| Posted: 05 Feb 2014 11:38 AM PST A new study reveals that black holes, formed from the first stars in our universe, heated the gas throughout space later than previously thought. They also imprinted a clear signature in radio waves which astronomers can now search for. The study is a major new finding about the origins of the universe.  |
| Posted: 05 Feb 2014 11:38 AM PST Researchers have simulated the formation of the Universe from the Big Bang through the first few hundred million years of its existence. The researchers found that more realistic models of supernova blasts help explain the range of metalicity found in different galaxies. The results of the simulations will assist in guiding the James Webb Space Telescope, set to launch in 2018.  |
| Amputee feels in real-time with bionic hand Posted: 05 Feb 2014 11:37 AM PST Dennis Aabo Sørensen is the first amputee in the world to feel sensory rich information -- in realtime -- with a prosthetic hand wired to nerves in his upper arm. Sørensen could grasp objects intuitively and identify what he was touching while blindfolded.  |
| Pinpointing the brain's arbitrator: Reliability weighed before brain centers given control Posted: 05 Feb 2014 10:32 AM PST Researchers have, for the first time, pinpointed areas of the brain -- the inferior lateral prefrontal cortex and frontopolar cortex -- that seem to serve as an "arbitrator" between two decision-making systems, weighing the reliability of the predictions each makes and then allocating control accordingly.  |
| Quarks in the looking glass: Rare instance of symmetry breaking in electron-quark scattering Posted: 05 Feb 2014 10:32 AM PST A recent experiment has determined how much of the mirror-symmetry breaking in the electron-quark interaction originates from quarks' spin preference in the weak interaction five times more precisely than a previous measurement. The result has also set new limits, in a way complementary to high-energy colliders such as the Large Hadron Collider at CERN, for the energies that researchers would need to access physics beyond the Standard Model.  |
| Ballistic transport in graphene suggests new type of electronic device Posted: 05 Feb 2014 10:29 AM PST Using electrons more like photons could provide the foundation for a new type of electronic device that would capitalize on the ability of graphene to carry electrons with almost no resistance even at room temperature – a property known as ballistic transport.  |
| It's the water: Graphene balloon yields unprecedented images of hydrated protein molecules Posted: 05 Feb 2014 07:33 AM PST An ingenious new technique may open up new vistas for scientists seeking to understand health and disease at the most fundamental level.  |
| Vanadium dioxide research opens door to new, multifunctional spintronic smart sensors Posted: 05 Feb 2014 06:16 AM PST New research findings open the door to smarter sensors by integrating vanadium dioxide onto a silicon chip and using lasers to make the material magnetic. The advance paves the way for multifunctional spintronic smart sensors for use in military applications and next-generation spintronic devices.  |
| Posted: 05 Feb 2014 05:00 AM PST Researchers have investigated the inner structure of soft adhesive materials during the debonding process. Tape, self-adhesive labels, Post-it notes and masking tape all contain soft adhesives. This makes them easy to remove -- a process referred to as debonding. French scientists have studied how soft adhesives work in the hope of facilitating the design of more efficient adhesives.  |
| First affordable hydrogen fuel-cell powered mass transport vehicle under development? Posted: 05 Feb 2014 04:58 AM PST Birmingham City University is set to showcase the concept and design behind what could prove to be the world's first affordable hydrogen fuel-cell powered mass transport vehicle.  |
| The anatomy of an asteroid: Asteroids can have a highly varied internal structure Posted: 05 Feb 2014 04:58 AM PST ESO's New Technology Telescope (NTT) has been used to find the first evidence that asteroids can have a highly varied internal structure. By making exquisitely precise measurements astronomers have found that different parts of the asteroid Itokawa have different densities. As well as revealing secrets about the asteroid's formation, finding out what lies below the surface of asteroids may also shed light on what happens when bodies collide in the Solar System, and provide clues about how planets form.  |
| Novel technique increases detection rate in screening mammography Posted: 04 Feb 2014 04:42 AM PST Digital mammography screening with new photon-counting technique offers high diagnostic performance, according to a new study.  |
| New sensor system improves indoor air quality, makes building ventilation more energy efficient Posted: 04 Feb 2014 04:40 AM PST A research consortium is developing a novel sensor system for monitoring airborne contaminants that will provide high-quality indoor air without the energy losses typically associated with ventilation. Energy consumption levels can be halved as a result. Researchers plan to develop a cost-effective, intelligent ventilation system that will automatically supply fresh air to rooms and indoor spaces as and when needed.  |
| New clues on thermodynamic behavior in small systems Posted: 04 Feb 2014 04:39 AM PST The energy lost in small systems, like nanodevices, can be decisive in order to obtain an optimal functioning of this kind of systems. Under a thermodynamic point of view, the application of the stability theory and classical statistical mechanics to the description of small systems under destabilizing external conditions reveals a constant generation of heat while the system oscillates between two structural configurations or thermodynamic phases.  |
| No room for wrong notes: Analyzing music recordings for plagiarism Posted: 04 Feb 2014 04:39 AM PST Each audio file has its own history. Editing processes such as cutting and compressing leave their own marks, and this is what researchers use to detect manipulated recordings or plagiarized passages of music with the help of special software.  |
| COPD? There's an app for that ... coming soon Posted: 04 Feb 2014 04:38 AM PST A smart phone and a connection to the "Internet of things" could allow people with chronic lung disease to avoid risky areas where environmental conditions, pollution and weather might exacerbate their symptoms.  |
