Scientists, for the first time, have precisely measured a protein’s natural “knee-jerk” reaction...
When it comes to magnets, a doctor’s trash is a physicist’s treasure. Researchers at Argonne National Laboratory recently acquired two decommissioned magnets from magnetic resonance imaging (MRI) scanners from hospitals in Minnesota and California that will find a new home as proving grounds for instruments used in high-energy and nuclear physics experiments.
Purdue Univ. research shows that a small amount of nicotinoid pesticide substantially weakens termites' ability to fight off fungal diseases, a finding that could lead to more effective methods of pest control. The study also provides clues into termites' robust defense systems and how nicotinoids affect social insects.
Massachusetts Institute of Technology researchers have shown that they can use a microfluidic cell-squeezing device to introduce specific antigens inside the immune system’s B cells, providing a new approach to developing and implementing antigen-presenting cell vaccines.
An automated software system developed at Los Alamos National Laboratory played a key role in the discovery of supernova iPTF 14atg and could provide insight, a virtual Rosetta stone, into future supernovae and their underlying physics.
Chemists at The Scripps Research Institute have discovered a broad and strikingly inexpensive method for synthesizing “amines,” a class of organic compounds prominent in drugs and other modern products. The new reaction is particularly useful for synthesizing complex amines that would be highly valuable in pharmaceuticals, but are impractical—or impossible—to make with standard methods.
Astronomers using NASA's Hubble Space Telescope have uncovered surprising new clues about a hefty, rapidly aging star whose behavior has never been seen before in our Milky Way galaxy. In fact, the star is so weird that astronomers have nicknamed it "Nasty 1," a play on its catalog name of NaSt1. The star may represent a brief transitory stage in the evolution of extremely massive stars.
An existing anti-stroke drug is an effective treatment for middle-ear infections, showing the ability to suppress mucus overproduction, improve bacterial clearance and reduce hearing loss, according to researchers at Georgia State Univ. and the Univ. of Rochester. The findings could result in a novel, non-antibiotic treatment for otitis media, or middle-ear infection, possibly through topical drug delivery.
Where do electronics go when they die? Most devices are laid to eternal rest in landfills. But what if they just dissolved away, or broke down to their molecular components so that the material could be recycled? Univ. of Illinois researchers have developed heat-triggered self-destructing electronic devices, a step toward greatly reducing electronic waste and boosting sustainability in device manufacturing.
Lawrence Livermore National Laboratory (lLNL) researchers have determined that a tunnel bomb explosion by Syrian rebels was less than 60 tons as claimed by sources. Using seismic stations in Turkey, LLNL scientists created a method to determine source characteristics of near-earth surface explosions.
Scientists operating the world's biggest particle collider say they have set a new energy record ahead of the massive machine's full restart in June. The European Organization for Nuclear Research, or CERN, says it succeeded late Wednesday in smashing together protons at 13 trillion electronvolts.
A fluffy galaxy is hard to find, but that didn’t stop a Yale Univ. astronomer and an international research team from identifying the fluffiest galaxies in the universe. These “ultra-diffuse” galaxies are located about 300 million light years from Earth, in the Coma cluster of galaxies. What makes them fluffy? It is this: Although they are as wide as our own Milky Way galaxy, they harbor only 1% as many stars.
Most people see defects as flaws. A few Michigan Technological Univ. researchers, however, see them as opportunities. Twin boundaries may present an opportunity to improve lithium-ion batteries. The twin boundary defects act as energy highways and could help get better performance out of the batteries. This finding turns a previously held notion of material defects on its head.
Despite efforts over decades to diversify the ranks of university faculty, only 4% of chemistry professorships at 50 leading U.S. colleges and universities are held by underrepresented minorities. That key finding and others related to diversity in academia came from a new survey conducted by a program called Open Chemistry Collaborative in Diversity Equity (OXIDE) in partnership with Chemical & Engineering News.
Last summer, MIT researchers published a paper describing an algorithm that can recover intelligible speech from the analysis of the minute vibrations of objects in video captured through soundproof glass. In June, researchers from the same groups will describe how the technique can be adapted to infer material properties of physical objects, such as stiffness and weight, from video.
A new class of magnets that expand their volume when placed in a magnetic field and generate negligible amounts of wasteful heat during energy harvesting, has been discovered by researchers at Temple Univ. and the Univ. of Maryland. This transformative breakthrough has the potential to not only displace existing technologies but create altogether new applications due to the unusual combination of magnetic properties.
Radio systems, such as mobile phones and wireless Internet connections, have become an integral part of modern life. However, today's devices use twice as much of the radio spectrum as is necessary. New technology is being developed that could fundamentally change radio design and could increase data rates and network capacity, reduce power consumption, create cheaper devices and enable global roaming.
Computer simulations have predicted a new phase of matter: atomically thin 2-D liquid. This prediction pushes the boundaries of possible phases of materials further than ever before. Two-dimensional materials themselves were considered impossible until the discovery of graphene around 10 years ago.
For decades, the fundamental design of microwave devices, such as antennas for mobile communication and waveguides used in radars, has essentially relied on the inventiveness of a professional designer. Computer simulations are usually used only in final design stages to fine-tune details in the design.
The number of new Ebola cases is tapering off, but the search for new treatments continues. Now, one research team has found potential drug candidates that successfully treated up to 90% of mice exposed to the Ebola virus. They report their findings in ACS Infectious Diseases.
Not all plastics are created equal. Malleable thermoplastics can be easily melted and reused in products such as food containers. Other plastics, called thermosets, are essentially stuck in their final form because of cross-linking chemical bonds that give them their strength for applications such as golf balls and car tires.
In the story of the Marvel Universe superhero known as the Hulk, exposure to gamma radiation transforms scientist Bruce Banner into a far more powerful version of himself. In a study at Lawrence Berkeley National Laboratory, exposure to alpha-particle radiation has been shown to transform certain thermoelectric materials into far more powerful versions of themselves.
Americans' energy use continued to grow slowly in 2014, fueled by increases in the use of natural gas, wind and solar, according to the most recent energy flow charts released by Lawrence Livermore National Laboratory (LLNL). Each year, the LLNL releases charts that illustrate the nation's consumption and use of energy. Overall, Americans used 0.9 quads BTUs more in 2014 than the previous year, an increase of about 1%.
Type Ia supernovae, one of the most dazzling phenomena in the universe, are produced when small dense stars called white dwarfs explode with ferocious intensity. At their peak, these supernovae can outshine an entire galaxy. Although thousands of supernovae of this kind were found in the last decades, the process by which a white dwarf becomes one has been unclear.
The latest version of a microfluidic device for capturing rare circulating tumor cells is the first designed specifically to capture clusters of two or more cells, rather than single cells. The new device, called the Cluster-Chip, was developed by the same Massachusetts General Hospital (MGH) research team that created previous microchip-based devices.
Graphene is a material with a host of potential applications, including in flexible light sources, solar panels that could be integrated into windows and membranes to desalinate and purify water. But all these possible uses face the same big hurdle: the need for a scalable and cost-effective method for continuous manufacturing of graphene films.
