A duel between mathematical models supports the reigning theory of the genetics of altruism.

A Washington University in St. Louis drug discovery program has received three grants totaling more than $5 million from the National Institutes of Health (NIH) to develop new therapeutics for respiratory diseases. The target illnesses range from the common cold to life-threatening lung disease. 

Scientists have identified a gene that helps regulate how well nerves of the central nervous system are insulated, researchers at Washington University School of Medicine in St. Louis report.

A team of biomedical engineers at Washington University in St. Louis, led by Lihong Wang, PhD, the Gene K. Beare Distinguished Professor of Biomedical Engineering, has developed the world’s fastest receive-only 2-D camera, a device that can capture events up to 100 billion frames per second.

Any science textbook will tell you we can’t see infrared light. Like X-rays and radio waves, infrared light waves are outside the visual spectrum.

Damaged messenger RNA can jam cellular machines that make protein. The failure to clear the jams and chew up bad messengers is associated with neurodegenerative diseases such as Alzheimer’s.

As children, it was fascinating to put a flashlight up to our palms to see the light shine through the hand. Washington University in St. Louis engineers are using a similar idea to track movement inside the body’s tissues to improve imaging of cancerous tissues and to develop potential treatments.
