Most of the genetic risk for autism comes from versions of genes that are common in the population rather than from rare variants or spontaneous glitches, researchers have found. Heritability also outweighed other risk factors in this largest study of its kind to date.
A research team has demonstrated that the viral reservoir of HIV-1 infection is established strikingly early after intrarectal simian immunodeficiency virus (SIV) infection of rhesus monkeys and before detectable viremia.
New research provides an intriguing glimpse into the processes that establish connections between nerve cells in the brain. These synapses allow nerve cells to transmit and process information involved in thinking and moving the body.
A cross-disciplinary team is calling for public discussion about a potential new way to solve longstanding global ecological problems by using an emerging technology called “gene drives.” The advance could potentially lead to powerful new ways of combating malaria and other insect-borne diseases.
A daily low-dose aspirin is widely prescribed for the prevention of cardiovascular disease. Now, a new study suggests that common genetic variation may modify the cardiovascular benefit of aspirin.
Researchers have uncovered a genetic vulnerability of cancer cells that express telomerase— an enzyme that drives their unchecked growth— and showed that telomerase-expressing cells depend upon a gene named p21 for their survival.
In mice with diet-induced diabetes, the equivalent of type 2 diabetes in humans, a single injection of the protein FGF1 is enough to restore blood sugar levels to a healthy range for more than two days, according to a new study.
The largest study of the effects of the main ingredient of cannabis has shown definitively that it can cause short-term paranoia. The research also, for the first time, identifies psychological factors that can lead to feelings of paranoia in people who take cannabis.
Scientists may be able to entomb the malaria parasite in a prison of its own making, researchers at are reporting. The malaria parasite is among the world’s deadliest pathogens.
Popping the blisters on the bubble wrap might be the most enjoyable thing about moving. But now, scientists propose a more productive way to reuse the popular packing material—as a sheet of small, test tube-like containers for medical and environmental samples.
Taking B vitamins doesn't slow mental decline as we age, nor is it likely to prevent Alzheimer's disease, conclude researchers who have assembled all the best clinical trial data involving 22,000 people to offer a final answer on this debate.
Brain stimulation used to be just a cool idea in science fiction movies, novels and other hard to believe tales when human subjects were stimulated using electrical currents and achieved near super-human feats. Now, brain stimulation is a step closer to becoming a possible reality.
When it comes to infecting humans and animals, bacteria need a helping hand. Biochemists have found the helping hand: groups of tiny protein loops on the surface of cells.
Neuroscientists have generated mutant worms that do not get intoxicated by alcohol, a result that could lead to new drugs to treat the symptoms of people going through alcohol withdrawal.
Scientists have linked a new protein to Alzheimer's disease, different from the amyloid and tau that make up the sticky brain plaques and tangles long known to be its hallmarks.
What we currently know about aging is not highly specific; our cells divide many times throughout our lives and eventually cause organs and our bodies to age, break down and fail. New research, however, suggests that how we age might depend on cellular interactions that we inherit from our ancestors, accumulating throughout many generations.
New research has identified, for the first time, the structural damage at a molecular level that excessive alcohol abuse causes to the brain. The study detected the loss and modification of several key cellular proteins in the brains of alcoholics.
Two years ago, the exceptional creativity of Parkinson's patients was demonstrated in a review for Behavioral Neuroscience. Now, a new empirical study definitively demonstrates that Parkinson's patients are more creative than their healthy peers.
A third of Alzheimer’s disease cases worldwide can be attributed to risk factors that can be potentially modified, such as lack of education and physical inactivity, according to new research.
Being sick due to an infection can make us feel lousy. But what must the ecosystem of bacteria, or microbiota, colonizing our guts be going through when hit with infection? A new study has utilized unique computational models to show how infection can affect bacteria that naturally live in our intestines.
A new fruit that research says packs more antioxidants than popular "superfoods" like blueberries, acai berries and goji berries is establishing itself in the aisles of mainstream grocery stores, showing up in everything from juices to powdered supplements to baby food.
Unexplained rash? Check your iPad. It turns out the popular tablet computer may contain nickel, one of the most common allergy-inducing metals. Recent reports in medical journals detail nickel allergies from a variety of personal electronic devices, including laptops and cellphones.
As daily temperatures increase, so does the number of patients seeking treatment for kidney stones. In a study that may both reflect and foretell a warming planet’s impact on human health, a research team found a link between hot days and kidney stones in 60,000 patients in several U.S. cities with varying climates.
Mice consuming a supplement of omega 3 fatty acids had healthier joints than those fed diets high in saturated fats and omega 6 fatty acids, according to researchers.
