Colonoscopies Prevent Colon Cancer Deaths Removing polyps during colonoscopy can not only prevent colorectal cancer, but also reduce deaths from the disease for years, according to a new study. Colorectal cancer is one of the most common cancers in both men and women nationwide. In 2012, more than 143,000 people in the United States […]

Bacteria’s Contracting Syringe Machine Some bacteria, such as those that cause cholera, use a special system to inject toxins into the cells of host organisms and other bacteria. A new study has revealed how this syringe-like injection system works at a molecular level. A bacterium delivers a lethal injection to another cell. Illustration by Everett Kane. […]

Drug Improves Alzheimer’s-like Condition in Mice Scientists report that a decade-old cancer drug quickly clears proteins linked to Alzheimer’s disease from the brains of mice. The drug restores memory, social behavior and other defects often seen with the disorder. But more study will be needed to see if the medication is safe and effective for […]

Tai Chi Increases Balance in Parkinson’s Patients People with Parkinson’s disease often have problems with balance and can suffer life-threatening falls. For patients with mild to moderate cases, a new study suggests that the ancient art of tai chi may significantly improve balance and reduce falls. Parkinson’s disease, which affects up to 1.5 million Americans, […]

Using Autoinjectors to Treat Seizures Drug delivery into muscle using an autoinjector—akin to the EpiPen used to treat serious allergic reactions—can be a fast, effective way to stop prolonged epileptic seizures. The finding provides a safe tool to treat people quickly during an emergency. Epilepsy is a brain disorder in which nerve cells in […]
Scientists Find Target for Resveratrol 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 certain age-related health problems. […]

Genes Affect Sex Differences in Behavior 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 hormones, such […]

New Method Builds Bone 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. Scanning electron micrograph of osteoporotic bone.

Fending Off Cardiovascular Disease A study of data from over a quarter of a million people confirmed that traditional risk factors for cardiovascular disease (CVD), such as high blood pressure, substantially raise the chance of major CVD events like heart attack or stroke over the course of a lifetime. The finding reinforces the importance of […]
Restricted Diet Affects Surgery Risk A new study in mice suggests that several days on a restricted diet may help the body better cope with the stress of surgery. The findings point the way toward potential strategies for reducing surgical risks in people. When blood flow to an area stops during surgery and is then […]
