    • Cosmic adventure: Seeking space rocks in Olympic Coast National Marine Sanctuary 2019-05-31
      On March 7, 2018, a large meteorite broke up and fell into the ocean about 15 miles off the coast of Washington into NOAA’s Olympic Coast National Marine Sanctuary. Eyewitnesses from nearby areas including Quinault Indian Nation and Grays Harbor County reported a bright flash in the sky and sonic booms loud enough to shake […]
    • Cordell Bank National Marine Sanctuary celebrates 30 years of ocean protection 2019-05-29
      Twenty-two miles offshore of the northern California coastline is a patch of ocean that looks ordinary to the uninformed eye. But beneath the surface of the deep blue Pacific, a towering undersea block of granite crowded with marine life rises up from the gloom of the depths. Cordell Bank hosts throngs of fish, invertebrates, and […]
    • New deep-sea coral species discovered in Cordell Bank National Marine Sanctuary 2019-05-15
      Dozens of deep-sea corals thrive off the California coast, but many are still unknown to science. Scientists recently described a new species of deep-sea coral found 22 miles west of Point Reyes National Seashore. The small, yellow octocoral has been named Chromoplexaura cordellbankensis for its discovery on Cordell Bank, a 26 square-mile rocky, underwater feature […]

    • 2019/11/14 DARPA’s Angler Program Awards Contracts to Advance Autonomous Underwater Systems 2019-11-14
      DARPA has awarded six contracts for work on the Angler program, which aims to pioneer the next generation of autonomous underwater robotic systems capable of physical intervention in the deep ocean environment. This class of future unmanned underwater vehicles (UUVs) must overcome reliance on GPS and human intervention to support infrastructure establishment, maintenance, and resilience […]
    • 2019/11/12 Subterranean Challenge Identifies Urban Circuit Location, Updates Prize Amounts 2019-11-12
      The DARPA Subterranean (SubT) Challenge Urban Circuit will take place Feb. 18-27, 2020, at Satsop Business Park west of Olympia, Washington. In the SubT Challenge, teams deploy autonomous ground and aerial systems to attempt to map, identify, and report artifacts along two competition courses. The artifacts represent items a first responder or service member may […]
    • 2019/10/30 Teams Complete SubT Challenge Virtual Tunnel Circuit 2019-10-30
      With 50 total points, Coordinated Robotics finished in first place in the DARPA Subterranean (SubT) Challenge Virtual Tunnel Circuit event, and as the top self-funded team, earned $250,000. Eight teams developed, tested, and submitted their software-based solutions for simulation-based evaluation on the SubT Virtual Testbed.

    • France reverse palm oil tax break after outcry 2019-11-15
      France's parliament on Friday voted down a proposed tax break on palm oil—which would have hugely benefited energy giant Total—after lawmakers and environmental activists complained the legislation had been rushed through the day before without proper debate.
    • Research sheds light on the underlying mechanics of soft filaments 2019-11-15
      Artificial muscles will power the soft robots and wearable devices of the future. But more needs to be understood about the underlying mechanics of these powerful structures in order to design and build new devices.
    • A marvelous molecular machine 2019-11-15
      Squids, octopuses and cuttlefish are undisputed masters of deception and camouflage. Their extraordinary ability to change color, texture and shape is unrivaled, even by modern technology.

    • Hot electrons harvested without tricks 2019-11-15
      Semiconductors convert energy from photons (light) into an electron current. However, some photons carry too much energy for the material to absorb. These photons produce "hot electrons," and the excess energy of these electrons is converted into heat. Materials scientists have been looking for ways to harvest this excess energy. Scientists from the University of […]
    • Scientists develop near ambient pressure photoemission electron microscopy 2019-11-15
      A research group led by Prof. Fu Qiang and Prof. Bao Xinhe at the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS) have developed near ambient pressure photoemission electron microscopy (AP-PEEM) with a tunable deep-ultraviolet (DUV) laser source as the excitation source.

    • Nearly extreme black holes which attempt to regrow hair become bald again 2019-11-15
      Black holes 'have no hair': no attributes that can be used to tell them apart. Extreme black holes (spinning at maximally allowed rate) can have an additional property, permanent hair that is made of a massless scalar field. Nearly extreme black holes (like Gargantua, the black hole featured in the movie "Interstellar") have hair that […]

      The direction in which a galaxy spins depends on its mass, researchers have found.
    • Image: Hubble spots a curious spiral 2019-11-15
      The universe is simply so vast that it can be difficult to maintain a sense of scale. Many galaxies we see through telescopes such as the NASA/ESA Hubble Space Telescope, the source of this beautiful image, look relatively similar: spiraling arms, a glowing center, and a mixture of bright specks of star formation and dark […]

    • Atomically dispersed Ni is coke-resistant for dry reforming of methane 2019-11-15
      Dry reforming of methane (DRM) is the process of converting methane (CH4) and carbon dioxide (CO2) into synthesis gas (syngas). Since CO2 and CH4 are the two most important atmospheric greenhouse gases (GHGs), as well as abundant and low-cost carbon sources, DRM has the potential to mitigate rising GHG emissions and simultaneously realize clean(er) fossil […]
    • Water could modulate the activity and selectivity of carbon dioxide reduction 2019-11-15
      As an alternative to the depletion of fossil resources, the reduction of CO2 emitted from fossil fuel combustion into valuable chemicals and fuel has drawn increasing attention. Due to the highly thermodynamic stability of CO2, it is still very challenging to find a sustainable and cost-efficient route to selectively convert inert CO2 at a high […]

    • Bacterial protein impairs important cellular processes 2019-11-15
      Areas of skin that have been damaged by an injury are ideal niches for the concentration of Pseudomonas aeruginosa, a bacterium which impairs the healing process in tissue and creates favorable conditions for infections. Because of its resistance to most available antibiotics, this bacterium is in the "Priority 1 / CRITICAL" category of the World […]
    • A review of the lesser known sides of the plant genus Erythroxylum 2019-11-15
      Since the Western world came across the South American plant genus Erythroxylum, the use of this multifaceted genus has been associated with the production of soft drinks, such as Coca Cola, or with the abuse of the purified plant substance in the form of the narcotic cocaine. However, the indigenous peoples of South America have […]
    • eDNA reveals where endangered birds of a feather flock together 2019-11-15
      For the first time, Australian scientists have shown that environmental DNA (eDNA) can be used to detect the presence of an endangered bird species simply by collecting a cupful of water from the pools where they drink.
