New technologies will help the field of telemedicine drastically grow this year.
Researchers have identified a previously unknown effect of vitamin A in human embryonic development.
23andMe, Inc., the leading personal genetics company, today announced that it has been granted authority by the U.S. Food and Drug Administration (FDA) to market the first direct-to-consumer genetic test under a regulatory classification for novel devices.
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.
There is no way to spot Alzheimer's early, no effective treatment and no known cure.
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 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.
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.
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.
Ebola has claimed nearly 9,000 lives in West Africa over the past year, although new infections have dropped dramatically in recent months.
President Barack Obama's nominee to serve as U.S. drug "czar" won unanimous approval in the Senate Monday as lawmakers vowed to curb an epidemic that results in more than 40,000 deaths a year from overdoses of prescription painkillers, heroin and other substances.
In the 1980s, immunotherapy researcher Lieping Chen, M.D., Ph.D., embraced the career goal of curing one cancer. That lofty-seeming goal is beginning to look more modest today. Recent clinical trials have shown that one cancer after another is vulnerable to immune modulation therapy, a cancer-fighting strategy Chen pioneered that for years was considered marginal.
The drop-off in Ebola infections is good news for Liberia, but it means there are not enough sick people to take part in the study.
Federal health officials faced tough questions from lawmakers Tuesday about why they didn't take steps to produce a better flu vaccine as it became clear that this year's version wasn't going to offer much protection.
Every day in hospitals around the world, patients suffer painful allergic reactions to the medicines they are given. The reactions, known as pseudo-allergies, often cause patients to endure itchiness, swelling and rashes as an unwanted part of their treatment plan. The reactions can be so severe they may stop patients from taking their needed medications and sometimes can even prove fatal.
President Obama held a press conference revealing new details surrounding the Precision Medicine initiative he announced during the State of The Union.
This is the first official look at the life sciences division of Google X.
Killer T cells are one of the body's main lines of defense against pathogens.
The President briefly mentioned the project during the State of The Union earlier this week.
The human brain’s complexity makes it extremely challenging to study.
These factors may not be enough to finally end the Ebola epidemic in West Africa.
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.
The focus of this department is to study the convergence of health and data.
These companies have an interesting year ahead of them.
In the midst of a worrisome flu season, health officials are pushing doctors to prescribe antiviral medicines more often.
