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.

A marine heat wave in 2016 killed off a full third of Australia's Great Barrier Reef,

the largest coral reef system in the world. It's terrible watching your favorite ecosystems

slowly die. Carly Cankel is a marine biologist at the University of Southern California,

who's studied that coral bleaching event. Bleaching occurs when the waters around corals become too

cold or too salty or too hot, but mostly too hot. And then the symbiotic algae that live

inside corals, which are photosynthetic food factories, abandon the coral, which

causes them to die. Because they're losing their nutritional source, so they're essentially

starving to death. But coral can house multiple species of algae, some more heat-tolerant than others.

So sometimes, in the face of stress, the hardier algae proliferate, and that change offsets

the damage caused by the exodus of the more

sensitive species. Now, process is called shuffling. Kankal and her colleagues studied shuffling

and corals affected by the 2016 bleaching event on the Great Barrier Reef, and they found that

adult corals can actually pass those reshuffled algal residents along to their offspring and their

eggs, pointing to a possible way successive generations of coral could adapt to warmer waters.

If your mom can kind of prime you for the environment that you might be experiencing,

that presumably would improve your fitness. The details are in the journal's scientific reports.
