Evaporating Water Could Power Almost 70% of The US Electrical Grid

It’s not every day scientists say a new kind of renewable energy could satisfy the majority of our power needs, so when they do, it’s worth leaning in close. In a first-of-its-kind study, researchers have found that energy harvested from the evaporation of water in US lakes and reservoirs could power nearly 70 percent of the nation’s electricity demands, generating a whopping 325 gigawatts of electricity.

Rumors are circulating that scientists have detected gravity waves for the first time ever

Scientists may have detected gravity waves for the first time ever

Physicists have searched for ripples in the fabric of spacetime for nearly 100 years, ever since Albert Einstein’s 1915 theory of relativity predicted they exist. These ripples, called gravitational waves, happen when a massive celestial object suddenly moves, like when a star explodes, or when two massive objects collide, like the merging of two black holes.

There’s a Long-Lost ‘Paleo-River’ Beneath the Sahara Desert Nobody Knew Existed

There’s a Long-Lost ‘Paleo-River’ Beneath the Sahara Desert Nobody Knew Existed

Stretching across 9,400,000 square kilometers of northern Africa-a land area comparable to the entire United States-the Sahara is the largest hot desert in the world, an expanse of shifting sands where only the hardiest wildlife can eke out a living. But new satellite imagery of the Sahara has revealed that the desert wasn’t always such a bone-dry dead zone.
