N-Fix tech could drastically reduce agricultural fertilizer use

By - July 26, 2013 1 Picture
Synthetic crop fertilizers are a huge source of pollution. This is particularly true when they’re washed from fields (or leach out of them) and enter our waterways. Unfortunately, most commercial crops need the fertilizer, because it provides the nitrogen that they require to survive. Now, however, a scientist at the University of Nottingham has developed what he claims is an environmentally-friendly process, that allows virtually any type of plant to obtain naturally-occurring nitrogen directly from the atmosphere.

California to get America's fastest high-speed rail line

When people grumble about how they think the US isn’t as technologically advanced as it should be, they like to bring up bullet trains – Europe and Asia have them, so why doesn’t America? Well, it’s getting one. Work is starting this summer on a high-speed rail line running from San Francisco to Los Angeles, that will carry a passenger train traveling at over 200 mph (322 km/h).

The Porter School of Environmental Studies highlights sustainable building in Israel

By - July 2, 2013 16 Pictures
A new building at Tel Aviv University features a standalone EcoWall that aims to provide vertical garden space and research facilities for its faculty. The university's Porter School of Environmental Studies (PSES) hopes that its new green building design will not only join the small number of LEED certified buildings in the country, but will also highlight sustainable methodologies for future buildings in Israel.

New material could lead to cheaper, more eco-friendly LEDs

By - June 14, 2013 3 Pictures
LED light bulbs may be more energy-efficient and longer-lived than their incandescent equivalents, but they’re also considerably more expensive to purchase. This is largely because rare earth elements (REEs) are used in their phosphors. There are hazards involved in the mining and processing of REEs, plus China is responsible for almost the entire world’s supply, so they’re becoming increasingly pricey. Now, however, scientists have come up with a plentiful alternative material that they say is much more environmentally friendly, and that should drive down the price of LEDs. Read More

Hathigaon elephant village reclaims land devastated by sand quarrying

By - June 11, 2013 16 Pictures
Hathigaon (or elephant village) is an ongoing low-income housing project by RMA Architects designed to provide a suitable habitat for 100 working elephants and their keepers. The project is located on the foothills of the popular tourist destination of Amber Palace, near Jaipur, India, and sees land once devastated by sand quarrying once again reclaimed for use. Read More

Potentially very-useful "polymer opals" change color when stretched

By - May 31, 2013 1 Picture
Some of the most vividly colored materials in nature, including things like butterfly wings, don’t obtain their color from pigment. Instead, their internal structure reflects light at a given wavelength, producing a specific color. Opals are another example of something that utilizes this effect. In collaboration with Germany’s Fraunhofer Institute for Structural Durability and System Reliability, scientists from the University of Cambridge have now copied the colorful nanostructure of the opal. The result is a flexible, colorful material that won’t fade over time, that changes color when stretched, and that could have many applications. Read More

Non-toxic corn starch could replace cyanide in gold mines

By - May 14, 2013 1 Picture
In the gold-mining process, the precious metal is often extracted from low-grade ore in a technique known as gold cyanidation. As its name suggests, the process utilizes highly-poisonous cyanide, some of which ends up entering the environment in the mines’ tailings. That’s not so good. Scientists at Illinois’ Northwestern University, however, recently announced their discovery of a new gold recovery process that’s based on a non-toxic component of corn starch. Read More

New system could put dead seaweed to use as a source of power

By - May 6, 2013 2 Pictures
When it’s alive and in the ocean, seaweed serves as a habitat, spawning ground and food source for marine life. Once it gets washed ashore, however, it pretty much just rots. Typically, along beaches in tourist areas, that dead seaweed is simply gathered and taken to a landfill. Now, however, researchers from Spain’s University of Alicante have conceived of a new seaweed-removal system that has less environmental impact, and that allows the seaweed to be used as an energy source.
