Fri, 21 Oct 2016 00:00:00 EDT(Princeton University) Researchers at Princeton University and the University of Texas-Austin found that electrons, when kept at very low temperatures where their quantum behaviors emerge, can spontaneously begin to travel in elliptical paths on the surface of a crystal of bismuth. The strange elliptical orbits correspond to the electrons being in different "valleys" of possible states created by the crystal. The findings could inform further research on a forward-looking strategy for electronics called "valleytronics."
Fri, 21 Oct 2016 00:00:00 EDT(Medical University of South Carolina) Researchers at the Medical University of South Carolina Hollings Cancer Center have discovered a mechanism that confers resistance to drugs used to treat certain types of acute myeloid leukemia. Targeting this pathway with a novel lipid-based therapeutic showed efficacy in a preclinical model of AML. These findings were reported in an article published in the Oct. 13, 2016 issue of Blood.
Fri, 21 Oct 2016 00:00:00 EDT(Carnegie Institution for Science) A group of citizen scientists and professional astronomers, including Carnegie's Jonathan Gagné, joined forces to discover an unusual hunting ground for exoplanets. They found a star surrounded by the oldest known circumstellar disk -- a primordial ring of gas and dust that orbits around a young star and from which planets can form as the material collides and aggregates.
Fri, 21 Oct 2016 00:00:00 EDT(Kansas State University) Kansas State University researchers are part of an international team that has used a molecule's own electrons to scatter the molecule -- a process called mid-infrared laser-induced electron diffraction, or LIED -- and capture snapshots of acetylene as it is breaking apart.
Fri, 21 Oct 2016 00:00:00 EDT(Colorado State University) Colorado State University, home to some of the world's top researchers on methane emissions, will lead a Department of Energy-supported project to analyze emissions from a specific part of the natural gas supply chain: compressor stations. The new project will help scientists develop a more complete picture of overall emissions.
Fri, 21 Oct 2016 00:00:00 EDT(Kent State University) A $450,000 grant from the National Institutes of Health will help biology professor Colleen Novak, Ph.D., from Kent State University's College of Arts and Sciences better understand how the body allocates energy and burns fat.
Fri, 21 Oct 2016 00:00:00 EDT(Sanford Health/Sanford Research) Sanford Health has opened another clinical trial exploring the power of the body's immune system to fight cancer. The immunotherapy trial is focusing on colorectal cancer and involves an investigational drug Sanford is already studying as a potential therapy for other types of cancer.
Fri, 21 Oct 2016 00:00:00 EDT(Goethe University Frankfurt) Chemists at Goethe University have now developed a new catalyst for the activation of hydrogen by introducing boron atoms into a common organic molecule. The process, which was described in the Angewandte Chemie journal, requires only an electron source in addition and should therefore be usable on a broad scale in future.
Fri, 21 Oct 2016 00:00:00 EDT(University of Oxford) Five years ago, the Nobel Prize in Physics was awarded to three astronomers for their discovery, in the late 1990s, that the universe is expanding at an accelerating pace.Now, a team of scientists led by Professor Subir Sarkar of Oxford University's Department of Physics has cast doubt on this standard cosmological concept.
Fri, 21 Oct 2016 00:00:00 EDT(Bangor University) Incentives intended to stimulate the development of more treatments for rare diseases are being exploited to boost the profits of pharmaceutical companies, new research led by Bangor University shows.
Fri, 21 Oct 2016 00:00:00 EDT(Ludwig-Maximilians-Universität München) Physicists at Ludwig-Maximilians-Universitaet (LMU) in Munich have developed a novel nanotool that provides a facile means of characterizing the mechanical properties of biomolecules.
Fri, 21 Oct 2016 00:00:00 EDT(Wiley) Cisplatin is one of the most widely used agents in cancer chemotherapy. It cross-links DNA, which can kill cells. But which part of the genome is more affected, and which is less affected? A Chinese team have now set up a universal, genome-wide assay to detect the specific cisplatin action sites. In the journal Angewandte Chemie they report initial results, which support the notion that the mitochondrial genome is one of cisplatin's main targets.
Fri, 21 Oct 2016 00:00:00 EDT(Moscow Institute of Physics and Technology) Scientists found that treating an ordinary polymer based detector with UV light during manufacturing could turn it into a high bandwidth device with an external quantum efficiency of up to 140,000 percent, as compared to the 30 percent measured before UV treatment.The proposed procedure is cheap, quick, and efficient, and has potential applications in a wide range of systems and devices -- from smartphones to space stations, from environmental monitoring to defense sensing.
Fri, 21 Oct 2016 00:00:00 EDT(University of Southampton) A team of scientists, led by the University of Southampton, have produced a fast nanoscale optical transistor using gold nanoantenna assisted phase transition.
Fri, 21 Oct 2016 00:00:00 EDT(Springer) In 1937, US physicist Isidor Rabi introduced a simple model to describe how atoms emit and absorb particles of light. Until now, this model had still not been completely explained. In a recent paper, physicists have used an exact numerical technique. These findings were recently published in EPJ D by Dr Flottat from the Nice -Sophia Antipolis Non Linear Institute (INLN) in France and colleagues. They confirm previous results obtained with approximate simulation methods.
Fri, 21 Oct 2016 00:00:00 EDT(National University of Singapore) Researchers from the Mechanobiology Institute at the National University of Singapore have revealed the molecular events leading to the regulation of cell growth and proliferation in response to stiffness of the extracellular matrix that surrounds them.
Fri, 21 Oct 2016 00:00:00 EDT(Charité - Universitätsmedizin Berlin) Pathogen epitopes are fragments of bacterial or viral proteins. Nearly a third of all existing human epitopes consist of two different fragments. Known as 'spliced epitopes', these types of epitopes have long been regarded as rare. The fact that they are so highly prevalent might, among other things, explain why the immune system is so highly flexible. Results from this study have been published in the current issue of the journal Science.*
Fri, 21 Oct 2016 00:00:00 EDT(Science China Press) An optical frequency divider, which can accurately divide an optical frequency with a preset arbitrary ratio to several other wavelengths, is demonstrated by scientists in China. During division, the coherence and frequency accuracy of the input light is faithfully transferred to the output light. The demonstrated performance of the optical frequency divider supports frequency division of the most stable and the most accurate optical signals.
Fri, 21 Oct 2016 00:00:00 EDT(Okinawa Institute of Science and Technology (OIST) Graduate University) When treated with an anti-cancer drug, ICRF-193, fission yeast produce an 'arched and snapped' phenotype that may be used to screen for other cancer drugs.
Fri, 21 Oct 2016 00:00:00 EDT(Griffith University) Griffith University is undertaking a major international project to help address community conflict and disruption over wind farms and their implementation in Korea.
Fri, 21 Oct 2016 00:00:00 EDT(Princeton University, Engineering School) Engineers and biologists have for the first time revealed the mechanics of how bacteria build up slimy masses called biofilms, cell by cell. When encased in biofilms in the human body, bacteria are a thousand times less susceptible to antibiotics, making certain infections, such as pneumonia, difficult to treat and potentially lethal.
Fri, 21 Oct 2016 00:00:00 EDT(University of Zurich) Saturday, a parabolic flight is set to take off from Swiss soil for the second time. It will be carrying experiments from various Swiss universities on board to research the effects of zero gravity on biological and physical processes, and test technologies. With this flight, the second from the air force base in Dübendorf within one year, the Swiss Research Station for Zero Gravity initiated by the University of Zurich has got off to a flying start.
