In the quest to understand how the brain turns sensory input into behavior, Harvard University scientists have crossed a major threshold. Using precisely targeted lasers, researchers have been able to take over a tiny animal's brain, instruct it to turn in any direction they wish, and even implant false sensor information, fooling the animal into thinking food was nearby.
Watch out, acne. Doctors soon may have a new weapon against zits: A harmless virus living on our skin that naturally seeks out and kills the bacteria that cause pimples. In the new findings, scientists looked at two little microbes that share a big name: Propionibacterium acnes , a bacterium thriving in our pores that can trigger acne, and P. acnes phages, a family of viruses that live on human skin.
A Purdue University physicist, Leonid Rokhinson, has observed evidence of long-sought Majorana fermions, special particles that could unleash the potential of fault-tolerant quantum computing. Rokhinson led a team that is the first to successfully demonstrate the fractional a.c. Josephson effect, which is a signature of the particles.
Using a novel method of integrating video technology and familiar control devices, a research team from Georgia Institute of Technology is developing a technique to simplify remote control of robotic devices. The researchers' aim is to enhance a human operator's ability to perform precise tasks using a multijointed robotic device such as an articulated mechanical arm.
The human body is proficient at making collagen. And human laboratories are getting better at it all the time. In a development that could lead to better drug design and new treatments for disease, Rice University researchers have made a major step toward synthesizing custom collagen. The scientists who have learned how to make collagen are now digging into its molecular structure to see how it forms and interacts with biological systems.
A University of Arkansas physicist and his colleagues have examined the lower limits of novel materials called complex oxides and discovered that unlike conventional semiconductors the materials not only conduct electricity, but also develop unusual magnetic properties.
Researchers from North Carolina State University have developed a new technique to identify the proteins secreted by a cell. The new approach should help researchers collect precise data on cell biology.
When it comes to germ-busting power, the eyes have it, according to a discovery by University of California, Berkeley researchers that could lead to new, inexpensive antimicrobal drugs. A team of vision scientists has found that small fragments of keratin protein in the eye play a key role in warding off pathogens.
If you throw a ball underwater, you'll find that the smaller it is, the faster it moves: A larger cross-section greatly increases the water's resistance. Now, a team of researchers has figured out a way to use this basic principle, on a microscopic scale, to carry out biomedical tests that could eventually lead to fast, compact, and versatile medical testing devices.
A Florida State University chemist's work could lead to big improvements in our ability to detect and eliminate specific toxic substances in our environment. The work involves stripping electrons from the toxic chemical known as fluoride to produce a variety of results.
Microorganisms that crashed to Earth embedded in the fragments of distant planets might have been the sprouts of life on this one, according to new research. The research team reports that under certain conditions there is a high probability that life came to Earth during the solar system's infancy when Earth and its planetary neighbors orbiting other stars would have been close enough to each other to exchange lots of solid materials.
Researchers from North Carolina State University and the Georgia Institute of Technology have demonstrated a less-expensive way to create textured nickel ferrite (NFO) ceramic thin films, which can easily be scaled up to address manufacturing needs. NFO is a magnetic material that holds promise for microwave technologies and next-generation memory devices.
Scientists at The Scripps Research Institute have shown how to synthesize in the laboratory an important set of natural compounds known as terpenes. The largest class of chemicals made by living organisms, terpenes are made within cells by some of the most complex chemical reactions found in biology.
Former and current University of Southern California Dornsife physicists have led a study that represents the first, quantitative account of the universal features of disordered bosons, or quantum particles, in magnetic materials. The study broadens our understanding of quantum mechanics and challenges accepted predication in quantum theory.
Scientists have generated holograms from carbon nanotubes, for the first time, which could lead to much sharper holograms with a vastly increased field of view. The scientists have harnessed the extraordinary conductive and light scattering abilities of these tubes to diffract high-resolution holograms.
In their quest for a cancer cure, researchers at the Duke Cancer Institute made a serendipitous discovery: a molecule necessary for cheaper and greener way to produce nylon. The finding arose from an intriguing notion that some of the genetic and chemical changes in cancer tumors might be harnessed for beneficial uses.
Glass is strong enough for so much. But scientists who look at the structure of glass strictly by the numbers believe some of the latest methods from the microelectronics and nanotechnology industry could produce glass that's about twice as strong as the best available today. Rice University researchers have determined that a process called chemical vapor deposition, which is used industrially to make thin films, is one such process.
Fabricating precise biomolecular structures at extremely small scales is critical to the progress of nanotechnology. Traditionally this has been accomplished through the use of rubber stamps with tiny features which are covered with molecular inks and then stamped onto substrate surfaces, creating molecular patterns. However, when using this technique at the nanoscale, molecules tend to diffuse on the surface both during and after stamping, blurring the patterns. Now, a team of researchers have turned this "soft lithography" process on its head.
A team of researchers have used surface photochemical reactions to probe the critical role of substrate morphology on self-assembly and ligand environment, determining that molecules on curved surfaces have a greater range of orientations and, as a result, react more slowly than do molecules on flat surfaces.
University of Oregon scientists have found a way to correctly reproduce not only the structure but also important thermodynamic quantities, such as pressure and compressibility, of a large, multiscale system at variable levels of molecular coarse-graining.
A Flinders University researchers has been developing a cheaper and faster way of making large-scale plastic solar cells using a lamination technique, paving the way for a lucrative new clean energy industry. The method is a promising alternative to the expensive fabrication techniques currently used in the renewable energy sector, and would make the commercialization of plastic solar cell technology more viable.
Northwestern University scientists have developed a thermoelectric material that is, according to the university, the best in the world at converting waste heat to electricity, which is good news once one realizes nearly two-thirds of energy input is lost as waste heat. The material could signify a paradigm shift.
A new study of the sense of small lends support to a controversial theory of olfaction: Our noses can distinguish both the shape and vibrational characteristics of odorant molecules. The study demonstrates the feasibility of the theory that the vibration of an odorant molecule's chemical bonds contributes to our ability to distinguish one smelly thing from another.
The next step in building graphene-based electronic devices requires creating junctions that connect graphene to the external world through at least two metal wires. A two-terminal junction is a graphene ribbon with two metal contacts. A team of researchers have developed a better understanding of how these graphene-metal interfaces affect the movement of electrons through two-terminal junctions.
A new pediatric medical devices being developed by Georgia Institute of Technology and Emory University could make life easier for parents who have rushed to the doctor with a child screaming from an ear infection. Soon, parents may be able to skip the doctor's visit and receive a diagnosis without leaving home by using Remotoscope, a clip-on attachment and software app that turns an iPhone into an otoscope.
