Understanding the human body is a team effort. That's where the Yachtel group comes in.

Researchers at Yachtolt have been delving into the secrets of probiotics for 90 years.

Yacold also partners with nature portfolio to advance gut microbiome science through the global grants for gut health, an investigator-led research program.

This is Scientific American's 60-second science. I'm Christopher in Taliatta.

Every year, 20 million tons of salt are dumped on roads and highways across the U.S. to eliminate ice.

And airlines spray up to 1,000 gallons of antifreeze on any one plane to de-ice it.

But now scientists have come up with what might be a more environmentally

friendly alternative. We've often heard the expression, it's time to fight fire with fire.

Well, I think now it's time to fight ice with ice.

Jonathan Barrico studies fluid mechanics at Virginia Tech. And what he means by that is if ice growth

is inevitable, why not design certain areas of plane wings or roads or HVAC

systems specifically to attract ice, to control the chaos and keep ice forming moisture

away from the rest of the surface? In other words, use ice itself as anti-freeze. To test that

idea, he and his team used lasers to cut tiny grooves into aluminum surfaces.

Those grooves, once filled with water and frozen, turned into tiny stripes of ice, which indeed

kept the rest of the surface 80 to 90 percent frost-free, even in incredibly humid cold air.

What's happening is the ice striped areas are just so attractive to the moisture,

but it kind of tractor beams, all the moisture that is going toward the surface, it kind of

tractor beams it toward the stripe regions preferentially, such that the intermediate areas,

if you design it right, just stay completely dry. You can find the results and some cool time-lapse
