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.

The universe is a dark, cold place, but it has a strange region that's even colder than usual.

Seen from Earth, it's an area where the ambient cosmic microwave background light, the leftover thermal energy of the Big Bang, is much

chillier than expected. Now astronomers say they've found in the same part of space a so-called

supervoid, a large area mostly empty of galaxies, and they think the overlap is no coincidence.

The supervoid extends 1.8 billion light years across, making it perhaps the largest

structure known in the cosmos, according to a report in the monthly notices of the Royal Astronomical

Society. The supervoid's relative lack of stuff could have drained energy from light that passed

through it, explaining why the microwave background is

colder there.

Here's how it works.

General relativity tells us that gravity bends space time, causing light to travel a curved

path near massive objects, as if falling into a bowl.

The supervoid, then, with its lack of mass, is akin to a hill.

When light travels up that hill, it loses energy. Normally, it would regain the energy upon exiting the void, that is, when it comes

down the other side of the hill. But because the expansion of space is accelerating, the hill

the light tumbles down is less steep than it was when the
