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.
Cells lining the intestinal tract form a critical barrier, protecting our bodies from the billions of bacteria living in the gut.
The Ebola virus remains viable for at least seven days after death in non-human primates. A new study, published in Emerging Infectious Diseases, suggests that Ebola transmission from deceased individuals may be possible for an extended period of time after death, underscoring the importance of using safe practices for handling corpses.
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.
Humans aren’t the only species to be influenced by spin. Our closest primate relatives are susceptible, too.
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.
Most of the genetic mutations that cause cancer result from environmental ‘damage’ (for example, through smoking or as a result of over-exposure to sunlight) or from spontaneous errors as cells divide.
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.
For decades, scientists have thought the bacteria that cause the bubonic plague hijack host cells at the site of a fleabite and are then taken to the lymph nodes, where the bacteria multiply and trigger severe disease. But UNC School of Medicine researchers discovered that this accepted theory is off base. The bacteria do not use host cells; they traffic to lymph nodes on their own and not in great numbers.
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.
Mice genetically deficient in serotonin—a crucial brain chemical implicated in clinical depression—are more vulnerable than their normal littermates to social stressors, according to a Duke study appearing this week in the Proceedings of the National Academy of Sciences.
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.
Silibinin has an outstanding safety profile in humans and is currently used for the treatment of liver disease and poisoning.
University of Chicago Medicine researchers have built a model system that uses multiple cell types from patients to rapidly test compounds that could block the early steps in ovarian cancer metastasis. Their three-dimensional cell-culture system, adapted for high-throughput screening, has enabled them to identify small molecules that can inhibit adhesion and invasion, preventing ovarian cancers from spreading to nearby tissues.
Scientists at The Scripps Research Institute (TSRI) have identified a new cellular pathway that is affected in cystinosis, a rare genetic disorder that can result in eye and kidney damage.
The researchers, from Cancer Research UK's Health Behaviour Research Centre at University College London (UCL), interviewed almost 1,900 people aged 50-80 years old about their views on cancer screening.
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.
