Stem cells transplanted into the brains of mice generate more numerous and more mature nerve cells if the brain cells called astrocytes are not activated. This discovery at the Sahlgrenska Academy is…

The discovery that eukaryotes, bacteria, and archaea coexisted 2.7 billion years ago came from chemical examination of shale samples, loaded with oily lipid remains of archaea found in a deep…

Scientists know that information travels between brain cells along hairlike extensions called axons. For the first time, researchers have found that axons don’t just transmit information – they can…

The Regea Institute for Regenerative Medicine, which operates under the University of Tampere in Finland, administered the first clinical stem cell therapy to two patients in cooperation with the…

The Internet is serving as a fertile medium for "HIV denialists" to spread false ideas about HIV/AIDS, which could have terrible public health consequences, say scientists in a policy paper in PLoS…

A team has examined over 300,000 genetic markers in thousands of asthmatic children and compared their data with those of healthy controls. The newly found gene, ORMDL3, is a promising object of…

By creating "Teflon" versions of natural antibiotics found in frog skin, a research team led by biological chemist E. Neil Marsh has made the potential drugs better at thwarting bacterial defenses,…

Non-medicinal interventions are highly effective in preventing the behavioral and academic problems associated with Attention Deficit Hyperactivity Disorder (ADHD), according to a five-year study led…

Research can often be a thankless job for the researcher - logically even more so if you make your data available to the community at large. Someone in the peer community will challenge it, bloggers…

We had our first SciFoo Lives On session today on Nature Island (Second Nature) in Second Life. We had about a dozen people participate. The topic was "Tools for Open Science". I wanted to explore…

Researchers at Pacific Northwest National Laboratory are uniting theory, computation and experiment to discover exactly how heavy elements, such as uranium and technetium, interact in their…

Errors in the genetic code can give rise to cancer and a host of other diseases, but finding these errors can be more difficult than looking for the proverbial needle in the haystack. Now, scientists…

Do bats use their ultrasonic echolocation calls to recognize their own species? A new study in the Journal of Biogeography by Danilo Russo and colleagues suggests that this is certainly the case for…

Scientists at Pacific Northwest National Laboratory have discovered a way to increase the sensitivity of test strips that will enable creation of a portable biosensor that can address a major concern…

Combine a mechanical arm with a miniature rocket motor: The result is a prosthetic device that is the closest thing yet to a bionic arm. A prototype of this radical design has been successfully…

Without the heartbreak of ended relationships, half of popular music would cease to exist. Everyone has had one but it turns out it probably wasn't so bad - especially if you thought it would be…

In 17th century Rome, the Baroque painter Orazio Gentileschi gave all his children the finest art education available. But only one of them—his daughter Artemisia—developed into an artist. In fact,…

Chemical engineers at Purdue believe they have discovered a fundamental flaw in the conventional view of how liquids form bubbles that grow and turn into vapors and that their findings cast into…

Dozens of scientists from several countries gathered at the University of Alaska Fairbanks to discuss the latest findings on noctilucent clouds and other phenomena of the earth’s upper atmosphere…

Yes, your favorite color is blue. Most of you, anyway. Except some women, who go for the redder part of the red-green axis. A lot of science sites got a press release from Current Biology and went…
