A massive worldwide analysis of genetic data from almost 340,000 people around the world has brought understanding of the genetic basis of obesity a step closer.
Like a stealth jet cloaks itself from radar, cancer cells cloak themselves within tumors by hiding behind a dense layer of cellular material known as stroma.
Using advanced DNA sequencing methods, researchers have identified a new gene that is associated with sporadic amyotrophic lateral sclerosis (ALS), or Lou Gehrig’s disease.
The World Health Organization said Friday it has approved a quick test for Ebola that will dramatically cut the time it takes to determine - with reasonable accuracy - whether someone is infected with the deadly virus.
More hospitals and doctors are starting to use data from fitness trackers and health apps to help treat patients. But they are moving cautiously. The technology has a lot of potential, but there are key challenges to work out...
Researchers have identified a distinctive brain signature in people with melancholic depression, supporting calls for its classification as a unique mood disorder type.
Using antibodies from camels and alpacas, scientists have found a way to deliver anticancer viruses directly to tumor cells, leaving other types of cells uninfected.
Nanometer-sized “drones” that deliver a special type of healing molecule to fat deposits in arteries could become a new way to prevent heart attacks caused by atherosclerosis.
Scientists are interested in using gels to deliver drugs because they can be molded into specific shapes and designed to release their payload over a specified time period. However, current versions aren’t always practical because must be implanted surgically.
Contaminated medical instruments are suspected in a "superbug" outbreak at a Los Angeles hospital that has infected at least seven patients, two of whom died. More than 170 others may have been exposed to the antibiotic-resistant bacteria.
A new study conducted by a researcher at the George Washington University suggests that the right hemisphere of the brain may be able to assist a damaged left hemisphere in protecting visual attention after a stroke.
The pathological process amyloidosis, in which misfolded proteins (amyloids) form insoluble fibril deposits, occurs in many diseases, including Alzheimer disease (AD) and type 2 diabetes mellitus (T2D).
Research suggests that fetal exposure to chemicals or drugs can cause neurological problems. Babies whose mothers take the epilepsy drug valporic acid (VPA) during pregnancy, for example, appear to have an elevated risk of developing an autism spectrum disorder.
Running hard may be as bad for your longevity as being a couch potato, says a recent study—one that should be taken with a grain of salt (hold the butter), say some critics. The study, in a recent Journal of the American College of Cardiology, examined 5,048 healthy people enrolled in the Copenhagen City Heart Study. For 12 years, 1,098 healthy joggers and 413 healthy, but sedentary non-joggers were followed.
This new insight about Broca’s area, which is located in the frontal cortex above and behind the left eye, could ultimately benefit the treatment of language impairments due to stroke, epilepsy and brain injuries.
Researchers have found that a compound produced by the body when dieting or fasting can block a part of the immune system involved in several inflammatory disorders such as type 2 diabetes, atherosclerosis, and Alzheimer’s disease.
There is no way to spot Alzheimer's early, no effective treatment and no known cure.
New research suggests that this bacterium causes more often causes severe sore throats in young adults than streptococcus — the cause of the much better known strep throat.
A protein has been shown to have a surprising role in regulating the 'glue' that holds heart cells together, a finding that may explain how a gene defect could cause sudden cardiac death.
Global health organizations said Tuesday that AIDS is now the leading cause of death for adolescents in Africa, and the second leading cause of death among adolescents globally.
The Atlantic's James Hamblin explores how our obsession with smartphones could stifle creative impulses.
Findings advance efforts to identify who would benefit from more aggressive therapy at earliest stages.
A molecule that can block the progress of Alzheimer’s disease at a crucial stage in its development has been identified by researchers in a new study, raising the prospect that more such molecules may now be found.
A MIT researcher wants to bring advances in drug delivery and biomaterials to the clinic.
