Welcome

We're not The Onion! Not affiliated with them in any way! Not operated by them in any way! All the news here is real!

The Rules

Posts must be:

  1. Links to news stories from...
  2. ...credible sources, with...
  3. ...their original headlines, that...
  4. ...would make people who see the headline think, “That has got to be a story from The Onion, America’s Finest News Source.”

Please also avoid duplicates.

Comments and post content must abide by the server rules for Lemmy.world and generally abstain from trollish, bigoted, or otherwise disruptive behavior that makes this community less fun for everyone.

And that’s basically it!

Scientists have created a wearable sensor that attaches to your underwear and tracks your gut bacteria in real time by measuring the hydrogen gas in your flatulence. And no, that’s not a setup for a joke.

Researchers at the University of Maryland developed the device to solve a problem that has plagued microbiome research for years: how to actually monitor what gut bacteria are doing hour by hour, not just which species are living in there. The answer, it turns out, involves a tiny sensor clipped near your bottom that passively records data while you go about your day.
