Scholars from diverse fields have long proposed that interlocking factors such as cognitive abilities, discrimination and interests may cause more women than men to leave the science, technology, engineering and mathematics (STEM) pipeline after entering college. Now a new Northwestern University analysis has poked holes in the much referenced "leaky pipeline" metaphor.
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.
Bacteria are most familiar through their roles in harmful infections. But scientists have realized that such bacteria are only a tiny fraction of the bacterial communities that live in and on our bodies. Most bacteria are commensal, which means they do not cause harm and often confer benefits.
There is no way to spot Alzheimer's early, no effective treatment and no known cure.
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.
The device goes beyond cochlear implants that have brought hearing to many deaf children but that don't work for tots who lack their hearing nerve.
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.
Cells lining the intestinal tract form a critical barrier, protecting our bodies from the billions of bacteria living in the gut.
Problem gambling and obsessive-compulsive behaviors share genetic as well as behavioral links, according to a new study.
This winter's nasty flu season has peaked and is clearly retreating, a new government report shows.
Engaging in unprotected sex with multiple partners increases the risk of contracting multiple strains of HIV, the virus that causes AIDS. Once inside a host, these strains can recombine into a new variant of the virus.
Microbes, small and ancient life forms, play a key role in maintaining life on Earth. As has often been pointed out, without microbes, we’d die—without us, most microbes would get along just fine.
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.
Receiving the human papillomavirus vaccine does not increase rates of sexually transmitted infections (STIs) in adolescent females. The vaccine, which can prevent cervical cancer in women, has had a low uptake, partly because of concerns about how it will affect adolescent sexual activity.
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.
Stating that sleep is an essential biological process seems as obvious as saying that the sun rises every morning. Yet, researchers' understanding of the molecular mechanisms underlying the effects of sleep loss is still in its earliest stages.
Damage to the brain's outer layer caused by smoking may be reversible after quitting, but it could take years, a study said. Brain scans of 500 Scottish septuagenarians confirmed a link between smoking and an acceleration of age-related thinning of the cortex—the outer layer of grey matter, researchers reported.
In the social world, people constantly gather information through visual cues that are used to evaluate others and interact. A new study from researchers at the University of Missouri determined that babies can make sense of complex social situations, and that they expect people to behave appropriately.
Firsthand experience working in hospitals and clinics helped inspire third-year Stanford medical student Pelu Tran to explore a potential career path in the world of high-tech startups.
