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.

Solar companies are obviously in the business of building solar energy farms.

But here's another way the solar developers are spending their money

to protect and relocate desert tortoises from their sunny desert solar farms,

to the tune of at least $60 million.

It's an incredible amount of money to do something that is not necessary.

Not necessary to the generation of solar energy, that is, says Rebecca Hernandez, because

why not just put your panels elsewhere?

Hernandez, an Earth System scientist and ecologist at UC Davis, says the alternatives

to developing on wild lands

are many. Put photovoltaic panels over rooftops or parking lots, atop salty or contaminated land

unsuitable for farming. Or why not install floatovoltaics? A floatovoltaic is a photovoltaic

installation that is placed on pontoons that float on the water.

She and her colleagues identified one and a half million football fields worth of surface area on these types of alternative sites in California's Central Valley alone, with a combined energy generation potential of 4,300

terawatt hours per year, using the solar panels available on the market today.

That's enough to power the entire United States.

This paper isn't to say that we think that all energy should be derived from solar energy.
