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.
An international team has succeeded in considerably increasing the efficiency for direct solar water splitting with a tandem solar cell whose surfaces have been selectively modified. The new record value is 14 percent and thus tops the previous record of 12.4 percent, broken now for the first time in 17 years.
Scientists have invented a new way to view and create what they are calling 'an electron superhighway' in an organic semiconductor. This approach promises to allow electrons to flow faster and farther - aiding the hunt for flexible electronics, organic solar cells, and other low-cost alternatives to silicon.
The Purdue College of Engineering is using the university's advanced cleanroom at Birck Nanotechnology Center for the laboratory to expand an electrical and computer engineering class that exposes undergraduate students to high-end research.
A new spectroscopy method is bringing researchers closer to understanding - and artificially replicating - the solar water-splitting reaction at the heart of photosynthetic energy production. Understanding the step-by-step mechanism of photosynthesis could lead to methods of producing highly efficient solar energy.
Researchers have found that it is possible to make an electric circuit with a magnetic insulator. This was previously deemed impossible. The circuit is realized using spin waves: wave-like perturbations in the magnetic properties of a material.
