Researchers have uncovered a genetic deficiency in males that can trigger the development of one of the most common types of liver cancer and forms of diabetes.
After conducting a major review of evidence, the European Food Safety Authority has found that the artificial sweetener aspartame is safe for people to consume at the levels currently used in diet soft drinks.
Harmless lung cancer? A provocative study found that nearly 1 in 5 lung tumors detected on CT scans are probably so slow-growing that they would never cause problems.
A new microchip-based device may greatly simplify the monitoring of patients’ response to treatment for ovarian cancer— the most lethal form of gynecologic cancer— and certain other malignancies.
There is more than meets the eye following even a mild traumatic brain injury. While the brain may appear to be intact, new findings report that the brain’s protective coverings may feel the brunt of the impact.
New demographic data on humans, animals and plants for the first time unveils such an extraordinary diversity of aging processes that no existing evolutionary theory can account for it.
A new research program will investigate the relationship between exposure to environmental tobacco smoke during pregnancy and childhood and attention deficit hyperactivity disorder (ADHD) in children.
Yes, our prehistoric ancestors had to fend off saber-toothed cats and gigantic hyenas. But did they ever have to take an organic chemistry final or host the in-laws for the holidays? Now that’s stress. And what we eat can either help our bodies fight stress– or hurt the effort.
In one of the biggest advances against leukemia and other blood cancers in many years, doctors are reporting unprecedented success by using gene therapy to transform patients' blood cells into soldiers that seek and destroy cancer.
While posttraumatic stress is expected after natural disasters, few survivors anticipate the positive psychological changes that they may experience – and now new research has revealed that genes may play a role.
A new study shows out that mice with a mutation in the gene for the protease Tmprss2 do not become infected by flu viruses containing hemagglutinin type H1.
Men who continued to smoke after a cancer diagnosis had an increased risk of death compared with those who quit smoking after diagnosis, according to a new study.
The herpes virus that produces cold sores during times of stress now has been linked to cognitive impairment throughout life, according to a new study.
In search of better cancer treatments, researchers have designed synthetic molecules that combine the advantages of two experimental RNA therapies.
Scientists have found that cells known primarily for tempering immune response also exist in injured muscle tissue, an unexpected role for regulatory T cells.
A new study reports that the brain can produce and release estrogen— a discovery that may lead to a better understanding of hormonal changes observed from before birth throughout the entire aging process.
The most active component of grape seed extract, B2G2, induces the cell death known as apoptosis in prostate cancer cells while leaving healthy cells unharmed, according to a new study.
Researchers have discovered the first evidence that the nerves in the stomach act as a circadian clock, limiting food intake to specific times of the day.
As you step outdoors into the bright sunshine, your pupils automatically contract. Scientists are making use of how this "pupil reflex" is connected to the brain as a potential new way of testing the severity of multiple sclerosis (MS).
Coffee and beer are polar opposites in the beverage world. Coffee picks you up, and beer winds you down. Now, researchers have discovered that the beverages may also have opposite effects on your genome.
Researchers are investigating a potential new therapy for autism and other neurodevelopmental disorders by treating gut microbiota with probiotic therapy, which influences autism-like behaviors in a mouse model.
A new report has revealed that the number of people living with dementia worldwide in 2013 is now estimated at 44 million, reaching 76 million in 2030 and 135 million by 2050.
Triplets-and-more increasingly are the result of drugs given to women to make them produce eggs — not from using multiple embryos from IVF, or lab-dish fertilization, new research shows.
A new approach developed by researchers could enable the most detailed x-ray images ever— including clear views of soft tissue without any need for contrast agents.
Scientists have identified an enzyme that can halt or possibly even reverse the build-up of toxic protein fragments known as plaques in the brains of mice with Alzheimer’s disease.
