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.

Warmer, more acidic oceans are already damaging corals in the South Pacific.

But the corals also have more visible foes, such as Crown of Thorn's sea stars.

It's an underwater swarm of locusts with a stomach that can be turned wrong side out and digest you as it walks across.

Mark Hay, a marine ecologist at Georgia Tech.

You just look in front of them and there's good corals and you look behind them and there's

these white skeletons.

Hay says the corals in Fiji's marine protected areas are particularly vulnerable to attack.

So he and his colleague Cody Clements took a closer look at the underwater

ecosystem there. And they discovered something weird. Neighboring seawedes usually compete for

resources with corals to the point where they'll whip corals with their fronds and poison them with

toxins. But the researchers found that in this case, the seawedes were actually saving the corals, blocking the marauding sea stars.

And so these competitors were really acting as kind of bodyguards for the corals once things got bad.

Hay and Clements replicated those observations in underwater experiments, in which even fake seaweed did the trick,

suggesting that seaweed is simply passively blocking the predators. The findings appear in the

proceedings of the Royal Society B. The marine reserves in Fiji are relatively small, and they
