Restricted Diet Affects Surgery Risk

surgery lSeveral days on a restricted diet may help the body better cope with the stress of surgery. New findings from a mouse study point the way toward potential strategies for reducing surgical risks in people....

Fending Off Cardiovascular Disease

debate1 cropA new study confirms that controlling traditional risk factors for cardiovascular disease, such as high blood pressure, substantially lowers the chance of major events like heart attack or stroke over the course of a lifetime....

Looking Inside Viruses

Looking Inside VirusesSince the discovery of the microscope, scientists have tried to visualize smaller and smaller details of cells and microbes. Now, researchers have developed a new way to see tiny structures within viruses....

Manganese May Prevent Toxin Damage

A new study suggests that manganese, an essential nutrient, may prevent the deadly effects of Shiga toxin. E. infections, which currently affect millions worldwide.

Foodborne illness is often caused by bacteria...

How Often Should Women Have Bone Tests?

bone lExperts recommend that older women have regular bone density tests to screen for osteoporosis. But it's been unclear how often to repeat the tests. A study of nearly 5,000 women now reports that patients with healthy bone density on their first test might safely wait 15 years...

Body Produces “Industrial” Lubricant for Metal Hip Implants

Graphic of hip showing metal-on-metal implant.

A lubricating layer made of graphitic carbon naturally forms in the joints of metal-on-metal hip implants, a new study shows. This solid layer, produced within the body, is more like an industrial lubricant than joint fluid. The finding may help researchers design longer-lasting metal-on-metal hips for...

New Insights Into Old Anti-Fungal Drug

For more than 50 years, doctors have used the drug Amphotericin B (AmB) to treat systemic fungal infections. In a new study, researchers revealed a novel mode of action for the drug. Their findings could lead to safer and more effective anti-fungal medications....

Researchers Find Cause of Rare Immune Disease

Immune lNIH scientists have identified a genetic mutation that causes cold temperatures to trigger allergic reactions—a condition called cold urticaria. In addition to pointing the way toward a potential cure, this finding will help shed light on how the immune system functions....

Most Stillbirths Caused by Placental, Pregnancy Conditions

stillbirths lHalf of all stillbirths result from pregnancy disorders and conditions that affect the placenta, according to a new report. Risk factors already known at the start of pregnancy—such as previous pregnancy loss or obesity—accounted for only a small proportion of the overall risk of stillbirth....

Gene Therapy Helps Patients with Hemophilia

A single dose of an experimental gene therapy boosted production of a missing blood-clotting factor in people with hemophilia, a new study shows. The therapy might give patients a long-term solution for preventing dangerous bleeding episodes....

Rats Show Empathy, Too

A new study shows that empathy may drive rats to help each other. The finding gives insight into the biological roots of our urge to assist others in need. The model the researchers developed will also provide an opportunity for further study....

Less Medication Effective for Wheezing Preschoolers

wheezing lChildren with recurrent wheezing who are in danger of developing asthma fared no better taking daily low doses of inhaled corticosteroid than taking higher doses only as needed. The children given treatment only as needed received far less total medication during the yearlong study....

Prenatal Steroids Reduce Brain Injury in Preemies

preemies lSome of the tiniest premature babies are more likely to survive and have less brain injury if their mothers receive prenatal steroids. The finding provides the first strong evidence that steroids can benefit preemies born as early as the 23rd week of pregnancy....

Antibodies Protect Against HIV in Mice

Researchers have devised a gene transfer technique in mice that, with a single injection, protects the immune cells that HIV targets. With further development, the approach may prove effective at helping to prevent HIV infection in people....
