Men and women can seem like they’re from different planets sometimes. Hormones help drive those differences. A new study shows how genes pass on the message. Hormones are the body's signaling molecules. They affect many aspects of development and biology. Researchers have long known that the sex
...Researchers have developed a way to direct the body's own stem cells to the outer bone to build new, strong bone tissue. The method, developed in mice, may lead to new treatments for osteoporosis and other bone diseases that affect millions of people....
Resveratrol, a compound found most famously in grapes and red wine, seems to ward off several age-related diseases. However, its mechanism of action has been elusive. Researchers have now found a direct molecular target for the compound. The finding may lead to drugs that can prevent...
Modern social networks, from small networks of friends and family to entire countries, are based on cooperation. A new study suggests that our early ancestors may have had social networks strikingly similar to those of modern societies.....
Several 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....
A 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....
Since 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....
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...
Experts 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...
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....
NIH 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....
Sweet basil’s many herbal uses include culinary, landscaping, medicinal, and spiritual, and the essential oil can be found in fragrances and insect repellents. Cultivated largely as a culinary herb and often associated with Italian cuisine, basil is excellent in tomato-based dishes. It is also used cooked or raw in...
One of my first awakenings to the myriad benefits of community gardens was when the community police officer in a troubled neighborhood in Vancouver helped get one started. She wanted a project for the homeless people hanging around the neighborhood. They embraced it eagerly...
Half 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....
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....
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....
Children 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....
Some 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....
