Britain Could Switch Off Airport Radar and Release 5G Spectrum 175

judgecorp writes "Britain is considering switching off air traffic control radar systems and using "passive radar" instead. A two year feasibility study will consider using a network of ground stations which monitor broadcast TV signals and measure echoes from aircraft to determine their location and velocity. The system is not a new idea — early radar experiments used BBC shortwave transmitters as a signal source before antenna technology produced a transceiver suitable for radar — but could now be better than conventional radar thanks to new antenna designs and signal processing techniques. It will also save money and energy by eliminating transmitters — and release spectrum for 5G services."

Do It Yourself Biology Research, Past and Present 108

Harperdog writes "Laura Kahn has a great article about the long and fascinating history of do-it-yourself research, from Darwin and Mendel to present day. From the article: 'Welcome to the new millennium of do-it-yourself (DIY) biology. Advances in technology in the twenty-first century have enabled anybody, with the desire and the disposable income, to build rather sophisticated laboratories in their own homes. Entire communities have even materialized to promote these efforts -- like the thousands of amateur biologists who contribute to DIYbio.org, a website "dedicated to making biology an accessible pursuit for citizen scientists, amateur biologists and biological engineers."'"
