Where did today's spiral galaxies come from? (February 6, 2010) -- Using data from the NASA/ESA Hubble Space Telescope, astronomers have created a demographic census of galaxy types and shapes from a time before the Earth and the sun existed, to the present day. The results show that more than half of the present-day spiral galaxies had peculiar shapes only six billion years ago, which, if confirmed, highlights the importance of collisions and mergers in the recent past of many galaxies. It also provides clues for the unique status of our own galaxy. ... > full story
Craters young and old in southern highlands of Mars (February 6, 2010) -- The Mars Express High Resolution Stereo Camera has imaged craters both young and old in a new view of the southern highlands of Mars. ... > full story
Super material will make lighting cheaper and fully recyclable (February 6, 2010) -- With the use of the new super material graphene, Swedish and American researchers have succeeded in producing a new type of lighting component. It is inexpensive to produce and can be fully recycled. ... > full story
New system provides hybrid electric autos with power to spare (February 5, 2010) -- An advancement in hybrid electric vehicle technology is providing powerful benefits beyond transportation. ... > full story
'Artificial pancreas' a step nearer for children with type 1 diabetes (February 5, 2010) -- Scientists have made a significant step towards developing a so-called "artificial pancreas" system for managing type 1 diabetes in children. The team has developed and successfully tested a new algorithm, providing a stepping stone to home testing for the artificial pancreas. ... > full story
Madly mapping the universe (February 5, 2010) -- It takes special software to map the universe from noisy data. Scientists have developed a code called MADmap to do just that for the cosmic microwave background, then posted it on the web for other interested sky mappers. Scientists probing the sky with the PACS instrument aboard the Herschel satellite have adapted MADmap to make spectacular images of the infrared universe. ... > full story
Engineers aim to make air travel greener (February 5, 2010) -- Carbon emissions from air travel could be reduced, thanks to a new collaboration between engineers in the UK and the aerospace industry. The million project will investigate new ways of using composite materials for wing panels in aircraft. The research will be using carbon fibres that are curved within flat plates to produce damage-tolerant, buckle-free structures. ... > full story
Computers that use light instead of electricity? First germanium laser created (February 5, 2010) -- Researchers have demonstrated the first laser built from germanium that can emit wavelengths of light useful for optical communications. It's also the first germanium laser to operate at room temperature. Unlike the materials typically used in lasers, germanium is easy to incorporate into existing processes for manufacturing silicon chips. So the result could prove an important step toward computers that move data -- and maybe even perform calculations -- using light instead of electricity. ... > full story
New material absorbs, conserves oil (February 5, 2010) -- Researchers make new material to clean up oil spills in factories or on the ocean, and conserve the oil. ... > full story
Physicists kill cancer with 'nanobubbles' (February 5, 2010) -- Scientists have discovered a way to use lasers and nanoparticles to identify and treat individual diseased cells with tiny vapor "nanobubbles." In a new study, the scientists described how to use the method to explode nanobubbles and kill cancer cells. In laboratory tests, they showed they could tune these nanobubbles for "theranostics," a combined approach that melds diagnosis and treatment into a single procedure. ... > full story
Video of virus in action shows viruses can spread faster than thought possible (February 5, 2010) -- New video footage of a virus infecting cells is challenging what researchers have long believed about how viruses spread, suggesting that scientists may be able to create new drugs to tackle some viruses. ... > full story
Nano imagining takes turn for the better: Photothermal technique provides new way to track nanoparticles (February 5, 2010) -- Scientists researching how nanomaterials align have found a way to use gold nanorods as orientation sensors by combining their plasmonic properties with polarization imaging techniques. ... > full story
