Engineers improve performance of high-temperature superconductor wires

Florida State University researchers have discovered a novel way to improve the performance of electrical wires used as high-temperature superconductors (HTS), findings that have the potential to power a new generation of particle accelerators.

Photonic MEMS switches going commercial

One of the technical challenges the current data revolution faces is finding an efficient way to route the data. This task is usually performed by electronic switches, while the data itself is transferred using light confined in optical waveguides. For this reason, conversion from an optical to an electronic signal and back-conversion are required, which costs energy and limits the amount of transferable information. These drawbacks are avoidable with a full optical switch operation. One of the most promising approaches is based on microelectromechanical systems (MEMS), thanks to decisive advantages such as low optical loss and energy consumption, monolithic integration, and high scalability. Indeed, the largest photonic switch ever demonstrated uses this approach.

Tracking the progress of fusion power through 60 years of neutral particle analysis

As the world's energy demands grow, so too does growing concern over the environmental impact of power production. The need for a safe, clean, and reliable energy source has never been clearer. Fusion power could fulfil such a need. A review paper published in The European Physical Journal H examines the 6-decade history of neutral particle analysis (NPA), developed in Ioffe Institute, Saint Petersburg, Russia, a vital diagnostic tool used in magnetic plasma confinement devices such as tokamaks that will house the nuclear fusion process and generate the clean energy of the future.

In a study published in Nature Astronomy, they examined the bursts in the greatest possible detail. While the articles provide new information, they also raise new questions.

Researchers identify five double star systems potentially suitable for life

Almost half a century ago the creators of Star Wars imagined a life-sustaining planet, Tatooine, orbiting a pair of stars. Now, 44 years later, scientists have found new evidence that that five known systems with multiple stars, Kepler-34, -35, -38, -64 and -413, are possible candidates for supporting life. A newly developed mathematical framework allowed researchers at New York University Abu Dhabi and the University of Washington to show that those systems—between 2764 and 5933 light years from Earth, in the constellations Lyra and Cygnus—support a permanent "Habitable Zone", a region around stars in which liquid water could persist on the surface of any as yet undiscovered Earth-like planets. Of these systems, Kepler-64 is known to have at least four stars orbiting one another at its center, while the others have two stars. All are known to have at least one giant planet the size of Neptune or greater. This study, published in Frontiers in Astronomy and Space Sciences, is proof-of-principle that the presence of giant planets in binary systems does not preclude the existence of potentially life-supporting worlds.

Peering through the clouds of Earth's 'Evil Twin' surprises NRL sky watchers

U.S. Naval Research Laboratory scientists were recently left scratching their heads over a familiar sight in the sky. Venus images are nothing new, but a solar probe surprised the researchers by seeing through the planet's clouds. NRL's Wide-field Imager for Parker Solar Probe (WISPR) took a stunning image of Earth's celestial neighbor Venus last year that left researchers searching for answers as to how what they were seeing was possible. Expecting to see just the featureless Venusian clouds, the NRL WISPR team were instead shocked at what they saw.

New NASA visualization probes the light-bending dance of binary black holes

Transparent nanolayers pave the way for production of silicon solar cells with more than 26% efficiency

There is no cheaper way to generate electricity today than with the sun. Power plants are currently under construction in sunny locations that will supply solar electricity for less than 2 cents per kilowatt hour. Solar cells available on the market based on crystalline silicon make this possible with efficiencies of up to 23 percent. Therefore they hold a global market share of around 95 percent. With even higher efficiencies of more than 26 percent, costs could fall further. An international working group led by photovoltaics researchers from Forschungszentrum J├╝lich now plan to reach this goal with a nanostructured, transparent material for the front of solar cells and a sophisticated design. The scientists report on their success of many years of research in the renowned scientific journal Nature Energy.

Study identifies a universal property for efficient communication

Words categorize the semantic fields they refer to in ways that maximize communication accuracy while minimizing complexity. Recent studies have shown that human languages are optimally balanced between accuracy and complexity. For example, many languages have a word that denotes the color red, but no language has individual words to distinguish ten different shades of the color. These additional words would complicate the vocabulary and rarely would they be useful to achieve precise communication.
