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 can thank your parents for your DNA because humans share genes through sexual reproduction, passing DNA from parent to child.

It's known as the vertical transfer of DNA. Now imagine if you could share just one or two bits of your DNA with an unrelated stranger

through a handshake or other incidental contact.

And that stranger inserted your DNA into their genome.

No sex, no offspring either.

That's called the horizontal transfer of DNA.

It's obviously not how humans do it,

but it's a mainstay of single-celled organisms like bacteria,

which use the process to share antibiotic resistance genes, for example.

And now French scientists have found that horizontal DNA transfer could be a lot more common

than we thought in multicellular organisms too, insects in this case,

because by analyzing 195 insect genomes, they found more

than 2,200 cases of this horizontal DNA transfer between unrelated species of flies and
