Loneliness is bad for the heart

Loneliness is bad for the heart and a strong predictor of premature death, according to a new study. The study found that feeling lonely was a stronger predictor of poor outcomes than living alone, in both men and women….

Thorny life of new-born neurons

The hippocampus is a critical region in the brain for learning and memory. For the first time, scientists have observed how stimulation causes the spines on its neuronal dendrites to enlarge….

The cartography of the nucleus

A new technique creates maps of the folded structures of DNA, RNA, and proteins within the cellular nucleus, revealing elegant ‘hubs’ of organization….

New hope from the 'seven year switch' in Type 1 diabetes

A team found evidence that the amount of insulin produced declines by almost 50 percent each year for seven years. At that point, the insulin levels stabilize….

Face transplantation: An established option to improve quality of life in patients with severe facial trauma

Thirteen years after the first successful face transplant, US trauma surgeons should be aware of the current role of facial transplantation for patients with severe facial disfigurement — including evidence that the final appearance and functioning are superior to that provided by conventional reconstructive surgery….

Researchers reverse cognitive impairments in mice with dementia

Reversing memory deficits and impairments in spatial learning is a major goal in dementia research. A lack of knowledge about cellular pathways critical to the development of dementia has prevented significant clinical advance. Researchers are breaking through that barrier. They show, for the first time in an animal model, that a drug can reverse tau pathology — the second-most important lesion in the brain in patients with Alzheimer’s….

Virtual brain gives insights into memory deficits in depression

During a depressive episode the ability of the brain to form new brain cells is reduced. Scientists examined how this affects the memory with a computational model. It was previously known that people in an acute depressive episode were less likely to remember current events. The computational model however suggests that older memories were affected as well. How long the memory deficits reach back depends on how long the depressive episode lasts….

'Supersized alcopops' pose unique danger to youth

College students seriously underestimate the effects of drinking a new class of beverages being marketed across the country, according to a new study. ‘Supersized alcopops’ — sweet, colorful and fizzy drinks that have been shown to appeal to youth — now contain almost as much alcohol as a six-pack of beer in a single can, and young drinkers don’t know how much these drinks can affect them….
