Zebrafish Make a Big Splash in Arizona Medical Research

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.

Brain Activity Patterns Set Young Runners Apart from Healthy Peers

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.

Jeopardy-Winning Computer Crunches Numbers to Fight ALS

Barrow Neurological Institute is working with IBM’s Jeopardy-winning supercomputer, Watson, to identify treatment targets for Lou Gehrig’s disease, also known as amyotrophic lateral sclerosis, or ALS.

ALS is a poorly understood neuromuscular disease with only limited treatment options. Its capacity to strike anyone, at any time, seemingly without pattern, has puzzled researchers.

A Bizarre Bazaar of Food Facts

Food is both mundane and magical, ephemeral and essential – the ultimate cultural touchstone. Our religions proscribe taboo foods, oblige sacred meals and employ food as a conduit for sacred power. Our myths abound with divine edibles that grant gods immortality, while our folktales counsel against feasting in fairyland lest we trap ourselves forever.

But for all the reverence we pay them, many comestibles arose from humble, bizarre or even disgusting sources, while what we choose, or are compelled, to eat is driven by everything from necessity to neurosis. For better or worse, food scientists, molecular gastronomists and, yes, marketing  firms channel these impulses in profitable (if not always healthy directions). The results are, shall we say, appetizingly bizarre …

Nightmare Fuel: 10 of the CDC’s Deadliest Stockpiles

The Centers for Disease Control and Prevention has to walk a fine line. Saving people from the nastiest infectious diseases and bioterror attacks requires that they study those same viruses and bacteria. But even in one of the most carefully controlled and well-equipped facilities on Earth, items are occasionally mishandled or misplaced.

What’s the worst that could happen? It’s not a rhetorical question when we take a tour of …
