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.

This is Scientific American's 60-second science. I'm Christopher in Taliatta.

Air conditioning and fans account for a full 10% of the world's electricity usage.

Or, to put it in another way...

It's a lot of air that you pump around.

Roland Dittmeyer, a chemical engineer at the Karls Rue Institute of Technology in Germany.

Another thing that takes a lot of pumping air around, he says,

carbon capture. Because the concentration of the CO2 in air is evidently quite low. Even though it's

enough to cause climate change, it's only 400 parts per million. So he says, why not retrofit

air conditioners with modules that capture carbon? Several companies

already make materials that strip carbon dioxide from the air. You'd then need to convert

that captured CO2 into hydrocarbons. That's an energy-intensive process, but Dittmeyer's vision

is that we'd use clean, carbon-free, renewable energy to power that step. Do this on a large

enough scale, and you could produce

significant amounts of this synthetic renewable oil. Dittmire and his colleagues calculated that

if you outfitted the AC system of the Fair Tower, a large skyscraper in Frankfurt, with these

carbon capture devices, the building's units alone could produce an estimated 15,000 barrels of synthetic oil a year.

The full write-up in the journal Nature Communications is called crowd oil, not crude oil.
