We already know it’s chilly on the moon. A lunar night lasts 14 Earth days, and its temperatures can dip into a cold so punishing it makes the polar vortex look like a hot tub. But yesterday, China’s space agency announced that the frigidity of the lunar night is even more intense than we’d thought:…

Space travel used to be something that only people with the right stuff could experience. But advances in commercial space tourism is changing all of that. Virgin Galactic is registering passengers online. SpaceX announced it would send two lucky passengers around the moon in the next year or two. But space travel is still likely…

In nearly two dozen underground laboratories scattered all over the earth, using vats of liquid or blocks of metal and semiconductors, scientists are looking for evidence of dark matter. Their experiments are getting more complicated, and the search is getting more precise, yet aside from a much-contested signal coming from a lab in Italy, nobody…

This is at least my ninth year of writing about Pi Day—here is my post from 2010. Of course it's called Pi Day because the date, 3/14, is similar to the first three digits of pi (3.1415 …). At this point I've built up a whole library of fun things in honor of Pi Day.…

Every night, an hour before bed, I stash my phone inside a drawer in my living room. Most days I retrieve it the following morning, when I'm heading out the door. It's a simple habit, but one that has helped me reclaim some focus from my smartphone—my personal fix for a growing problem that user…

As flu season nears its annual peak, between 8 million and 9.5 million people in the US have already been sickened by various strains of the respiratory virus, according to new estimates released Friday by federal health officials. That report, from the Centers for Disease Control and Prevention, also estimates that approximately 100,000 people have…

The first time I used a multimeter was in my younger years. I was really into remote-controlled cars—but you couldn't just buy one and start driving. You had to buy a kit and a controller separately and put the whole thing together. My car was powered by a battery and an electric motor instead of…

You don't see this very often—a 350-foot artificial waterfall pouring out of a skyscraper. It looks cool, but it also looks expensive. Gushing water isn't free: You not only have to get the H2O, but you need energy to bring it to the top of the building. This is why the building only runs this…
