How big data is helping farmers save millions

By - October 27, 2014
Data scientists studying crop growth and weather patterns in Colombia have advised rice farmers not to plant crops, saving millions of dollars. The International Center for Tropical Agriculture (CIAT) and the Colombian Rice Growers Federation have developed a computer model that can work out what crops work best under specific weather conditions in certain areas.

Electrodialysis identified as potential way to remove salt from fracking waste water

By - October 26, 2014 2 Pictures
Fracking is a highly controversial and divisive issue. Proponents argue that it could be the biggest energy boom since the Arabian oil fields were opened almost 80 years ago, but this comes at a serious cost to the environment. Among the detrimental effects of the process is that the waste water it produces is over five times saltier than seawater, which is, to put it mildly, not good. A research team led by MIT that has found an economical way of removing salt from fracking waste water that promises to not only reduce pollution, but conserve water as well. Read More

Silicon Valley's latest high-tech gadgetry makes sewage water drinkable

By - October 23, 2014 4 Pictures
Drinking recycled urine may be the stuff of Dune novels, and a drastic response to California’s ongoing drought. But officials in Santa Clara County in the heart of Silicon Valley are hoping its new high-tech purification plant will help residents get past the ick factor and eventually allow treated wastewater to flow through their faucets in a "toilet to tap" scenario. Opened in July, the $72 million Silicon Valley Advanced Water Purification Center is the most advanced such plant in the US, and uses a multi-step system of microfiltration, reverse osmosis and ultraviolet rays to produce water of higher quality than typical drinking water.

IBM "sunflowers" to supply off-grid energy, water, and cooling

By - October 8, 2014 7 Pictures
Looking rather like a 10-meter (33 ft) tall sunflower, IBM's High Concentration PhotoVoltaic Thermal (HCPVT) system concentrates the sun’s radiation over 2,000 times on a single point and then transforms 80 percent of that into usable energy. Using a number of liquid-cooled microchannel receivers, each equipped with an array of multi-junction photovoltaic chips, each HCPVT can produce enough power, water, and cooling to supply several homes.

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

MIT's new cement recipe could cut carbon emissions by more than half

By - September 28, 2014
As one of our most relied upon construction materials, concrete makes a significant contribution to our overall carbon emissions. Calcium-based substances are heated at high temperatures to form the cement, a process that produces carbon dioxide. But by slightly altering the quantities of materials used, scientists from MIT have uncovered a new method of cement mixing that could reduce these emissions by more than half. Read More

Buddhist singing bowls could inspire highly efficient solar cells

By - September 14, 2014
While the unique shape of Buddhist singing bowls is vital to the creation of their signature sound, a researcher from Australia National University (ANU) has used their design as the inspiration for a new breed of solar cells. In completing his PhD at the University of Cambridge, Dr Niraj Lal found that just as the bowls cause sound to resonate, miniaturized versions can be made to interact with light in much the same way, inspiring solar cells better able to capture sunlight.

Newly-discovered waste-eating bacteria could help in nuclear waste disposal

By - September 10, 2014
"Extremophile" bacteria have been found thriving in soil samples from a highly alkaline industrial site in Peak District of England. Although the site is not radioactive, the conditions are similar to the alkaline conditions expected to be found in cement-based radioactive waste sites. The researchers say the capability of the bacteria to thrive in such conditions and feed on isosaccharinic acid (ISA) make it a promising candidate for aiding in nuclear waste disposal. Read More
