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.

This is Scientific American's 60-second science. I'm Christopher in Taliatta.

DNA analysis is a staple of crime scenes and crime shows, like HBO's The Night of,

or the old standby, CSI.

So we're just going to get this a DNA lab, have them confirm it is our victim's blood, and then case closed.

And it's not just for crime.

DNA sequencing also helps determine our relationship to Neanderthals and our primate cousins.

Problem is DNA is a relatively fragile molecule.

It doesn't last forever.

What's more sturdy is protein.

So now researchers have

come up with a way to use protein in a similar way to DNA, to link an individual to a piece of

evidence or to determine ethnic background. The protein source these scientists studied was human

hair from 76 individuals of European-American,, African American, and Kenyan descent.

And they determine that the variation of a couple hundred proteins in a person's hair

could be enough to single or out from a group of one million individuals.

The way it works is that proteins are made according to instructions in DNA.

So one individual's genetic variations can result in slightly different proteins being made according to instructions in DNA. So one individual's genetic variations
