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.

Male humpback whales are the concert singers of the marine world. These ocean giants built out tunes that can be heard perhaps hundreds of miles away. The songs attract friends and

lovers and maybe keep rivals at bay.

And now we learn that humpbacks in different ocean basins, the South Atlantic and the Indian,

on opposite sides of the African continent, share melodies.

The songs are certainly learnt between individuals, so it's thought to be the best example of

horizontal cultural transition, so from's thought to be the best example of horizontal cultural

transition, so from peer to peer rather than from parent to offspring. Melinda Rekdal, Marine

Conservation Scientists with the Wildlife Conservation Society's Ocean Giants Program. The International

Whaling Commission has identified seven distinct humpback whale breeding populations in the southern hemisphere.

These are whales that meet up in the same warm tropical waters each year to mate and give birth.

But when mating season is over, the whales migrate to the Chile polar regions to Gorge on Krill.

Using genetics and photographic surveys of migrating humpbacks,

researchers know that males in these colder feeding areas interact with other males from different

breeding populations. But scientists did not know that this meetup provides the whales with the
