Published Updating our understanding of Earth's architecture
(via sciencedaily.com) New models that show how the continents were assembled are providing fresh insights into the history of the Earth and will help provide a better understanding of natural hazards like earthquakes and volcanoes.
Published Lab earthquakes show how grains at fault boundaries lead to major quakes
(via sciencedaily.com) In a 'seismological wind tunnel,' engineers demonstrate the impact of rock gouge -- ground-up rock along a fault boundary -- on earthquake propogation.
Published The link between temperature, dehydration and tectonic tremors in Alaska
(via sciencedaily.com) No one is at their best when they are dehydrated and that goes for tectonic plates too. Researchers using a thermomechanical model of the Alaska subduction zone indicates that plate dehydration is at its highest in the region where low-frequency tremors occur, suggesting that the expelled water contributes towards these seimic events. This improved understanding will contribute to better predictions of future earthquakes.
Published A 3400-year-old city emerges from the Tigris River
(via sciencedaily.com) Archaeologists have uncovered a 3400-year-old Mittani Empire-era city once located on the Tigris River. The settlement emerged from the waters of the Mosul reservoir early this year as water levels fell rapidly due to extreme drought in Iraq. The extensive city with a palace and several large buildings could be ancient Zakhiku -- believed to have been an important center in the Mittani Empire (ca. 1550-1350 BC).
Published Study evaluates how to eliminate telemedicine's virtual waiting room
(via sciencedaily.com) Researchers have conducted a 10-week study to evaluate how text messaging a link to patients when their doctor is ready provides a way to connect patients and doctors without relying on the virtual waiting room.
Published The history of Lake Cahuilla before the Salton Sea
(via sciencedaily.com) Lake Cahuilla went through many cycles of filling and drying out over thousands of years. A new study used radiocarbon dating to determine the timing of the last seven periods of filling during the Late Holocene. The research sheds light on both the history of human occupation in the area and its seismic past.
Published Arc volcanoes are wetter than previously thought, with scientific and economic implications
(via sciencedaily.com) The percentage of water in arc volcanoes, which form above subduction zones, may be far more than many previous studies have calculated. This increased amount of water has broad implications for understanding how Earth's lower crust forms, how magma erupts through the crust, and how economically important mineral ore deposits form, according to a new article.
Published Tsunami threats underestimated in current models
(via sciencedaily.com) USC researchers have found a correlation between tsunami severity and the width of the outer wedge -- the area between the continental shelf and deep trenches where large tsunamis emerge -- that helps explain how underwater seismic events generate large tsunamis.
Published Designers find better solutions with computer assistance, but sacrifice creative touch
(via sciencedaily.com) A computer-guided approach to design can propose more solutions and balance out human inexperience and design fixation.
Published Haptics device creates realistic virtual textures
(via sciencedaily.com) Tactile sensation is an incredibly important part of how humans perceive their reality. Haptics or devices that can produce extremely specific vibrations that can mimic the sensation of touch are a way to bring that third sense to life. However, as far as haptics have come, humans are incredibly particular about whether or not something feels 'right,' and virtual textures don't always hit the mark. Now, researchers have developed a new method for computers to achieve that true texture -- with the help of human beings. Called a preference-driven model, the framework uses our ability to distinguish between the details of certain textures as a tool in order to give these virtual counterparts a tune-up.
Published Virtual immune system roadmap unveiled
(via sciencedaily.com) Researchers have published a roadmap for creating a digital twin of the immune system. Patterned after digital twins used in industry to test innovations on a model, the digital twin would create a virtual immune system tailored to individuals. Physicians could use this model to develop precision treatments based on a person's genetics and personal history. It could answer questions why some people react differently to COVID-19 infection, for example, or design precise immunosuppressant therapy for transplant patients, or allow pharmaceutical companies to more quickly bring drugs to market.
Published Puzzling features deep in Earth's interior illuminated
(via sciencedaily.com) New research examines an unusual pocket of rock at the boundary layer with Earth's core, some three thousand kilometers beneath the surface.
Published Algorithms empower metalens design
(via sciencedaily.com) Researchers have developed a new method for designing large-scale metasurfaces that uses techniques of machine intelligence to generate designs automatically. The method will enable new metasurface designs that can make an impact on virtual or augmented reality, self-driving cars, and machine vision for embarked systems and satellites.
Published Eavesdroppers can hack 6G frequency with DIY metasurface
(via sciencedaily.com) Crafty hackers can make a tool to eavesdrop on some 6G wireless signals in as little as five minutes using office paper, an inkjet printer, a metallic foil transfer and a laminator.
Published Hunga volcano eruption provides an explosion of data
(via sciencedaily.com) The massive Jan. 15, 2022, eruption of the Hunga submarine volcano in the South Pacific Ocean created a variety of atmospheric wave types, including booms heard 6,200 miles away in Alaska. It also created an atmospheric pulse that caused an unusual tsunami-like disturbance that arrived at Pacific shores sooner than the actual tsunami.
Published Study finds realism a key factor in driving engagement with virtual reality videos
(via sciencedaily.com) A recent study finds that realism is a key factor in determining whether viewers engage with virtual reality videos -- and that engagement is itself a key factor in determining whether viewers are interested in watching VR videos in the future.
Published New research could provide earlier warning of tsunamis
(via sciencedaily.com) A new method of detecting mega earthquakes, which picks up on the gravity waves they generate by using deep-learning models, can estimate earthquake magnitude in real time and provide earlier warning of tsunamis.
Published Laser bursts drive extremely fast logic gates
(via sciencedaily.com) By clarifying the role of 'real' and 'virtual' charge carriers in laser-induced currents, researchers have taken a decisive step toward creating ultrafast computers.
Published Head, body, eye coordination conserved across animal kingdom
(via sciencedaily.com) Fruit flies synchronize the movements of their heads and bodies to stabilize their vision and fly effectively, according to researchers who utilized virtual-reality flight simulators. The finding appears to hold true in primates and other animals, the researchers say, indicating that animals evolved to move their eyes and bodies independently to conserve energy and improve performance. This understanding could inform the design of advanced mobile robots.
Published Lake Erie quakes triggered by shifting water levels? Study finds no smoking gun, urges further research
(via sciencedaily.com) In June 2019, a magnitude 4.0 earthquake occurred beneath Lake Erie just off the shoreline of Ohio, about 20 miles northeast of Cleveland.
