give the world the best you have, and it may never be enough;
Give the world the best you've got anyway.
You see, in the final analysis, It is between you and God;
It never was between you and them anyway.

//////////////////////Is lumbar puncture necessary for evaluation of early neonatal sepsis?
Report by Edited by
B Ray, Specialist Registrar1, J Mangalore2, C Harikumar2 and A Tuladhar2
Edited by Bob Phillips

2 University Hospital of North Tees, Stockton, UK
A newborn baby born at 37 weeks is noted to be unwell at 18 h postnatally. The mother gives a history of prolonged rupture of membranes for 36 h. The baby is feeding poorly and is jittery, with a temperature of 38°C. A clinical diagnosis of early sepsis is made and lumbar puncture is suggested on the ward round as a part of sepsis evaluation. Several publications on the use of lumbar puncture in late-onset sepsis, including a recent review article by Malbon et al,1 suggest that lumbar puncture is an important method of investigation and should be considered in babies for >48 h old, with suspected sepsis.
We wonder whether there is sufficient evidence to justify lumbar puncture in early sepsis.
Structured clinical question
In a newborn (patient), is lumbar puncture (intervention) necessary to rule out meningitis in suspected sepsis (outcome) in the first few days of life (0–3 days)?
Search strategy and outcome
Search date: September 2005
Cochrane Library: Nil relevant
Medline: 1950–to date; Embase: 1974–to date; Cinhal: 1982–to date via Dialog Datastar
Search terms: (Neonatal ADJ sepsis or Neonatal ADJ septicaemia or Neonatal ADJ meningitis or meningitis and infant–newborn# or Early ADJ sepsis, or Early ADJ septicaemia) and (Lumbar ADJ puncture or LP or Spinal ADJ tap or CSF ADJ examination). Limit to English language and newborn infants from birth to 1 month.
Total number of hits: 51
Cross-references obtained: 6
Total number: 57, of which 5 studies were eligible.2–7
Commentary
Lumbar puncture has always been an invaluable tool to diagnose meningitis. In the neonatal period, septicaemia can be indistinguishable from meningitis. The overall incidence of neonatal meningitis is 0.25–1.0 per 1000 live births.7,8
Practice varies between hospital units as regards early sepsis evaluation. Although blood culture has been regarded as an essential component of sepsis screen, the role of lumbar puncture is debatable especially in the first 72 h of life. Previously published data showed that neonatal septicaemia can coexist with meningitis in up to 30% of patients.2 On the other hand, lumbar puncture can be associated with major risks including hypoxaemia, clinical deterioration and many other hazards in small and sick babies.9,10 Moreover, in about 30% of patients, the cerebrospinal fluid tap could be traumatic or inadequate.9,11
Although many of the studies did not compare the incidence of meningitis between groups with early-onset sepsis presenting with symptoms and groups with suspected sepsis because of perinatal risk factors without any overt symptoms,Please confirm the changes made in the sentence the published literature shows the incidence of meningitis in asymptomatic newborns undergoing evaluation only because risk factors is virtually nil.12–14
The study by Visser et al2 observed a very high (1.8%) incidence of meningitis in babies within 72 h of life. This study also noted that in 15% of cases, blood culture was negative. Many of the later studies did not show such a high incidence.12,15 For example, studies by Ajayi and Mokuolu6 and Hendricks-Munoz and Shapiro4 looked at around 1700 babies but found no cases of meningitis. Even their long-term follow-up did not show any case of missed or partially treated meningitis. Two other similar studies,3,5 which looked at babies admitted with respiratory symptoms within 24 h of birth, also found a very low incidence of meningitis (only four cases of meningitis in > 1700 neonates evaluated with lumbar puncture). The statistically estimated maximum risk of meningitis in suspected early sepsis is only 1.1% and that in blood culture proved sepsis is 0–10.3%.
It seems that there is no need to carry out lumbar puncture in neonates suspected of early sepsis who are being evaluated purely for perinatal risk factors, or in those presenting with mild symptoms. It should still be undertaken in babies with severe illness or obviously where meningitis is strongly suspected.
Clinical bottom line
Overall incidence of neonatal meningitis is 0.25–1.0 per 1000 live births (grade A).
Uncontrolled studies suggest that meningitis is very uncommon in asymptomatic babies with only perinatal risk factors for sepsis, so in this group lumbar puncture can be safely omitted from the early sepsis screen (grade B).
In strongly suspected cases, lumbar puncture should be included in an examination of sepsis (grade B).

