The Ebola virus remains viable for at least seven days after death in non-human primates. A new study, published in Emerging Infectious Diseases, suggests that Ebola transmission from deceased individuals may be possible for an extended period of time after death, underscoring the importance of using safe practices for handling corpses.
Beavers don’t brush their teeth, and they don’t drink fluoridated water, but a new study reports beavers do have protection against tooth decay built into the chemical structure of their teeth.
This winter's nasty flu season has peaked and is clearly retreating, a new government report shows.
The Human Genome Project wrapped up over a decade ago, yet around a third of the genome remains mysterious, its function unknown.
Engaging in unprotected sex with multiple partners increases the risk of contracting multiple strains of HIV, the virus that causes AIDS. Once inside a host, these strains can recombine into a new variant of the virus.
Receiving the human papillomavirus vaccine does not increase rates of sexually transmitted infections (STIs) in adolescent females. The vaccine, which can prevent cervical cancer in women, has had a low uptake, partly because of concerns about how it will affect adolescent sexual activity.
Although wearable devices have received significant attention for their ability to track an individual’s physical activity, most smartphone applications are just as accurate, according to a new research letter in JAMA.
Stroke experts are reporting a major advance: Stents similar to the ones used to open clogged heart arteries also can be used to clear a blood clot in the brain, greatly lowering the risk a patient will end up disabled.
High systolic blood pressure – the top number in a blood pressure reading – has long been considered an indicator of cardiovascular disease risk for adults over 50. But now a new Northwestern Medicine study suggests that it’s also important for younger adults.
Stating that sleep is an essential biological process seems as obvious as saying that the sun rises every morning. Yet, researchers' understanding of the molecular mechanisms underlying the effects of sleep loss is still in its earliest stages.
Damage to the brain's outer layer caused by smoking may be reversible after quitting, but it could take years, a study said. Brain scans of 500 Scottish septuagenarians confirmed a link between smoking and an acceleration of age-related thinning of the cortex—the outer layer of grey matter, researchers reported.
Scientists at The Scripps Research Institute (TSRI) have identified a new cellular pathway that is affected in cystinosis, a rare genetic disorder that can result in eye and kidney damage.
The researchers, from Cancer Research UK's Health Behaviour Research Centre at University College London (UCL), interviewed almost 1,900 people aged 50-80 years old about their views on cancer screening.
A vial of rare snake venom refused to give up its secret formula for lethality; its toxins had no effect on the proteins that most venoms target.
Firsthand experience working in hospitals and clinics helped inspire third-year Stanford medical student Pelu Tran to explore a potential career path in the world of high-tech startups.
Ebola has claimed nearly 9,000 lives in West Africa over the past year, although new infections have dropped dramatically in recent months.
President Barack Obama's nominee to serve as U.S. drug "czar" won unanimous approval in the Senate Monday as lawmakers vowed to curb an epidemic that results in more than 40,000 deaths a year from overdoses of prescription painkillers, heroin and other substances.
Researchers have revealed how damage from obesity is passed from a mother to her children, and also how that damage can be reversed.
After the highly charged Super Bowl, two sobering studies emerged. One unveiled an improved molecular imaging technology that verified—and precisely identified—brain damage in some National Football League (NFL) players. The other study revealed that brain damage can be more severe in NFL players who start playing football before age 12.
Scientists have developed a potential new therapy based on an unlikely model: immune molecules from cows.
A new Dartmouth College study sheds light on the brain cells that function in establishing one's location and direction. The findings contribute to our understanding of the neural mechanisms underlying our abilities to successfully navigate our environment, which may be crucial to dealing with brain damage due to trauma or a stroke and the onset of diseases such as Alzheimer's.
Have you ever wondered why it’s so tough to put down that last slice of bacon? Part of the answer is that humans are evolutionarily programmed to crave fatty foods, which offer the biggest bang for the buck, nutritionally speaking, with more than twice the calorie density of protein- or starch-rich food.
SuperAgers, aged 80 and above, have distinctly different looking brains than those of normal older people, according to new Northwestern Medicine research that is beginning to reveal why the memories of these cognitively elite elders don’t suffer the usual ravages of time.
In the 1980s, immunotherapy researcher Lieping Chen, M.D., Ph.D., embraced the career goal of curing one cancer. That lofty-seeming goal is beginning to look more modest today. Recent clinical trials have shown that one cancer after another is vulnerable to immune modulation therapy, a cancer-fighting strategy Chen pioneered that for years was considered marginal.
In 2008, the World Health Organization announced a global effort to eradicate malaria, which kills about 800,000 people every year. As part of that goal, scientists are trying to develop new drugs that target the malaria parasite during the stage when it infects the human liver, which is crucial because some strains of malaria can lie dormant in the liver for several years before flaring up.
