Dartmouth College astrophysicists and their colleagues haven’t only proven that a supermassive black hole exists in a place where it isn't supposed to be, but in doing so have opened a new door to what things were like in the early universe. Henize 2-10 is a small irregular galaxy that is not too far away in astronomical terms: 30 million light-years.
With a tag, an anchor and a cage that can be unlocked with light, chemists have devised a simple, modular system that can locate proteins at the membrane of a cell. The chemists fused proteins to molecules called SNAP-tags, modified enzymes that recognize a particular chemical group called a benzylguanine.
In a move that could improve the energy storage of everything from portable electronics to electric microgrids, Univ. of Wisconsin-Madison and Brookhaven National Laboratory researchers have developed a novel x-ray imaging technique to visualize and study the electrochemical reactions in lithium-ion rechargeable batteries containing a new type of material, iron fluoride.
A more effective method for closing gaps in atomically small wires has been developed by Univ. of Illinois researchers, further opening the doors to a new transistor technology. Silicon-based transistors have been the foundation of modern electronics for more than half a century. A new transistor technology, carbon nanotube wires, shows promise in replacing silicon because it can operate ten times as fast and is more flexible.
Massachusetts Institute of Technology physicists have developed a new tabletop particle detector that is able to identify single electrons in a radioactive gas. As the gas decays and gives off electrons, the detector uses a magnet to trap them in a magnetic bottle. A radio antenna then picks up very weak signals emitted by the electrons, which can be used to map the electrons’ precise activity over several milliseconds.
Proximity effects in hybrid heterostructures, which contain distinct layers of different materials, allow one material species to reveal and/or control properties of a dissimilar species. Specifically, for a magnetic thin film deposited onto a transition metal oxide film, the magnetic properties change dramatically as the oxide undergoes a structural phase transition.
Sudden cardiac death accounts for approximately 10 percent of natural deaths, most of which are due to ventricular fibrillation. Each year it causes 300,000 deaths in the United States and 20,000 in Spain. Researchers have demonstrated for the first time that the transition to calcium alternans, an arrhythmia associated with increased risk of sudden death, has common features with the magnetic ordering of metals.
The editors of R&D Magazine have announced a deadline extension for the 2015 R&D 100 Awards entry process until May 18, 2015. The R&D 100 Awards have a 50 plus year history of awarding the 100 most technologically significant products of the year.
A new paper describes how an accurate statistical description of heterogeneous particulate materials, which is used within statistical micromechanics theories, governs the overall thermo-mechanical properties. This detailed statistical description was computed using a novel adaptive interpolation/integration scheme on the nation’s largest parallel supercomputers.
Tim Studt here again, and mostly recovered from my day-long travel on Friday. Hot and humid here in Taipei, about 25 F warmer than in Chicago. Today's judging at the Taiwan Excellence Awards covered healthcare-based tablet computers, electronic memory modules, top-end gaming computers, electric scooters, racing bicycles and even off-road mountain racing bike tires.
This month's issue of R&D Magazine features a cover story on biofuels. Recent growth in petroleum supplies and a slide in prices has cut into biofuel research funding. Our editors also provide features on lab utilities, vibration control design, image analysis, digital multimeters, spectroscopy and more.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf and the Univ. of Konstanz are working on storing and processing information on the level of single molecules to create the smallest possible components that will combine autonomously to form a circuit. As recently reported in Advanced Science, the researchers can switch on the current flow through a single molecule for the first time with the help of light.
Water is one of the most common and extensively studied substances on earth. It’s vital for all known forms of life but its unique behavior has yet to be explained in terms of the properties of individual molecules. Water derives many of its signature features from a combination of properties at the molecular level such as high polarizability, directional hydrogen bonding sites and van der Waals forces.
As two galaxies enter the final stages of merging, scientists have theorized that the galaxies' supermassive black holes will form a "binary," or two black holes in such close orbit they are gravitationally bound to one another. In a new study, astronomers at the Univ. of Maryland present direct evidence of a pulsing quasar, which may substantiate the existence of black hole binaries.
Tim Studt here in Taipei judging the 23rd annual Taiwan Excellence Awards with seven other judges from Germany, Japan and Taiwan academia. Sponsored by the Taiwan Ministry of Economic Affairs, these awards were developed to encourage Taiwan companies to incorporate innovation and value into their products. Selection of winners are based on R&D, design, quality and marketing/branding.
Partnerships between universities and businesses are nothing new, but these partnerships have become especially relevant in the face of increasing economic pressure and global competition, the need for interdisciplinary approaches and the growing complexity of the problems need solutions. In recent years, there has been a resurgence of partnering between academic institutions and private industry.
In 2004, astronomers examining a map of the radiation leftover from the Big Bang (the cosmic microwave background, or CMB) discovered the Cold Spot, a larger-than-expected unusually cold area of the sky. The physics surrounding the Big Bang theory predicts warmer and cooler spots of various sizes in the infant universe, but a spot this large and this cold was unexpected.
It can shift from red to green to violet. It can mimic patterns and designs. And it can do all of this in a flash, literally. The same qualities that define the cuttlefish, a sea dweller that uses its powers of dynamic camouflage to survive and communicate, also apply to a new engineering feat that behaves much like nature's master of disguise.
An experiment led by the Univ. of Colorado Boulder arrived at the International Space Station (ISS) and will look into the fluid dynamics of liquid crystals that may lead to benefits both on Earth and in space. A new physical science investigation on ISS, the Observation and Analysis of Smectic Islands in Space (OASIS), will examine the behavior of liquid crystals in microgravity.
Human emotion can be transferred by technology that stimulates different parts of the hand without making physical contact with your body, a Univ. of Sussex-led study has shown. Sussex scientist Dr. Marianna Obrist has pinpointed how next-generation technologies can stimulate different areas of the hand to convey feelings of, for example, happiness, sadness, excitement or fear.
Astronomers have probed deeper than before into a planetary system 130 light-years from Earth. The observations mark the first results of a new exoplanet survey called LEECH (LBT Exozodi Exoplanet Common Hunt). The planetary system of HR8799, a young star only 30 million years old, was the first to be directly imaged, with three planets found in in 2008 and a fourth one in 2010.
A nonprofit company planning to build one of the world's biggest telescopes on a mountain many Native Hawaiians consider sacred will continue to postpone construction, Hawaii Gov. David Ige said Friday. This is the second time the Thirty Meter Telescope has extended a moratorium on building at the summit of Mauna Kea, the highest peak on the Big Island of Hawaii.
Immediately following the passage of the Energy Independence and Security Act (EISA) of 2007, much research interest focused on the development of bio-based renewable energy sources (biofuels). EISA mandated increased production and use of biofuels for the long term. There also appeared to be substantial long-term government support for the implementation of a biofuel-based industry.
The design of laboratories for sustainable construction and operation has become a major driver in the A/E/C industry over the past 10 to 15 years. These days, most lab clients are looking for sustainable design approaches at a minimum—and third-party certification, such as LEED, in many cases.
In the past decade, the expansion of research focus areas in engineering has undergone a transformation. The demands of engineering labs present challenges for institutions because most occupied spaces were conceived during an era with radically different needs and required services.