WTHOUT THE HPPY ENDINGS
///////////////Symbiosis and evolution
Leafhoppers protected by an army of meat ants
While historically, symbiosis has received less attention than other interactions such as predation or competition,[25] it is increasingly recognised as an important selective force behind evolution,[26][27] with many species having a long history of interdependent co-evolution.[28] In fact, the evolution of all eukaryotes (plants, animals, fungi, and protists) is believed under the endosymbiotic theory to have resulted from a symbiosis between various sorts of bacteria.[29][30][31]
[edit]Symbiogenesis
The biologist Lynn Margulis, famous for her work on endosymbiosis, contends that symbiosis is a major driving force behind evolution. She considers Darwin's notion of evolution, driven by competition, as incomplete and claims that evolution is strongly based on co-operation, interaction, and mutual dependence among organisms. According to Margulis and Dorion Sagan, "Life did not take over the globe by combat, but by networking."[32]
[edit]Co-evolution
Symbiosis played a major role in the co-evolution of flowering plants and the animals that pollinate them. Many plants that are pollinated by insects, bats, or birds have highly specialized flowers modified to promote pollination by a specific pollinator that is also correspondingly adapted. The first flowering plants in the fossil record had relatively simple flowers. Adaptive speciation quickly gave rise to many diverse groups of plants, and, at the same time, corresponding speciation occurred in certain insect groups. Some groups of plants developed nectar and large sticky pollen, while insects evolved more specialized morphologies to access and collect these rich food sources. In some taxa of plants and insects the relationship has become dependent,[33] where the plant species can only be pollinated by one species of insect. [34]

The Buddha's Last Instruction -- Mary Oliver
The Buddha's Last Instruction
"Make of yourself a light,"
said the Buddha,
before he died.
I think of this every morning
as the east begins
to tear off its many clouds
of darkness, to send up the first
signal - a white fan
streaked with pink and violet,
even green.
An old man, he lay down
between two sala trees,
and he might have said anything,
knowing it was his final hour.
The light burns upward,
it thickens and settles over the fields.
Around him, the villagers gathered
and stretched forward to listen.
Even before the sun itself
hangs, disattached, in the blue air,
I am touched everywhere
by its ocean of yellow waves.
No doubt he thought of everything
that had happened in his difficult life.
And then I feel the sun itself
as it blazes over the hills,
like a million flowers on fire -
clearly I'm not needed,
yet I feel myself turning
into something of inexplicable value.
Slowly, beneath the branches,
he raised his head.
He looked into the faces of that frightened crowd.

