Women Should Be Advised Not To Drink Alcohol In Pregnancy
Expectant mothers should be advised not to drink alcohol, as this may pose health risks to the foetus, argues an editorial in this week's BMJ. Heads Or Tails? Scientists Identify Gene That Regulates Polarity In Re
When cut, a planarian flatworm can use a population of stem cells called neoblasts to regenerate new heads, new tails or even entire new organisms from a tiny fragment of its body. Mechanisms have been sought to explain this process of regeneration polarity for over 100 years, but until now, little was known about how planaria can regenerate heads and tails at their proper sites. The gene Smed-beta-catenin-1 has now been discovered to regulate polarity in regenerating flatworms. New Way To Identify, Evolve Novel Enzymes
The creation of totally new enzymes can help improve the synthesis of chemicals and pharmaceuticals, devise new tools for molecular biology research, and develop new therapies. The new way of creating novel enzymes does not require prior understanding of exactly how the enzymes work. This is the first technique that does not depend on prior knowledge of enzyme's mechanism. Restoration Of A Habitat-forming Species Could Nurture The Return Of M
Coral reefs, kelp forests, marshes and other familiar habitats can harbor a diversity of life by providing shelter from both harsh conditions and predators. New experimental work using cordgrass habitats suggests those positive effects of living habitats are the most important factor in driving the diversity and abundance of organisms in many ecosystems. The researchers suggest that facilitation cascades could be tapped to aid conservation efforts. Killer Radio Contest: The Tape
Sacramento morning hosts running a "Hold Your Wee for a Wii" contest didn't stop a woman from apparently drinking herself to death. YouTube has the audio. In Bodyhack. [Ironic] LONDON: A jailed cocaine dealer is working as Santa Claus on
John Tams, who dons beard, boots and red suit to work in a cafe's Christmas grotto, said he wanted to give something back to the community... Rants 'n' Raves: Solo Nuke Hunt
Readers assert that the DIY nuke detector works independently, lament fear of terrorism and insist that some Indians buy gadgets in the legal market. [Ironic] Professional beggars prowling about the streets of Moroccan c
The government plans to crack down on the scam used by faux beggars in growing numbers for a kind of "emotional blackmail", a cabinet minister was quoted as saying... Biblical Latrine: Ancient Parasites Show That Cleanliness May Have Bee
Those who make a great show of being religiously pure often lead lives that are secretly very dirty -- or at least so it was in biblical times. Recent bioarchaeological findings at the ancient Dead Sea settlement of Qumran confirm the existence of a strange communal latrine -- located at a remote distance, conforming with extreme hygiene practices described in ancient texts and possibly accounting for a documented early mortality rate at the settlement. New Genetic Model For Parkinson's Disease
Researchers at the Karolinska Institute in Sweden are homing in on mechanisms that may explain one set of causes for Parkinson's disease. In mice they have mimicked disturbances of mitochondria thought to be one cause of disease. By genetic means the disturbance of mitochondria -- the energy factories of cells -- were directed to those nerve cells that produce thetransmitter substance dopamine and that die in Parkinson's diseases.
