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.

Polar bears and coral reefs are obvious victims of climate change, but a warming world will

also challenge many other animals, for example, cod.

The fish play a critical role in marine ecosystems and human economies. Climate change could devastate Atlantic and polar cod.

A team of scientists wanted to find out how rising sea temperatures and ocean acidification

might affect these fish populations.

We went out with our research vessel into the Baren Sea and caught Atlantic Cot and Polar Cot and brought them back alive

into a research facility in northern Norway.

Fleming Dock, a marine biologist at the Alfred Wagner Institute in Germany.

And in this facility, we raised the eggs and larvae under different temperature and ocean acidification,

mimicking the conditions expected for the next decades to come.

The researchers placed the eggs in larvae in various carbon dioxide concentrations,

as well as three different temperature scenarios.

One, the business as usual scenario, where humans continue to emit greenhouse gases at current

rates, and ocean waters increase 3 to 4 degrees Celsius.

They also tested an intermediate scenario of a 2 degree Celsius rise, and a best-case scenario where water temperatures rise only one degree.
