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.

Yachtold also partners with nature portfolio to advance gut microbiome science through the global grants for gut health, an investigator-led research program.

In the last few decades, astronomers have discovered thousands of exoplanets orbiting other stars.

Now, scientists want to know what they look like. Do they have oceans, atmospheres?

Researchers have even searched for signs of plant life and the glow of alien city lights, although they haven't

found any yet.

We've moved on from being excited about finding exoplanets to now having to get our kicks

out of characterizing them.

So You Think You Can Science.

Last year, McTeer's advisor challenged her to find something else on exoplanets,

evidence of extraterrestrial mountains, because mountains could offer clues about what's going on

inside these planets.

The way that those form is through the collision of tectonic plates or through lava

building up in the same place over millions of

years. And so that's one of the most exciting things, in my opinion, that can come out of this

project, is actually being able to figure out what's underneath the surface of an exoplanet.

The trick was how to do it. Modern telescopes are powerful, but they can't
