///////////////////Giraffe-killing lions exploit paved roads
Posted: 20 Jun 2008 07:41 AM CDT
This is the third time that Tet Zoo has featured a dead giraffe (for the first time go here, and for the second go here). It's not that I don't like giraffes - quite the contrary - it's just that anything and everything about them is fascinating. Lions Panthera leo are incredibly adaptable, and seem not only to develop special techniques that allow them to successfully tackle such formidable prey, but also to take advantage of special conditions that put the prey at a disadvantage. It is widely reported that lions have learnt that giraffes are disadvantaged when forced onto paved roads: they apparently run slower, get less traction, and are hence easier to bring down. So in Kruger National Park and elsewhere, lions have been seen killing giraffes on roads again and again and again...

NOAA's Conrad Lautenbacher describes it as 'science without borders': Scientists around the world are converging data on health, weather, behavior, and disasters to anticipate illness and prepare for pandemics.
It's called the Global Earth Observation System of Systems, recognizing that patterns and behaviors all about planet earth are intimately connected. Man-made delineations aside, we truly are One World and I'm encouraged that 73 countries and more than 50 international organizations have joined so far:
WASHINGTON (AP) -- A cyclone wrecks coastal Myanmar, spawning outbreaks of malaria, cholera and dengue fever. Flooding inundates Iowa, raising an array of public health concerns. As these disasters draw attention to weather hazards, which many fear could be exacerbated by climate change, scientists are working to be able to better predict health dangers as they forecast the weather.

/////////////////////Object permanenceObject permanence is the understanding that objects continue to exist even when we can't actually see them. Famous Swiss psychologist Jean Piaget thought that children couldn't properly grasp this concept until they were at least 12 months of age.This idea was challenged by a series of studies carried out by Professor Renee Baillargeon from the University of Illinois and colleagues. These studies used children's apparent surprise at 'impossible' events to try and work out whether they understood object permanence.
A blocked roadIn one study infants as young as 6.5 months watched a toy car travelling down a ramp. Half way through its journey, though, it went behind a screen out of the baby's view before exiting the other side, once more visible. In one condition the infants saw a block placed behind the screen in the way of the toy car. And yet when the car was released, experimental trickery was used so that the block didn't stop the car's progress. Miraculously it still appeared from the other side of the screen.This 'impossible' condition was compared with another condition where the block was placed near, but not in the way of, the car's progress - the 'possible' condition.Baillargeon found that the infants looked reliably longer at the seemingly impossible scenario. This suggested they understood that the block continued to exist despite the fact they couldn't actually see it. They also must have understood that the car could not pass through the block. This seems like reasonable evidence that infants can understand object permanence.

///////////////////Vitamin D to Prevent Heart AttacksMen who are deficient in vitamin D appear to have a higher risk of heart attacks than men whose blood levels of “D” are adequate. These findings come from a review of medical records and blood samples of 454 men between the ages of 40 and 75 who had fatal or nonfatal heart attacks between January 1993 and January 2004 compared with 900 men who had no history of cardiovascular disease.
//////////////////It's strange. Isn't it?We get what we want and then feel we don't really have what we need.Many a times we are not able to differentiate between our needs and wants.We get lost in the race.We quickly forget what we have and start worrying about what we don't have.Probably this is life. We just have to carry on making the best of what we have.
