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 Earthquake lab experiments produce aftershock-like behavior
(via sciencedaily.com) Earthquakes are notoriously hard to predict, and so too are the usually less-severe aftershocks that often follow a major seismic event.
Published Physicists observe wormhole dynamics using a quantum computer
(via sciencedaily.com) Original source Scientists have developed a quantum experiment that allows them to study the dynamics, or behavior, of a special kind of theoretical wormhole.
Published 'Digital footprints' central to new approach for studying post-disturbance recreation changes
(via sciencedaily.com) A new social media-based study of recreation visitation in the Gorge following the Eagle Creek Fire expands on research launched in 2016 -- and holds promise for other large, multi-ownership landscapes. The study shows how using new approaches that draw from social media data can help us better understand the complex relationships between wildfire, natural resource management, and people.
Published Stabilizing lithium-ion batteries with microbially synthesized electrolyte additive
(via sciencedaily.com) Lithium-ion batteries with high-energy-density cathodes are necessary to meet the energy demands of next-generation electronics and electric vehicles. At high voltages, however, the battery electrolyte undergoes excessive decomposition, compromising cathode performance. To tackle this, researchers have now synthesized a bio-based, non-toxic additive material that stabilizes the cathode by forming a passivation layer on its surface and suppressing its decomposition. Eco-friendly and low-cost, the novel compound could promote a wider utilization of bio-based resources.
Published Pulses driven by artificial intelligence tame quantum systems
(via sciencedaily.com) Original source Machine learning drives self-discovery of pulses that stabilize quantum systems in the face of environmental noise.
Published Large terrestrial mammals are more vulnerable to the acoustic impact of drones than to the visual impact, study finds
(via sciencedaily.com) Original source Large terrestrial mammals are vulnerable to the acoustic sounds of drones, technological systems which are increasingly used to study the wildlife in open habitats such as the savanna and marshes, according to a new study.
Published Team recycles previously unrecyclable plastic
(via sciencedaily.com) Researchers have discovered a way to chemically recycle PVC into usable material, finding a way to use the phthalates in the plasticizers -- one of PVC's most noxious components -- as the mediator for the chemical reaction.
Published Small asteroids are probably young
(via sciencedaily.com) Original source The impact experiment conducted on the asteroid Ryugu by the Japanese Hayabusa2 mission which took place two years ago resulted in an unexpectedly large crater. With the use of simulations, a team has recently succeeded in gaining new insights from the experiment regarding the formation and development of asteroids.
Published Crowding makes time seem to pass more slowly
(via sciencedaily.com) Testing time perception in an unusually lifelike setting -- a virtual reality ride on a New York City subway train -- an interdisciplinary research team found that crowding makes time seem to pass more slowly.
Published Ancient DNA from medieval Germany tells the origin story of Ashkenazi Jews
(via sciencedaily.com) Extracting ancient DNA from teeth, an international group of scientists peered into the lives of a once-thriving medieval Ashkenazi Jewish community in Erfurt, Germany. The findings show that the Erfurt Jewish community was more genetically diverse than modern day Ashkenazi Jews.
Published Rare sighting of luminous jet spewed by supermassive black hole
(via sciencedaily.com) Astronomers discover a bright optical flare caused by a dying star's encounter with a supermassive black hole.
Published Fossil overturns more than a century of knowledge about the origin of modern birds
(via sciencedaily.com) Fossilized fragments of a skeleton, hidden within a rock the size of a grapefruit, have helped upend one of the longest-standing assumptions about the origins of modern birds.
Published Mysteriously bright flash is a black hole jet pointing straight toward Earth, astronomers say
(via sciencedaily.com) Astronomers have determined the source of an incredibly bright X-ray, optical and radio signal appearing from halfway across the Universe.
Published Mammoth problem with extinction timeline
(via sciencedaily.com) Original source Paleontologists say environmental DNA is not always helpful in identifying when animals like mammoths went extinct because genetic material found in sediment could have come from animals that died thousands of years earlier.
Published Antibiotics' effect on the mycobiome varies from person to person
(via sciencedaily.com) Antibiotic treatment disrupts the balance of beneficial and harmful bacteria in a person's gut. That disruption can lead to the overgrowth of fungal species in the gut mycobiota, including the common intestinal yeast Candida albicans. However, researchers only have a limited understanding of the underlying mechanisms. Researchers now report on how treatment with a common beta-lactam antibiotic led to significant changes in C. albicans in patients.
Published Researchers introduce an energy-efficient method to enhance thermal conductivity of polymer composites
(via sciencedaily.com) Thermally conductive polymer composites consist of fillers oriented in certain directions that form pathways for heat flow. However, conventional methods to control the orientation of these fillers are energy-intensive and require surface modifications that can deteriorate the quality and properties of these materials. Now, researchers have developed an energy-efficient method to control the orientation of the fillers without the need for surface modification, resulting in improvement in thermal conductivity.
Published New quantum computing feat is a modern twist on a 150-year-old thought experiment
(via sciencedaily.com) New research demonstrates a 20x improvement in resetting a quantum bit to its '0' state, using a modern version of the 'Maxwell's demon'.
Published Major fires an increasing risk as the air gets thirstier, research shows
(via sciencedaily.com) Greater atmospheric demand for water means a dramatic increase in the risk of major fires in global forests unless we take urgent and effective climate action, new research finds. Researchers have examined global climate and fire records in all of the world's forests over the last 20 years.
Published Making 'transport' robots smarter
(via sciencedaily.com) Imagine a team of humans and robots working together to process online orders -- real-life workers strategically positioned among their automated coworkers who are moving intelligently back and forth in a warehouse space, picking items for shipping to the customer. This could become a reality sooner than later, thanks to researchers who are working to speed up the online delivery process by developing a software model designed to make 'transport' robots smarter.
