Sensor Fish show how hydroelectric dams will affect salmon

By - November 8, 2014 6 Pictures
It’s a tough row to hoe for young salmon in the Pacific Northwest as they make their perilous journey from upriver to the ocean. Besides hungry birds and sea lions, the regions many hydroelectric dams and their swirling turbines produce manmade currents and other obstacles that make it challenging for the fish to navigate. But now with the help of an artificial Senor Fish created by the Pacific Northwest National Laboratory (PNNL), existing larger dams and newer, smaller hydroelectric facilities can become more fish-friendly.

The buzz about entomophagy: Is eating insects more than a novelty?

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

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 researchers propose recycling lead from old batteries to produce new solar cells

By - August 18, 2014 1 Picture
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

Boeing begins program to produce aviation biofuel from hybrid tobacco plants

By - August 7, 2014 2 Pictures
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.

Biodegradable fibers as strong as steel made from wood cellulose

By - June 9, 2014 2 Pictures
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

Handheld device detects and analyzes soil contamination within seconds

By - May 21, 2014 3 Pictures
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
