Science, Spoken

Sometimes a bad piece of legislation doesn’t die, it just returns in another form. Call it a zombie bill. In this case the zombie is a bill that morphed into a proposed rule that would upend how the federal government uses science in its decision making. It would allow the US Environmental Protection Agency to pick and choose what science it uses to write legislation on air, water, and toxic pollution that affects human health and the environment.

Sixteen-year-old Swedish activist Greta Thunberg is the symbol of a climate change generation gap, a girl rebuking adults for their inaction in preventing a future apocalypse. Thunberg’s riveting speech at the UN's Climate Action Summit has been viewed more than 2 million times on YouTube, and she was considered a viable contender for the Nobel Peace Prize.

Inside his lab in Israel, Jeff Steinhauer crafts microscopic black holes. These objects are but humble specks, lacking the spaghettifying suction strength of an actual dead star. But Steinhauer, a physicist at the research university Technion, assures me that he’s constructed them mathematically to scale. Zoom in far enough, and you’ll see a miniature event horizon restaging the drama of a true black hole. Learn about your ad choices: dovetail.prx.org/ad-choices

What sort of noise would juggling pins make if they fell three stories off a roof onto the pavement below? For a moment, it seems as if the adults and children gathered for the WIRED 25 Festival atop San Francisco’s Commonwealth Club will find out. But Adam Savage, tossing the three blue, white, and silver pins into the air over and over again, keeps his distance from the roof’s edge and his juggling on point.

Teeming off Hawaii’s famous beaches is a complex web of life—sharks, turtles, seabirds—that relies enormously on tiny larval fish, the food for many species. In their first few weeks of existence the larvae are at the mercy of currents, still too puny to get around on their own, gathering by their millions in surface “slicks” where currents meet.

The air above Earth—especially above California, United States, Earth—might have way more of one particular climate-changing gas in it than anyone thought. And that could actually be good news. The gas is methane, CH4, the main component of natural gas—also a frequent byproduct of oil drilling, agriculture, animal husbandry, garbage decomposition, and farts.

There are no walruses in Iceland, but, at one time, there were hundreds. The timing of the walruses' disappearance suggests that the population's loss may be one of the earliest known examples of humans driving a marine species to local extinction.

In 2017, Stafford Sheehan was a chemist working on artificial photosynthesis, coming up with metal-based catalysts that’d mimic the way living things acquire energy from the Sun. He did not expect to create a martini that could save the planet. Sheehan had an invention, a box that could electrolyze a burst of carbon dioxide and a dose of water. Run all that over a metal catalyst to goose a biochemical reaction, and, presto: renewable fuel made from air. Learn about your ad choices: dovetail.prx.org/ad-choices
