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.

Global warming deniers love to point to colder snow as evidence against climate change,

like Oklahoma Senator James Inhoff.

Remember last year when he tossed a snowball in Congress?

You know what this is? It's a snowball.

And that's just from outside here. So it's very, very cold out, very unseasonal. So here, Mr. President, catch this.

With that, he offhandedly disproved decades of climate science, to some people at least. But such cold-influenced denial may be playing out across the U.S., in particular in Appalachia and the South,

because it turns out those areas have had lots of record low temperatures in the last 12 years,

and they're also, by and large, the same parts of the country that have high numbers of global warming skeptics.

So researchers have a theory that personal experience with

cold snaps could be trumping scientific facts. The analysis is in the proceedings of the National

Academy of Sciences. Study author Robert Kaufman, an environmental scientist at Boston University,

says the way around this might be to put climate data in terms people understand,

money.

We should propose a simple bet to climate skeptics, and that is, for every new record high

temperature at a weather station, you pay us a dollar, and for every new record low temperature, we'll pay you a dollar.

Or he says, think of climate change as a slot machine, especially with the president-elect.
