A recent finding about capsaicin from chili peppers curbing obesity in mice may be why nutritionists and diet marketing groups latch onto it in 2015. The world doesn't need another gimmick diet but clearly people need to eat less. Fully one third of the world is overweight, by World Health Organization estimates. Now a group at the University of Wyoming has found promise in the potential of capsaicin -- the chief ingredient in chili peppers -- as a diet-based supplement.

Small magnetic whirls may revolutionize future data storage and information processing if they can be moved rapidly and reliably in small structures. A team of scientists of Johannes Gutenberg University Mainz (JGU) and TU Berlin, together with colleagues from the Netherlands and Switzerland, has now been able to investigate the dynamics of these whirls experimentally. The skyrmions, as these tiny whirls are called after the British nuclear physicist Tony Skyrme, follow a complex trajectory and even continue to move after the external excitation is switched off. This effect will be especially important when one wants to move a skyrmion to a selected position as necessary in a future memory device.

Kalorama Information expects the market for plasma collection to grow, and to outpace overall blood collection through 2018. The primary market driver will be plasma-derived immunoglobulins (Ig) used to produce intravenous immunoglobulin (IVIG) therapies. The growth of mature markets associated with the collection, processing and therapeutic use of whole blood and derived products are by and large endangered without the robustness of the global plasma market. This is the finding of Kalorama Information's recent Blood: The Worldwide Market for Blood Products, Blood Testing, Blood Equipment, and Synthetic Blood Products.

A new study has shown an unprecedented degree of connectivity reorganization in newly-generated hippocampal neurons in response to experience, suggesting their direct contribution to the processing of complex information in the adult brain.

The hippocampus is an anatomical area of the brain classically involved in memory formation and modulation of emotional behavior. It is also one of the very few regions in the adult brain where resident neural stem cells generate new neurons life-long, thus providing the hippocampal circuitry with an almost unique renewal mechanism important for information processing and mood regulation.

Bariatric surgery improves life expectancy for many obese diabetic patients, but it may cut life expectancy for patients who are super obese with very high body mass indexes, according to a University of Cincinnati researcher.

"For most patients with diabetes and a BMI (body mass index) greater than 35, bariatric surgery increases life expectancy," says Daniel Schauer, MD, assistant professor in the Division of General Internal Medicine at UC. "However, the benefit of surgery decreases as BMI increases. The patients with a BMI over 62 likely don't gain any life expectancy with surgery."

The findings were published recently online in the Annals of Surgery.

Resveratrol found in common foods such as red grapes and peanuts may help prevent age-related decline in memory, according to a new paper.

Ashok K. Shetty, Ph.D., a professor in the Department of Molecular and Cellular Medicine and Director of Neurosciences at the Institute for Regenerative Medicine, has been studying the potential benefits of resveratrol, a controversial antioxidant that is found in the skin of red grapes, as well as in red wine, peanuts and some berries. Resveratrol has been promoted for its potential to prevent heart disease, but Shetty and colleagues believe it also has positive effects on the hippocampus, an area of the brain that is critical to functions such as memory, learning and mood.
