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 60-second science. I'm Christopher Ndallata. Got a minute?

This year, the number of mobile phones on cell networks is expected to surpass the Earth's population.

More people now own cell phones than actually have access to working toilets.

James Meadow, a microbial ecologist at the University of Oregon.

Hidden in the data is the reality that some people work on

their phones on toilets. If that grosses you out, consider this. So it turns out that we're just

really leaky animals. We just, we leave our bacteria everywhere we go. Including, of course,

our phones. Meadow and his colleagues took a census of the bacteria on thumbs and

index fingers of 17 volunteers and on their smartphone touch screens. Overall, they IDed

more than 7,000 types. Looking at just the most common bacteria, those that appear more than

0.1% of the time, they found an 82% similarity between the microbiomes of fingers and

phones, meaning our phones are a pretty good mirror of ourselves, microbially at least. The results

appear in the journal Pure J. We have always been covered in bacteria, and we will always be covered in

bacteria. So the fact that our phones are also covered in bacteria is no reason for concern.

In fact, the researchers say that mobile phones may hold untapped potential as personal microbiome sensors.

App developers, take note.

Thanks for the minute for Scientific American's 60 Second Science.
