This Pollution-Gobbling City Bench Can Absorb as Many Toxins as 275 Trees

Posted on Wednesday, March 21st, 2018 by

This elegant park bench does not just give weary pedestrians a place to rest their feet – it also absorbs as much air pollution as 275 trees, but in a tiny fraction of space. The CityTree bench is the work of Green City Solutions, a Dresden-based design company that creates innovative and environmentally-friendly solutions […]

Farmer-scientists driving social change

Posted on Friday, March 16th, 2018 by

On a brilliant day in July, twenty-some years ago, I stood ankle-deep in the cool mud of a fragrant rice field in central Thailand, listening to the farmers around me discuss the bugs on the plants (were these “satru puut” or “satru thammachat”? pests or natural enemies?), and whether or not the Nitrogen-fixing aquatic Azolla they had […]

A Secret Superpower, Right in Your Backyard

Posted on Tuesday, March 13th, 2018 by

As the verdant hills of Wakanda are secretly enriched with the fictional metal vibranium in “Black Panther,” your average backyard also has hidden superpowers: Its soil can absorb and store a significant amount of carbon from the air, unexpectedly making such green spaces an important asset in the battle against climate change. Backyard soils […]

Environmentally-Friendly Drones Sail Away for Science

Posted on Friday, March 9th, 2018 by

The Mars Rover might be the most famous autonomous vehicle teaming up with human scientists today, but another type of drone is helping researchers here on Earth. The drones are wind-and-solar powered sailboats fitted with cameras, sensors and other research tools, and two of them are set to return in April from their […]

How Crushed Volcanic Rock in Farm Soil Could Help Slow Global Warming

Posted on Wednesday, February 21st, 2018 by

Volcanic plains tend to be fertile farmland. A new study explores how spreading crushed volcanic rock on farms can increase carbon storage and crop yields. Credit: SounderBruce/CC-BY-SA-2.0 Pulverizing volcanic rock and spreading the dust like fertilizer on farm soils could suck billions of tons of carbon from the atmosphere and boost crop yields […]

Rheticus project teams German giants to harvest CO2 in artificial photosynthesis

Posted on Wednesday, January 24th, 2018 by

Germans lead the world in implementing renewable energy infrastructure. But sometimes, there is too much of a good thing: the inability to store excess electricityreduces the efficiency of the renewable energy installations. Meanwhile, carbon dioxide levels continue to rise, and hardly anyone doubts anymore that projects to pull carbon dioxide emissions out of the air will be […]

Solidia Technologies cement cuts emissions and enables concrete that soaks up carbon dioxide too

Posted on Tuesday, January 23rd, 2018 by

Last year, I wrote about how Rutgers University materials science professor Richard Riman was hoping that the low-temperature materials processing technique he helped develop could someday establish a materials-centric version of Silicon Valley. This “Materials Valley” would be centered around businesses that use low-temperature processing to sustainably solidify wide-ranging materials, including ceramics and […]

Scientist Invents Way to Trigger Artificial Photosynthesis That Cleans Air and Produces Fuel

Posted on Sunday, January 14th, 2018 by

A chemistry professor in Florida has just found a way to trigger the process of photosynthesis in a synthetic material, turning greenhouse gases into clean air and producing energy all at the same time. The process has great potential for creating a technology that could significantly reduce greenhouse gases linked to climate change, while […]

How a Forest With More Mammals Stores More Carbon

Posted on Thursday, November 2nd, 2017 by

To the many moral and practical reasons for protecting the creatures with whom we share this blue marble, add one more. They might help Earth safely store more carbon. Writing in the journal Nature Ecology and Evolution, ecologists led by Mar Sobral and José Fragoso of Stanford University describe a three-year-long study of mammals and […]
