Bumblebees copy one another when contending with unfamiliar flowers

...n individual initiative. It's not yet possible to say why bumblebees visit flowers that other bees are foraging on, but it could be that bees learn that the presence of another bee provides an efficient shortcut to success. These findings provide an intriguing new contribution to the ever-growing stack ...

FSU scientist warns North Atlantic right whale facing extinction

Scientists track stealth DNA elements in primate evolution

... be simply lying dormant. Instead, the researchers say that these elements have played a crucial role in human evolution by surreptitiously spawning hyperactive progeny copies, giving rise to the most abundant family of DNA elements in the human genome: Alu elements. The study, which was led by LSU scien...

Deep sleep short-circuits brain's grid of connectivity

Scientists have long known that the brain remains active while we sleep," Tononi says. "So what could be responsible?" To explore the breakdown of consciousness during slee...

Thinking the pain away? Study shows the brain's painkillers may cause 'placebo effect'

...ebo effect. It may help explain why so many people say they get relief from therapies and remedies with no actual physical benefit. And, it may lead to better use of cognitive, or psychological, therapy for people with chronic pain. The results will be published in the August 24 issue of the Journal of ...

Micro-molecule plays big role in birth defects

"We looked at limb development because it's a great place to demonstrate the techni...

Study casts doubt on 'Snowball Earth' theory

... the glaciation. "Snowball Earth" proponents, who say that Earth's oceans were covered by thick ice, explain the survival of life by hypothesizing the existence of small warm spots, or refugia. On the other side are supporters of a "Slushball Earth" that would have included large areas of thin ice or o...

Although the term is used frequently to describe immature cells that are the building blocks of bones, skin, flesh and organs, the actual stem cell as it exists in the brain has been enigmatic, according to Dennis Steindler, Ph.D., execu...

Expanding forests darken the outlook for butterflies, study shows

Chemical 'band-aid' prevents heart failure in mice with muscular dystrophy
