A new study describes a new liquid phase in thin films of a glass-forming molecules. These results demonstrate how these glasses and other similar materials can be fabricated to be denser and more stable, providing a framework for developing new applications and devices through better design.
Soft materials, like skin, behave differently than hard materials when punctured. They provide an unstable resistance that is more difficult to describe and hence predict. Researchers at the University of British Columbia have answered the previously unsolved question of how the mechanics of piercing works on soft materials by studying solutions from the natural world, and have created a mechanical theory that finally predicts the critical force necessary for needle insertion.
A research team in the Korea Institute of Science and Technology(KIST) has announced the development of a thermal-imaging sensor that overcomes the existing problems of price and operating-temperature limitations. The sensor developed in this work can operate at temperatures upto 100 °C without a cooling device and is expected to be more affordable than standard sensors on the market, which would in turn pave the way for its application to smartphones and autonomous vehicles.
Lonely, older adults are nearly twice as likely to use opioids to ease pain and two-and-a-half times more likely to use sedatives and anti-anxiety medications, putting themselves at risk for drug dependency, impaired attention, falls and other accidents, and further cognitive impairment, according to a study by researchers at UC San Francisco.
What The Study Did: Survey data were used to investigate the relationship between loneliness and high-risk medication use in adults older than age 65.
Tokyo, Japan - Researchers from Tokyo Metropolitan University have developed a new technology which allows non-contact manipulation of small objects using sound waves. They used a hemispherical array of ultrasound transducers to generate a 3D acoustic fields which stably trapped and lifted a small polystyrene ball from a reflective surface. Although their technique employs a method similar to laser trapping in biology, adaptable to a wider range of particle sizes and materials.
Long thought of as a generic alarm system, the locus coeruleus may actually be a sophisticated regulator of learning and behavior, according to a new review by MIT researchers. They will test this hypothesis with a new grant.
As reported in Advanced Photonics, researchers from Shanghai University and Fudan University developed a general framework and metadevices for achieving dynamic control of THz wavefronts. Instead of locally controlling the individual meta-atoms in a THz metasurface (e.g., via PIN diode, varactor, etc.), they vary the polarization of a light beam with rotating multilayer cascaded metasurfaces.
A phenomenon known from quantum systems could now make its way into biology: In a new study published in Physical Review X, researchers from the Max Planck Institute for Dynamics and Self-Organization (MPI-DS) in Goettingen show that the notion of topological protection can also apply to biochemical networks. The model which the scientists developed makes the topological toolbox, typically used only to describe quantum systems, now also available to biology.
After gaining world attention by 'unboiling' egg protein, Flinders University scientists have now used an Australian-made novel thin film microfluidic device to manipulate Beta-lactoglobulin (β-lactoglobulin), the major whey protein in cow's, sheep's and other mammals. In the latest application, published in Molecules, College of Science and Engineering experts have combined the capabilities of the VFD with a new form of biosensor called TPE-MI, which is an aggregation-induced emission luminogen (AIEgen).
