Researchers have identified a previously unknown effect of vitamin A in human embryonic development.
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.
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...
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.
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.
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.
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.
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.
Breast cancer, prostate cancer, and even routine infections. A new report ties these and other maladies to smoking and said an additional 60,000 to 120,000 deaths each year in the United States are probably due to tobacco use.
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.
Using the same technology that made smartphone cameras possible, scientists at Columbia University Medical Center are capturing images of individual molecules at a level of detail never before possible—including images of a molecule implicated in heart disease and muscle diseases.
"Washington University cardiologist Zachary Goldberger once made music out of heartbeats. Now, with a Beethoven scholar and a medical historian, he has discovered that three musical compositions that Beethoven created while stressed are arrhythmic in a way mirroring the composer's own probable heart arrhythmias."
Researchers have determined that two mutations on a single gene can interact in a way that lowers the carrier's risk for a heart attack. The variants are found in a gene called DBH, which regulates an enzyme involved in the conversion of dopamine to norepinephrine - both of which are important chemical messengers and hormones.
This is the first official look at the life sciences division of Google X.
The Food and Drug Administration (FDA) has approved for evaluating in people a nanoparticle-based imaging agent jointly developed at Washington University School of Medicine in St. Louis and the University of California, Santa Barbara, in collaboration with Texas A&M University.
Times have changed. It used to be that an apple a day kept the doctor away. But three recent studies indicate this mantra could be changed to “a blueberry- avocado-cocoa-bean-smoothie a day” keeps the doctor away—if the doctor is a cardiologist.
Patients with sickle cell disease often suffer from painful attacks known as vaso-occlusive crises, during which their sickle-shaped blood cells get stuck in tiny capillaries, depriving tissues of needed oxygen. Blood transfusions can sometimes prevent such attacks, but there are currently no good ways to predict when a vaso-occlusive crisis, which can last for several days, is imminent.
A see-through zebrafish and enhanced imaging provide the first direct glimpse of how blood stem cells take root in the body to generate blood.
Scientists are unraveling a mystery behind a fairly common disease that leads to heart failure: Why do some people with a key mutated gene fall ill while others stay healthy? Researchers tested more than 5,200 people to tease apart when mutations really are harmful or are just bystanders.
Researchers have found a possible predictor for little understood -- but often disabling or even fatal -- stroke complications.
Scientists have found that a transcription factor protein may be critical for normal respiratory function.
The fructose-glucose mixture found in high-fructose corn syrup was more toxic to mice than sucrose or table sugar.
Studies consistently show that people born weighing 6 pounds or less face an increased risk for type 2 diabetes as adults.
