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.

Head up to the mountains, and if the steep trails don't slow you down, the thin air will.

There's less oxygen up there, so strenuous activity can leave you dizzy, out of breath, or worse.

But even though you're beaten, biochemical processes are already busy at work, acclimating your body. Scientists

investigated those pathways in humans and mice. They found that exposure to low oxygen depletes

stores of a red blood cell protein. It's called E-E-E-N-T-1. And that's a good thing, because now

other substances that protect your body against low oxygen are free to rapidly accumulate

and help the body adapt.

But here's the kicker. Once the E-E-N-T-1 protein goes away, it doesn't come back,

meaning red blood cells kind of remember their altitude exposure. And that means if you hit

the mountains again soon enough, you can acclimate faster than you did the first time. The findings are in the journal Nature Communications.

There is one caveat, though.

The red bloods lifespan is 120 days.

The longer you stay at sea level before you reclimbed the high altitude, then such

membrane will gradually disappear.

So unless you're a frequent mountain climber, there's really no shortcut to climatization.
