Science, Spoken

Last month, the US Department of Agriculture and FDA convened to debate meat: what it is and isn't, and if plant-based or lab-grown products like those made by Impossible Burger and Memphis Meats should be called meat. Lab-grown meat is still months from market, but vegetarian meats already have the poultry and cattle industries in a tizzy. Sales of meat analogues are growing at steady clip of 23 percent a year, nibbling out a decent market share. Learn about your ad choices: dovetail.prx.org/ad-choices

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 lend the room a martian ambience.

Delaney Van Riper was exhausted. It was the summer of 2017 and she’d spent the previous day touring UC Santa Cruz’s cliffside campus, getting her student paperwork in order, and meeting some of her 4,000 fellow incoming Slugs. Now, dressed head-to-toe in sweats, she was ready to nap in the backseat for the ride to her family’s home three hours away in Sacramento. Learn about your ad choices: dovetail.prx.org/ad-choices

The Northern California city of Paradise is gone—the Camp Fire, by far the deadliest and most destructive wildfire in state history, has reduced home after home to ashes. It conjures images of a tsunami of flame tearing through the town, destroying everything in its path. Curiously, though, trees still stand between burned-out homes.

There's really no way to rehearse landing on Mars. You can simulate it, sure, but the most valuable lessons are learned during actual attempts. When things go poorly, those lessons are also the most expensive. The fact is, most missions to Mars don't make it, though NASA has a better track record than most. The agency has executed seven successful touchdowns on the red planet. Learn about your ad choices: dovetail.prx.org/ad-choices

The general rule when developing a new kind of solar technology is to expect progress to be slow. Take silicon solar cells, the most ubiquitous and recognizable form of photovoltaic generations today. When silicon panels were first built in the early 1950s, they could only turn about 6 percent of the light that hit them into electricity. More than 30 years later, that number had inched up to 20 percent, and today—30 years after that—they regularly perform in the mid 20s. Learn about your ad choices: dovetail.prx.org/ad-choices

Electronics often don’t mesh well with flesh and blood. Cochlear implants can irritate the scalp; pacemaker wires dislodge; VR headsets weigh heavily on the face. That’s why, for the past six years, Michael McAlpine has been Frankensteining alternatives. A mechanical engineer at the University of Minnesota, he creates prototypes of bionic body parts with nice, soft components—some of them alive.

The twinkling of a starry night sky is romantic, sure. But for astronomer Dominika Wylezalek, “it’s a nightmare.” That’s because Wylezalek studies galaxies billions of light-years away, and all that finicky glimmering—she’d call it “turbulence”—gets in the way.

To figure out how and when ancient fish first crawled from the ocean onto land, Neil Shubin is about to head to the mountains of Antarctica. Leaving behind family and friends for the upcoming holidays, he and a team of five other scientists and a mountain guide will be camping at the base of a remote mountain range that was a tropical river delta around 385 million years ago.

In my family, Thanksgiving this year has turned into a week-long holiday. Not because we’re all so fanatical about celebrating the violent European colonization of North America, but because it will take us that long to figure out what on Earth to put on the table. In a party of 12 we’ve got a duo of vegetarians, one part-time pollotarian, the recently dairy-avoidant and the long-time spice-averse, plus the seasonal carb-watchers and the one insufferable celery-hater.
