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.

You'd think that the asteroid that hit Earth 66 million years ago with enough force to wipe out the dinosaurs would be a tough thing to sleep through.

But a new study suggests that the ability to engage in extended hibernation might be what saved ancestral mammals from extinction at the end of the Cretaceous. The hypothesis is in the

proceedings of the Royal Society B. It's thought that global wildfires engulfed the planet

for a year or more after the Chixiloop impact. That's a long time to stay out of harm's way.

Small mammals most likely burrowed underground.

But could they last that long without coming up for air?

Yes, if they were hibernating.

We know that bears can sleep through winter,

but bunny-sized Madagascar mammals called Tenrecks have got that beat.

Researchers tagged two dozen Tenrecks with devices that recorded their body temps

and then released them back

into the wild. Most of the ten wrecks got killed by dogs or snakes or poachers, but a couple

tunneled into the sand where they proceeded to snooze until the researchers dug them up nine months

later. The findings reveal that on occasion, the best way to make it through a crisis is to
