Biologists from Indiana University and Montana State University have discovered a striking connection between viruses such as HIV and Ebola and viruses that infect organisms called archaea that grow in volcanic hot springs. Despite the huge difference in environments and a two billion year...

Although scientists have known since the middle of the 19th century that the tropics are teeming with species while the poles harbor relatively few, the origin of the most dramatic and pervasive biodiversity on Earth has never been clear. New research sheds light on how that pattern came about....

Researchers from the University of Tokushima in Japan have published in the June issue of Epigenetics a study that suggests that homocysteine (one of the building blocks of proteins) plays a role in the pathogenesis of schizophrenia via an epigenetic mechanism that controls the expression of genes....

It's not going to happen while you're peering through your binoculars, but African glossy starlings change color more than 10 times faster than their ancestors and even their modern relatives, say researchers at The University of Akron and Columbia University. The changes have led to new species of...

New research reveals that transplantation of partial livers from deceased adult and teen donors has become less risky for infants and young children, helping to save these young lives. Findings published online in Liver Transplantation, a journal of the American Association for the Study of Liver...

Just a few years ago, integrated positron emission tomography and magnetic resonance (PET/MR) imaging was found only in research institutes, but little by little the technology has expanded into clinical practice. This is especially true for cardiac indications, for which the highly sensitive soft...

Taking pictures of individual atoms allows scientists at the Vienna University of Technology to find out how catalysts behave and how atoms on a surface tend to ball together. For the first time, this clustering effect can be directly observed. In catalysts, this effect is a serious problem: Once the atoms cluster, they are not...

They may volunteer to be the one to get their friends home safely, but "designated drivers" often drink -- even to a level that impairs them behind the wheel, according to a report in the July issue of the Journal of Studies on Alcohol and Drugs. Fuente :...

A new study has found that women can be screened for colorectal cancer at least five to 10 years later than men when undergoing an initial "virtual colonoscopy." Published early online in CANCER, a peer-reviewed journal of the American Cancer Society, the findings may help establish guidelines for...

Maybe better call that cab, after all: a new University of Florida study found that 35 percent of designated drivers had quaffed alcohol and most had blood-alcohol levels high enough to impair their driving. Fuente : http://www.eurekalert.org/pub_releases/2013-06/uof...

Scientists have deciphered how a protein called Arc regulates the activity of neurons -- providing much-needed clues into the brain's ability to form long-lasting memories. These findings also offer newfound understanding as to what goes on at the molecular level when this process becomes...

Researchers have developed a new technique for measuring very weak forces on a molecular scale. Thanks to the use of carbon nanotubes, they have achieved the highest level of sensitivity to date. These results open the door for magnetic resonance imaging of individual molecules. Fuente :...

The duck genome consortium has completed the genome sequencing and analysis of the duck (Anas platyrhynchos), one principal natural host of influenza A viruses, which caused a new epidemic in China since this February. This work reveals some noteworthy conclusions and provides an invaluable...
