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.

Happy New Year! And if you have been away from work for a few days, you deserve some time off.

After all, you've traveled far, even if you just stayed at home.

According to NASA, just by being on the planet Earth in the last year, you zipped about 584 million miles around the sun

at an average speed of about 67,000 miles per hour.

Hey, I wasn't speeding in my inertial reference frame.

Of course, the trip was not a perfect circle, as Kepler showed the Earth's orbit is an ellipse

with the sun at one of the two focal points. He also figured out the planet goes faster

when it's at perihelion, nearer the sun, than when it's at Aphelian, its furthest distance,

which would explain why summer seems to zip by, except that the seasons are a function of the tilt of the Earth's axis, not its different distances from the sun.

And the Earth rotated 365 and a quarter times during its sweep around the sun.

The trip took 8,76 hours, or 525,960 minutes, or 31,557,600 seconds. Tick-Tock.
