What makes a bee grow up to be a queen? Scientists have long pondered this mystery. Now, researchers have fit a new piece into the puzzle of bee development — a piece that also illuminates understanding about our own development and aging. The study shows that a key protein in the insulin signaling pathway plays [...]

Researchers have made a major advance in treating people with a severe form of vasculitis, anti-neutrophil cytoplasmic antibody-associated vasculitis, a rare but devastating disease of blood vessels. In a six-month study, a new treatment strategy provided the same benefits as the current standard of care used for more than 40 years but required less frequent [...]
For 18 horrific hours on April 3, 1974, a cataclysmic group of tornados spun through and sacked 13 states and one Canadian province, ravaging some 900 square miles and killing 148 people.

A commercial brain fitness program has been shown to improve memory in older adults, at least in the period soon after training. The findings are the first to show that practicing simple visual tasks can improve the accuracy of short-term, or “working” visual memory. The research is also one of the first to measure both [...]
