Researchers from North Carolina State Univ. have developed new technology and techniques for transmitting power wirelessly from a stationary source to a mobile receiver—moving engineers closer to their goal of creating highway “stations” that can recharge electric vehicles wirelessly as the vehicles drive by.
It may sound like chasing rainbows: Detecting flashes of light and energy that are invisible to the human eye and last only for a trillionth of an eye-blink. These flashes hold clues to the nature of exotic subatomic particles, important biological proteins and massive space objects alike.To reveal new details about science at these extremes, a team of scientists is designing intricate signal-processing chips known as ASICs.
When you squeeze atoms, you don’t get atom juice. You get magnets. According to a new theory by Rice Univ. scientists, imperfections in certain 2-D materials create the conditions by which nanoscale magnetic fields arise. Calculations by the laboratory of Rice theoretical physicist Boris Yakobson show these imperfections, called grain boundaries, in 2-D semiconducting materials known as dichalcogenides can be magnetic.
A team of scientists reports that a small-molecule compound showed significant success in controlling the infectivity and spread of three polyomaviruses in human cell cultures. To date there has been no medicine approved to treat such viruses, which prey on transplant recipients, people with HIV and others whose immune systems have been weakened.
Researchers at Rice Univ., Baylor College of Medicine and the Univ. of Texas at Austin are working together to create new statistical tools that can find clues about cancer that are hidden like needles in enormous haystacks of raw data.
A class of drugs used to treat parasitic infections such as malaria may also be useful in treating cancers and immune-related diseases, a new Washington State Univ.-led study has found. Researchers discovered that simple modifications to the drug furamidine have a major impact on its ability to affect specific human proteins involved in the on-off switches of certain genes.
Invisibility cloaking is no longer the stuff of science fiction: Two researchers at the Univ. of Toronto have demonstrated an effective invisibility cloak that is thin, scalable and adaptive to different objects. The team designed and tested a new approach to cloaking—by surrounding an object with small antennas that collectively radiate an electromagnetic field. The radiated field cancels out any waves scattering off the cloaked object.
Lithium-air batteries have become a hot research area in recent years: They hold the promise of drastically increasing power per battery weight, which could lead, for example, to electric cars with a much greater driving range. But bringing that promise to reality has faced a number of challenges.
Despite their almost incomprehensibly small size, single-walled carbon nanotubes come in a plethora of different “species,” each with its own structure and unique combination of electronic and optical properties. Characterizing the structure and properties of an individual carbon nanotube has involved a lot of guesswork, until now.
A new discovery by researchers from the Univ. of Notre Dame could change prevailing assumptions about the chemical makeup of the Earth’s mantle. The Univ. of Notre Dame team worked in cooperation with Vadim Kamenetsky of the Univ. of Tasmania, Hobart (Australia) to learn the art of conducting chemical and mineralogical analyses of melt inclusions within crystals of the mineral magnetite (Fe3O4).
Scientists have discovered a molecular invisibility cloak that enables HIV, the virus that causes AIDS, to hide inside cells of the body without triggering the body's natural defence systems. The findings could lead to new treatments and help to improve existing therapies for HIV infection.
Carnegie Mellon University computer scientists have developed a new password system that incorporates inkblots to provide an extra measure of protection when, as so often occurs, lists of passwords get stolen from websites. This new type of password, dubbed a GOTCHA, would be suitable for protecting high-value accounts, such as bank accounts, medical records and other sensitive information.
Using inexpensive materials configured and tuned to capture microwave signals, researchers at Duke University's Pratt School of Engineering have designed a power-harvesting device with efficiency similar to that of modern solar panels. The device wirelessly converts the microwave signal to direct current voltage capable of recharging a cell phone battery or other small electronic device.
A Russian rocket soared into the cosmos Thursday carrying the Sochi Olympic torch and three astronauts to the International Space Station ahead of the first-ever spacewalk for the symbol of peace. The unlit torch for the 2014 Winter Olympics in the Russian city of Sochi is to be taken on a spacewalk Saturday, then return to Earth on Monday (late Sunday EST) with three departing space station astronauts.
Researchers at the University of Iowa have created a bio patch to regenerate missing or damaged bone by putting DNA into a nano-sized particle that delivers bone-producing instructions directly into cells. The bone-regeneration kit relies on a collagen platform seeded with particles containing the genes needed for producing bone.
A remedy for the problem of rust may be available soon. Scientists from the Max-Planck-Institut für Eisenforschung GmbH in Düsseldorf and the Max Planck Institute for Polymer Research in Mainz have succeeded in making two strides toward developing a self-healing anticorrosion coating.
An interdisciplinary team of University of Pennsylvania researchers has already developed a technique for controlling liquid crystals by means of physical templates and elastic energy, rather than the electromagnetic fields that manipulate them in televisions and computer monitors. They envision using this technique to direct the assembly of other materials, such as nanoparticles.
How much in energy and cost savings would your state realize if it updated its commercial building energy codes? You can find out in a new online publication from the National Institute of Standards and Technology (NIST). The state-by-state reports were the product of a new building energy efficiency analysis tool developed by NIST.
Leslie Rosenberg and his colleagues are about to go hunting. Their quarry: A theorized-but-never-seen elementary particle called an axion. The search will be conducted with a recently retooled, extremely sensitive detector that is currently in a testing and shakeout phase at the University of Washington’s Center for Experimental Nuclear Physics and Astrophysics.
Scientists have puzzled for centuries over how and why multicellular organisms evolved the almost universal trait of using single cells, such as eggs and sperm, to reproduce. Now, researchers have set a big piece of that puzzle into place by applying experimental evolution to transform a single-celled algae into a multicellular one that reproduces by dispersing single cells.
Researchers from the National Institute of Standards and Technology (NIST) have joined with an international team to engineer and measure a potentially important new class of nanostructured materials for microwave and advanced communication devices.
An international team of scientists have discovered a new type of quantum material whose lopsided behavior may lend itself to creating novel electronics. The material is called bismuth tellurochloride, or BiTeCl. It belongs to a class of materials called topological insulators that conduct electrical current with perfect efficiency on their surfaces, but not through their middles.
Semiconductors have had a nice run, but for certain applications, such as astrophysics, they are being edged out by superconductors. Ben Mazin, asst. prof. of physics at the Univ. of California, Santa Barbara, has developed a superconducting detector array that measures the energy of individual photons.
Many efforts to smooth out the variability of renewable energy sources have focused on batteries, which could fill gaps lasting hours or days. But Massachusetts Institute of Technology’s Charles Forsberg has come up with a much more ambitious idea: He proposes marrying a nuclear power plant with another energy system, which he argues could add up to much more than the sum of its parts.
Scientists looking to create a potent blend of enzymes to transform materials like corn stalks and wood chips into fuels have developed a test that should turbocharge their efforts. The new research is part of a worldwide effort to create fuels from plants that are plentiful and aren't part of the food supply. It's possible to do this today, but the process is costly, laborious and lengthy.
