To War over Water

Water may be the most abundant molecule on the surface of the Earth, but more than 99% of it is frozen, underground, or too salty to drink.  Only .007% of the planet’s water runs in rivers and lakes, yet this precious amount sustains massive populations worldwide.  Agricultural societies have long gone to war over water,…

Just a Drop to Drink

According to UN Water, “Each of us needs to drink 2 to 4 litres of water every day. But it takes 2000 to 5000 litres of water to produce one person’s daily food.” If that seems like a lot, it is. But it’s funny how much depends on your perspective. A graphic from the USGS…

Two weeks ago (on Earth Day, no less), what is destined to become the biggest ecological disaster in history began as the Deepwater Horizon drilling rig exploded. Situated 50 miles off the Louisiana coast, the well is still gushing oil and the growing slick is now making landfall. While this disaster will continue to unfold…

A Fresh Haul of Sea Life Posts

World Water Day may have come and gone, but ScienceBloggers re still searching the depths of the oceans and the rivers of tropical islands for great new research. Today, Nick Anthis of The Scientific Activist points to the discovery of the first truly anaerobic animal. These microscopic creatures don’t need oxygen to make their home…

When we think of our planet’s water, we usually think of the vast saltwater oceans that contain 97 percent of it. But the other three percent is equally important to ecosystems and to life as we know it: freshwater found above ground in lakes, rivers, and ponds, and underground in aquifers and streams. World Water…

The Buzz: Water, Water Everywhere?

On Friday, NASA scientists confirmed the discovery of water on the moon. Using spectral analysis to determine the composition of the plume resulting from last month’s LCROSS rocket collision, they found more than 100 liters of water. Steinn Sigurðsson on Dynamics of Cats calls the presence of water on the moon “amazing,” but cautions that…

The Buzz: Ocean Plastification

As SciWo explained to daughter Minnow last week in a video on Sciencewomen, lakes, ponds, oceans and other natural bodies of water are as ecologically important as they are beautiful. But the ecological health of many is severely compromised due to widespread pollution, global warming, ocean acidification and other factors. GrrlScientist shed light on the…
