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.

You may have spotted V-shaped squadrons of geese heading south this fall, but for many migrants,

like smaller songbirds, nighttime is the right time when it comes to migration.

The winds are gentler, and darkness helps him avoid airborne attacks.

Of course, darkness also makes

it harder for us to see them, which is where weather radar comes in.

These radars were designed to detect water drops in the air, precipitation in the air.

Jeff Bueller, an ornithologist and aeroecologist at the University of Delaware.

They also detect any other large objects that will reflect back that radio energy,

and it essentially sees insects and bats and birds as large drops of water.

Bueller and his team used three weather surveillance radars

to track migratory birds near the Great Lakes,

and they observed four spring migrations in a row. What they found was, as the track migratory birds near the Great Lakes, and they observed four spring

migrations in a row. What they found was as the night migration ended, and dawn broke, many birds

in flight over the lakes, they turned back, decided to quit for the day, which meant crowded

real estate on the south shore of the lakes, as the birds piled up there to wait out the day.

The study is in the journal of the Ock.
