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 may have noticed your summertime electricity bills when you're cranking the AC.

They're more pricey than your wintertime payments.

That's because air conditioning is an electricity hog.

And when a whole city or region turns down the thermostat,

utilities have to meet that increased demand somehow.

This is often when we turn on the oldest power plants or the dirtier power plants.

Tracy Holloway, an atmospheric scientist at the University of Wisconsin and Madison.

Some of these older power plants that may run on fuel oil or may run on coal only come on the hottest days.

Using data from the EPA, Holloway and her team studied how air pollutants respond when the

temperature goes up. They found that across the eastern U.S., for every degree Celsius temperature

rise, power plants belched out 140,000 metric tons of additional carbon dioxide.

And emissions of the pollutants sulfur dioxide and nitrogen oxides

rose 3.5% per extra degree of heat, averaged across the region.

That's especially bad because hot summer days are the worst days to pump out more pollution.
