Researchers from the Hotchkiss Brain Institute (HBI) in the Faculty of Medicine at University of Calgary have uncovered the first evidence that neurons talk to ‘glial’ cells in the digestive tract: a discovery that could help find a way to regulate and restore balance in the gut for the one in 10 Canadians suffering from irritable bowel syndrome (IBS) and the more than 200,000 Canadians suffering from inflammatory bowel disease (IBD). 

Scorpions possess resistance to high temperatures and the ability to conserve water for long periods of time, and as a result thrive in hot and arid parts of the world. But is this global distribution also seen at a more local level?   Doctoral student Shmuel Raz and colleagues at the University of Haifa, Israel show that this is indeed the case, even when European-like and African-like habitats were separated by no more than 100 meters. 

Shmuel Raz and colleagues studied the communities of scorpions in a valley near Mount Carmel in Israel which has been dubbed "Evolution Canyon." Evolution Canyon" has steep slopes and runs approximately east-west, which means that the south-facing slope receive up to eight times as much solar radiation as the north-facing slope .

Soy aglycons of isoflavone (SAI), a group of soybean constituent chemicals, have been shown to promote health in a rat model of the menopause. The research in  Nutrition&Metabolism shows how dietary supplementation with SAI lowers cholesterol, increases the anti-oxidative properties of the liver and prevents degeneration of the vaginal lining.

Science has come one step closer to developing practical methods of gene therapy. Viable gene therapy means treatment for currently untreatable diseases including the vast amount of genetic disorders affecting millions world-wide.

According to a new study published by the Mayo Clinic, patients with Parkinson disease (PD) have another problem to deal with. Researchers have found that one in six patients taking therapeutic doses of
certain prescription drugs for management of PD have developed troubling behavioral symptoms. The most problematic symptoms include compulsive gambling and hypersexuality.

By combining the results of a number of powerful techniques for studying material structure at the nanoscale, a team of researchers from the National Institute of Standards and Technology (NIST), working with colleagues in other federal labs and abroad, believe they have settled a long-standing debate over the source of the unique electronic properties of a material with potentially great importance for wireless communications.

The new study* of silver niobate not only opens the door to engineering improved electronic components for smaller, higher performance wireless devices, but also serves as an example of understanding how subtle nanoscale features of a material can give rise to major changes in its physical properties.

Portuguese scientists discovered a new molecular mechanism that allows gamma herpes viruses to chronically infect patients and helps to explain why these patients present an abnormally high incidence of the lymphocyte (or white blood cell) cancer lymphoma, particularly when their immune system is compromised.

The research, just published in the advance online edition of The Embo Journal, reveals how these viruses mimic the host molecular machinery to shutdown NF-kB –a key regulatory protein complex involved in cell division and death – on infected lymphocytes, and how this - probably by disrupting the cells normal regulatory systems - creates the conditions for the development of lymphomas.

Before the invention of boxed chocolates, Corvettes and bling-bling, all a man had to do for sweet lovin' was provide his special ladies with meat.  Studies of extant hunter-gatherer societies show that literally bringing home the bacon leads to greater reproductive success.  Highly skilled hunters also partake in more extra-marital affairs and in polygamous societies, have more wives. 

Researchers at the Joslin Diabetes Center have demonstrated that adult humans still have a type of "good" fat previously believed to be present only in babies and children. Unlike white fat, which stores energy and comprises most body fat, this good fat, called brown fat, is active in burning calories and using energy. The finding reported in The New England Journal of Medicine could pave the way for new treatments both for obesity and type 2 diabetes.

Scientists had thought that brown fat only existed in humans during childhood and was mostly gone by adulthood. The paper shows that brown fat not only exists in adult humans, but also for the first time, that the fat is metabolically active.
