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.

In March 2015, the co-pilot of German Wings Flight 9525 crashed the jet into the French Alps,

killing himself and 149 others. Later on, investigators found out he'd Googled poisons and living

wills, and he'd previously been

treated for severe depression, and yet his mental illness was mostly ignored by Lufthansa,

the airline's parent company.

After the crash, researchers with the Harvard School of Public Health reached out to commercial

pilots worldwide, advertising an anonymous survey about pilot health. Among other topics,

it had a short section on mental health. Investigators found that nearly 13% of the 1800

pilots surveyed met the standard criteria for depression, and 75 of them had had suicidal thoughts

within the last few weeks. The studies in the journal Environmental

Health. A couple caveats here. The researchers didn't clinically diagnose the pilots, and they can't

compare rates of suicidal thoughts in pilots to the rates you'd find among the general population.

That's due to sampling issues. Still, you're probably wondering, should you be worried?

So the answer is no. Alexander Wu, a doctoral candidate in occupational epidemiology.

The data strongly supports the fact that traveling by air is by far the safest form of public

transportation. And our study does not change that fact. So we want everyone to know that for sure.
