Study delivers protein across blood-brain barrier to degrade Alzheimer's plaques Biologists substantially degraded Alzheimer's plaques in mice brains and human brain tissue by sending a fused protein across the blood-brain barrier. Their technique not only offers...

Gene found to be crucial for formation of certain brain circuitry Using a powerful gene-hunting technique for the first time in mammalian brain cells, researchers report on a gene involved in building the circuitry that relays signals through the brain. The gene is a...

Radiographic imaging exposes relationship between obesity, cancer Researchers are working to improve understanding about obesity and cancer. A study published today is the first to use direct radiographic imaging of adipose tissue rather than estimates like body mass...

Gene therapy bolsters enzyme activity to combat Alzheimer's disease in mice Scientists have identified an enzyme that can halt or possibly even reverse the build-up of toxic protein fragments known as plaques in the brains of mice with Alzheimer’s disease....

Bothersome pain afflicts half of older Americans Findings from a unique study underscore need for public health action on pain and disability in the elderly. First Nations adults have more than double risk of end-stage kidney disease First Nations adults with diabetes...

Good news on the Alzheimer's epidemic: Risk for older adults declining Improvements in education levels, health care and lifestyle credited for decline in dementia risk.

Buildup of amyloid in brain blood vessels promotes early cognitive impairment A team of researchers has discovered in a model of Alzheimer’s disease that early accumulation of a small protein, known as amyloid β, in the blood vessels of the brain can drive early...

Vitamins: Potential damage to body's defences Vitamin supplements are a billion-dollar industry. We want to stay healthy and fit and help our bodies with this. But perhaps we are achieving precisely the opposite? Regular physical activity in later life boosts...

Alzheimer's, vascular changes in the neck An international research team studying Alzheimer's and mild cognitive impairment is reporting potentially significant findings on a vascular abnormality outside the brain. Broken cellular 'clock' linked to...

Investments in aging biology research will pay longevity dividend Finding a way to slow the biological processes of aging will do more to extend the period of healthy life in humans than attacking individual diseases alone, according to some of the nation's top...

Stress, isolation take toll on those under 50 with HIV; older people fare better Researchers were surprised to learn that people younger than 50 years old with HIV feel more isolated and stressed than older people with the disease. They expected their study to reveal...

Aging erodes genetic control, but that's flexible In yeast at least, the aging process appears to reduce an organism's ability to silence certain genes that need to be silenced. Now researchers who study the biology of aging have shown that the loss of genetic...

Inflammatory skin damage blocked by bleach solution in animal study Processes that age and damage skin are impeded by dilute bleach solution, according to a new study by researchers working with mice. Tipping the balance between senescence, proliferation p53 is...
