Solar-powered, waterproof mobile phone:
NTT DoCoMo has developed a solar-powered, water-proof mobile phone called Solar Hybrid (DoCoMo STYLE series SH-08A). The Solar Hybrid can be recharged with sunlight as well as electricity. Even if the battery has completely lost ist charge, just 10 minutes of solar recharging via a panel on the phone' s body provides approximately one minute of talk time
The handset comes with an 8 megapixel CCD camera, and fits waterproof body is resistant to water sprays from all directions and submersible to depths up to one met
Bacterial computers:
Researchers in the US have developed bacterial computers that can revolutionise genetic resea
rch. The research team, including scientists from Missouri Western State University and Davidson College in North Carolina, USA, engineered the DNA of Escherichia coli bacteria and created bacterial computers capable of solving a classic mathematical problem known as the Hamiltonian Path problem.The Hamiltonian Path problem asks whether there is a route in network from a beginning node to an ending node, visiting each node exactly once. The researchers modified the genetic circuitry of the bacteria to enable them to find a Haliltonian path in a three node graph. Bacteria that successfully solved the problem reported their success by fluorescing both red and green, resulting in yellow colonies.
Mini projector for phones:
Researchers at the Fraunhofer Institute for Applied Optics have developed a
mini projector that promises to cut down on the flab and the large power requirements of existing phone projection technologies. The new system uses a lens system to project light and images generated by a low-power organic light-emitting diode (OLED). Use of the OLED means there is no need for a separate light source and the lens system ensures decent image reproduction.
