Researchers have updated an extensive toxicology database so that it can be used to track...
Genetic testing company 23andMe Inc. will comply with a Food and Drug Administration directive...
Avian influenza virus H7N9, which killed several dozen people in China earlier this year, has not yet acquired the changes needed to infect humans easily.
Coffee and beer are polar opposites in the beverage world. Coffee picks you up, and beer winds you down. Now, researchers have discovered that the beverages may also have opposite effects on your genome.
A low level of daily exposure to a common component of sunlight can cause skin damage at the molecular level after just a few days. The find highlights the need for better sunscreens to protect against these damaging rays, and prevent the process that can cause skin to look old, wrinkled and sagging prematurely.
Mexican troops and federal police kept a nighttime watch on a rural field where thieves abandoned a stolen shipment of highly radioactive cobalt-60 while officials began planning the delicate task of recovering the dangerous material.
Human beings don’t come with power sockets, but a growing numbers of us have medical implants that run off electricity. Now, a group researchers is developing a safe, noninvasive and efficient means of wireless power transmission through body tissue.
X-rays cannot image the body’s soft tissues except with the use of contrast-enhancing agents that must be swallowed or injected. A new approach can change that, enabling the most detailed images ever— including clear views of soft tissue without any need for contrast agents.
A vaccine used to prevent tuberculosis in other parts of the world may help prevent multiple sclerosis (MS) in people who show the beginning signs of the disease.
One way to predict survival of many types of cancer is by counting the number of tumor-attacking immune cells that have migrated into the tumor in an effort to eradicate it– a sign of the body’s immune response to the cancer. However, quantifying these armies of immune cells has been difficult– until now.
New research on face transplants may help guide future operations for accident victims needing this kind of drastic surgery.
A newly discovered receptor in the body– similar to the receptors for endorphins or for morphine— might be important in the body’s response to sepsis, which could be the key to unlocking a new treatment in the future.
A novel compound selectively inhibits the process of aging in order to protect the brain from neurodegenerative diseases, without affecting lifespan.
The engineering feat that enables a device to jolt a dangerously misbehaving heart back to its normal rhythm and save millions of lives is featured in a new video.
For those living with gastrointestinal disorders, treatment often means quelling uncomfortable symptoms through medications or dietary changes. But researchers are aiming for a new treatment: doing away with the old gut for a new gut free of inflamed or diseased tissues.
In the five years since the "Octomom" case, big multiple births have gone way down, but the twin rate has barely budged. Now fertility experts are pushing a new goal: singletons.
Compared to traditional mammography, 3D mammography— known as digital breast tomosynthesis— found 22 percent more breast cancers and led to fewer call backs in a large screening study.
Researchers have discovered a protein that kills bacteria. The isolation of this protein, produced by a virus that attacks bacteria, is a major step toward developing a substitute for conventional antibiotics.
Cochlear implants allow deaf people to hear again by stimulating the auditory nerve directly. Researchers are working to overcome current limits of the technology using computer models.
A single dose of the hormone oxytocin, delivered via nasal spray, has been shown to enhance brain activity while processing social information in children with autism spectrum disorders.
Researchers have shown that synaptic health in the brain is closely linked to cognitive decline. They also discovered that estrogen restores synaptic health and also improves working memory.
Researchers have patented a quick, simple dipstick flu test using sugar labeled with gold. Quick diagnosis of flu is important because vaccination and antiviral drugs need to be administered to patients within 48 hours of infection to prevent new pandemics arising.
Researchers have identified a protein that causes loss of function in immune cells combating HIV. Disabling it could help restore the cells’ ability to combat the virus that causes AIDS.
Researchers have shown that they can grow unlimited quantities of intestinal stem cells, then stimulate them to develop into nearly pure populations of different types of mature intestinal cells.
Computer crashes should be giving way to insurance coverage— if the government's diagnosis of its health care website is correct.
A traveling medical technician who infected dozens of patients in multiple states with hepatitis C through tainted syringes is due to find out Monday how many decades he'll spend in a New Hampshire prison.