Stephen Hawking: Why Isn't the Milky Way "Crawling With Self-Designing Mechanical or Biological Life?"
In his famous lecture on Life in the Universe, Stephen Hawking asks: "What are the chances that we will encounter some alien form of life, as we explore the galaxy?"
If the argument about the time scale for the appearance of life on Earth is correct, Hawking says "there ought to be many other stars, whose planets have life on them. Some of these stellar systems could have formed 5 billion years before the Earth. So why is the galaxy not crawling with self-designing mechanical or biological life forms?"
Why hasn't the Earth been visited, and even colonized? Hawking asks. "I discount suggestions that UFO's contain beings from outer space. I think any visits by aliens, would be much more obvious, and probably also, much more unpleasant."
Hawking continues: "What is the explanation of why we have not been visited? \One possibility is that the argument, about the appearance of life on Earth, is wrong. Maybe the probability of life spontaneously appearing is so low, that Earth is the only planet in the galaxy, or in the observable universe, in which it happened. Another possibility is that there was a reasonable probability of forming self reproducing systems, like cells, but that most of these forms of life did not evolve intelligence."
We are used to thinking of intelligent life, as an inevitable consequence of evolution, Hawking emphasized, but it is more likely that evolution is a random process, with intelligence as only one of a large number of possible outcomes.
Intelligence, Hawking believes contrary to our human-centric existece, may not have any long-term survival value. In comparison the microbial world, will live on, even if all other life on Earth is wiped out by our actions. Hawking's main insight is that intelligence was an unlikely development for life on Earth, from the chronology of evolution: "It took a very long time, two and a half billion years, to go from single cells to multi-cell beings, which are a necessary precursor to intelligence. This is a good fraction of the total time available, before the Sun blows up. So it would be consistent with the hypothesis, that the probability for life to develop intelligence, is low. In this case, we might expect to find many other life forms in the galaxy, but we are unlikely to find intelligent life."
Another possibility is that there is a reasonable probability for life to form, and to evolve to intelligent beings, but at some point in their technological development "the system becomes unstable, and the intelligent life destroys itself. This would be a very pessimistic conclusion. I very much hope it isn't true."
Hawkling prefers another possibility: that there are other forms of intelligent life out there, but that we have been overlooked. If we should pick up signals from alien civilizations, Hawking warns,"we should have be wary of answering back, until we have evolved" a bit further. Meeting a more advanced civilization, at our present stage,' Hawking says "might be a bit like the original inhabitants of America meeting Columbus. I don't think they were better off for it."

... maybe truely intelligent life doesn't act the way humans do?
"For instance, on the planet Earth, man had always assumed that he was more intelligent than dolphins because he had achieved so much - the wheel, New York, wars and so on - whilst all the dolphins had ever done was muck about in the water having a good time. But conversely, the dolphins had always believed that they were far more intelligent than man - for precisely the same reasons." -

I think you only have to watch a wildlife documentary and see the spectacular variety of life on Earth (often in environments so hostile we'd previously thought nothing could live) to conclude that where ever life of some form is possible, it may be inevitable.
I favour the hypothesis that the universe is probably teaming with life and that our surveys so far are barely a drop in the ocean.
Another though occurs too. I don't subscribe to the idea of little green men in flying saucers. The idea that a super-advanced species would travel the gulf of space only to steal cows (or crash their ship) is pretty laughable.
... but I wonder could we even perceive the existence of a more advanced form of life? A species thousands, millions even billions of years more advanced than us would be so different. Would we be like ants trying to comprehend the human world?
Posted by: Alex Hardy | July 11, 2009 at 02:22 AM
Very similar ideas to those that I put forward in my two-part discussion on the possibility of alien life.
I think life is out there and is flourishing all over the universe. But intelligent life is (as Hawking says) a much more difficult proposition...

I consider it as if we're sperm trying to perceive what life as a human being would be like. From our perspective as human beings, we can't even imagine what a more advanced intelligence would be like, just as the sperm couldn't possibly imagine what a human is like. Until we, as a race make that journey to the next step of existence we're just sitting in a universal ballsack.

There is another possibility, one that Hawking didn't mention...
That the universe is teeming with life, that it there millions, even billions of intelligent and technological civilisations in the Galaxy... and the reason none of them has visit here, or even contacted us, is because Earth, and humans, are basically rather boring. That we are nothing at all special in comparison.
Not very flattering to our ego though...

Just the sheer numbers make it very likely that other life exists not only in the universe or our galaxy but somewhere in our inter-stellar neighborhood. As a matter of fact microbial life probably exists in our solar system. Even though we admitted the earth revolves around the sun some time ago human still have a very earth-centered point of view when it comes to looking at the universe which is rather silly given the size of it.

