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.

Last Christmas, Santa Claus must have been loading his sleigh in a t-shirt and shorts.

Temperatures at the North Pole crept up toward the freezing point when they should have been minus 20 Fahrenheit.

The heat wave was the latest in a series that have swept over the Arctic in recent winters.

Climate change has caused steady warming in the region, but it over the Arctic in recent winters. Climate change has caused

steady warming in the region, but it's also helped supercharge these extreme events, which

scientists say are tied to storms that spiral north out of the Atlantic. These winds, they actually

pick up a lot of heat and moisture. Vladimir Alexey, a climate scientist at the University of Alaska Fairbanks.

And the atmosphere carries all this extra moisture and heat to the Central Arctic, which results in warmer and moisture atmosphere.

Which then warms the surface. Alexiev says the heat ferried north by these storms helps slow the growth of sea ice in winter,

causing it to be about 15 centimeters thinner by the end of the season.

And thinner ice may have a harder time surviving the summer.

But while the impact of these storms has grown in recent decades,

the storms themselves are not happening more often, Alexiev says.

An important piece of information is that the frequency of those storms is not changing.

What's changing is the area of open water in those regions.

As the Atlantic Ocean has warmed up, the amount of sea ice around Scandinavia and Siberia and winter has decreased.
