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.
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.
