Cosmic swirly straws: Galaxies fed by funnels of fuel Posted: 24 May 2013 12:48 PM PDT Computer simulations of galaxies growing over billions of years have revealed a likely scenario for how they feed: a cosmic version of swirly straws. The results show that cold gas -- fuel for stars -- spirals into the cores of galaxies along filaments, rapidly making its way to their "guts." Once there, the gas is converted into new stars, and the galaxies bulk up in mass.

Facial-recognition technology proves its mettle Posted: 24 May 2013 11:25 AM PDT In a study that evaluated some of the latest in automatic facial recognition technology, researchers were able to quickly identify one of the Boston Marathon bombing suspects from law enforcement video, an experiment that demonstrated the value of such technology.

Perfect skin: More touchy-feely robots Posted: 24 May 2013 10:43 AM PDT Robots could become a lot more 'sensitive' thanks to new artificial skins and sensor technologies. Leading to better robotic platforms that could one day be used in industry, hospitals and even at home.

Research effort deep underground could sort out cosmic-scale mysteries Posted: 24 May 2013 10:43 AM PDT Scientists have begun delivery of germanium-76 detectors to an underground laboratory in South Dakota in a team research effort that might explain the puzzling imbalance between matter and antimatter generated by the Big Bang.

Detection of the cosmic gamma ray horizon: Measures all the light in the universe since the Big Bang Posted: 24 May 2013 07:46 AM PDT Radiation from all galaxies that ever existed suffuses the universe with a diffuse extragalactic background light (EBL). Measuring the EBL is as fundamental to cosmology as measuring heat from the Big Bang (cosmic microwave background) at radio wavelengths. Researchers describe the best measurement yet of the evolution of the EBL over the past 5 billion years, based on observations from radio waves to gamma rays from NASA spacecraft and ground-based telescopes.

Researchers design photobioreactor to produce biofuel from algae Posted: 24 May 2013 07:41 AM PDT Researchers have patented a new device that allows more efficiently to cultivate microalgae and can be used as raw material for biofuel or for other valuable substances in the agri-food or pharmaceutical industry.

Nano-needles for cells: Tiny needles can force medicine into cells, even when they resist taking it Posted: 24 May 2013 07:40 AM PDT Nano-sized needles developed by researchers in Norway can force medicine into cells, even when the cell membranes offer resistance. The needles will make it easier to study the effects of medicines on cells.

Advanced biological computer developed Posted: 23 May 2013 03:03 PM PDT Using only biomolecules, scientists have developed and constructed an advanced biological transducer, a computing machine capable of manipulating genetic codes, and using the output as new input for subsequent computations.

New filtration material could make petroleum refining cheaper, more efficient Posted: 23 May 2013 11:41 AM PDT A newly synthesized material might provide a dramatically improved method for separating the highest-octane components of gasoline.
