(Phys.org) —New research at the University of Arkansas shows that behavior can be predicted and understood in thin films made of materials called relaxors, which can be used in electronic devices.
Mozilla on Thursday teamed with global partners in a push for open mobile standards as it ramps up its efforts to develop smartphones challenging Google and Apple operating systems.
China's first flyby of an asteroid shows that a gigantic space rock which once triggered a doomsday scare is essentially rubble, scientists reported on Thursday.
Maybe it happens tomorrow. Maybe in a billion years. Physicists have long predicted that the universe may one day collapse, and that everything in it will be compressed to a small hard ball. New calculations from physicists at the University of Southern Denmark now confirm this prediction – and they also conclude that the risk of a collapse is even greater than previously thought.
Two teams of researchers, including a scientist from Case Western Reserve University, have announced the discovery of a new species of fossil horse from 4.4 million-year-old fossil-rich deposits in Ethiopia.
A nectar-feeding bat that was thought to eat insects in passing has been discovered to target its moving prey with stealth precision, according to new research by scientists at Queen Mary University of London.
Take one perplexed shopper, add a veritable forest of festive foliage, multiply by some mathematical ingenuity and what have you got? The perfect family Christmas tree.
(Phys.org) —Networks of nanometer-scale machines offer exciting potential applications in medicine, industry, environmental protection and defense, but until now there's been one very small problem: the limited capability of nanoscale antennas fabricated from traditional metallic components.
(Phys.org) —Researchers have found a new way to probe molecules and atoms with an X-ray laser, setting off cascading bursts of light that reveal precise details of what is going on inside. The technique may allow scientists to see details of chemical reactions and home in on the properties of specific elements within complex molecules in a way not possible before.
(Phys.org) —"Insects dominate our world," according to University of Kansas researcher Michael Engel. Thus, anything scientists can learn about the evolution of insects leads to a better grasp of how biology in general has changed over time.
Researchers have discovered an efficient and easy-to-use method for bonding together gels and biological tissues. A team of French researchers has succeeded in obtaining very strong adhesion between two gels by spreading on their surface a solution containing nanoparticles. Until now, there was no entirely satisfactory method of obtaining adhesion between two gels or two biological tissues. Published online in Nature on 11 December 2013, this work could pave the way for numerous medical and industrial applications.
While small-scale horticulture is a relatively recent addition to the human repertoire of food provisioning, hunting has deep evolutionary roots. In practically every society, hunting ability correlates with reproductive success—the better the hunter, the more children he is likely to father.
In an age where 3-D printers are becoming a more and more common tool to make custom designed objects, some researchers are using the technology to manufacture replacement parts for the most customized and unique object of all—the human body.
(Phys.org) —A multi-year study of the Whirlpool galaxy (M51) has changed our understanding of giant molecular clouds, in which stars are born. The new study, which mapped 1,500 such clouds, shows that, instead, they are embedded in a kind of molecular fog, which permeates the whole of the galactic disc. Pressure exerted by this fog is crucial in determining whether or not new stars will form within the clouds. The study, led by Eva Schinnerer from the Max Planck Institute for Astronomy, made extensive use of the millimeter telescopes of IRAM, the Institut de Radioastronomie Millimétrique.
(Phys.org) —Plants rarely get sick in their natural environment. When the threat of infection arises, a quick decision is made about the necessary countermeasures. The course is set by a protein which forms complexes with its partner proteins for this purpose. Jane Parker from the Max Planck Institute for Plant Breeding Research in Cologne and Karsten Niefind from the Institute of Biochemistry at the University of Cologne have, together with colleagues, determined the three-dimensional structure of such a key complex. These molecular close-ups will enable scientists to reach a better understanding of plant immunity in the near future.
(Phys.org) —Big news can spread like wildfire via Twitter, but did you ever think about why certain people choose to retweet? A new study from the W. P. Carey School of Business at Arizona State University shows that if someone doesn't know you well, he or she is actually more likely to retweet something significant you say.
(Phys.org) —By applying pressure to a semiconductor, researchers have been able to transform a semiconductor into a "topological insulator" (TI), an intriguing state of matter in which a material's interior is insulating but its surfaces or edges are conducting with unique electrical properties. This is the first time that researchers have used pressure to gradually "tune" a material into the TI state; as such, the study gives scientists a new route for discovery as they search for TIs that could be used in advanced electronics applications.
(Phys.org) —Some people think that university researchers are so occupied with their laboratories that they've lost sight of the world outside the ivory tower of academia. I would refer those people to Logan Maxwell, a researcher at NC State who has developed a coffee mug that will keep your coffee hot – but not too hot – for hours at a time. And what could be more practical than that?
Researchers from the University of Southampton and the Australian National University report that sea-level rise since the industrial revolution has been fast by natural standards and – at current rates – may reach 80cm above the modern level by 2100 and 2.5 metres by 2200.
A team of researchers from the National University of Singapore (NUS), led by Professor Loh Kian Ping, who heads the Department of Chemistry at the NUS Faculty of Science, has successfully developed an innovative one-step method to grow and transfer high-quality graphene on silicon and other stiff substrates, opening up opportunities for graphene to be used in high-value applications that are currently not technologically feasible.
