Exercise offers protection against Alzheimer's

Higher levels of daily physical activity may protect against the cognitive decline and neurodegeneration (brain tissue loss) from Alzheimer's disease (AD) that alters the lives of many older people, researchers from Massachusetts General Hospital (MGH) have found. In a paper in JAMA Neurology, the team also reported that lowering vascular risk factors may offer additional protection against Alzheimer's and delay progression of the devastating disease. The findings from this study will be presented at the Alzheimer's Association International Conference (AAIC) in Los Angeles by the first author of the study, Jennifer Rabin, Ph.D., now at the University of Toronto, Sunnybrook Research Institute.

A layer of 'aerogel' could make Mars habitable and even enable life to develop there

Transforming the red planet to support life has long been a dream of science fiction. Mars is now too cold to support life. Its atmosphere is also too thin to protect any living organisms from harmful radiation. But a new study suggests that local conditions could be changed using an inch of "aerogel"—a synthetic and ultralight material made by taking a gel and replacing the liquid component with a gas.
