Scientists running the ATLAS experiment at the Large Hadron Collider report the first evidence of a process that can be used to test the mechanism by which the recently discovered Higgs particle imparts mass to other fundamental particles. More rare than the production of the Higgs itself, this process also provides a new stringent test of the Standard Model of particle physics.
Lithium-ion batteries could benefit from a theoretical model created at Rice Univ. and Lawrence Livermore National Laboratory that predicts how carbon components will perform as electrodes. The model is based on intrinsic electronic characteristics of materials used as battery anodes. These include the material’s quantum capacitance and the material’s absolute Fermi level.
Last year, Massachusetts Institute of Technology researchers discovered that when water droplets spontaneously jump away from superhydrophobic surfaces during condensation, they can gain electric charge in the process. Now, the same team has demonstrated that this process can generate small amounts of electricity that might be used to power electronic devices.
The rate of Alzheimer's disease and other dementias is falling in the U.S. and some other rich countries—good news about an epidemic that is still growing simply because more people are living to an old age, new studies show. An American over age 60 today has a 44% lower chance of developing dementia than a similar-aged person did roughly 30 years ago, the longest study of these trends in the U.S. concluded.
A research team in Illinois has built a new type of tunable nanoscale antenna that could facilitate optomechanical systems that actuate mechanical motion through plasmonic field enhancements. The team’s fabrication process shows for the first time an innovative way of fabricating plasmonic nanoantenna structures under a scanning electron microscope, which avoids complications from conventional lithography techniques.
Firms buy specific keywords, including competitors’ brand names, on search engines such as Google or Bing to reach consumers searching for those words. Online advertisements employing such keywords are called search ads. This practice can backfire, however. A new study shows that any large difference in reputation between the two brand names is further magnified in the minds of consumers.
Leica Microsystems has introduced the new Leica Planapo 2.0x CORR objective for the Leica M series stereo microscope, specifically for the use with specimens immersed in aqueous solution. With this objective, users can obtain pin sharp visualization of specimens with up to a 5 mm water column between the specimen and the objective.
PerkinElmer, Inc. has announced the launch of the new LabChip GX Touch and GXII Touch automated electrophoresis systems. The LabChip platform’s key feature is automation of conventional gel electrophoresis, eliminating the need for manual sample preparation and allowing precise nucleic acid quantification and protein characterization.
Developmental processes in all living organisms are controlled by genes. At the same time there is a continuous metabolism taking place. Recent research in Austria has analyzed this interaction in flowering plants. For the first time, changes in metabolism were linked to 3-D morphometric data using micro-computed tomography (micro-CT) for the first time.
The discovery of buckyballs helped usher in the nanotechnology era. Now, researchers from Brown Univ. and colleagues from China have shown that boron, carbon’s neighbor on the periodic table, can form a cage-like molecule similar to the buckyball. Until now, such a boron structure had only been a theoretical speculation.
The creators of a unique kit containing 3-D printed anatomical body parts say it will revolutionize medical education and training, especially in countries where cadaver use is problematic. The “3D Printed Anatomy Series”, developed by experts in Australia, is thought to be the first commercially available resource of its kind. The kit contains no human tissue, yet it provides all the major parts of the body required to teach anatomy.
Scientists in Israel have recently constructed, for the first time, a photonic router that enables routing of single photons by single photons. At the core of the device is an atom that can switch between two states. The state is set just by sending a single particle of light, or photon, from the right or the left via an optical fiber. The innovation could help overcome difficulties in building quantum computers.
A cheap, portable, microchip-based test for diagnosing type-1 diabetes could speed up diagnosis and enable studies of how the disease develops. Handheld microchips distinguish between the two main forms of diabetes mellitus, which are both characterized by high blood-sugar levels but have different causes. Until now, making the distinction has required a slow, expensive test available only in sophisticated healthcare settings.
Marilyn Minus, a materials expert and assistant professor at Northeastern Univ., is exploring directed self-assembly methods using carbon nanotubes and polymer solutions. So far, she’s used the approach to develop a polymer composite material that is stronger than Kevlar yet much lighter and less expensive. Minus is now expanding this work to incorporate more polymer classes: flame retardant materials and biological molecules.
Rutgers Univ. researchers have developed a technology that could overcome a major cost barrier to make clean-burning hydrogen fuel. The new catalyst is based on carbon nanotubes and may rival cost-prohibitive platinum for reactions that split water into hydrogen and oxygen.
