China Built the World’s Largest Telescope. Then Came the Tourists
“I hope we go inside this golf ball,” Sabrina Stierwalt joked as she and a group of other radio astronomers approached what did, in fact, appear to be a giant golf ball in the middle of China’s new Pingtang Astronomy Town. Stierwalt was a little drunk, a lot full, even more tired. The nighttime scene…
Carbon Capture Is Messy and Fraught—But Might Be Essential
On paper, carbon capture is a simple proposition: Take carbon that we’ve pulled out of the Earth in the form of coal and oil and put into the atmosphere, and pull it out of the atmosphere and put it back in the Earth. It’s like hitting undo on the Industrial Revolution. And scientists can indeed…
Invisible Swarms of Particles Envelop Us All. Come Have a Look
For two and a half years, Michael Snyder began each day by strapping a device to his arm the size and shape of a large matchbox. Gray in color with a nozzle extending from its top, the box went with him everywhere, whether he was traveling abroad, hanging holiday decorations at his home in Palo…
We're Destroying the Sea—But It Could Save Us From Ourselves
The oceans have nourished our species for millennia, but we sure have a funny way of showing our appreciation. Overfishing, pollution, climate change, acidification—I could go on. The sea has always been an indispensable tool for transportation and sustenance, and we’re in danger of breaking that tool beyond repair. Yet the ocean also presents a…
Calling the Caravan's Migrants "Diseased" Is a Classic Xenophobic Move
It would be extraordinarily difficult—impossibly difficult—for any one of the several thousand asylum-seeking refugees in the so-called migrant caravan now on the border between Guatemala and Mexico to have smallpox. A global vaccination campaign eliminated the disease from the world at large in 1980. Yet that’s what a guest on the Fox Business Network1 said…
The Way Superman Picks Up a Building Is a Physics Travesty
You can't really use standard physics principles to explain how Superman can be so strong or fly or have x-ray vision. Pretty much everything he does is impossible. But hey—that's OK. I'm fine with this stretching of reality. It's what makes superheroes interesting. They don't have to be completely realistic to be entertaining. But sometimes…
A Robot Teaches Itself to Play Jenga. But This Is No Game
Click:美丽中国 Global thermonuclear war. The slight possibility that a massive asteroid could boop Earth. Jenga. These are a few of the things that give humans debilitating anxiety. Robots can’t solve any of these problems for us, but one machine can now brave the angst that is the crumbling tower of wooden blocks: Researchers at MIT…
The View From the Control Room: How InSight Landed on Mars
Click:15000PUFFS disposable vape In the morning hours before NASA’s InSight spacecraft entered Mars’s atmosphere, roughly 30 employees of Lockheed Martin gathered in the company’s InSight Mission Support Area, in Denver. They all wore the same red button-down shirt adorned with a mission patch. Someone had taped red plastic over some of the fluorescent lights, to…
Scientists Reconstruct an Object by Photographing Its Shadow
Vivek Goyal isn’t a professional photographer, but he and his colleagues have developed an intriguing party trick: They can capture the image of an object completely out of sight. They demonstrated the trick in a windowless room on the Boston University campus, where Goyal works as an electrical engineering professor. In the room, a flatscreen…
