Science, Spoken

Credit where credit is due: Evolution has invented a galaxy of clever adaptations, from fish that swim up sea cucumber butts and eat their gonads, to parasites that mind-control their hosts in wildly complex ways. But it’s never dreamed up ion propulsion, a fantastical new way to power robots by accelerating ions instead of burning fuel or spinning rotors. The technology is in very early development, but it could lead to machines that fly like nothing that’s come before them. Learn about your ad choices: dovetail.prx.org/ad-choices

The heat wave that scorched Europe last week felt like a red alert of climate change. Death Valley was cooler than southern France, where temperatures reached a record-breaking 114.6 degrees Fahrenheit. But as the heat broke and returned to relatively temperate 80s, another forewarning emerged. Civilizations need to adapt and protect themselves from extreme heat. More than anyone, the French are aware of just how deadly extreme heat can be. Learn about your ad choices: dovetail.prx.org/ad-choices

Shhhhh. Don’t tell anyone, but Jay Inslee is going to get a presidential debate focused on climate change. Inslee, the governor of Washington state and one of two dozen candidates vying for the Democratic Party’s nomination for president, has been agitating for such a single-topic debate for months. Other candidates have signed onto the idea, and activists within the party have amplified the message. But Tom Perez, chair of the Democratic National Committee, said nuh-uh.

This story originally appeared on Yale Environment 360 and is part of the Climate Desk collaboration. Some 30 miles north of San Diego, along the Pacific Coast, sits the Claude “Bud” Lewis Carlsbad Desalination Plant, the largest effort to turn salt water into fresh water in North America. Each day 100 million gallons of seawater are pushed through semi-permeable membranes to create 50 million gallons of water that is piped to municipal users.

On Wednesday, NASA announced it will send a spacecraft to the surface of Titan, Saturn’s largest moon and one of the leading candidates for finding extraterrestrial microbial life in our solar system. The Dragonfly mission will involve a small, drone-like rotorcraft lander that will be able to fly in small hops across Titan’s surface, covering more distance during its two-year mission than any planetary rover in history.

The Women’s World Cup is in full swing, and today the Americans will face off against France in a battle to advance to the semifinals. This year’s American team is a strong one, both in personality (they are currently engaged in an equal-pay dispute with the US Soccer Federation) and in style—they started the tournament with a 13-0 rout over Thailand.

On Thursday senators tackled the radioactive question of the nation's nuclear waste, this time with a new plan to circumvent the hot-potato politics that doomed Yucca Mountain and other proposals. A combination of new legislation that spreads out the nuclear waste burden and perhaps new technology could offer a new way forward. Everyday, the Department of Energy sends $2.2 million to the nation’s electric utilities to store spent nuclear fuel that has nowhere to go. Learn about your ad choices: dovetail.prx.org/ad-choices

When smoke from California’s deadliest wildfire blew into downtown Sacramento last November, daylight blurred into dusk and the city’s air became among the world’s most polluted. The Camp Fire has long since been extinguished, but the health effects from the tiny particulate matter in the smoke, which penetrates into the lungs and ultimately into the bloodstream, could linger for years.

They used to call it RoboBee—a flying machine half the size of a paperclip that could flap its pair of wings 120 times a second. It was always tethered to a power source, limiting its freedom. Now, though, RoboBee becomes RoboBee X-Wing, as Harvard researchers have added solar cells and an extra pair of wings, freeing the robot to blast off to a galaxy far, far away. Or at least partway across the room, as it can only sustain flight for half a second at the moment, and only indoors. Learn about your ad choices: dovetail.prx.org/ad-choices

Ben Easter was delighted with the way his students were performing. He was especially delighted that a husband had just voted to kill his wife. The couple were both enrolled in the Martian Medical Analogue and Research Simulation, a continuing-education course for medical professionals who wanted to learn about health care in space by pretending to practice medicine in pretend space.
