This Painter Can Even Make Toxic Sludge Look Beautiful

If you didn’t think anything beautiful could come from toxic waste, well, think again. Ohio University art professor John Sabraw and civil engineer Guy Riefler have joined forces and devised a method for extracting iron oxide metals from industrial waste. The extracts can then be turned into vibrant pigments and used to create stunning works of art.


Our Chemicals Are Falling On Remote Parts Of Antarctica In Snow

You probably haven’t heard of “cyclic volatile methylsiloxanes”, but you’ve almost certainly rubbed them into your skin. They’re widely used in lotions and cosmetics to create that smooth, satisfying feel. And now scientists are finding — to their surprise — these chemicals in remote parts of Antarctica.


We're Dumping Eight Million Tonnes Of Plastic Into The Ocean Every Year 

Garbage in the ocean is a big problem, but we never really knew how big. A study published today in Science drops a rough but still astounding estimate: eight million tonnes per year, 20 to 2000 times what we originally thought.


All The Reasons Why You Need To Purify Drinking Water

4 Ideas To Fix Beijing's Smog Airpocalypse, And One That Will Work 

The worst smog of the year so far swept into Beijing this week, coating the city in a grainy, deep grey murk on par with what the city endured in 2013, pictured above (though you’ll see it’s popping up again today). China is trying, hard, to get its air quality problem under control, and is considering some seriously wacky ways to do it. Unfortunately, the only one that will work is also the most difficult.


Wearable Air Quality Sensors Could Help Us All Breathe Easier

Imagine if you could locate the healthiest route for your afternoon jog, the fresh airiest one that would keep you from breathing the pollutants that cars barf out into the atmosphere. It might change every day as these pollutants move around. But you’d be ready, because you’d be wearing an air quality sensor.


Some Of Canada's Lakes Are Turning Into Jelly Thanks To Acid Rain

It’s a real bummer to hear that 150 years of industrialisation wrecked the Earth so bad that it will take thousands to recover. It’s a much bigger bummer to see the situation in real life. That’s exactly what’s happening in a large number of Canada’s lakes, which are turning into jelly thanks to acid rain.


365 Days Of Beijing Pollution In One Megamosaic

Beijing is a great city, especially if you want to develop lung cancer thanks to the overwhelming pollution that shrouds the city most days of the year. This mosaic made by resident Zou Yi during a year of photos from the same window is even more powerful than the usual pictures we are used to.


This Algae Farm Eats Pollution From The Highway Below It

A highway overpass is the last place most of us would think to install a farm. But algae, that wonderful little ecological miracle, is different. Since it consumes sunlight and CO2 and spits out oxygen, places with high emissions are actually the perfect growing area. Which is why this overpass in France has its own algae farm.
