Tiny samples could yield big predictive markers for pancreatic cancer

A handful of proteins, detected in incredibly tiny amounts, may one day help doctors distinguish between a harmless lesion in the pancreas and a potentially deadly one, say researchers at Fox Chase Cancer Center.

Amyloid plaques may increase the activity of astrocytes

The impact of the amyloid plaques that appear in the brains of patients with Alzheimer's disease may extend beyond the deposits' effects on neurons – the cells that transmit electrochemical signals throughout the nervous system.
