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.

Volunteers in scientific studies sometimes get compensated. The payment can be cash, a gift card, or something almost worthless.

It's amazing what people will do for a lollipop when they've had a few drinks.

Simon Moore is a professor of public health research at Cardiff University in the UK.

And the lollipops were for people who agreed to blow into a breathalyzer,

while out on a Friday or Saturday night in Wales.

More than 1,800 people agreed to the exchange.

And the scores covered a wide range of alcohol intake.

So that would go from zero upwards.

I think one of the largest scores we had was about 120, which is a near-death experience.

The researchers also gave a subset of volunteers a short survey about drinking habits and health

risks, questions like, how drunk are you right now? And how extreme has your drinking been tonight?

And they found that even very drunk respondents felt relatively more sober if they were surrounded

by even drunker people. In other words, our perception of intoxication and its risks is relative.

So this is the point. As you change context, perceptions will change, although the absolute

level of alcohol in their system doesn't change.

The study is in the journal BMC Public Health.
