Race should no longer be used as a distinguishing factor in human biology and genetics research, contends a new paper in Science.
President Barack Obama is asking Congress for more than $1.8 billion in emergency funding to...
Ebola and now Zika are two viruses that have monopolized headlines for two years. But the Middle...
A new Neurology study, building on other evidence linking head injury to dementia, has found...
Researchers have identified a faulty signaling pathway that, when corrected in mice, ameliorates the symptoms of Rett syndrome, a devastating neurological condition. The findings could lead to the discovery of compounds or drugs that may benefit children affected by the disease.
Elastin is a crucial building block in our bodies. Its flexibility allows skin to stretch and twist, blood vessels to expand and relax with every heartbeat, and lungs to swell and contract with each breath. But exactly how this protein-based tissue assembles itself to achieve this flexibility remained an unsolved question — until now.
Two years ago, Ellen Martinsen, was collecting mosquitoes at the Smithsonian's National Zoo, looking for malaria that might infect birds--when she discovered something strange: a DNA profile, from parasites in the mosquitoes, that she couldn't identify.

Florida's history of fighting off mosquito-borne outbreaks puts the state in perhaps better position than most when it comes to the Zika virus.
Sweden's Karolinska University says it is commissioning an external investigation into stem-cell scientist Paolo Macchiarini, who was cleared last year of misconduct charges related to his creation of wind pipes made from patients' stem cells.
Chronic inflammation in the gut increases the risk of colon cancer by as much as 500 percent, and now researchers think they know why.
Increasing the level of a naturally-produced protein, called tristetraprolin (TTP), significantly reduced or protected mice from inflammation, according to researchers. The results suggest that pharmaceutical compounds or other therapeutic methods that produce elevated levels of TTP in humans may offer an effective treatment for some inflammatory diseases, such as rheumatoid arthritis, psoriasis, and multiple sclerosis.
Researchers have identified a striking signature in tumor DNA that occurs in five different types of cancer. They also found evidence that this methylation signature may be present in many more types of cancer. The specific signature results from a chemical modification of DNA called methylation, which can control the expression of genes like a dimmer on a light switch.
Building on research reported last year, researchers have succeeded in identifying the neurons that secrete the substance responsible for the plaques that build up in the brains of Alzheimer’s disease patients.
Scientists have created a new class of highly customizable biological sensors that can be used to form “logic gates” inside cells of the immune system, giving these cells the capability to home in on and kill a wide range of cancer cells while preventing them from attacking normal tissue.
A new study has found that using BMI to gauge health incorrectly labels more than 54 million Americans as “unhealthy,” even though they are not.
Depression can be a devastating and unremitting problem. Researchers of a new study report successful reduction of depressive symptoms in patients using a novel non-invasive method of vagus nerve stimulation, or VNS.
Johnson & Johnson, continuing its long quest for a Type 1 diabetes cure, is joining forces with biotech company ViaCyte to speed development of the first stem cell treatment that could fix the life-threatening hormonal disorder.
Engineers have developed the first fully integrated sensor system that can measure metabolites and electrolytes from sweat and sync the data in real time to a smart phone.
