Science, Spoken

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.

William Peranteau is the guy parents call when they’ve received the kind of bad news that sinks stomachs and wrenches hearts. Sometimes it’s a shadow on an ultrasound or a few base pairs out of place on a prenatal genetic test, revealing that an unborn child has a life-threatening developmental defect.

At the top of the French Pyrenees, not far from the border with Spain, is a virtually pristine clearing, home to snow and a weather station—but mostly feet upon feet of snow. The nearest road closes in the winter. The most substantial town within 60 miles tallies just 9,000 people. Look closely at the landscape, though, and you’ll see the place is covered in plastic.

Some of the wood that burned in the cathedral of Notre Dame in Paris on Monday was put in place in the year 1160. The beams and exterior of the roof over the nave, the long main section of the building, date from between 1220 and 1240. Nearly a millennium ago it was forest; today, after a catastrophe that cuts to the heart of French culture and human history, it’s ash. Learn about your ad choices: dovetail.prx.org/ad-choices

The Falcon Heavy rocket is many things, but “timely” is not one of them. Delay after delay have plagued its development. And this week, the same fate befell its launch schedule. Originally planned to liftoff last Sunday, the Falcon Heavy’s first commercial launch was thrice delayed due to unfavorable weather conditions before it finally left launchpad 39-A at Kennedy Space Center today. The wait was worth it. Learn about your ad choices: dovetail.prx.org/ad-choices

The UK Biobank is the single largest public genetic repository in the world, with samples of the genetic blueprints of half a million Brits standing by for scientific study. But when David Hill, a statistical geneticist at the University of Edinburgh, went poring through that data, he wasn’t looking for a cure for cancer or deeper insights into the biology of aging. Nothing like that. He was trying to figure out why some people make more money than others. Learn about your ad choices: dovetail.prx.org/ad-choices

Last month, the FDA approved esketamine, the nose spray version of ketamine, for treatment-resistant depression. You probably know by now that ketamine is a party drug, but it actually finds far wider use as an anesthetic on the World Health Organization’s list of Essential Medicines. Scientists have a good idea of how exactly it brings about its anesthetic charms, on account of it interacting with certain receptors in the brain.

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.

On Monday, the US Centers for Disease Control and Prevention came out with its latest measles numbers, and let’s be honest, they weren’t great. At least 465 cases across 19 states have been reported nationwide so far this year, including 78 in the last week alone. Nationwide, that means more people have caught the notoriously contagious disease in the past three and a half months than all of last year. Learn about your ad choices: dovetail.prx.org/ad-choices
