Published Researchers explore why some people get motion sick playing VR games while others don't
(via sciencedaily.com) Original source The way our senses adjust while playing high-intensity virtual reality games plays a critical role in understanding why some people experience severe cybersickness and others don't.
Published Coastal species persist on high seas on floating plastic debris
(via sciencedaily.com) Original source The high seas have been colonized by a surprising number of coastal marine invertebrate species, which can now survive and reproduce in the open ocean, contributing strongly to the floating community composition. Researchers found coastal species, representing diverse taxonomic groups and life history traits, in the eastern North Pacific Subtropical Gyre on over 70 percent of the plastic debris they examined. Further, the debris carried more coastal species than open ocean species.
Published Increased droughts are disrupting carbon-capturing soil microbes, concerning ecologists
(via sciencedaily.com) Original source Soil stores more carbon than plants and the atmosphere combined, and soil microbes are largely responsible for putting it there. However, the increasing frequency and severity of drought, such as those that have been impacting California, could disrupt this delicate ecosystem. Microbial ecologists warn that soil health and future greenhouse gas levels could be impacted if soil microbes adapt to drought faster than plants do.
Published Some coastal salt marshes are keeping up with sea level rise -- for now
(via sciencedaily.com) The world's salty, tidal marshes are hotspots of carbon storage and productivity, building up sediments and plant material to stay above sea level. However, as sea level rises at an increasing rate, scientists debate whether it's possible for wetlands to win the race. New research reveals how salt marshes along the U.S. East Coast have responded to accelerating sea level rise by building elevation more quickly to keep pace with the sea over the last century.
Published East Coast, US, landslide impacts from Puerto Rico to Vermont and in between
(via sciencedaily.com) In the U.S., we may often think of landslides as primarily a West Coast problem, mostly plaguing the mountainous terrain of California, Oregon, and Washington. New research highlights the major impacts of landslides on the U.S. East Coast and what is being done to save lives and deal with the damages.
Published Mississippi River Delta study reveals which human actions contribute to land loss
(via sciencedaily.com) Scientists reveal new information about the role humans have played in large-scale land loss in the Mississippi River Delta -- crucial information in determining solutions to the crisis.
Published Scholars unify color systems using prime numbers
(via sciencedaily.com) Existing color systems, such as RGB and CYMK, are all text-based and require a large range of values to represent different colors, making them difficult to compute and time-consuming to convert. Recently, researchers made a breakthrough by inventing an innovative color system, called 'C235', based on prime numbers, enabling efficient encoding and effective color compression. It can unify existing color systems and has the potential to be applied in various applications, like designing an energy-saving LCD system and colorizing DNA codons.
Published Reassessment of Storegga event: Second major landslide recognized
(via sciencedaily.com) Submarine landslides have a large tsunami potential and occurred on the central Norwegian shelf more frequently in the past than previously thought. Scientists investigate the Nyegga landslide off the coast of Norway. The submarine landslide occurred in the same area as the well-known Storegga event 8,150 years ago. The new findings suggest that approximately one-third of the seafloor material missing -- previously attributed to the Storegga event -- was removed by the Nyegga event 20,000 years ago. This raises questions about the frequency of large submarine landslides and their associated tsunami hazard.
Published Chromo-encryption method encodes secrets with color
(via sciencedaily.com) In a new approach to security that unites technology and art, E researchers have combined silver nanostructures with polarized light to yield a range of brilliant colors, which can be used to encode messages.
Published Video game playing causes no harm to young children's cognitive abilities, study finds
(via sciencedaily.com) Despite old fears that bad effects follow excessive video game playing or questionable game choices, researchers found those factors mattered little, if any, in children's brain health. The bad news? Video games assumed to be effective learning tools showed no meaningful effects, either.
Published A changing flood recipe for Las Vegas
(via sciencedaily.com) Las Vegas, with its rapid urbanization and desert landscape, is highly vulnerable to flooding. For this reason, flood managers have built an extensive system of drainage ditches and detention basins to protect the public. Now, a new study shows how intentional engineering and urban development are interacting with climate change to alter the timing and intensity of flood risk.
Published Most plastic debris on Seychelles beaches comes from far-off sources
(via sciencedaily.com) A new modelling study shows that the Seychelles and other islands in the western Indian Ocean are not responsible for most of the plastic waste that accumulates on their beaches. Indonesia, India, and Sri Lanka were found to be the main sources of land-based plastic debris. The Seychelles also accumulate significant amounts of plastic debris of marine origin from fisheries and shipping lanes. • The results highlight the urgent need for a legally-binding Global Plastics Treaty and greater enforcement of regional policies to reduce plastic waste.
Published Purchasing loot boxes in video games associated with problem gambling risk, says study
(via sciencedaily.com) Gamers who buy 'loot boxes' are up to two times more likely to gamble, shows new research.
Published Study shows landbuilding, site of freshwater diversion
(via sciencedaily.com) Supporters of the large-scale Mississippi River sediment diversions currently being planned by the Louisiana Coastal Protection and Restoration Authority got a boost to their case recently when scientists published an analysis of two existing freshwater diversions on the state's coastline, one of which shows a significant amount of land having formed over the past 17 years.
Published Landslide risk remains years after even a weak earthquake
(via sciencedaily.com) Satellite observations have revealed that weak seismic ground shaking can trigger powerful landslide acceleration -- even several years after a significant earthquake.
Published Online gaming enhances career prospects and develops soft skills, finds new study
(via sciencedaily.com) Online gaming behavior can encourage gamers to gain a variety of soft skills which could assist them with training to support their career aspirations, according to new research.
Published Microlaser chip adds new dimensions to quantum communication
(via sciencedaily.com) With only two levels of superposition, the qubits used in today's quantum communication technologies have limited storage space and low tolerance for interference. Engineering's hyperdimensional microlaser generates 'qudits,' photons with four simultaneous levels of information. The increase in dimension makes for robust quantum communication technology better suited for real-world applications.
Published Satellites cast critical eye on coastal dead zones
(via sciencedaily.com) Scientists have found a new and better way to use remote sensing to understand where coastal dead zones are and predict changes.
Published Using 1980s environmental modeling to mitigate future disasters: Could Japan's 3/11 disaster have been prevented?
(via sciencedaily.com) On March 11, 2011, multiple catastrophes in Japan were triggered by the Great East Japan Earthquake, including the nuclear accident at the Fukushima Daiichi Nuclear Power Plant. This event, also known as the 3/11 disaster, is what is known as a compound disaster. Now that over a decade has passed since this event, researchers are investigating how to prevent the next compound disaster.
Published Report outlines plans for major research effort on subduction zone geologic hazards
(via sciencedaily.com) Subduction zones, where one tectonic plate slides beneath another, produce the most devastating seismic, volcanic, and landslide hazards on the planet. A new report presents an ambitious plan to make major advances in understanding subduction zone hazards by bringing together a diverse community of scientists in a long-term collaborative effort, deploying new instrumentation in subduction zones, and developing more sophisticated and accurate models.
