MOBILES

Mobiles 'not brain cancer risk'
BBC News - 10 hours ago
Mobile phone use does not raise the risk of brain tumours, a Japanese study suggests. The research is the first to look at the effects of hand set radiation levels on different parts of the brain.

Earthtimes - 1 hour ago
Most women who opt to undergo a caesarean section are scared of labour pains and are not too snooty as assumed previously, a new study by researchers at the Karolinska Institute in Sweden has suggested.

According to a new study, the black hole's gravitational pull on the white dwarf would cause tidal forces sufficient to disrupt the stellar remnant and reignite nuclear burning in it, giving rise to a supernova explosion with an unusual appearance. ... > full story


////////////////////////////////Ancient bones suggest cavemen wore boots

Footwear , it seems, has been fashionable for rather a long time. Toe bones from a cave in China suggest people were wearing shoes at least 40,000 years ago.

Erik Trinkaus and Hong Shang, from Washington University in St Louis, Missouri, measured the shape and density of toe bones from a 40,000-year-old skeleton found in Tianyuan cave near Beijing. They compared these bones with those from 20th century urban Americans, late-prehistoric Inuits and other late-prehistoric Native Americans.

///////////////////////////////////BBC=Three-parent embryo formed in lab

The scientists have created the embryo in the lab
Scientists believe they have made a potential breakthrough in the treatment of serious disease by creating a human embryo with three separate parents.
The Newcastle University team believe the technique could help to eradicate a whole class of hereditary diseases, including some forms of epilepsy.

The embryos have been created using DNA from a man and two women in lab tests.

It could ensure women with genetic defects do not pass the diseases on to their children.

It is human beings they are experimenting with

'Our aim is to help children'

The technique is intended to help women with diseases of the mitochondria - mini organelles that are found within individual cells.

They are sometimes described as "cellular power plants" because they generate most of the cell's energy.

Faults in the mitochondrial DNA can cause around 50 known diseases, some of which lead to disability and death.

About one in every 6,500 people is affected by such conditions, which include fatal liver failure, stroke-like episodes, blindness, muscular dystrophy, diabetes and deafness.

At present, no treatment for mitochondrial diseases exists.

Genetic transplant

The Newcastle team have effectively given the embryos a mitochondria transplant.

We believe we could develop this technique and offer treatment in the forseeable future that will give families some hope of avoiding passing these diseases to their children

Professor Patrick Chinnery
University of Newcastle

They experimented on 10 severely abnormal embryos left over from traditional fertility treatment.

Within hours of their creation, the nucleus, containing DNA from the mother and father, was removed from the embryo, and implanted into a donor egg whose DNA had been largely removed.

The only genetic information remaining from the donor egg was the tiny bit that controls production of mitochondria - around 16,000 of the 3billion component parts that make up the human genome.

The embryos then began to develop normally, but were destroyed within six days.

Appearance

Experiments using mice have shown that the offspring with the new mitochondria carry no information that defines any human attributes.

So while any baby born through this method would have genetic elements from three people, the nuclear DNA that influences appearance and other characteristics would not come from the woman providing the donor egg.

However, the team only have permission to carry out the lab experiments and as yet this would not be allowed to be offered as a treatment.

Professor Patrick Chinnery, a member of the Newcastle team, said: "We believe that from this work, and work we have done on other animals that in principle we could develop this technique and offer treatment in the forseeable future that will give families some hope of avoiding passing these diseases to their children."

Dr Marita Pohlschmidt, of the Muscular Dystrophy Campaign, which has funded the Newcastle research, was confident it would lead to a badly needed breakthrough in treatment.

"Mitochondrial myopathies are a group of complex and severe diseases," she said.

"This can make it very difficult for clinicians to provide genetic counselling and give patients an accurate prognosis."

However, but the Newcastle work has attracted opposition.

Josephine Quintavalle, of the pro-life group Comment on Reproductive Ethics, said it was "risky, dangerous" and a step towards "designer babies".

"It is human beings they are experimenting with," she said.

"We should not be messing around with the building blocks of life."

Mrs Quintavalle said embryo research in the US using DNA from one man and two women was discontinued because of the "huge abnormalities" in some cases.

Dr David King, of Human Genetics Alert, expressed concern about a "drift towards GM babies".
