Researchers have developed a portable water filtration system, powered by bicycle that can be used in disaster zones//. The Nanyang Technological University's (NTU) institute of environmental science and engineering unveiled the unit, consisting of a bicycle coupled with a mechanical pump and a membrane module to filter the water. Believed to be the world's first, NTU exper...GPS Could Help to Identify High Risk Zones
Global positioning systems (GPS) could help identify the places most at risk of devastating earthquakes. Using technology to identify high-hazard 'locked zones' that can spawn giant quakes, researchers attending a meeting in Acapulco, Mexico, held by the American Geophysical Society and several Latin American geophysical associations, claimed that GPS has been used to reveal the lo...Indoor Smoking Bans Creating Unhealthy Outdoor Second-hand Smoke Zones
A new study has found that second-hand smoke from smokers clustered outside establishments, which bans the fag, is posing a health hazard of its own, as there has been an increase of pollutants from it.
