This $8 Trillion Coronavirus Mistake Could Kill 100%, w Stephen Fry.
The first three minutes talk about the danger of lab experiments on viruses. Then the video talks about other ways humans could destroy themselves.

Risking My Life To Settle A Physics Debate
I forget who said it -- several years ago -- but went something like:
"Sure they made it work in practice, but can they make it work in theory?"

What exactly are mushrooms? What are they made of? They're not vegetables?
I am not thrilled with the idea of eating a fungus. They are pretty good on pizza. While I was in college I would occasionally eat deep-fried mushrooms, but it has been at least 35 years since I last did that. Why eat deep-fried mushrooms when you could eat french fries or onion rings?
The bulk of the information is in the first half of the video.

NASA traces source of mysterious fast radio bursts sending signals to Earth - CBS News
Don't panic, but mysterious sources have been sending radio signals to Earth for years. Now, scientists have tracked down some of their origins — and they were surprised by what they found.
And no, it's still not aliens.

Trillions of Rogue Planets Hidden In Our Galaxy With One Very Close
I wouldn't necessarily watch the video, but I find it interesting that there are all these Rogue Planets moving around the galaxy. It would be very unlikely, but if one were to pass through the orbital plane of our solar system, then it could alter the orbit of one or more planets. There is a remote chance that this has happened before. Sometimes they talk about how planets get ejected from solar systems by massive objects.
Fortunately, the galaxy is very big, thus reducing the chance of having an encounter like this.
The 3 Brain Types and What They Mean
I wanted to know what the three brain types are, but first, he spends 18 minutes talking about IQ and intelligence.

What's the truth about antigravity?
https://www.youtube.com/watch?v=_SGnOeGZUAU
I had a manager who believed that since magnetism is a dipole, that we should also have positive and negative gravity. The problem with this idea is that it is likely a bad analogy. I have seen videos stating that gravity is not a force, but a by-product of moving through curved spacetime. (I am still skeptical of the "spacetime" concept, thinking of it only as a useful and accurate model.)
Anti-matter is simply matter that has an opposite charge. There is no reason to think that it would be affected in a different way by gravity. If it were, I think that we would have to rewrite the laws of physics.

Betelgeuse Is Not How You'd Imagine
Sometime in the next million years, and nobody knows when, Betelgeuse will explode.

Dark Matter's Last Stand - Scientific American
Scientists are fond of saying negative results are just as important as positive results, but after several decades of not finding something, researchers can be forgiven for feeling impatient. Back in the 1990s, experiments began trying to detect the particles that make up dark matter, the ubiquitous yet untouchable invisible material that apparently fills the cosmos. Since then, physicists have found more and more evidence that dark matter is real but not a single sign of the stuff itself.

AMAZING INVENTIONS THAT ARE NEXT LEVEL!
Not sure how many of these are useful. Some inventions can be cool but not cost-effective. This reminds me of looking at magazines in the 1970s where they predicted that we would have nuclear-powered cars by the year 2000.
