For 28 years, the Hubble Space Telescope has been delivering breathtaking views of the universe. The latest offering is this image of the Lagoon Nebula to celebrate the telescope's anniversary. Hubble shows the roiling heart of this vast stellar nursery in stunning unprecedented detail.
Brookhaven Lab Materials Physicist Yimei Zhu Receives 2018 Distinguished Scientist Award from the Microscopy Society of America
How do complex atomic and electronic interactions impact material properties? Using electron microscopy instrumentation and methods he developed, Yimei Zhu has been investigating this question for the past 30 years. The Microscopy Society of America is now recognizing his contributions.
Each year, the effects of corroding materials sap more than $1 trillion from the global economy. As certain alloys are exposed to extreme stress and temperatures, an oxide film begins to form, causing the alloys to break down even more quickly. What precisely makes these conditions so conducive for corrosion, however, remains poorly understood, especially in microelectromechanical devices. Chinese researchers have started to chip away at why these materials corrode under mechanical stress; they describe their work in the Journal of Applied Physics.
Machine learning algorithms excel at finding complex patterns within big data, so researchers often use them to make predictions. Researchers are pushing the technology beyond finding correlations to help uncover hidden cause-effect relationships and drive scientific discoveries. At the University of South Florida, researchers are integrating machine learning techniques into their work studying proteins. As they report in The Journal of Chemical Physics, one of their main challenges has been a lack of methods to identify cause-effect relationships in data obtained from molecular dynamics simulations.
Theoretical physicists used simulations to explain the unusual readings collected in 2009 by the Mercury Surface, Space Environment, Geochemistry, and Ranging mission. The origin of energetic electrons detected in Mercury's magnetic tail has puzzled scientists. This new study, appearing in Physics of Plasmas, provides a possible solution to how these energetic electrons form.
Earlier today, April 16, 2018, U.S. Secretary of Energy Rick Perry and India's Atomic Energy Secretary Dr. Sekhar Basu signed an agreement in New Delhi to expand the two countries' collaboration on world-leading science and technology projects. It opens the way for jointly advancing cutting-edge neutrino science projects under way in both countries: the Long-Baseline Neutrino Facility (LBNF) with the international Deep Underground Neutrino Experiment (DUNE) hosted at the U.S. Department of Energy's Fermilab and the India-based Neutrino Observatory (INO).
Planets orbiting "short-period" binary stars, or stars locked in close orbital embrace, can be ejected off into space as a consequence of their host stars' evolution, according to new research from the University of Washington.
Scientists demonstrated that powerful acids heal certain structural defects in synthetic films.
Lasting just a few hundred billionths of a billionth of a second, these bursts offer new tool to study chemistry and magnetism.
Scientists have decoded faint distortions in the patterns of the universe's earliest light to map huge tubelike structures invisible to our eyes - known as filaments - that serve as superhighways for delivering matter to dense hubs such as galaxy clusters.
When power generators transfer electricity to homes, businesses and the power grid, they lose almost 10 percent of the generated power. To address this problem, scientists are researching new diamond semiconductor circuits to make power conversion systems more efficient. Researchers in Japan successfully fabricated a key circuit in power conversion systems using hydrogenated diamond. These circuits can be used in diamond-based electronic devices that are smaller, lighter and more efficient than silicon-based devices. They report their findings in this week's Applied Physics Letters.
This week, the Axion Dark Matter Experiment (ADMX) unveiled a new result, published in Physical Review Letters, that places it in a category of one: It is the world's first and only experiment to have achieved the necessary sensitivity to "hear" the telltale signs of dark matter axions. This technological breakthrough is the result of more than 30 years of research and development, with the latest piece of the puzzle coming in the form of a quantum-enabled device that allows ADMX to listen for axions more closely than any experiment ever built.
The term "superfluid quasicrystal" sounds like something a comic-book villain might use to carry out his dastardly plans. In reality, it's a new form of matter proposed by theoretical physicists at The University of Texas at Dallas in a recent study published in the journal Physical Review Letters.
A group of scientists working on the MiniBooNE experiment at the Department of Energy's Fermilab has reported a breakthrough: They were able to identify exactly-known-energy muon neutrinos hitting the atoms at the heart of their particle detector. The result eliminates a major source of uncertainty when testing theoretical models of neutrino interactions and neutrino oscillations.
During a recent weeklong coding marathon at Brookhaven Lab, scientists, code developers, and computing hardware experts achieved from 2x to 40x speedups for scientific application codes running on supercomputers powered by Intel processors for high-performance computing.
Science promises to sound more exciting than ever at this year's Acoustical Society of America meeting. Presenters will reveal the latest in acoustics research with insight into topics like how new materials could control acoustic waves, improving audio in virtual reality, acoustic levitation, and how certain insects use acoustics to attract a mate, as well as much more.
A 21-year NSF-funded program that brings undergraduate students to UAB for a summer of materials research has been renewed with a grant from the NSF Division of Materials Research. The students come from underrepresented groups and from schools where research opportunities are limited.
Iowa State University's Steve Kawaler is heading back to Cape Canaveral this month to witness the launch of another planet-hunting spacecraft. This one, called TESS, will image 85 percent of the sky over the next two years, helping astronomers find planets beyond our solar system. Kawaler and other astronomers will also use TESS data to study stars.
