REST molecule acts as an adapter in stem cells, times neuronal development

Upon fertilisation, a single cell is formed when egg and sperm fuse. Our entire body, with more than 200 specialised cell types and billions of cells are formed from this single cell. It is a scientific mystery how the early stem cells know what cell type to become, but a precise timing of the process is crucial for correct development and function of our body.

Longer looks: Romney's evolution on abortion; The birth of the HIV epidemic

GOP presidential candidate Mitt Romney began his political career as a pro-choicer. In the story he tells, he had an epiphany, a flash of insight, and committed himself thereafter to protecting life. But that isn't what happened. The real story of Romney's conversion-;a series of tentative, equivocal, and confused shifts, accompanied by a constant rewriting of his past-;paints a more accurate picture of who he is.

Four leading organizations release recommendations to ensure optimal care of TAVR patients

Four leading heart organizations representing cardiologists and cardiothoracic surgeons released initial recommendations today for creating and maintaining transcatheter aortic valve replacement (TAVR) programs.

Researchers observe how cholera decimates competing bacteria and human cells

Bacteria live in a state of perpetual warfare, with different species battling for dominion over their competitors and when pathogen, over their infected host. New research suggests that the human pathogen Vibrio cholerae, which causes the disease cholera, kills off its microbial rivals by jabbing them with a spring-loaded poison dagger.

TMED7 protein can shut down immune system after infection has been cleared

Scientists from Trinity College Dublin have discovered a new 'off switch' in our immune response which could be boosted in diseases caused by over-activation of our immune system, or blocked to improve vaccines.

Genome sequencing helps characterize S. aureus ST398-NM strain

Using genome sequencing and household surveillance, National Institutes of Health (NIH) scientists and their colleagues from Columbia University Medical Center and St. George's University of London have pieced together how a newly emerging type of Staphylococcus aureus bacteria has adapted to transmit more easily among humans.

Researchers discover connection between early humans and Neanderthals' genome

A striking discovery in the study of human genetics was the focus of the most-visited press release posted on EurekAlert! in 2011. Researchers found that part of the non-African human X chromosome came from Neanderthals, confirming that they interbred with early human populations.

Cross-protective vaccines will make a bout with influenza less severe

An emerging class of long-lasting flu vaccines could do more than just save people the trouble of an annual flu shot.

Evolutionary forces encourage diversity in the active surfaces of venomous toxins

For snakes, spiders, and other venomous creatures, the "business end," or active part, of a toxin is the area on the surface of a protein that is most likely to undergo rapid evolution in response to environmental constraints, say researchers from Ben Gurion University in Israel.

UA researchers identify the likely culprit of epilepsy

Only 10 years ago, deciphering the genetic information from one individual in a matter of weeks to find a certain disease-causing genetic mutation would have been written off as science fiction. It was the time of the Human Genome Project, and it had taken armies of sequencing robots working around the clock for almost a decade to unravel the complete sequence of the human genetic code - referred to as the genome - by churning out the DNA alphabet letter by letter.

MRSA strain in food animals concerns experts

The strain of staph, known as methicillin-resistant Staphylococcus aureus, or MRSA CC398, most often infects farm workers who come in contact with infected pigs, turkeys, or cows. Now the strain of bacteria has been found in about half of meat samples taken throughout the country. The researchers say that the indiscriminate use of antibiotics in livestock used for food is to blame for the infection's drug resistance.

Eating invasive plant pre-adapts bluetongue lizards against cane toad poisons

An invasive plant may have saved an iconic Australian lizard species from death at the hands of toxic cane toads, according to research published in the March issue of The American Naturalist. It's an interesting case of one invasive species preparing local predators for the arrival of another, says Richard Shine, a biologist at the University of Sydney who led the research.

New kind of on-off switch for cortisol release in the brain discovered

After we sense a threat, our brain center responsible for responding goes into gear, setting off a chain of biochemical reactions leading to the release of cortisol from the adrenal glands.

SOT 51st Annual Meeting and ToxExpo to be held March 11-15

The Society of Toxicology (SOT) 51st Annual Meeting and ToxExpo - the largest meeting and expo of its kind anywhere in the world - will take place from March 11-15. The five-day program will feature more than 180 sessions, presenting the latest research findings and recommendations for remedial action on a wide range of issues affecting human and animal health and the environment.
