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.

When it comes to a guide for your gut, count on YacL.

This is Scientific Americans' 60-second science.

I'm Karen Hopkins. This will just take a minute.

Nothing says overeducated egghead, like a pair of Coke bottle glasses. But even clichés sometimes hit the nerd on the head, because a new study finds that near-sightedness is linked to the

number of years spent in school. The findings can be viewed in the journal Ophthalmology.

In the past century, the prevalence of myopia, science speak for being able to see only what's right in front of

you, has been on the rise, so much so that it can't all be blamed on geeky genes. To nail down

the potential environmental influences, researchers focused on the classroom. They gave eye exams to

nearly 5,000 German subjects in a project called

the Gutenberg Health Study. The researchers found that individuals with 13 years of education were more

myopic than those who didn't get past primary school, and more than half of those with a university

degree could use a set of specs compared to less than a quarter of the folks who quit after

high school or secondary school.

All that learning takes a lot of reading, which itself is associated with nearsightedness.

Or the near-sighted may gravitate toward pursuits easier to see, like hitting the books.

Either way, seems that being a good student may not require great pupils.

Thanks for the minute. For Scientific Americans' 60 Second Science, I'm Karen Hopkins.
