Using an RNA-powered nanomotor, University of Cincinnati (UC) biomedical engineering researchers have successfully developed an artificial pore able to transmit nanoscale material through a membrane. In a study led by UC biomedical engineering professor Peixuan Guo, PhD, members of the UC team inserted the modified core of a nanomotor, a microscopic biological machine, into a lipid membrane. The resulting channel enabled them to move both single- and double-stranded DNA through the membrane....

UofT researchers have used nanomaterials to develop a microchip sensitive enough to quickly determine the type and severity of a patient's cancer so that the disease can be detected earlier for more effective treatment. Their groundbreaking work, reported Sept. 27 in Nature Nanotechnology heralds an era when sophisticated molecular diagnostics will become commonplace. "This remarkable innovation is an indication that the age of nanomedicine is dawning," says Professor David Naylor, president...

Nanotechnology is viewed favorably, but possible risks should be acknowledged New technologies may change our lives for the better, but sometimes they have risks. Communicating those benefits and risks to the public, and developing regulations to deal with them, can be difficult "” particularly if there's already public opposition to the technology. A new study that provides an overview of research on public perceptions of nanotechnology "” technology on a very, very small scale...

In finally answering an elusive scientific question, researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have shown that the selective placement of strain can alter the electronic phase and its spatial arrangement in correlated electron materials. This unique class of materials is commanding much attention now because they can display properties such as colossal magnetoresistance and high-temperature superconductivity, which are highly coveted...

The burgeoning research fields of nanoscience and nanotechnology are commonly thought to be highly multidisciplinary because they draw on many areas of science and technology to make important advances. Research reported in the September issue of the journal Nature Nanotechnology finds that nanoscience and nanotechnology indeed are highly multidisciplinary "“ but not much more so than other modern disciplines such as medicine or electrical engineering that also draw on multiple areas of...

IBM is using DNA as the inspiration for the structure of future microchips. As chipmakers fight against each other to create increasingly smaller chips cheaply, everyone is being forced to reduce costs. Synthetic DNA nanostructures, or "DNA origami," could be a way to establish an inexpensive framework to construct minute microchips, says a paper published in the journal Nature Nanotechnology. Microchips are placed in computers, cell phones and other kinds of machines. "This is the first...

Groundbreaking results published in the premier scientific journal Nature NanotechnologyThe University of Ghent (UGent) and the nano-electronics research center IMEC demonstrated repulsive and attractive nanophotonic forces, depending on the spatial distribution of the light used. These fundamental research results might have major consequences for telecommunication and optical signal processing.Photon impulse is usually considered to be relatively weak. In our macroscopic world, photons...

As researchers push towards detection of single molecules, single electron spins and the smallest amounts of mass and movement, Yale researchers have demonstrated silicon-based nanocantilevers, smaller than the wavelength of light, that operate on photonic principles eliminating the need for electric transducers and expensive laser setups. The work reported in an April 26 advance online publication of Nature Nanotechnology ushers in a new generation of tools for ultra-sensitive measurements...

A more specific and faster detection of viruses has been identified in new research by Trinity College Dublin's Professor of Physics, Martin Hegner at Trinity College's Center of Research on Adaptive Nanostructures and Nanodevices (CRANN) and an international team of researchers. These findings have been published online in Nature News and will be published in the international peer-reviewed journal Nature Nanotechnology in March. Viruses can be now detected in fluids and their detection is...

Algae is a livid green giveaway of nutrient pollution in a lake. Scientists would love to reproduce that action in tiny particles that would turn different colors if exposed to biological weapons, food spoilage or signs of poor health in the blood. Now, University of Florida engineering researchers have tapped the working parts of cells to clear a major hurdle to creating such "smart dust." The feat, which signifies a new approach to technology known as the "lab on a chip," is to be reported...


Word of the Day
caparison
  • A cloth or covering, more or less ornamented, laid over the saddle or furniture of a horse, especially of a sumpter-horse or horse of state.
  • Clothing, especially sumptuous clothing; equipment; outfit.
  • To cover with a caparison, as a horse.
  • To dress sumptuously; adorn with rich dress.
This word ultimately comes from the Medieval Latin 'cappa,' cloak.
