In its 49th year, the Laboratory of the Year Awards continue to recognize excellence in research laboratory design, planning and construction. Judging for this year’s competition took place on Thursday, February 19th and was conducted by a blue-ribbon panel of laboratory architects, engineers, equipment manufacturers, researchers and the editors of R&D Magazine and Laboratory Design Newsletter.
As urban residents know, air quality is a big deal. When local pollution levels go up, the associated health risks also increase, especially for children and seniors. But air pollution varies widely over the course of a day and by location, even within the same city. Now scientists, reporting in Environmental Science & Technology, have used smartphone and sensing technology to better pinpoint where and when pollution is at its worst.
Graphene shows great promise for future electronics, advanced solar cells, protective coatings and other uses, and combining it with other materials could extend its range even further. Experiments at the SLAC National Accelerator Laboratory looked at the properties of materials that combine graphene with a common type of semiconducting polymer.
Scientists have known how to draw thin fibers from bulk materials for decades. But a new approach to that old method, developed by researchers at Massachusetts Institute of Technology, could lead to a whole new way of making high-quality fiber-based electronic devices. The idea grew out of a long-term research effort to develop multifunctional fibers that incorporate different materials into a single long functional strand.
Smartphones and tablets are everywhere, which is great for communications but a growing burden on wireless channels. Forecasted huge increases in mobile data traffic call for exponentially more channel capacity. Boosting bandwidth and capacity could speed downloads, improve service quality and enable new applications like the Internet of Things connecting a multitude of devices.
Graphene is often touted as a replacement for silicon in electronic devices due to its extremely high conductivity and unbeatable thinness. But graphene isn’t the only 2-D material that could play such a role. Univ. of Pennsylvania researchers have made an advance in manufacturing one such material, molybdenum disulphide.
Most lenses are, by definition, curved. After all, they are named for their resemblance to lentils, and a glass lens made flat is just a window with no special powers. But a new type of lens created at the Harvard School of Engineering and Applied Sciences turns conventional optics on its head.
By looking at the speed of ambient gas spewing out from a well-known quasar, astronomers are gaining insight into how black holes and their host galaxies might have evolved at the same time. Using the Nuclear Spectroscopic Telescope Array (NuSTAR), researchers were able to use the x-ray spectra of an extremely luminous black hole (quasar PDS 456) to detect a nearly spherical stream of highly ionized gas streaming out of it.
Earth's past, present and future come together here on the northern peninsula of Antarctica, the wildest, most desolate and mysterious of its continents. Clues to answering humanity's most basic questions are locked in this continental freezer the size of the U.S. and half of Canada: Where did we come from? Are we alone in the universe? What's the fate of our warming planet?
Federal health officials are easing access to DNA tests used to screen parents for devastating genetic disorders that can be passed on to their children. The surprise announcement offers a path forward for Google-backed genetic testing firm 23andMe, which previously clashed with regulators over its direct-to-consumer technology.
Scientists have created a high-energy mid-infrared laser powerful enough to create shining filaments in the air. Such devices could be used to detect chemical substances in the atmosphere.
Researchers have revealed previously unobserved behaviors that show how details of the transfer of heat at the nanoscale cause nanoparticles to change shape in ensembles.
New research has shown that a 2013 solar storm produced “ultrarelativistic, killer electrons” in 60 seconds, disrupting Earth's magnetic field and setting off a magnetized sound pulse around the planet.
Single-letter genetic variations within parts of the genome once dismissed as 'junk DNA' can increase cancer risk through wormhole-like effects on far-off genes, new research shows.
Research concludes that Earth's infrequent but predictable path around and through our Galaxy's disc may have a direct and significant effect on geological and biological phenomena occurring on Earth.
Researchers have successfully created electricity-generating solar-cells with chemicals found the shells of shrimps and other crustaceans for the first time.
Terpenes and their derivatives exert important biological and pharmaceutical functions. Starting out from a few basic building blocks nature elegantly builds up complex structures. Chemically particularly challenging are bridged ring systems such as eucalyptol. Chemists at the Technical Univ. Munich have developed a catalyst that initiates the formation of such compounds.
Redesigned Environmental Protection Agency fuel economy labels on cars for sale are likely ineffective in pointing out total savings of hybrid and electric plug-in cars over gasoline vehicles, according to new research involving two Univ. of Kansas professors. The researchers found that consumers for small to mid-sized cars would be more likely to choose a hybrid or plug-in electric vehicle if they know the total cost of ownership.
Researchers succeeded in creating an electrocatalyst that is needed for storing electric energy made of carbon and iron. A challenge that comes with the increased use of renewable energy is how to store electric energy. Platinum has traditionally been used as the electrocatalyst in electrolyzers that store electric energy as chemical compounds.
Our susceptibility to disease depends both on the genes that we inherit from our parents and on our lifetime experiences. These two components—nature and nurture—seem to affect very different processes in the context of Alzheimer's disease, according to a new study published in Nature.
Electrical impulses play an important role in cells of the human body. For example, neurons use these impulses to transmit information along their branches and the body also uses them to control the contraction of muscles. The impulses are generated when special channel proteins open in the outer envelope of the cells, allowing charged molecules (ions) to enter or exit the cell. These proteins are referred to as ion channels.
Researchers at the Univ. of California, Riverside have developed a novel paper-like material for lithium-ion batteries. It has the potential to boost by several times the specific energy, or amount of energy that can be delivered per unit weight of the battery. This paper-like material is composed of sponge-like silicon nanofibers more than 100 times thinner than human hair.
Researchers have long sought alternatives to morphine that curb its side effects, including dependency, nausea and dizziness. Now, an experiment at SLAC National Accelerator Laboratory has supplied the most complete atomic-scale map of such a compound docked with a cellular receptor that regulates the body’s pain response and tolerance.
While genomics is the study of all of the genes in a cell or organism, epigenomics is the study of all the genomic add-ons and changes that influence gene expression but aren’t encoded in the DNA sequence. A variety of new epigenomic information is now available in a collection of studies published in Nature by the National Institutes of Health Roadmap Epigenomics Program.
Researchers at the Univ. of Illinois at Urbana-Champaign have developed a unique single-step process to achieve 3-D texturing of graphene and graphite. Using a commercially available thermally activated shape-memory polymer substrate, this 3-D texturing, or "crumpling," allows for increased surface area and opens the doors to expanded capabilities for electronics and biomaterials.
