New research sheds light on origins of cryptococcal fungal infection

New research has shed light on the origins of a fungal infection which is one of the major causes of death from AIDS-related illnesses. The study, published today in the journal PLoS Pathogens, funded by the Wellcome Trust and the BBSRC, shows how the more virulent forms of Cryptococcus neoformans evolved and spread out of Africa and into Asia.

Structured exercise training can reduce HbA1c levels in patients with diabetes

Implementing structured exercise training, including aerobic, resistance or both, was associated with a greater reduction in hemoglobin A1c levels for patients with diabetes compared to patients in the control group, and longer weekly exercise duration was also associated with a greater decrease in these levels, according to results of an analysis of previous studies, published in the May 4 issue of JAMA.

TPO antibodies linked to abnormal thyroid levels in women after giving birth

Almost 1 in 20 women who gives birth will go on to develop thyroid problems within two years, according to a new study presented at the European Congress of Endocrinology in Rotterdam. This could have significant implications for the future health of the mother and child, as well as potentially presenting problems for future pregnancies.

Invention of optogenetics sheds light on how brain works

Commenting on Edward Boyden's article, Ben Barres, Head of the Neuronal & Glial Cell Biology Section of Faculty of 1000 and Professor at Stanford University School of Medicine said: "There will probably be a Nobel prize for optogenetics someday as it has revolutionized our attempts to understand how the brain works. This article provides a fascinating insight into the birth of optogenetics and the roles of the major players."

Fat-loss leads to earlier death in mice

Since the 1930s scientists have proposed food restriction as a way to extend life in mice. Though feeding a reduced-calorie diet has indeed lengthened the life spans of mice, rats and many other species, new studies with dozens of different mouse strains indicate that food restriction does not work in all cases.

Viewpoints: Dem representatives on health spending; Star Tribune praises IPAB; NY Times on stem cells

When the debate over the fiscal 2012 budget began, the country — or, more accurately, the media — was focused on Rep. Paul Ryan's proposal. Introduced on behalf of the Republican House majority, our colleague's plan puts the interests of wealthy corporations first by slashing Medicare and Medicaid and spending trillions on a new corporate tax cut. Indeed, cutting is all it seems to do. ... That's not a jobs plan — that's an economic death sentence.

Mirror neuron system in individuals with autism is not actually broken, but simply delayed

Developmental abnormalities in the mirror neuron system may contribute to social deficits in autism. The mirror neuron system is a brain circuit that enables us to better understand and anticipate the actions of others. These circuits activate in similar ways when we perform actions or watch other people perform the same actions.
