'The major question is, why would we not eat insects?' (Photo: Shutterstock)

Jiminy Cricket may be able to do more than guide our consciences: he, or his kin, may also provide food security solutions for a growing and hungry world. However, the notion of insects-as-food struggles to find widespread traction amid problems with standardization of food safety standards, government disinterest and only a small body of research. So is there a future for cricket sushi or fried silk worms?  Read More

Mushrooms grown in used diapers help reduce waste volume by up to 80 percent

While the contents of a diaper could easily be considered an environmental hazard by many, disposable diapers themselves pose a more significant problem for the environment. According to the EPA, the average baby will work their way through 8,000 of them before the underwear makes its way to landfill, where it takes centuries to break down. In an effort to reduce the problem, scientists at Mexico's Autonomous Metropolitan University, Azcapotzalco (UAM-A), have turned used diapers to the task of growing mushrooms.  Read More

MIT hopes to turn old lead batteries into new solar cells (Image: Christine Daniloff/MIT)

The world of modern technology is one of out with the old, in with the new. For battery technology, that means the expected demise of lead-acid batteries and replacement by a more efficient, cheaper, and environmentally-friendly alternative. This is good news, but leaves the problem of what to do with all the lead in the batteries currently in use when the time comes to dispose of them? Researchers at MIT have an answer – use it to make solar cells.  Read More

The Treehouse is a high-tech and green office building in Houston's Memorial City, US

Developer MetroNational has unveiled what might just be the coolest Treehouse in Texas. Although not an actual treehouse, it aims to fire the imagination of those inside in the way that a child's treehouse might. It's designed as a space for meetings, collaboration and stimulating ideas.  Read More

Boeing plans to harness South African farmers' knowledge of tobacco growing to produce sus...

As part of the aviation industry’s efforts to use biofuels to drive down its carbon footprint, Boeing has announced a collaboration with South African Airways and SkyNRG to produce aviation fuel from a new, virtually nicotine-free tobacco plant. Test farms are already up and running, with Boeing hoping to use local tobacco growing lands and expertise to produce sustainable biofuel without impacting food-bearing crops or encouraging smoking.  Read More

Fiber made from cellulose claimed to be as strong as steel

A team of researchers working at Stockholm's KTH Royal Institute of Technology claim to have developed a way to make cellulose fibers stronger than steel on a strength-to-weight basis. In what is touted as a world first, the team from the institute's Wallenberg Wood Science Center claim that the new fiber could be used as a biodegradable replacement for many filament materials made today from imperishable substances such as fiberglass, plastic, and metal. And all this from a substance that requires only water, wood cellulose, and common table salt to create it.  Read More

RemScan puts a self-contained soil analyzer in your hand (Photo: ZilteK)

Contamination of soil from petroleum spills is an ongoing problem that threatens to adversely affect the environment and the health of the people in it, so rapid testing of sites is a pressing issue. However, with laboratory samples and results requiring at least a number of days turn around, particularly in remote locations, rapid analysis is not usually possible. RemScan is a self-contained, hand-held hydrocarbon contamination testing device designed to address this problem. Recently released on the US market, the device is capable of testing many hundred samples a day, providing data on the spot, within seconds, and completely without the need of a laboratory.  Read More

EcoCAR 3 tasks students with updating the iconic Chevrolet Camaro muscle car into a hybrid...

For the past 26 years, the US Department of Energy (DOE), in partnership with the North American auto industry, has sponsored Advanced Vehicle Technology Competitions (AVTCs) to provide the next generation of automotive engineers with a practical learning experience. The previous EcoCAR Challenge saw students convert and massage GM Malibus into super-efficient models, and this time for EcoCAR 3, teams are tasked with updating the iconic Chevrolet Camaro muscle car into a hybrid-electric vehicle.  Read More

The solar reactor that was used to turn water and CO2 into jet fuel

In a move that could help address our insatiable thirst for fuel while at the same time help cut CO2 emissions, scientists with the SOLAR-JET (Solar chemical reactor demonstration and Optimization for Long-term Availability of Renewable Jet fuel) project have recently shown that through a multi-step process, concentrated sunlight can be used to convert carbon dioxide into kerosene, which can then be used as jet fuel.  Read More