Just a few observations/ideas:
Stephen Hawking says: "I discount suggestions that UFO's contain beings from outer space. I think any visits by aliens, would be much more obvious, and probably also, much more unpleasant."
He has set up a VERY narrow lens through which to explain/interpret his thesis. There are many other possibilities (some of which we may not even imagine from our perspective). If aliens are are already here or at least visit what makes him think they would be much more obvious or unpleasant?
First let's assume they haven't always been here; for they could have played a much larger role in our historical/evolutionary development than we realize. If they only visit, they obviously would have technology to remain hidden beyond our wildest imaginations. There could also be more than one race visiting/interacting here on Earth. In that case, they would likely have a treaty excluding direct official contact. Also, if their interest is primarily scientific, it is likely that they would attempt to minimize their impact/influence on what they are studying. In short, there are many, many possibilities.
He also seems to lean toward the assumption that alien visitors will be hostile towards us. Again, this is a strong assumption that alters all further hypotheses. He may be right, and there is some anecdotal evidence to support this. But again, reality may be much more complicated--especially if there are more than one race involved.

We don't have much evidence, and so far that evidence is limited to one planet, so we are basically guessing. The comment that we might be in the condition of ants with regard to humans makes sense, though.
From the little bit of evidence we do have, there appear to be at least three "intelligent" species on this planet, and there is rapidly burgeoning evidence that problem-solving intelligence is widespread among at least endothermal species, so the thesis that "intelligence" is a rare result of evolution seems unlikely.
I'd suggest that evolution tends to increasing complexity in a logarithmic progression--which would account for the fact that the progression from unicellular to multicellular life took so long--one would expect succeeding stages to be shorter and shorter--and that complexity rather naturally tends to what we describe as intelligence.

Stephen Hawking is obviously much smarter than I am, so I hesitate to question his logic. However, there are a couple of things that I think he is over looking. First off, timing is everything. The Universe is roughly 13 billion years old. The Earth is about 5 billion. Our ability to understand the Universe is only a few hundred years old at most (you can argue that we still don't really understand it).
Who is to say that very advanced civilization did not exist a million years ago and has, for some reason, died out or is no longer looking outside its home planet for some reason.
Second, you can not escape the fact that the distance between stars in the galaxy/universe is very large. Intelligent life usually requires a great deal of resources to stay alive. Therefore, it is quite possible that it is very difficult for intelligent beings to travel the distances needed to visit other stars (at least not very often). It could be that intelligent life is fairly common, but the ability to visit other planets with intelligent life is very uncommon.
Given how pervasive life is on Earth, I find it inconceivable that it is not equally pervasive. It may be that intelligent life is uncommon, but I find that hard to believe as well since there are many species on Earth that are capable of more evolved thought.

I think life is out there and is flourishing all over the universe. But intelligent life is (as Hawking says) a much more difficult proposition...

So what about the intelligent communications and scripted messages pressed into the fields at Milk Hill near Avebury and Alton Barnes in southern England this summer?
There appear to be some forms of intelligent language or code in the energy imprints bent in the living plants, but can anyone read them?
Please take a look with an open mind and consider that the "impossible" might possibly be happening right in Stephen's backyard.
Images and information found at:

www.cropcircleconnector.com

cropcirclesandmore.com
-- and many other sites.
Help! Are these pleasant messages or warnings?
Who can read them and what might they say?

Ezikiel discribes a visit of alians in the bible, 'and they ascended to heavon on a pillar of fire' reminds me of the space shuttle.

I consider it as if we're sperm trying to perceive what life as a human being would be like. From our perspective as human beings, we can't even imagine what a more advanced intelligence would be like, just as the sperm couldn't possibly imagine what a human is like. Until we, as a race make that journey to the next step of existence we're just sitting in a universal ballsack.

It would be cool if we're the first to colonize the galaxy. I'd rather be Columbus myself... given the choice.

The guy who wrote this article is comma-happy.

