Fiber Optic Spanner (Wrench) Developed View Articles
xclr8r writes "A technique to use fiber optics to adjust microscopic particles has been developed. `Rather than an actual physical device that wraps around a cell or other microscopic particle to apply rotational force, the spanner (the British term for a wrench) is created when two laser beams — emitted by a pair of optical fibers — strike opposite sides of the microscopic object, trapping and holding it in place. By slightly offsetting the fibers, the beams can impart a small twisting force, causing the object to rotate in place. It is possible to create rotation along any axis and in any direction, depending on the positioning of the fibers.` Applications of this technology can be used in a number of ways, including cancer research. This technology could be used to actually manipulate DNA. Associate Professor of Physics Samarendra Mohanty states that macroscale applications are a possibility, including `direct conversion of solar energy to mechanical energy,` or possibly using it to `simulate an environment in which photons radiated from the sun could propel the reflective motors in solar sails, a promising future technology for deep-space travel.`" Read more of this story at Slashdot.

New ARPA-E Awards Announced, with Low-Temp Geothermal Development Project at Yale View Articles
On November 28, the Department of Energy (DOE) announced 66 transformational or breakthrough technology projects to receive a total $130 million in a new round of funding through the Advanced Research Projects Agency – Energy (ARPA-E) "OPEN 2012" program. An award for $2,648,074 will be negotiated for a Yale University project with geothermal aspects that could help lower costs for low-temperature development.
Norway`s First Wind Farm on Hold After Lack of Political Support View Articles
Norway put development of its first planned offshore wind farm on hold until further notice, with the company involved citing a lack of political support, a setback in European efforts to boost renewable energy production.
Chemistry of the early universe revealed View Articles
A cloud of hydrogen gas illuminated by the brightest object in the early universe is helping astronomers understand conditions a few hundred million years after the Big Bang. The chemical composition of the cloud indicates that, in this region of space at least, the first generation of stars were still very young at this stage in the universe`s development.
