  • Simulations provide clue to missing planets mystery

    New supercomputer simulations show that after creating a ring, a planet can move away and leave the ring behind. Not only does this bolster the planet theory for ring formation, the simulations show that a migrating planet can produce a variety of patterns matching those actually observed in disks. Young stars are encircled by protoplanetary…

  • Spreading the sound

    Scientists are studying the motion of sound waves in glassy materials using a new theoretical model and find that they can diffuse like fluids, which may lead to the design of more resilient touchscreens. Understanding the possible vibrational modes in a material is important for controlling its optical, thermal, and mechanical properties. The propagation of…

  • A new ultrafast control scheme of ferromagnet for energy-efficient data storage

    Using a single laser pulse that did not switch the ferrimagnetic layer, researchers demonstrated a much faster and less energy consuming switching of the ferromagnet. Researchers at the Universite de Lorraine in France and Tohoku University reported on an innovative technology that leads to a drastic reduction in energy for data storage. The established technology…

  • Lean and mean: Building a multifunctional pressure sensor with 3D printing technology

    Pressure sensors are important tools for accurate sensing of applied forces. However, they can mostly sense forces along only a single direction. In a new study, scientists take things to the next level with a multi-directional pressure sensor fabricated using 3D-printed conductive polymer composites and paired with a temperature sensor for resistance calibration. The low…

  • Artificial intelligence enhances efficacy of sleep disorder treatments

    An algorithm based on 20,000 nights of sleep that can improve the diagnosis, treatment and our overall understanding of sleep disorders has been developed. In a new study, researchers from the University of Copenhagen’s Department of Computer Science have collaborated with the Danish Center for Sleep Medicine at the danish hospital Rigshospitalet to develop an…

  • A Martian mash up: Meteorites tell story of Mars’ water history

    Researchers probed Martian meteorites to reconstruct Mars’ chaotic history. Their findings suggest that Mars might not have had a global magma ocean. Barnes is an assistant professor of planetary sciences in the University of Arizona Lunar and Planetary Laboratory. She and her team chemically analyzed the Black Beauty meteorite and the infamous Allan Hills 84001…

  • Bringing the sun into the lab

    Why the sun’s corona reaches temperatures of several million degrees Celsius is one of the great mysteries of solar physics. A ‘hot’ trail to explain this effect leads to a region of the solar atmosphere just below the corona, where sound waves and certain plasma waves travel at the same speed. In an experiment using…

  • Breakthrough in nuclear physics

    The positively charged protons in atomic nuclei should actually repel each other, and yet even heavy nuclei with many protons and neutrons stick together. The so-called strong interaction is responsible for this. Scientists have now developed a method to precisely measure the strong interaction utilizing particle collisions in the ALICE experiment at CERN in Geneva.…

  • Volcanoes might light up the night sky of this planet

    Until now, researchers have found no evidence of global tectonic activity on planets outside our solar system. Scientists have now found that the material inside planet LHS 3844b flows from one hemisphere to the other and could be responsible for numerous volcanic eruptions on one side of the planet. Until now, researchers have found no…

  • Smartphone breath alcohol testing devices vary widely in accuracy

    The latest generation of personal alcohol breath testing devices pair with smartphones. While some of these devices were found to be relatively accurate, others may mislead users into thinking that they are fit to drive, according to a new study. The latest generation of personal alcohol breath testing devices pair with smartphones. While some of…
