Discovery of agents that speed up destruction of amyloid beta proteins

Taking a new approach to the treatment and prevention of Alzheimer's disease, a research team led by investigators at the Mayo Clinic campus in Florida has shown that druglike compounds can speed up destruction of the amyloid beta (A-beta) proteins that form plaque in the brains of patients with the disorder.

Autopsy study links prostate cancer to single rogue cell

One cell...one initial set of genetic changes - that's all it takes to begin a series of events that lead to metastatic cancer. Now, Johns Hopkins experts have tracked how the cancer process began in 33 men with prostate cancer who died of the disease. Culling information from autopsies, their study points to a set of genetic defects in a single cell that are different for each person's cancer.
