Understanding the human body is a team effort. That's where the Yachtel group comes in.

0:05.8

Researchers at Yachtolt have been delving into the secrets of probiotics for 90 years.

0:11.0

Yacold also partners with nature portfolio to advance gut microbiome science through the global grants for gut health, an investigator-led research program.

J-P. That's Y-A-K-U-L-T dot C-O.J-P. When it comes to a guide for your gut, count on Yacolt.

This is Scientific Americans' 60-second science. I'm Steve Merski.

Photosynthesis is surprisingly inefficient, only of the order of 1 to 2%. And one of the main culprits is an enzyme called Robisco.

0:47.2

Laura Barter, a biological chemist at Imperial College London.

Scientific American editor-in-chief Mar Mariette de Christina recorded these comments

0:55.6

when they chatted at the recent World Economic Forum in Davos. That enzyme Rubisco? Because it's

1:02.0

vital for the first major step in photosynthesis, it's probably the most abundant enzyme on the planet.

1:08.0

And it's worked fine for a very long time. But for our needs, we humans

1:13.2

want it to work better. And I'm very interested in trying to improve upon this enzyme because

1:18.6

it's both slow and it also suffers from a lack of specificity. And it can catalyze a reaction with

1:25.9

carbon dioxide that you want, but also a competing

1:28.7

reaction with oxygen. And so we're looking at ways that we can enhance the local concentration

1:34.3

of carbon dioxide around Robisco to increase its efficiency and ultimately increase crop yield.

1:40.7

Barta explained how she's trying to do that at a talk she gave at the forum.

1:45.4

There are a suite of enzymes that are involved in the capture and release of carbon dioxide,

1:50.5

and we're synthesizing some molecules that can mimic this behavior,

1:55.1

with the hope that they can be sprayed on crops much in the same way as a fertilizer,

2:00.1

and will be taken up by the plant and will
