Teenagers’ impulsive and risk taking behavior not related to brain deficit symptoms

A popular theory in recent neuroscience proposes that slow development of the prefrontal cortex - and its weak connectivity with brain reward regions - explains teenagers' seemingly impulsive and risky behavior.

Diet determines seizure latency: Estrogen production in the brain linked to omega-3 fatty acid intake

Scientists are increasingly appreciating estrogen's role in brain health. Now for the first time, production of estrogen in the brain has been directly linked to the presence of docosahexaenoic acid (DHA).

Study finds link between outdoor light at night and breast cancer risk

Women who live in areas with higher levels of outdoor light at night may be at higher risk for breast cancer than those living in areas with lower levels, according to a large long-term study from Harvard T.H. Chan School of Public Health. The link was stronger among women who worked night shifts.

Poor sleep in children linked to development of diabetes later in life

A latest UK study has found that deficiency of adequate sleep in children could be linked to their risk of developing diabetes later in life. The study notes that every extra hour of sleep a child gets per night is associated with a lower body weight and increased lean muscle mass and less blood sugar. The study is published this week in the journal Pediatrics.

USC scientists obtain molecular 'how to' guide for growing hair

How does the skin develop follicles and eventually sprout hair? A USC-led study, published in the Proceedings of the National Academy of Sciences (PNAS), addresses this question using insights gleaned from organoids, 3D assemblies of cells possessing rudimentary skin structure and function--including the ability to grow hair.

Immunotherapy shows promise in treatment of Type 1 diabetes

Around 1.25 million Americans are living with type 1 diabetes and 40,000 new cases are detected each year. In this condition body’s own immune system attacks and damages the insulin-producing β-cells inside the pancreas leading to impaired glucose metabolism in the body. There is no other treatment for this condition than regular painful insulin injections to maintain the normal insulin levels in the body. Type 1 diabetes is currently considered to be incurable.
