Jeff Bezos Unveils Blue Origin's Prototype of a Lunar Lander
When Robert Heinlein wrote his masterpiece of space age realism, The Man Who Sold the Moon, he had no way of knowing how prescient it would be. Published in 1950, it tells the tale of Delos D. Harriman, the “last of the robber barons,” who is hellbent on being the first man on the moon. Harriman drives himself to the brink of bankruptcy and madness chasing his lunar ambitions, which he feels can’t be left to the bumbling government bureaucracy to handle.

And they had both recently received double lung transplants as a result.The surgeries had gone well. Learn about your ad choices: dovetail.prx.org/ad-choices

China's Scientists Are the New Kids on the Arctic Block
For nearly a century, the Arctic has been a scientific playground for American, Canadian, and European researchers studying everything from magnetic fields to krill populations, as well as documenting rising temperatures and a changing climate. But with China increasingly expressing an interest in all things Arctic, a geopolitical storm is brewing. Traditional boundaries between science, commerce, and the military are melting as fast as the region’s sea ice. Learn about your ad choices: dovetail.prx.org/ad-choices

Calculate the G’s of Using an Ejection Seat to Blast Out of a Jet
I've never been in a situation where I had to choose between the option of crashing in a jet or ejecting from the jet. I hope I would choose the ejection option, since it would more likely lead to a better outcome than crashing. That said, if you look at the ejection systems in modern military aircraft, they look brutal. The acceleration on ejection must be enormous. OK then—let's see if I can measure the acceleration of an ejection seat using video analysis. Learn about your ad choices: dovetail.prx.org/ad-choices

Legendary Haight Street Gets a New, Legal King of Weed
This past Valentine’s Day, Shawn Richard stood before the San Francisco Planning Commission and made the case for why the board should let him open the first cannabis dispensary in the city’s legendary Upper Haight neighborhood. Given the Haight’s legacy as the epicenter of the weed-fueled counterculture movement, his shop would be historically significant. Learn about your ad choices: dovetail.prx.org/ad-choices

SpaceX Is Launching 'Organs on a Chip' to the ISS
Last month, a journal published an n-of-one experiment of unusual origin. It was the study comparing astronaut Scott Kelly’s physiology to that of his Earthbound identical twin brother, Mark. During his time on the International Space Station, Scott gathered reams of data on his own health and took hundreds of samples of his own stool, urine, and blood, for comparison later to those of Mark.

These Super-Precise Clocks Help Weave Together Space And Time
The world’s most precise clock sits on a table in Jun Ye’s lab in Boulder, Colorado. A tangle of electronics, fiber optic cables, and laser beams, the clock is still a prototype, so no one actually uses it to tell time. Ye, who is a physicist at the research institute JILA, and his team have demonstrated that the clock can produce a second with precision in the parts per quintillion—that’s 10-19, some hundred billion times more precise than a quartz wristwatch.

The Grid Might Survive an Electromagnetic Pulse Just Fine
Over the past few years, speculation has risen around whether North Korea or any other nation could detonate a nuclear weapon over the United States that would create an electromagnetic pulse, and knock out all electricity for weeks or months. This doomsday hypothesis has been promoted by a former CIA director , a commission set up by Congress, and a book by newsman Ted Koppel. Learn about your ad choices: dovetail.prx.org/ad-choices

Meet the Pro-Vaxxers Helping to Stave Off the Next Pandemic
Ken Haller is 64, but he vividly remembers having measles when he was 7. And mumps when he was 10. And chickenpox when he was 11, which required him to keep socks on his hands so he wouldn’t gouge his skin from scratching. He still has a faint scar on his nose from one pustule he scratched too intensely. Haller is also a pediatrician who has treated babies who developed meningitis from Haemophilus influenzae (now vaccine-preventable) and became blind—or died.

Fighting Measles, LA Pulls a Classic Move: Quarantine
Hardly anyone actually has measles in Los Angeles (so far; thank goodness). Just five people who passed through the airports, and five residents of the county. Four of those residents are “linked cases,” meaning three got it from one. The problem is, one of those people infected with measles spent some time on the campus of the University of California, Los Angeles. Another one spent an afternoon in a library at Cal State LA.

The Plan to Grab the World's Carbon With Supercharged Plants
In humanity’s battle against man-made climate change, the earth itself provides one of the most important weapons, a natural system that breathes in earth-warming CO2 and exhales oxygen. Yes, I’m talking about plants, engineered by nature itself over the course of millennia to harness the Earth’s natural conditions to turn sunlight and CO2 into oxygen and organic matter. Plants are the key to many climate change-fighting tactics. Learn about your ad choices: dovetail.prx.org/ad-choices

What’s Known About the SpaceX Crew Dragon Accident
During a series of engine tests of SpaceX's Dragon spacecraft this past Saturday, the vehicle experienced what the company has characterized as an "anomaly." Based upon an unauthorized leaked video of the accident, the company was counting down toward a firing of the Dragon's SuperDraco thrusters when the vehicle exploded. SpaceX has not validated the video, but it is consistent with verbal accounts of the failure that have been shared with Ars. Learn about your ad choices: dovetail.prx.org/ad-choices

New York’s Aggressive Climate Law Takes Aim at Skyscrapers
On Thursday, the New York City Council voted into law a sweeping set of rules to fight climate change, a metropolis-scaled version of a Green New Deal. And if the lawmakers and policy wonks who built the bills have their way, they’ll be a model for cities everywhere to cut carbon emissions and save the planet. The Climate Mobilization Act, an omnibus of a half-dozen bills, takes an aggressive posture to reducing carbon emissions from America’s most populous city. Those 8.

China Finds Phone-Wielding Tourists and Telescopes Don't Mesh
If a giant telescope observes the universe, and no one around can take a picture of it, does it really exist? The Five-hundred-meter Aperture Spherical Radio Telescope—located in Guizhou, China—will have to find out. New regulations, put into effect in early April, ban (among other things) cell phones, smart wearables, drones, and digital cameras within 5 kilometers of the dish and impose uncomfortably large fines on those who break the rules.

How the Boston Marathon Messes With Runners to Slow Them Down
The Boston Marathon course looks like it should be fast. You start out in the distant suburb of Hopkinton—elevation 490 feet above sea level—and then cruise steadily downhill until about mile 9. The finish line has an elevation of a mere 10 feet above Boston Harbor. Fans pack the sides cheering you on. The route is pretty straight, west to east, with few 90-degree turns of the sort that slow your momentum. The road is asphalt, which is more forgiving than concrete.

This Tiny Guillotine Decapitates Mosquitoes to Fight Malaria
The idea behind the guillotine is this: If you’re going to execute someone, you may as well do it efficiently and humanely, at least by 18th-century standards. Decapitating the condemned with an ax or sword may take a few swings—unacceptable for carrying out justice in a "civilized" society.

The Fungi Decimating Amphibians Is Worse Than We Thought
For nearly 400 million years, amphibians have led a highly successful double life on Earth, foraging on terra and reproducing in water.
