General Motors and Segway have teamed together to build the PUMA (Personal Urban Mobility and Accessibility). The prototype runs on a lithium battery and was designed to be a fast, safe, inexpensive and clean alternative to cars. The Planck research satellite has been developed to measure very weak background cosmic radiation, the last vestiges of the Big Bang at the beginning of time. Dolphins emit an extremely complex stream of sounds. Now, a British scientist claims he is close to deciphering their special language, with the help of sand, glass and a violin bow. We look at the remote mining town of White Cliffs, Australia, and its relics from the days it relied on solar power before it was connected to the grid. In Britain, efforts to generate power by harnessing an estuary’s tidal power are creating controversy because of the expected negative impact on wildlife. Meanwhile, advances in carbon capture technology may help keep carbon dioxide and other greenhouse gasses out of the atmosphere.
