Summary

Learn about how our sun is different from similar stars; how deep sleep literally cleans your brain; and the psychology behind why some psychopaths are serial killers, while others are CEOs.

0:00.0	Hi, you're about to get smarter in just a few minutes with Curiosity Daily from
0:04.8	Curiosity.com. I'm Cody Gough. And I'm Ashley Hamer. Today you learn about how our
0:09.2	sun is different from similar stars, how deep sleep literally cleans your brain, and why some
0:14.9	psychopaths are serial killers and others are CEOs. That's satisfy some curiosity.
0:19.9	The Sun is the most important star in the universe, at least to us here on Earth.
0:26.0	But is there really anything special about it? I mean, objectively?
0:30.0	Researchers compared it to hundreds of similar stars to find out.
0:34.2	And they discovered that, yeah,
0:36.1	there's definitely something unusual
0:38.2	about that big old ball of fire up in the sky.
0:41.2	I don't know if you knew this, but the Sun and other stars have weather, just like we do. But theirs
0:46.2	comes from a powerful magnetic field on their surface. When magnetic activity is at its highest,
0:52.0	the Sun will be marred by dark sunspots and might even shoot
0:55.4	out solar flares, which are usually followed by a devastating coronal mass ejection.
1:01.2	Those are especially scary for modern civilization because they can mess with electronics and cause problems like blackouts.
1:07.0	There's a long-standing disagreement among astronomers about whether the sun is as active as similar stars out there in the universe.
1:16.0	So to settle the debate, these researchers scoured our neighborhood in the universe to find stars
1:21.1	that were about as big and hot as our sun and had similar chemistry and rotational periods.
1:27.0	They found 369.
1:30.0	Then they used data from space telescopes to measure how the star's brightness varied over time.
1:35.0	Since you can't see sunspots on stars that far away, variations in brightness made a good proxy for magnetic activity. The data revealed some interesting results.
1:46.0	First, it is confirmed our son is way less active than the other stars,
