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.
