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.

If you need a new liver, doctors have about 12 hours to transport it from a donor. That ticking clock severely limits the ability of doctors to get organs to patients.

Now researchers have demonstrated a method that kept rot livers viable up to four days. The scientists lowered the

livers to below freezing temperatures while flooding the tissue with antifreeze chemicals to prevent

the formation of damaging ice crystals. But such cooling alone is not sufficient, due in part to the

liver's wide variety of cell types and functions. So the researchers also used machine perfusion.

As the livers were cooled, they were flushed with

solutions that kept them operational. They were perfused again as they were brought back to above

freezing temps. All the rats that were implanted with three-day-old livers survived for three

months. Nearly 60% of the rats with four-day-old liver survived. In contrast, no rats that received

three-and-four-day-old livers preserved by

currently used methods survived. This work is an early step towards creating a system that could

work in humans, which would dramatically improve the chances of getting organs to people who

desperately need them. Thanks for the minute. For Scientific American 60 Second Science, I'm
