When it comes to water scarcity, the loss of groundwater is like the silent killer: It isn’t as easy to measure or monitor as, say, a shrinking reservoir. We’ve known that many aquifers are overtaxed, but a new report shows we’re draining major aquifers faster than they’re being replenished. Not just in…
11 trillion. 11,000,000,000,000. However, you wrap your brain around it, that number is hard to fathom. But that's how many gallons of water California's three-year drought has sucked from the Earth, according to NASA.
On this dry July day, news about the drought that’s engulfed most of the western United States continues to get worse. But how do we know how extensive the current megadrought is? We actually can measure from the sky, but not in the way you think.
Watching the animation above, it's hard not to get goosebumps when the the clock hits 2012 and the whole United States goes red. That's what it looks like from space when the Earth is parched.
Researchers at Michigan State University have upgraded their autonomous swimming robo-fish named Grace—short for Gliding Robot ACE—with the ability to passively glide through the water, potentially letting it swim forever on a single charge.
Science has long known about the curious gravitational variations of the moon's surface—called mascons—as evidenced by the Doppler shift of radio signals from passing spacecraft. However, researchers are now taking an unprecedented, high-fidelity look at the moon's gravitational field thanks to a pair of washing…
There are plenty of electric bike designs out there, but few (possibly none) can compare to the Grace E-bike. Its CNC-aluminum frame is fitted with eurofighter and Formula One parts, and it has a top speed of 40 mph.
