New Satellites Will Use Radio Waves to Spy on Ships and Planes
When a company called HawkEye 360 wanted to test its wares, it gave an employee a strange, deceptive task. While the worker stood in Virginia, he held the kind of transceiver that ships carry to broadcast their GPS locations. Usually such a signal would reveal his true position to a radio receiver, but he’d altered…
A 6-Legged Robot Stares at the Sky to Navigate Like a Desert Ant
In case you’ve been envying the desert ant Cataglyphis fortis lately, don’t. Skittering around the Sahara, the insect endures temperatures so brutal, it can sometimes only manage foraging runs of 15 minutes before it burns to death. Making matters worse, the heat obliterates the pheromone chemical trails that ants typically lay for each other to…
The Risk That Ebola Will Spread to Uganda Is Now ‘Very High’
Ebola is one of those scourges where the mere mention of its name strikes fear: the virus, which kills about half of those it infects and gets passed on through body fluids, is notoriously hard to contain. That means that the best, perhaps only, way to contain an outbreak like the one currently ravaging the…
Get Ready For Gravitational Waves All Day, Every Day
In the sprawling concert venue that is our universe, black holes often collide to produce cosmic cymbal crashes known as gravitational waves. These collisions, along with other astronomical activity that generates these spacetime disturbances, occur frequently enough that a wave should be rippling through some part of the universe at any given moment. But because…
How to Follow New Horizons' Historic Flyby of Ultima Thule
For the past 13 years, NASA's New Horizons spacecraft has been bolting away from the sun at speeds in excess of 31,000 miles per hour, charting a course for the fringes of our solar system. In 2015, it made a close pass of Pluto, returning the highest resolution images of the erstwhile planet the world…
Why Nevada's Execution Drug Cocktail Is So Controversial
A district court judge today halted the execution of Nevada death row prisoner Scott Dozier—a man who has repeatedly expressed his desire to die—hours before he was scheduled to be put to death with an untested injection of three drugs: midazolam, fentanyl, and cisatracurium. The temporary injunction hinges on midazolam, a sedative produced by pharmaceutical…
Cats Bad at Nabbing Rats But Feast on Other Beasts
In the summer of 2017, Michael Parsons found the urban rat haven of his dreams: A Waste Management transfer station—aka a literal trash heap, aka rat paradise—in Brooklyn, New York. For nearly two years, the behavioral ecologist and visiting scholar at Fordham University had been searching for a place to observe the city-dwelling rodents in…

How to Measure Things That Are Astronomically Far Away
If you want to find the size of a basketball, you can use a normal meter stick to measure the diameter. You should get a value of around 0.24 meters. Please don't use inches—they are just harder to deal with. Anyway, you probably aren't using Imperial units since there are only three countries that officially…
The Dismal Science Remains Dismal, Say Scientists
When Hristos Doucouliagos was a young economist in the mid-1990s, he got interested in all the ways economics was wrong about itself—bias, underpowered research, statistical shenanigans. Nobody wanted to hear it. “I’d go to seminars and people would say, ‘You’ll never get this published,’” Doucouliagos, now at Deakin University in Australia, says. “They’d say, ‘this…
