Astronauts of the future trekking their way across barren extraterrestrial landscapes may soon do so with less fear or running out of water—or uncomfortably shuffling through their own pee—thanks to a new Dune-inspired urine filtration system. The small, backpack-like device, created by researchers from Cornell University and detailed today in Frontiers in Space Technology, could […]
It’s been over a decade since PopSci last checked in on Minesto’s underwater “kite” turbine technology. Since then, the Swedish green energy startup has made some big strides in their creative approach to generating clean electricity from swimming against the ocean currents. Last week, Minesto announced a major moment for their largest creation. A nearly […]
A Secchi disk is a white circle that helps scientists understand how much phytoplankton is in a body of water. Follow these steps to make and use your own.
Find out if there are PFAS in your drinking water by referring to existing reports or testing your household’s tap water.
The recent Times Square incident was a big inconvenience for commuters and MTA staff. But can cities get better at preventing them?
It’s relatively easy to collect water via harvesting fog—in fact, only a few square meters of meshing can collect upwards of several hundred liters of liquid per day. In many cities, however, these reservoirs of water are often contaminated by atmospheric pollution, thus rendering them unfit for cooking or drinking. Instead of relying on additional, […]
Sports drinks can have a lot of extra sugar and calories you don’t actually need. Better make a DIY electrolyte drink at home.
Learning how to safely cross a river or creek in the backcountry can prevent your hike or camping trip from ending earlier than expected.
It’s been 12 years since Japan’s catastrophic Fukushima Daiichi nuclear plant disaster, and the country is running out of space to contain the fallout. Over 1 million metric tons of radioactive water is currently housed in massive on-site metal tanks—enough to fill around 500 Olympic sized swimming pools—but authorities need to make room for the […]
Scientists found a way to recover 98 percent of all water brought aboard by the space station’s crew—including breath, sweat, and pee.
