In one five-year period, college athletes suffered more than 10,000 concussions — one-third of them while playing football. But an unusual team-up has recently brought a new, biomarker-based concussion test one step closer.
Mammals might seem like better human stand-ins than a minnow’s striped cousin, but zebrafish resemble us in surprising and useful ways. But zebrafish also offer practical advantages over other model species: They’re cheap, hardy, breed like rabbits on Viagra, and their skin can be made transparent.
When cancer is detected, the interaction of two nanoparticles creates a bright yellow signal (photo by Fei Lu, Houston Methodist Research Institute).
Pancreatic cancer is the fourth leading cause of cancer deaths in the United States each year, in part because around four-fifths of cases go undetected until they have reached an advanced stage. But a new, biomarker-based test could soon change all that — and offer a way to monitor treatment outcomes.
The Centers for Disease Control and Prevention (CDC) reports that rates of diabetes-related kidney failure among Native Americans dropped more than 54 percent between 1996 and 2013.
The finding were published by CDC and the Special Diabetes Program for Indians (SDPI), a $150 million annual grant program coordinated by the Indian Health Service.

The book The Runner’s Brain told runners how their minds could change their running. Now a University of Arizona study says the reverse might be true as well.
Using functional connectivity MRI (fcMRI), they found significant differences in areas that are active when the brain is at rest. Possibly, such networks could play a key role in the effects of aging and neurodegenerative diseases.
