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.

Extinction. When species go by-bye forever, we usually blame things like climate change, volcanic eruption, or asteroid impact.

But for the giant flightless birds that once roamed the Australian outback, it was an omelette station what did them in.

A new study finds evidence that about 47,000 years ago, humans helped to wipe out this avian leviathan by collecting and cooking its eggs. The study is in the journal Nature Communications.

Before humans swept over the land down under, animals of enormous proportions were not uncommon.

A two-ton wombat, a thousand-pound kangaroo, and a 500-pound bird, now known as genuineness

newtoni, were spread across the continent.

But most of these so-called megafauna disappeared once humans hit the scene.

Coincidence? Well, it could be, which is why researchers

set out to look for proof that human predation played a role in the demise of genuerness, which only

coincidentally sounds like ginormous. They collected eggshells from hundreds of sites around the country,

and they found that the shell fragments exhibited scorch marks that suggested that the eggs had been purposefully cooked over an open flame,

marks that were not consistent with the eggs getting, say, burned up in a wildfire.

Three different dating methods put the egg's age in the correct era, and thus placed the smoking

gun, or in this case fire pit, directly in the