There is another possibility, one that Hawking didn't mention...
That the universe is teeming with life, that it there millions, even billions of intelligent and technological civilisations in the Galaxy... and the reason none of them has visit here, or even contacted us, is because Earth, and humans, are basically rather boring. That we are nothing at all special in comparison.
Not very flattering to our ego though...

Just the sheer numbers make it very likely that other life exists not only in the universe or our galaxy but somewhere in our inter-stellar neighborhood. As a matter of fact microbial life probably exists in our solar system. Even though we admitted the earth revolves around the sun some time ago human still have a very earth-centered point of view when it comes to looking at the universe which is rather silly given the size of it.

"Why hasn't the Earth been visited, and even colonized? Hawking asks."
That seems to preclude the idea that we may be the colonizers.

Just a few observations/ideas:
Stephen Hawking says: "I discount suggestions that UFO's contain beings from outer space. I think any visits by aliens, would be much more obvious, and probably also, much more unpleasant."
He has set up a VERY narrow lens through which to explain/interpret his thesis. There are many other possibilities (some of which we may not even imagine from our perspective). If aliens are are already here or at least visit what makes him think they would be much more obvious or unpleasant?
First let's assume they haven't always been here; for they could have played a much larger role in our historical/evolutionary development than we realize. If they only visit, they obviously would have technology to remain hidden beyond our wildest imaginations. There could also be more than one race visiting/interacting here on Earth. In that case, they would likely have a treaty excluding direct official contact. Also, if their interest is primarily scientific, it is likely that they would attempt to minimize their impact/influence on what they are studying. In short, there are many, many possibilities.
He also seems to lean toward the assumption that alien visitors will be hostile towards us. Again, this is a strong assumption that alters all further hypotheses. He may be right, and there is some anecdotal evidence to support this. But again, reality may be much more complicated--especially if there are more than one race involved.

Whoever wrote this article needs to learn the appropriate placement of commas. For example, the following sentence:
"I think any visits by aliens, would be much more obvious, and probably also, much more unpleasant."
should read:
"I think any visits by aliens would be much more obvious, and probably also much more unpleasant."

We don't have much evidence, and so far that evidence is limited to one planet, so we are basically guessing. The comment that we might be in the condition of ants with regard to humans makes sense, though.
From the little bit of evidence we do have, there appear to be at least three "intelligent" species on this planet, and there is rapidly burgeoning evidence that problem-solving intelligence is widespread among at least endothermal species, so the thesis that "intelligence" is a rare result of evolution seems unlikely.
I'd suggest that evolution tends to increasing complexity in a logarithmic progression--which would account for the fact that the progression from unicellular to multicellular life took so long--one would expect succeeding stages to be shorter and shorter--and that complexity rather naturally tends to what we describe as intelligence.

The aliens that make the crop circles must be very small or very low in the power department , as we in B.C. have never witnessed a tree circle. This could be used to calibrate their probable size ,lol .On the subject of God . If one can believe in the invisible man in the sky. Whom knows and see's all . Then why not little crop circling green men . We have just as much evidence for either .

Stephen Hawking is obviously much smarter than I am, so I hesitate to question his logic. However, there are a couple of things that I think he is over looking. First off, timing is everything. The Universe is roughly 13 billion years old. The Earth is about 5 billion. Our ability to understand the Universe is only a few hundred years old at most (you can argue that we still don't really understand it).
Who is to say that very advanced civilization did not exist a million years ago and has, for some reason, died out or is no longer looking outside its home planet for some reason.
Second, you can not escape the fact that the distance between stars in the galaxy/universe is very large. Intelligent life usually requires a great deal of resources to stay alive. Therefore, it is quite possible that it is very difficult for intelligent beings to travel the distances needed to visit other stars (at least not very often). It could be that intelligent life is fairly common, but the ability to visit other planets with intelligent life is very uncommon.
Given how pervasive life is on Earth, I find it inconceivable that it is not equally pervasive. It may be that intelligent life is uncommon, but I find that hard to believe as well since there are many species on Earth that are capable of more evolved thought.
