Given the choice between tossing back a dose of medicine and pushing it through your flesh inside a cold, steel needle, most people pick the pill. Convenience, portability, and lack of skin-stabbiness have made pills the most popular way to administer drugs for the better part of medical history. But not all drugs can survive the corrosive, churning trip from the stomach into the intestines and across to the bloodstream. Antibodies, proteins—these molecules are too fragile.

Last Sunday, as much of the country tuned into the Super Bowl, SpaceX CEO Elon Musk and a crew of engineers were gathered in McGregor, Texas, the small city where the company maintains a rocket test site. For a few seconds in the early evening, the sound of a new engine roared across the flatlands. "First firing of Starship Raptor flight engine!” Musk tweeted along with video footage of the test fire.

We already know it’s chilly on the moon. A lunar night lasts 14 Earth days, and its temperatures can dip into a cold so punishing it makes the polar vortex look like a hot tub. But yesterday, China’s space agency announced that the frigidity of the lunar night is even more intense than we’d thought: The country’s Chang’e 4 spacecraft recorded an icy low of –310 degrees Fahrenheit (–190 degrees Celsius).

This story originally appeared on Grist on Jan. 31 and is part of the Climate Desk collaboration. This January should be remembered for its unusual warmth, not its cold. Yes, it’s so cold right now that even hardy Minneapolis is shutting down schools, but even with these few days of extreme cold, Minnesota should end up with a near “normal” month thanks to weeks of unusual warmth. It was in the 70s and 80s as far north as Maryland on New Year’s Day. Learn about your ad choices: dovetail.prx.org/ad-choices

This Sunday, the subreddit /r/superbowl will host a gathering of hoo-ligans. They’ll be fans of the Nocturnal Flying League. Real birds of a feather. Starting at 6 pm ET, the Superb Owl community will kick off an Ask Me Anything with biologist James Duncan, who has spent his entire adult life studying owls and a mere three weeks playing football.

This is not a story about how the polar vortex is bad—bad for the human body, bad for public transportation, bad for virtually everything in its path. This is a story about how one being among us is actually taking advantage of the historic cold snap: Cassie the bipedal robot. While humans suffer through the chill, this trunkless pair of ostrich-like legs is braving the frozen grounds of the University of Michigan, for the good of science.

What beer wants to know is, why do you hate America? How can you just sit in front of the game on Super Bowl Sunday, ice cold domestic lager close to hand, and not consider the future of that great institution? No, not the Super Bowl—the beer. Beer is America. Americans drank 2.9 billion cases in 2017, more than any other alcoholic beverage. It’s true, sales look to be going down, and prices look to be going up. But beer has an even more existential problem. Learn about your ad choices: dovetail.prx.org/ad-choices

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 report today in Science Robotics that they’ve engineered a robot to teach itself the complex physics of Jenga.

Sports teams collect sweat to analyze athlete performance, while companies market sweat replacement drinks and sweat-removal clothing to help keep sprinters, cyclists and tennis players happy. But so far, swimmers have been left high and dry. Today a team of researchers announced they have built a small, flexible, wireless sensor that sticks to a swimmer’s skin, allowing athletes to measure how much they need to drink during a workout or race.

Last Thursday, a shiny new SpaceX Falcon 9 rocket sat perched atop NASA’s historic Pad 39A, at Florida’s Kennedy Space Center, waiting to briefly fire its engines. The exercise was part of a routine pre-launch test. What wasn’t routine was the presence of a Crew Dragon capsule atop the slick black-and-white Falcon.
