Study: Bees Have Distinct Personalities

"Some bees are thrill-seekers while others prefer to hang around the hive, according to new research published in the journal Science. The study shows that some honey bees are more eager to take on certain jobs than their comrades. And researchers say this could be down to differences in their personalities."

Scientists Use Stem Cells to Generate Human Eggs

"Researchers at Massachusetts General Hospital say they have extracted stem cells from human ovaries and made them generate egg cells. The advance, if confirmed, might provide a new source of eggs for treating infertility, though scientists say it is far too early to tell if the work holds such promise."

Science Overturns View of Humans as Naturally 'Nasty'

"Biological research increasingly debunks the view of humanity as competitive, aggressive and brutish, a leading specialist in primate behavior told a major science conference Monday."

Humans Have About 100 Broken Genes Each

"A new analysis of 185 human genomes indicates that every one of us has about 100 'broken genes.' Some of these lost genes cause harmful effects, many seem innocuous, and some even seem to have some benefit."

Skin Transformed Into Brain Cells

"Skin cells have been converted directly into cells which develop into the main components of the brain, by researchers in California."

What the Top 1% of Earners Majored In

"According to the Census Bureau’s 2010 American Community Survey, the majors that give you the best chance of reaching the 1 percent are pre-med, economics, biochemistry, zoology and, yes, biology, in that order."

Study Finds No Better Odds Using 3 Embryos in IVF

"A new study of fertility treatment found that women who get three or more embryos have no better odds of having a baby than those who get just two embryos."

Mental Sharpness Begins to Decline in Middle-Age

"The brain's abilities to reason, comprehend and remember may start to worsen as early as age 45, a new study from England suggests."

“Super Memory” Pill–and Possibly an Alzheimer’s Cure–Could Be Around the Corne'

"Scientists have isolated a gene in mice that works to give them "super memories' and reverses the course of several degenerative mental illnesses like Alzheimer's. And because of the similarity of mice and human brains, a powerful brain pill for humans may now not be far off."

Pair of NASA Studies Reaffirm Impact of Global Warming

"NASA officials have released a pair of new studies showing that global warming could lead to a major transformation for Earth's plants and animals over the next century."

Report: Millions of Birds Killed By Power Lines

"Tens of millions of flamingos, storks, pelicans and other migratory birds are being killed across the world when they fly into power lines, according to a new study."

Aging Brains Use Extra Regions to Shore Up Eroding Abilities

"Though it may lose some abilities, the older brain compensates by bringing alternate circuits to bear, say several reports from the Society for Neuroscience meeting."

Trees Not Adapting Well to Climate Change

"More than half of tree species in eastern U.S. forests aren't adapting to climate change as quickly or consistently as predicted, researchers said."

Discovery May Help Produce Stem Cells

"A new way to rejuvenate old stem cells raises the possibility that patients' own stem cells may one day be rescued and banked, U.S. researchers say."

Motherhood Changes Brain Function

"Motherhood is associated with a host of new behaviors that are driven, at least in part, by alterations in brain function, researchers in Israel say."

Climate Change Spawns the Incredible Shrinking Ant

"Plants and animals are shrinking because of warmer temperatures and lack of water, researchers said on Monday, warning it could have profound implications for food production in years ahead."

Study: Worms Show Extinction Recovery

"After a global extinction 65 million years ago that wiped out much of life on Earth, lowly worms were likely the first life to re-emerge, U.S. researchers say."

Study: Great Lakes' Mercury Pollution Poses Health Risks

"Mercury pollution in the Great Lakes region is much greater than previously reported, and people eating some of the fish there face potential health risks, a new report concludes."

Thin Moms And Dads Pass On 'Skinny Genes'

"Like mother, like daughter? Turns out, the "inter-generational transmission of thinness" is real. Parental weight strongly influences slimness in children, a study of 7,000 families finds."

Scientists Use Cloning to Make Human Stem Cells

"U.S. scientists for the first time have used a cloning technique to get tailor-made embryonic stem cells to grow in unfertilized human egg cells, a landmark finding and a potential new flashpoint for opponents of stem cell research."
