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 Americans' 60-second science. I'm Jason Goldman. Got a minute?

In April, the world learned that more than 90% of Australia's Great Barrier Reef had become bleached.

Warming waters or other conditions caused the algae living inside the coral to exit, leaving the coral weak.

It's a bleak statistic because it's reasonable

to assume that as the corals themselves suffer, the entire ecosystem they support suffers as well.

For example, a study finds that bleaching hinders fish from learning to avoid predators.

Imagine you're a fish, and suddenly one of your friends meets its unfortunate end

in the jaws of a predator. We found that these animals actually have this really

sophisticated way of learning, which involves the linking of chemical alarm cues, which damage

release cues from constipistics, and any other smell or even the site of anything novel.

Sort of Pavlov's dog-type scenario.

James Cook University marine scientist Mark McCormick.

He and his team found that this learning process breaks down when the coral becomes bleached.

Instead of hosting algae within, the bleached coral becomes

blanketed by algae. We've used little patches of live coral and little patches of dead

and degrading coral, which has similar topographic complexities. And what we've done is we

put those little patches within a bed of even live coral or dead and degraded coral.
