bbc.com has an interesting story about how and why Japan exploded a small bomb on an asteroid.
Nature.com has a great article, How ‘magic angle’ graphene is stirring up physics (Misaligned stacks of the wonder material exhibit superconductivity and other curious properties).
Popular Science put together their list of the 100 greatest innovations of 2018.
After watching the movie Powder and hearing an electrical arc device referred to as Jacob’s Ladder, I looked into it and found this Jacob’s Ladder page on the Popular Science website (where this image comes from). I was familiar with the term in a religious context, but I didn’t know that’s what the name for this device is.
“While his brain was probed by the fMRI, Mingyur (a Buddhist monk) followed the instruction to engage compassion. Once again the minds of everyone watching in the control room felt as though they had stopped. The reason: Mingyur’s brain circuitry for empathy rose to an activity level 700 to 800 times greater than it had been in the rest period just before.”
“Such an extreme increase befuddles science; the intensity with which those states were activated in Mingyur’s brain far exceeds any that had ever been seen in ‘normal’ people. The closest resemblance is for epileptic seizures, but those episodes last brief seconds, not for a full minute. And besides, brains are controlled by seizures, in contrast to Mingyur’s display of intentionally controlling his brain activity.”

This was a good read: Birds can see Earth’s magnetic field, and we finally know how that’s possible.
I saw this quote by Gus Speth on Facebook and Twitter, and wanted to share it here. As Mr. Speth says, the top environmental problems aren’t biodiversity loss, ecosystem collapse, and climate change, they’re selfishness, greed, and apathy (mostly the first two, in my opinion).
Mashable asked astronauts if they think aliens exist. Here’s part of the article I found interesting:
“The math isn’t easy. How many stars are in the universe? Well, that depends on the size of the universe. We’re able to observe the cosmic microwave background (CMB), radiation formed around 400,000 years after the Big Bang. It tells us the observable universe goes back around 14 billion years. But there could be something beyond the CMB, or even other universes contained in a massive ‘multiverse.’”
“Within the constraints of the observable universe, there could be 1,000,000,000,000,000,000,000,000 (or septillion) stars, according to astronomer David Kornreich. (He conceded to Space.com that the number could be a gross underestimate.)”
In case you ever wondered where salt comes from, here’s an article titled, How is salt made?
A high school student won $250,000 for her explanation of relativity, which she titled, Relativity & The Equivalence of Reference Frames. sciencealert.com has the story, and her video.
