Genetic Divergence Of Man From Chimp Has Aided Human Fertility But Cou
The one percent of the human and chimpanzee genomes that differ from each other reveal how evolution has individually shaped the two species' genes since sharing a common ancestor five million years ago, according to a study led by Cornell University researchers Rasmus Nielsen, Andrew Clark and Carlos Bustamante. Cell Mutations That Lead To Apoptosis May Contribute To Aging In Mamma
A University of Florida study has found that mutations in the mitochondria caused by obesity and lack of exercise -- not oxidative stress from free radicals -- may be a key factor in the aging process. Study Finds Enzyme Activity Promotes Rare Form Of Leukemia, Offers Pot
Scientists at the University of North Carolina at Chapel Hill have identified an enzyme that helps trigger the development of leukemia, a cancer of blood cells. Eat Less To Live Longer: Calorie Restriction Linked To Long Healthy Li
For nearly 70 years scientists have known that caloric restriction prolongs life. In everything from yeast to primates, a significant decrease in calories can extend lifespan by as much as one-third. But getting under the hood of the molecular machinery that drives this longevity has remained elusive. Researchers have now discovered two genes in mammalian cells that act as gatekeepers for cellular longevity. When cells experience certain kinds of stress, such as caloric restriction, these genes rev up and help protect cells from diseases of aging. Astronomers Use Laser To Take Clearest Images Of The Center Of The Mil
UCLA astronomers and colleagues have taken the first clear picture of the center of our Milky Way galaxy, including the area surrounding the supermassive black hole, using a new laser virtual star at the W.M. Keck observatory in Hawaii. "Everything is much clearer now,"said Andrea Ghez, UCLA professor of physics and astronomy, who headed the research team. "We used a laser to improve the telescope's vision -- a spectacular breakthrough that will help us understand the black hole's environment and physics. It's like getting Lasik surgery for the eyes, and will revolutionize what we can do in astronomy." Unravelling The Secrets Of Cancer Cells
New cancer models could lead to a greater understanding of the triggers that affect cancer cells. Scientists have developed a 3-D model of the mammary gland which allows them to study how cells can organize to form tissues and how cancer cells become normal again. New Method For Detecting Fake Drugs Without Opening The Package
With sale of counterfeit drugs causing major problems around the world, scientists in the United Kingdom are reporting development of a new way of identifying fake pills and capsules without opening the product package. In a report scheduled for the March 1 issue of ACS' Analytical Chemistry, a semi-monthly journal, Pavel Matousek and Charlotte Eliasson describe the growing need for non-invasive verification of the authenticity of pharmaceutical products. [Funny] A referee has sent himself off in an English amateur league ma
Andy Wain had to abandon the Sunday league match between Peterborough North End and a Royal Mail side in the 63rd minute after throwing down his whistle and marching up to confront North End's keeper. Apple Settles IPod Batteries Suit
Poorly performing power sources may spell a massive payout for the computer company: Nearly 2 million people with older iPods could get $50 coupons and extended warranties. Palaeography: Reading Old Handwriting, 1500-1800: A Practical Online T
"Palaeography is the study of old handwriting. This web tutorial will help you learn to read the handwriting found in documents written in English between 1500 and 1800."Practice documents include wills, petitions, estate inventories, and fun material such as "Recipe for mince pies. Early 17th century."From the National Archives (Surrey, United Kingdom) in partnership with University College London.
