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.

To us humans, climate change feels like something that's happening to the atmosphere.

But most of the action is actually at sea.

About 90% of the heat that gets trapped by greenhouse gases is absorbed by the ocean.

So it's really important to track that energy in the climate system and track the warming off the ocean. So it's really important to track that energy in the climate system

and track the warming off the ocean.

Of course, the ocean is really big and taking its temperature is hard.

Satellites give information about the surface,

and scientists have launched drifting devices

that measure conditions

in the upper mile of water, but researchers still struggle to collect data from the deep ocean

and to detect the long-term trends underlying day-to-day variations in temperature.

Now, however, scientists have developed a new technique that allows them to measure temperature

changes across entire ocean basins.

The idea dates back to the 1970s when researchers first proposed using sound waves to study ocean warming,

because the speed of sound through water depends on the physical properties of that water,
