Acid-resistant bug doesn’t give in to alcohol either

A chemist at Washington University in St. Louis has found surprisingly tough enzymes in a bacterium that “just says no to acid.” Acid resistance is a valued trait for both pills and human pathogens.

Imaging technique detects plaques in Alzheimer’s disease

PET scans: normal (top 2 rows) and Alzheimer’s.After decades of searching, scientists finally may have identified a way to study Alzheimer’s disease changes in living human brains. Researchers at Washington University’s Alzheimer’s Disease Research Center (ADRC) have begun studies of an imaging agent developed at the University of Pittsburgh that could potentially detect amyloid plaques with a positron emission tomography (PET) scan, enabling earlier detection of the disease and improved testing of new treatments.
