Great news for all those women (and men) who have wanted to try the beautifying effects of snail slime but could never get past the “ick” factor. 20yrsyounger.com promises to get rid of the Ewww… while still letting women reap the anti-aging and rejuvenating benefits of snail slime cream. The process itself is called lyophilisation […]

Clues in H7N9 Influenza Genetic Sequences Researchers quickly evaluated the genetic sequences of the novel H7N9 avian influenza virus that’s caused illness and death in China in recent weeks. The analysis provides clues to the virus’s origin, transmissibility and potential sensitivity to existing treatments. Transmission electron micrograph of the new influenza A (H7N9) virus.

Arrestin Developments Researchers visualized a key step in how signals from outside the cell are muted within. The finding gives insight into the complex system that controls how all the cells in our bodies behave. This knowledge could have implications in the design of many drugs. Activated ß-arrestin-1 (yellow) binds a G-protein coupled receptor (green) […]
Red Meat-Heart Disease Link Involves Gut Microbes The link between red meat consumption and heart disease, a study suggests, may stem from gut microbes breaking down carnitine, a compound found in red meat. People who eat a lot of red meat have an increased risk for cardiovascular disease. The saturated fats and cholesterol in meat […]
Cholesterol as Target for Age-Related Vision Loss A study in mice suggests that targeting cholesterol metabolism in the eye may help prevent progression of a severe form of age-related macular degeneration (AMD), one of the most common causes of blindness in older Americans. An eye affected by neovascular AMD, filled with abnormal blood vessels and […]
Seeing Into the Brain Researchers developed a technique that preserves the brain’s 3-D structure down to the molecular level. The accomplishment allows study of the brain’s inner workings at a scale never before possible. … A thick slice of a mouse brain’s memory hub, or hippocampus, reveals projecting neurons (green), connecting interneurons (red) and layers […]
Gut Microbes Affect Weight After Gastric Bypass A study in mice suggests that gastric bypass surgery may result in weight loss in part by altering microbes in the gut. The finding may lead to a better understanding of how microbes influence energy balance. A gut microbe. Image by David Gregory and Debbie Marshall. All rights […]
Research Hints at New Approach to Addiction A study in rats found that stimulating a specific part of the brain reduces compulsive cocaine seeking. The finding suggests a potential approach to changing addictive behavior. Compulsive drug taking, which brings a range of negative health and social consequences, is one of the most challenging aspects of […]
Sensing Temperature Researchers discovered that distinct sets of neurons respond to heat and cold. The findings provide an elegant explanation for how mammals sense temperature. Thermosensation—the ability to detect temperature—triggers our reflex to withdraw from painful heat or cold. But mammals are also able to detect more pleasant cool and warm temperatures. We sense temperature […]
Weight Loss in People with Serious Mental Illness A new study showed that a weight-loss intervention can help overweight and obese people with serious mental illnesses—such as schizophrenia, bipolar disorder and major depression—lose significant weight and keep it off. More than 80% of people with serious mental illnesses are overweight or obese—a major factor that […]
Chelation Therapy May Help Reduce Cardiovascular Events In a new study, chelation therapy—an unproven alternative treatment for heart disease—modestly reduced cardiovascular events in older adults who’d suffered a prior heart attack. The findings weren’t conclusive but provide guidance for future research. Chelation is a chemical process in which certain compounds bind heavy metals and minerals […]
