Christine Corbett Moran was in Antarctica when she got the news: NASA wanted to interview her, in person, for the next class of astronauts. Moran is a coder and theoretical astrophysicist, and she'd been holed up in the southernmost part of the world for 10 months, studying the echoes of the Big Bang.

Like many people, I enjoy gettinga nice cup of coffee. Not that silly sugary stuff like a double-whip, non-fat, vanilla bean, espresso, iced with a twist of lime. No, I get plain old boring black coffee. But there's a problem: It's almost always too hot to drink right away. When life gives you coffee that's too hot, you must find the best way to cool it. I have two methods to cool off my coffee. Method No.1 is to remove the lid (coffee usually comes with a lidso you don't spill it). Learn about your ad choices: dovetail.prx.org/ad-choices

What generates voltage when you warm it up, push on it, or blow on it? Get your mind out of the gutter. The correct answer is polyvinylidene fluoride, a material NASA researchers have refined for use in morphing aircraft that shapeshift in response to their environment. But wait! There’s more: It can also kickstart the human body’s healing process. Learn about your ad choices: dovetail.prx.org/ad-choices

The protests against the Dakota Access Pipeline at the Standing Rock Indian Reservation in North Dakota are, on the surface, about water quality. The pipeline’s planned route—which closely mirrors the path of the would-be Keystone XL pipeline—goes right through the tribe’s water source. And like Keystone XL (which President Obama vetoed this February), the Dakota Access Pipeline has taken on larger significance as a conduit for worsened global climate change.

Imagine a Where’s Waldo book with nothing butblack and white pictures. Good luck using his candy-stripesweater as a visual cue. Now you know what it’s like trying to find a virus on a greyscale microscopic image. Microbiologists have dealt with this problem for decades, because when things get small, things go dark. Photons, bits of light essential to discerning color, are too clunky to resolve anything much smaller than say, a synapse connecting two neurons.

Last summer, as it sped through the Pluto system, the New Horizons spacecraft only had a few hours to pack its memory banks with as much data about the dwarf planetary system as possible. On October 25, the last few hundred bits of that data finally arrived in one of NASA‘s deep space radio dishes. For posterity’s sake, take a moment and remember that before the flyby—a mere 15 months ago—the dwarf planet was a pixellated blur. Learn about your ad choices: dovetail.prx.org/ad-choices

If we get our way and really put humans on Mars in the coming decades, they’re going to need power. NASA has had concrete plants to send people to the Red Planet since 2010—with target dates in the 2030s, while Elon Musk thinks SpaceX can make it to Mars faster. But no matter who gets there first, the power problem remains. Learn about your ad choices: dovetail.prx.org/ad-choices

Volcanoes have been a persistent feature on Earth since the planet condensed out of the primordial nebula of our solar system. The scale and style of that volcanism has changed dramatically over that 4.5 billion years—heck, after Thera bumped into proto-Earth to form the Moon, we probably had a planet-wide lava lake as the molten Earth coalesced and cooled from the collision. However, we lack much of a record of that tumultuous time beyond a few zircon found in younger sediments. Learn about your ad choices: dovetail.prx.org/ad-choices

Last week, Tanzania planted its first ever genetically modified crop—a drought-resistant white corn hybrid. Government researchers will spend the next two to three years monitoring the plants for safety and effectiveness at growing in perilously dry conditions. It’s a notable milestone, given the nation’s longstanding lack of enthusiasm towards biotechnology. Learn about your ad choices: dovetail.prx.org/ad-choices
