Scientists have developed a new catalyst that could make lab tests like the PSA much more sensitive. And it may even speed up reactions that neutralize toxic industrial chemicals before they enter lakes and streams.
Researchers have applied super-resolution methods to study the organization of receptors on B lymphocytesAntigen receptors on B lymphocytes sense foreign molecules, such as pathogens or vaccines, and activate the B cells to produce antibodies that protect humans against many diseases.
Researchers developed a nanostructured system capable of protecting the active compounds of juices and nutritional supplements from high temperatures during the pasteurization process, in order to retain their nutritional properties.
Biomedical engineers report a new way to induce human mesenchymal stem cells to differentiate into neuron-like cells: treating them with exosomes from rat-derived progenitor cells. In combination with synthetic nanoparticles now in development, researchers hope to make synthetic exosomes, inducing neuron growth without neural progenitor cells.
A simple mechanism can control the swimming direction of magnetotactic bacteria - a group of bacteria that orient along the earth's magnetic field and are of interest to scientists studying geology, environmental change and more.
Researchers show how natural materials like plant cellulose can self-assemble into surfaces with stunning optical properties - including shiny iridescence and colors that change depending on the humidity.
Researchers have calculated that the Nobel Prize-winning device called a Josephson junction could precisely convert a signal from megahertz to gigahertz - with potential uses in metrology and telecommunications.
An international group of physicists recently presented results of experiments testing a new phenomenon. The results may assist scientists in the creation of an essentially new kind of electronics - Mott transition, or the transition of an insulator to a conductor.
Scientists have imaged how light moves inside an exotic class of matter known as hyperbolic materials. They observed, for the first time, ultraslow pulse propagation and backward propagating waves in deep subwavelength-scale thick slabs of boron nitride - a natural hyperbolic material for infrared light.
Researchers discovered that putting nanotube pillars between sheets of graphene could create hybrid structures with a unique balance of strength, toughness and ductility throughout all three dimensions.
Researchers have developed a technique to observe, in real time, how individual blood components interact and modify advanced nanoparticle therapeutics. The method helps guide the design of future nanoparticles to interact in concert with human blood components, thus avoiding unwanted side effects.
