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.

Hi, I'm Scientific American Podcast editor Steve Merski.

And here's a short piece from the August 2018 issue of the magazine in the section called

Advances, Dispatches from the Frontiers of Science, Technology, and Medicine.

Taking Stock of Life by Andrea Thompson.

Plants rule the planet, at least in terms of sheer mass.

Many tallies of Earth's life use biodiversity as a measurement and simply count the number

of species.

A new census, based on biomass, compiled data from hundreds of studies to determine which

kingdoms, classes, and species carry

the most global heft. The results show that plants, primarily those on land, account for 80%

of the total biomass, with bacteria across all ecosystems a distant second at 15%. The findings were published in the

proceedings of the National Academy of Sciences. Higher resolution satellite data and improvements

in genomic sequencing have made such measurements possible by yielding more accurate estimates,

but the uncertainty is still high for hard-to-count life forms,

such as microbes and insects. Antarctic krill, a type of small crustacean, have a total

biomass comparable to that of humans. We make up only one one hundredth of a percent of the total,
