Still unknown: are the effects due to women drinking more tea than men?

Zero Mass Water's SOURCE device is a rooftop solar device that produces water instead of just electricity.

Because of course you're thinking about water conservation in your yard in the middle of winter.

The recovery of these beleaguered species proves that conservation action works.

SOURCE is a solar-powered and self-contained device capable of harvesting up to 10 liters of clean drinking water per day from the air.

One month is just long enough to break a habit that is seriously compromising your health.

U.S. doctors believes it's a serious public health concern that requires drastic action.

The system will also help reduce the spread of disease in rural villages.

Welcome to my personal dairy dilemma and the weird, convoluted thoughts that keep me up at night.

Researchers conducted the largest controlled study yet of the effects of energy drinks on the heart and blood pressure in healthy adults.

After all, who wouldn't want a glass of "pure glacial water filtered through lava"?

80% of diseases in developing countries trace back to contaminated water. Could a simple ingredient from the kitchen shelf solve the problem?

Clean drinking water is one of our basic human needs, but in many parts of the world, it's also hard to come by. Here's another look at some of the latest concepts for providing clean drinking water.

The Revolve Tap Water Filtration system is an easy way to start choosing to drink tap water over bottled water.

Providing clean water in areas with minimal local resources may be as simple as implementing this ingenious DIY water treatment system.

This little solar powered device can take the guesswork out of SODIS water treatment, showing when the resulting water is safe to drink.

You may love the energy kick from coffee, but too much can be a bad thing. Try some of these greener, cleaner-burning 'fuels' that will wake you up, nourish your body, and keep you going longer.

Beer cans are lined with the stuff, but hey, thats the price you pay for convenience.

What's in that "polymer lining" in every can? A gender-bending hormone that may be really bad for you.

There is a fundamental logical inconsistency here. Either the stuff is bad for you or it isn't.

A bright white antelope with long thin horns, the Arabian oryx is thought to have inspired early stories of unicorns. (Its two horns appear as one when viewed from the side.) And until

The answer is pretty surprising.

When the oft-predicted water wars start, we're going to want this technology on our side. Let's hope it survives the budget wars.

The aquatic moss clears 80 percent of arsenic from a container of water in less than an hour.

The latest video from The Story of Stuff dives into the world of privatized water systems and why this impinges on a basic human right.

This won't solve the climate crisis, but it could help direct air capture of CO2 to scale up.

The Convenience Industrial Complex figured out how sell us something that we don't need at a price that's too high.

A mini video series just released by the National Young Farmers Coalition illustrates the challenges and joys of starting one's own dairy farm.

There isn't much choice, as groundwater reserves are insufficient. But really...is bottled water any worse than this? Four years behind schedule and nearly $80 million over the original budget, the nation's largest sea water desalination facility

Russia reported 11,231 additional cases of the coronavirus disease to bring the country's tally to 177,160 since the outbreak.

Home prices have only fallen nationally once since the Great Depression, and that was after the subprime mortgage crisis and the Great Recession. Now, barely eight years after hitting bottom, and after a mighty recovery, prices are predicted to fall nationally again, down 2-3% this year, according to Zillow.

We are "worried" that humanitarian spaces for refugees may shrink if coronavirus infections within refugee camps rise, says Peter Maurer, president of the International Committee of the Red Cross. He says he also expects ICRC's funding to become "very problematic" with donor countries increasing spending on their own economies.

Market players want to know how much the European Union will provide in additional coronavirus stimulus, but the institution in charge of developing it says it's still under negotiation.

Victoria Falls, on the border of Zimbabwe and Zambia, has slowed down to a trickle after an unprecedented decline in water levels, officials have said. Data from the Zambezi River authority showed water flow at its lowest since 1995, and well under the long-term average. 

The Zambian president, Edgar Lungu, said it was a stark reminder of what climate change is doing to the environment, yet some scientists are cautious about categorically blaming the climate crisis. Harald Kling, a hydrologist at engineering firm Pöyry and a Zambezi River expert, said climate science dealt in decades, not particular years, 'so it’s sometimes difficult to say: this is because of climate change because droughts have always occurred'

The Bank of England has warned the British economy could shrink by 14% this year and unemployment more than double by spring as the coronavirus causes the deepest recession in modern history.

Leaving interest rates on hold at a record low of 0.1% as the economic crisis unfolds, the central bank said economic activity across the country had fallen sharply since the onset of the global health emergency and the lockdown measures to contain its spread.

People who love boozers always said it was the atmosphere, not the alcohol, that attracted them. The lockdown has proved us right

Some forgotten heroes – or mistreated victims, if you prefer – of the coronavirus outbreak are pubs. People who love pubs always said it was the atmosphere, not the alcohol, and people who didn’t love them thought we were just spinning them a line. Now we have proof, because we are drinking as much as we ever did and yet we complain almost constantly.

That debate has ended, anyway, because the people who miss pubs now talk only to each other. We start off complaining about the pub, then segue, almost shyly, into: “Are you managing to drink quite a lot?” “Jesus Christ, you should see the state of my recycling bin. It only got collected two days ago. Today I had to climb into it to compress the cans with my body weight.” “I actually can’t carry as much beer as I want to drink,” said one friend. “One night, I ended up buying a bottle of gin.”
