Published Subduction zone splay faults compound hazards of great earthquakes
(via sciencedaily.com) Original source Groundbreaking research has provided new insight into the tectonic plate shifts that create some of the Earth's largest earthquakes and tsunamis.
Published Record low Antarctic sea ice 'extremely unlikely' without climate change
(via sciencedaily.com) Original source Scientists have found that the record-low levels of sea ice around Antarctica in 2023 were extremely unlikely to happen without the influence of climate change. This low was a one-in-a-2000-year event without climate change and four times more likely under its effects.
Published After hundreds of years, study confirms Bermuda now home to cownose rays
(via sciencedaily.com) Original source Using citizen science, photographs, on-water observations and the combination of morphological and genetic data, researchers have provided evidence that the Atlantic cownose ray has recently made a new home in Bermuda. Results show that after hundreds of years of natural history records, this is a novel migration of Atlantic cownose rays to Bermuda.
Published Expanding on the fundamental principles of liquid movement
(via sciencedaily.com) Original source We are living in a world surrounded by liquid and flow, and understanding the principles that govern its movement is vital in our high-tech world. Through mathematical modeling and experimentation, researchers have expanded on Tanner's Law -- a law in fluid dynamics that describes how non-volatile liquids move across surfaces -- to cover a wider range of volatile liquids. These findings have the potential to play a role in various liquid-based industries such as electronics cooling.
Published Ukraine war caused migrating eagles to deviate from their usual flight plan, study finds
(via sciencedaily.com) Original source When migrating through Ukraine in 2022, Greater Spotted Eagles were exposed to multiple conflict events that altered their migratory course, according to a new study.
Published Better medical record-keeping needed to fight antibiotic overuse
(via sciencedaily.com) Original source A lack of detailed record-keeping in clinics and emergency departments may be getting in the way of reducing the inappropriate use of antibiotics, a pair of new studies suggests. In one of the studies, about 10% of children and 35% of adults who got an antibiotic prescription during an office visit had no specific reason for the antibiotic in their record.
Published Modern plant enzyme partners with surprisingly ancient protein
(via sciencedaily.com) Original source Scientists have discovered that a protein responsible for the synthesis of a key plant material evolved much earlier than suspected. This new research explored the origin and evolution of the biochemical machinery that builds lignin, a structural component of plant cell walls with significant impacts on the clean energy industry.
Published Ion irradiation offers promise for 2D material probing
(via sciencedaily.com) Original source Two-dimensional materials such as graphene promise to form the basis of incredibly small and fast technologies, but this requires a detailed understanding of their electronic properties. New research demonstrates that fast electronic processes can be probed by irradiating the materials with ions first.
Published Scientists develop new geochemical 'fingerprint' to trace contaminants in fertilizer
(via sciencedaily.com) Original source An international team of scientists has revealed high levels of toxic metals in global phosphate fertilizers using a isotopic variants of the element strontium as a tracer to uncover metals in soil, groundwater and possibly the food chain.
Published Chronic wasting disease unlikely to move from animals to people
(via sciencedaily.com) Original source A new study of prion diseases, using a human cerebral organoid model, suggests there is a substantial species barrier preventing transmission of chronic wasting disease (CWD) from cervids -- deer, elk and moose -- to people. The findings are consistent with decades of similar research in animal models.
Published Physicists propose path to faster, more flexible robots
(via sciencedaily.com) Original source Physicists revealed a microscopic phenomenon that could greatly improve the performance of soft devices, such as agile flexible robots or microscopic capsules for drug delivery.
Published Scale matters in determining vulnerability of freshwater fish to climate changes
(via sciencedaily.com) Original source A team explored the influence the spatial extent of research -- the geographical coverage of data collected -- has on evaluating the sensitivity of different fish species to climate change.
Published Sweet taste receptor affects how glucose is handled metabolically by humans
(via sciencedaily.com) Original source The sweet-taste receptor might be the first stop in a metabolic surveillance system for sugar. The receptor is also expressed in certain intestinal cells, where it may facilitate glucose absorption and assimilation, as part of this system. A team found that stimulation and inhibition of the sweet receptor helps regulate glucose metabolism in humans and may have implications for managing such metabolic disorders as diabetes.
Published Scientists discover mechanism of sugar signaling in plants
(via sciencedaily.com) Original source A paper describes how the moving parts of a particular plant protein control whether plants can grow and make energy-intensive products such as oil -- or instead put in place a series of steps to conserve precious resources. The study focuses specifically on how the molecular machinery is regulated by a molecule that rises and falls with the level of sugar -- plants' main energy source.
Published Pagan-Christian trade networks supplied horses from overseas for the last horse sacrifices in Europe
(via sciencedaily.com) Original source Horses crossed the Baltic Sea in ships during the Late Viking Age and were sacrificed for funeral rituals. Studies on the remains of horses found at ancient burial sites in Russia and Lithuania show that they were brought overseas from Scandinavia utilizing expansive trade networks connecting the Viking world with the Byzantine and Arab Empires. Up to now, researchers had believed sacrificial horses were always locally-sourced stallions. But these results reveal horses from modern Sweden or Finland traveled up to 1,500 km across the Baltic Sea. The findings also show that the sex of the horse was not necessarily a factor in them being chosen for sacrifice, with genetic analysis showing one in three were mares.
Published World's smallest quantum light detector on a silicon chip
(via sciencedaily.com) Original source Researchers have made an important breakthrough in scaling quantum technology by integrating the world's tiniest quantum light detector onto a silicon chip.
Published How heatwaves are affecting Arctic phytoplankton
(via sciencedaily.com) Original source The basis of the marine food web in the Arctic, the phytoplankton, responds to heatwaves much differently than to constantly elevated temperatures. This has been found by the first targeted experiments on the topic. The phytoplankton's behavior primarily depends on the cooling phases after or between heatwaves.
Published A long-term ketogenic diet accumulates aged cells in normal tissues, study finds
(via sciencedaily.com) Original source New research finds that a continuous, long-term ketogenic diet may induce senescence, or aged, cells in normal tissues, with particular implications for heart and kidney function. But planned breaks from the diet could help in prevention.
Published Magnetic imprint on deconfined nuclear matter
(via sciencedaily.com) Original source Scientists have the first direct evidence that the powerful magnetic fields created in off-center collisions of atomic nuclei induce an electric current in 'deconfined' nuclear matter. The study used measurements of how charged particles are deflected when they emerge from the collisions. The study provides proof that the magnetic fields exist and offers a new way to measure electrical conductivity in quark-gluon plasma.
Published Differing values of nature can still lead to joined up goals for sustainability
(via sciencedaily.com) Original source Recognizing and respecting the different ways nature is valued can enable better environmental decision-making, according to new research.
