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.

You probably don't think of scientific or medical instruments as the kind of instruments that actually make music.

But now researchers have built a scientific instrument specifically designed to detect counterfeit medications through sound.

Someone even made the comparison that we're making a scale in the sense that it measures mass,

you know, but it also plays scales in the sense that it makes musical notes.

William Grover, a bioengineer at UC Riverside.

He and his team took inspiration from the African musical instrument called the Mbira.

It has metal tines which resonate

over a small wooden board when you pluck them. Instead of tines, Grover's instrument uses a hollow

metal tube. Just load a sample of medication inside and it changes the tone of the instrument.

And so a sample that's more dense creates a lower note.

A sample that's less dense creates a higher note in terms of pitch.

For example, here's the tube with air inside.

Here it is again with water inside.

It's denser, so the pitch is lower.

The World Health Organization reckons about 10% of the medications in low-in-middle-income countries are fakes, sometimes dangerous ones.

So the idea here is to fill the tube with a sample that's known to be safe, like cough syrup from a reputable source,
