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).
Researchers from Xi'an Jiaotong-Liverpool University have found that an impurity present in many industrial pigmentations drastically reduces the strength and longevity of green architectural concrete.
Researchers have discovered a previously unknown repair process in the brain that they hope could be harnessed and enhanced to treat seizure-related brain injuries.
Scientists revealed strong isotope effects in photodissociation of the water isotopologue (HOD) using the Dalian Coherent Light Source.
Mount Sinai researchers have developed a therapeutic agent that shows high effectiveness in vitro at disrupting a biological pathway that helps cancer survive, according to a paper published in Cancer Discovery, a journal of the American Association for Cancer Research, in July.
UC San Diego researchers and their colleagues at the Icahn School of Medicine at Mount Sinai in New York have discovered that spontaneous impulses of dopamine, the neurological messenger known as the brain's "feel good" chemical, occur in the brain of mice. The study found that mice can willfully manipulate these random dopamine pulses for reward.
