Hubble spots a bright spark in a nearby spiral galaxy (June 9, 2012) -- A new image, taken by the NASA/ESA Hubble Space Telescope, shows a detailed view of the spiral arms on one side of the galaxy Messier 99. Messier 99 is a so-called grand design spiral, with long, large and clearly defined spiral arms -- giving it a structure somewhat similar to the Milky Way. In recent years, a number of unexplained phenomena in Messier 99 have been studied by astronomers. Among these is the nature of one of the brighter stars visible in this image. ... > full story
Instrument integration begins at Goddard on MMS spacecraft (June 9, 2012) -- The decks have arrived. Engineers working on NASA'S Magnetospheric Multiscale (MMS) mission have started integrating instruments on the first of four instrument decks in a newly fabricated cleanroom at Goddard Space Flight Center in Greenbelt, Md. The MMS mission consists of four identical spacecraft, and each instrument deck will have 25 sensors per spacecraft. ... > full story
Rocket sled tests are technology pathway to safely land humans, habitats and cargo on Mars (June 8, 2012) -- Traveling 300 million miles through deep space to reach the planet Mars is difficult; successfully landing there is even harder. The process of entering the Red Planet's atmosphere and slowing down to land has been described as "six minutes of terror." ... > full story
WISE finds few brown dwarfs close to home (June 8, 2012) -- Astronomers are getting to know the neighbors better. Our sun resides within a spiral arm of our Milky Way galaxy about two-thirds of the way out from the center. It lives in a fairly calm, suburb-like area with an average number of stellar residents. Recently, NASA's Wide-field Infrared Survey Explorer, or WISE, has been turning up a new crowd of stars close to home: the coldest of the brown dwarf family of "failed" stars. ... > full story
Neutrinos sent from CERN to Gran Sasso respect the cosmic speed limit, experiments confirm (June 8, 2012) -- The latest results on the time of flight of neutrinos from CERN to the INFN Gran Sasso Laboratory have just been presented. Four experiments -- Borexino, ICARUS, LVD and OPERA -- all measure a neutrino time of flight consistent with the speed of light. This is at odds with a measurement that the OPERA collaboration put up for scrutiny last September, indicating that the original OPERA measurement can be attributed to a faulty element of the experiment's fibre optic timing system. ... > full story
More people staying connected on vacation (June 8, 2012) -- Scanning smartphones, tablets and laptops is as much a part of vacations as slathering on sunscreen, according to a new study. ... > full story
Engineered robot interacts with live fish (June 8, 2012) -- A bioinspired robot has provided the first experimental evidence that live zebrafish can be influenced by engineered robots. ... > full story
Environmental benefit of biofuels is overestimated, new study reveals (June 8, 2012) -- Two scientists are challenging the currently accepted norms of biofuel production. Calculations of greenhouse gas (GHGs) emissions from bioenergy production are neglecting crucial information that has led to the overestimation of the benefits of biofuels compared to fossil fuels, a new analysis shows. ... > full story
Rubber wood, coconut shells and fabrics tested for use in hybrid composites (June 7, 2012) -- Opening a way to a new hybrid composite, researchers have tested hybrid composites made of rubberwood, coconut shell and textile fabrics (woven cotton and polyester fabrics). ... > full story
Optical materials: Holey gold (June 7, 2012) -- Imaging nanoporous metals with beams of electrons provides deep insights into the unusual optical properties of these materials. ... > full story
Microscopy: A glance from the nanoworld (June 7, 2012) -- A new patterning technique produces a faithful reproduction of grayscale images down to the micrometer level. ... > full story
Groundbreaking new graphene-based MRI contrast agent (June 7, 2012) -- Scientists have developed a new, highly efficacious, potentially safer and more cost effective nanoparticle-based MRI (magnetic resonance imaging) contrast agent for improved disease diagnosis and detection. ... > full story
