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.
Researchers have moved one step closer to a gene therapy that could silence the faulty SOD1 gene responsible for triggering a form of motor neuron disease also known as amyotrophic lateral sclerosis (ALS).
A Mississippi girl born with the AIDS virus and in remission for years despite stopping treatment now shows signs that she still harbors HIV — and therefore is not cured.
Scientists have discovered that measles and Nipah viruses manipulate the phosphorylation state of the immune sensor MDA5, keeping it inactive while the virus enters cells and replicates.
Bowel cancer patients with high levels of vitamin D in their blood are more likely to survive the disease, a new study shows. Patients with the highest levels of vitamin D have half the risk of dying compared with those with the lowest levels, the findings reveal.
It may smell awful and have a reputation for being highly toxic, but when used in the right tiny dosage, hydrogen sulfide is now being found to offer potential health benefits in a range of issues, from diabetes to stroke, heart attacks and dementia.
In an era of increasing concern about the prevalence of antibiotic-resistant illness, researchers have identified a promising new pathway to disabling disease: blocking bacteria’s access to iron in the body.
Scientists have proven that using gene-editing techniques on stem cells doesn't increase the overall occurrence of mutations in the cells.
Researchers have identified novel mutations in a well-known cancer-causing pathway in lung adenocarcinoma, the most common subtype of lung cancer. Knowledge of these genomic changes may expand the number of possible therapeutic targets for this disease and potentially identify a greater number of patients with treatable mutations because many potent cancer drugs that target these mutations already exist.
As climate change shifts the geographic ranges in which animals can be found, concern mounts over the effect it has on their parasites. Does an increased range for a host mean new territory for its parasites as well? Not necessarily, says a team of UC Santa Barbara scientists.
Bacterial infections usually announce themselves with pain and fever but often can be defeated with antibiotics—and then there are those that are sneaky and hard to beat. Now, scientists have built a new weapon against such pathogens in the form of tiny DNA pyramids. Their study found the nanopyramids can flag bacteria and kill more of them than medicine alone.
Adults with extreme obesity have increased risks of dying at a young age from cancer and many other causes including heart disease, stroke, diabetes, and kidney and liver diseases, according to results of a new analysis.
