Science, Spoken

“I choose to go to the moon.” Those were among the first words uttered on stage Monday night by Yusaku Maezawa, the mysterious passenger whose existence SpaceX CEO Elon Musk had teased on Twitter last week. Maezawa, a Japanese retail entrepreneur and art collector, stood before a small crowd at SpaceX headquarters and announced that he had also secured tickets for several companions on this week-long journey into space: a half-dozen artists that he will later select and invite along.

Astronomers have finally found the last of the missing universe. It’s been hiding since the mid-1990s, when researchers decided to inventory all the “ordinary” matter in the cosmos—stars and planets and gas, anything made out of atomic parts. (This isn’t “dark matter,” which remains a wholly separate enigma.) They had a pretty good idea of how much should be out there, based on theoretical studies of how matter was created during the Big Bang. Learn about your ad choices: dovetail.prx.org/ad-choices

Writing about climate change is an exercise in managed insanity. The human mind isn’t equipped to parse a crisis—the greatest in the history of our species—of such complexity and urgency and darkness. With record-breaking superstorms ravaging coastlines at a regular clip, it’s hard to feel good about the impact that Homo sapiens has had on our leafy, temperate, Goldilocks planet.

The map looks terrifyingly unfamiliar. Not because of the outlines of the continents; those are comforting in their hooks, tails, splotches, and whorls. It’s the storms. Across the globe’s tropics right now, seven superstorms are swirling over oceans. Hurricane Florence is butting into the Carolinas on North America’s southeastern coast. Tropical storms Helene, Isaac, and Joyce are hovering over the Atlantic like jets stacked on approach to Charlotte. Learn about your ad choices: dovetail.prx.org/ad-choices

Nothing against the countryside, which is lovely, but cities are where things happen. They are magnets for trade, and they're where cultures meet. They're also where more than half the world’s population lives, a number that will only continue to grow. Cities are also now serving as a unique testbed for responses to climate change—bolstering public transportation, erecting more efficient buildings, deploying renewable energy.

Respect where respect is due: we humans may be mighty, but there’s still a foe that regularly dodges our best efforts to kill it: the fruit fly. Over millennia of evolution, fruit flies have adapted to burn their pursuers with enviable agility. Now researchers have built a robotic doppelganger that can twist and bank with astonishing speed. With two pairs of wings beating 17 times a second, it has a wingspan of over a foot and weighs just an ounce. Learn about your ad choices: dovetail.prx.org/ad-choices

Space travel used to be something that only people with the right stuff could experience. But advances in commercial space tourism is changing all of that. Virgin Galactic is registering passengers online. SpaceX announced it would send two lucky passengers around the moon in the next year or two. But space travel is still likely going to cater to a select few, in this case, people with the right amount of money. Virgin Galactic is currently pricing initial flights at $250,000.

Sometimes it's right on the box of rice mix—the high altitude version of cooking instructions. Usually this means that your rice will have to cook a little bit longer if you are in Denver or at the top of Mount Everest. Of course that's just a joke. No one cooks rice at the top of Everest. But why are the instructions even different? Why does it matter where you cook? The answer has to do with boiling water. Go ask some people on the street about the boiling temperature of water.

An entire summer’s worth of rain has fallen across a broad swath of the Midwest in recent days. The resulting record floods have wrecked homes and altered the paths of rivers, in one case destroying a waterfall in Minnesota. The worst-affected region, southwest Wisconsin, has received more than 20 inches of rain in 15 days– more than it usually gets in six months. Learn about your ad choices: dovetail.prx.org/ad-choices

Every night, an hour before bed, I stash my phone inside a drawer in my living room. Most days I retrieve it the following morning, when I'm heading out the door. It's a simple habit, but one that has helped me reclaim some focus from my smartphone—my personal fix for a growing problem that user experience researchers at Google recently called an "attention crisis." Outside the house, though, it's a different story: My phone rarely leaves my side. Learn about your ad choices: dovetail.prx.org/ad-choices
