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.

The more astronomers study the heavens, the more they realize our solar system is weird.

So there are a few things that make the solar system kind of strange.

Lauren Weiss, an astrophysicist at the University of Montreal.

One of which is that we have a giant planet, only about 10% of sun-like stars,

have a giant planet. There are probably even fewer that have two giant planets.

In addition to giant Jupiter and lesser giant Saturn, we have tiny mercury, just a bit bigger

than the Earth's moon. So if we're weird, what does a typical solar system look like?

Weiss and her team trained their telescopes on 355 star systems,

known to host a handful of small exoplanets.

And they found that most of the planets within individual star systems

tended to be similar in size.

So if I'm a planet and I'm, say, two times the size of

Earth, my neighbor, the next planet over, is also likely to be two times the size of Earth,

give or take a little bit. And they were strung out at similar distances from each other, too,

like peas in a pod, she says. Compared to that orderly array, our system looks more like,

let's see, if I stick with food, I don't know, like a whole Thanksgiving dinner or something.
