One Map Showing Where the Water Shortages Will Hit

When we talk about a future of drought and water shortages, we're not just talking about the amount of water. We're also talking about how it's distributed — a feature that this world map of the per capita renewable water resources in each country illustrates nicely. » 4/04/14 11:20am 4/04/14 11:20am

Scientists Make Bricks With Sludge Filtered From Arsenic-Laced Water

Arsenic-contaminated water is a massive problem in the developing world. But, even when you filter it out, the toxic sludge that the process produces often gets dumped right back into the water supply. It's tough to dream up a use for arsenic soup, but one research team finally has: They're making bricks out of it. » 3/31/14 5:32pm 3/31/14 5:32pm

Water On Earth: Floods, Droughts And Prediction

Today is World Water Day, a time to think about how water interacts with the environment. Too much water leads to floods and landslides; too little water results in droughts. Better predictions of when either situation is going to occur will reduce risk through better disaster preparation, in turn making everyone safer … » 3/22/14 7:19pm 3/22/14 7:19pm

These Before-And-After Shots Confirm A New Gully Has Formed On Mars!

Check out these before and after snaps of a Martian crater and you'll see something that wasn't there before — and that something is a brand new gully, marked above with the arrow. But anyone hoping that this is even further evidence of flowing water on Mars may be disappointed. » 3/19/14 12:42pm 3/19/14 12:42pm

Astronomers have spotted water plumes on dwarf planet Ceres

We've observed water on Ceres. The largest object in the asteroid belt, you may remember Ceres as the round, rock-ice body that was considered for reclassification as a planet in the midst of Pluto's demotion. Astronomers observed the water in the form of vapor plumes, possibly issuing from volcano-like geysers on the… » 1/22/14 6:00pm 1/22/14 6:00pm

Watch people walk, run and dance on a liquid that thinks it's a solid

Non-Newtonian fluids are seriously strange — a mixture that takes on properties of both a fluid and a solid. Watch as people perform a number of physics-defying tricks on a 2,100 galloon pool of "oobleck." » 1/09/14 6:45am 1/09/14 6:45am

Water Eruptions on Europa Mean that Conditions Are Ripe for Life

Jupiter's moon Europa is covered in a thick layer of ice, but it has a turbulent ocean that lies beneath. Today astronomers announced that new observations show this water is erupting in massive plumes like water volcanoes. It's a discovery that could have serious implications for Europa's potential to harbor life. » 12/12/13 8:00am 12/12/13 8:00am
