Scientists reveal how beta-amyloid may cause Alzheimer's Scientists have shown how a protein fragment known as beta-amyloid, strongly implicated in Alzheimer's disease, begins destroying synapses before it clumps into plaques that lead to nerve cell death.

Fluorescent compounds allow clinicians to visualize Alzheimer's disease as it progresses What if doctors could visualize all of the processes that take place in the brain during the development and progression of Alzheimer's disease? Such a window would provide a...

What a pain in the… groin She wasn't born this way, but even Lady Gaga experienced groin pain -- typically a symptom of hip disease such as arthritis of the hip -- or, in her case, a hip labral tear. Groin pain is a common health complaint; one in four people develop...

Lifestyle changes may lengthen telomeres, a measure of cell aging A small pilot study shows for the first time that changes in diet, exercise, stress management and social support may result in longer telomeres, the parts of chromosomes that affect aging. Use of...

Americans living longer, more healthy lives In a first-of-its-kind study, researchers have found that the average 25-year-old American today can look forward to 2.4 more years of a healthy life than 20 years ago while a 65-year-old today has gained 1.7 years. A...

Test could identify which prostate cancers require treatment The level of expression of three genes associated with aging can be used to predict whether seemingly low-risk prostate cancer will remain slow-growing, according to researchers. Use of this three-gene...

Three of four cases of bladder cancer display mutations in the same gene Mutations in a specific gene has been found consistently in regulatory elements at early development stages of urinary bladder tumors, suggesting the analysis of this gene in urine samples may be...

Prion-like proteins drive several diseases of aging Two leading neurology researchers have proposed a theory that could unify scientists' thinking about several neurodegenerative diseases and suggest therapeutic strategies to combat them. Children with behavioral...

Megabladder mouse model may help predict severity of pediatric kidney damage A new study of the megabladder mouse model suggests that tracking changes in the expression of key genes involved in kidney disease could help physicians predict the severity of urinary tract...

The 'weakest link' in the aging proteome Proteins are the chief actors in cells, carrying out the duties specified by information encoded in our genes. Most proteins live only two days or less, ensuring that those damaged by inevitable chemical modifications...
