TB SPEEDTEST: Tuberculosis still kills nearly two million people each year, mainly in developing countries. Current tests are costly and slow, but researchers from the International Centre for Genetic Engineering and Biotechnology in New Delhi in India are developing an electronic nose. The $30 handheld unit is battery operated and works rather like a breathalyser. A person blows into the device, then sensors pick up TB biomarkers and give an almost instant diagnosis. The low cost and ease of use should make it possible to catch more cases of TB in remote areas. Cheap, easy, effective: three winning characteristics. Details at Yahoo News.

SUCKED WET: Ed Linacre's an Australian with a plan to suck water out of the air in deserts and use it for irrigation. His low-tech Airdrop uses a turbine intake to suck air down through underground pipes. Moisture condenses out of the air and collects in a tank. From the tank it can be used to drip feed plants with water. An LCD screen displays tank water levels, pressure strength, solar battery life and system health. The low tech system should make it easy for farmers to install. More at James Dyson Foundation and video here.
