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.
Nitric oxide (NO) is one of the most important signaling molecules in living cells, carrying messages within the brain and coordinating immune system functions. In many cancerous cells, levels are perturbed, but very little is known about how NO behaves in both healthy and cancerous cells. Until now.
Amit Goyal and his team of research scientists are using copper oxide to redesign the face of solar power. The once-dismissed solar semiconductor, one of the first discovered, is the basis of ongoing research at Oak Ridge National Laboratory, where scientists are creating cheaper and safer alternatives for solar conducting technology.
In August, Massachusetts Institute of Technology researchers identified an exoplanet with an extremely brief orbital period: The team found that Kepler 78b, a small, intensely hot planet 400 light-years from Earth, circles its star in just 8.5 hrs. Now this same team has found that Kepler 78b shares another characteristic with Earth: its mass.
Doctors may one day be able to control a patient's HIV infection in a new way: injecting swarms of germ-fighting antibodies, two new studies suggest. In monkeys, that strategy sharply reduced blood levels of a cousin of HIV. The results also gave tantalizing hints that someday the tactic might help destroy the AIDS virus in its hiding places in the body, something current drugs cannot do.
Taking inspiration from the human immune system, researchers at Lawrence Berkeley National Laboratory have created a new material that can be programmed to identify an endless variety of molecules. The new material resembles tiny sheets of Velcro, each just one-hundred nanometers across. But instead of securing your sneakers, this molecular Velcro mimics the way natural antibodies recognize viruses and toxins.
A brain stimulation technique that is used to treat tough cases of depression could be considerably improved with a new headpiece designed by Univ. of Michigan engineers. Computer simulations showed that the headpiece—a square array of 64 circular metallic coils—could one day help researchers and doctors hit finer targets in the brain that are twice as deep as they can reach today, and without causing pain.
Advances in computer storage have created collections of data so huge that researchers often have trouble uncovering critical patterns in connections among individual items, making it difficult for them to realize fully the power of computing as a research tool. Now, computer scientists at Princeton Univ. have developed a method that offers a solution to this data overload.
A lens with ten times the resolution of any current lens, making it a powerful new tool for the biological sciences, has been developed by researchers at the Univ. of Sydney. The lens was created using fiber-optic manufacturing technology, and is a metamaterial, or a material with completely new properties not found in nature.
In a pair of studies that exploit the genetic sequencing of the “missing link” cold virus, rhinovirus C, scientists at the Univ. of Wisconsin-Madison have constructed a 3-D model of the pathogen that shows why there is no cure yet for the common cold. The new cold virus model was built in silico, drawing on advanced bioinformatics and the genetic sequences of 500 rhinovirus C genomes, which provided 3-D coordinates of the viral capsid.
The ability to shrink laboratory-scale processes to automated chip-sized systems would revolutionize biotechnology and medicine. One of the challenges of lab-on-a-chip technology is the need for miniaturized pumps to move solutions through microchannels. A super-thin silicon membrane developed at the Univ. of Rochester could now make it possible to shrink the power source, paving the way for diagnostic devices the size of a credit card.
Accurate and rapid testing for drug toxicity just became easier, thanks to a half-dozen Rice Univ. student interns working at Houston-based startup Nano3D Biosciences (n3D). The bioengineering and nanoscale physics students just wrapped up a year-long effort to aid the company in developing a new method for conducting high-throughput, in vitro cytotoxicity assays.
The editors of R&D Magazine and Laboratory Design are now accepting entries to the 48th international Laboratory of the Year competition.

The entry deadline is January 31, 2014 (11:59p.m. Eastern Standard Time).
Nanomaterials are the heart of the smaller, better electronics developed during the last decade, as well as new materials, medical diagnostics, energy storage and clean water. However, exposure to nanomaterials may have unintended consequences for human health and the environment. As a resource, Virginia Tech has joined the Woodrow Wilson International Center for Scholars to renew and expand the Nanotechnology Consumer Product Inventory.
Structures that put a spin on light reveal tiny amounts of DNA with 50 times better sensitivity than the best current methods, a collaboration between the Univ. of Michigan and Jiangnan Univ. in China has shown. Highly sensitive detection of DNA can help with diagnosing patients, solving crimes and identifying the origins of biological contaminants such as a pathogen in a water supply.
Dark matter, believed by physicists to outweigh all the normal matter in the universe by more than five to one, is by definition invisible. But certain features associated with dark matter might be detectable, according to some of the many competing theories describing this elusive matter. Now scientists have developed a tool that could test some of these predictions and thus prove, or disprove, one of the leading theories.
