Early Epigenetic Effects in Alzheimer’s Disease Repression of certain gene activity in the brain appears to be an early event affecting people with Alzheimer’s disease, a new study found. In mouse models of Alzheimer’s disease, this blockade and its effects on memory were treatable. HDAC2 levels (red) are higher in cells from the hippocampus […]

Diesel Exhaust and Lung Cancer Deaths in Miners In a study of miners, scientists found that heavy exposure to diesel exhaust increased the risk of death from lung cancer. The risk may also extend to other workers exposed to diesel exhaust, as well as people living in urban areas with higher diesel exhaust levels. […]

Examining how friends and family can influence our weight loss As we’ve previously written about on Scope, research at Stanford has shown that patients who have undergone Roux-en-Y gastric bypass surgery can have a positive effect on family members’ weight loss. A segment today on NPR’s Morning Edition examines how social influences can fuel weight loss. On the show, John Morton, MD, […]

New York City health campaign nudges public to “burn calories, not electricity” On a recent tromp through the airport, I did something I haven’t done in a while: deliberately took the stairs instead of the escalator. For a while, I regularly eschewed moving walkways, elevators and escalators to increase my level of daily activity. But […]
How Sulfa Drugs Work Researchers have finally found out how sulfa drugs—the first class of antibiotics ever discovered—work at the molecular level. The finding offers insights into designing more robust antibiotic therapies. Bacillus anthracis. Image courtesy of CDC/ Dr. William A. Clark. Sulfa antibiotics were first used in the 1930s, and they revolutionized medicine. […]
Understanding the science and psychology of how habits work … … How to break habits (from The Power of Habit by Charles Duhigg) Previous research has suggested that making healthy lifestyle changes may improve our health and potentially prevent cancer, stave off Alzheimer’s, lower blood pressure and improve mental health. But, as many of us can attest, adopting healthier habits can be a […]

Stephen Wolfram reflects on the personal analytics of his life Stephen Wolfram, the creator of Wolfram|Alpha, has been collecting details on his intellectual and physical activity for over two decades. In a post yesterday on Wired’s Epicenter blog, Wolfram sifts through the massive volume of personal data and illustrates how such reservoirs of information can be used to teases out […]

New imaging technology may aid in early detection of breast cancer This kaleidoscopic image shows a live human mammary gland structure created by Purdue researchers working to develop a new imaging technology to determine a woman’s risk of developing breast cancer and advance research on methods for preventing the disease. Futurity reports: The new imaging technique, […]

New Stanford immune-system sensor may speed up, slash cost of detecting disease An inexpensive new medical sensor has the potential to simplify the diagnosis of diseases ranging from life-threatening immune deficiencies to the common cold, according to its inventors at the Stanford University School of Medicine. Their device, called an integrated microfluidics-waveguide sensor, sorts and counts […]
Study shows chronic stress in adolescence may impair memory As many of us have experienced, chronic stress can take a toll on your emotions and ability to think clearly. Now findings published in Neuronoffer new insights into how chronic stress may affect the brain during adolescence and adulthood. In the study (subscription required), University of Buffalo researchers analyzed […]
