Published New map shows where damaging earthquakes are most likely to occur in US
(via sciencedaily.com) Original source Scientists recently revealed the latest National Seismic Hazard Model, showing that nearly 75% of the United States could experience a damaging earthquake, emphasizing seismic hazards span a significant part of the country.
Published Solid-state qubits: Forget about being clean, embrace mess
(via sciencedaily.com) Original source New findings debunk previous wisdom that solid-state qubits need to be super dilute in an ultra-clean material to achieve long lifetimes. Instead, cram lots of rare-earth ions into a crystal and some will form pairs that act as highly coherent qubits, a new paper shows.
Published Is natural spa water a fossil of water? Uncover the real ultra-deep water cycles
(via sciencedaily.com) Original source Researchers have made a groundbreaking discovery regarding the origins of non-meteoric water in natural spa waters located in central Japan. Based on numerical modeling, their results suggest that this water has been confined within the lithosphere for an extensive period of 1.5-5 million years. They identified three primary sources for this ancient water: the Philippine Sea Plate, the Pacific Plate, and ancient seafloor sediments, particularly in the Niigata and southwest Gunma regions.
Published Seismic and infrasonic signals used to characterize Nord Stream pipeline events
(via sciencedaily.com) Original source A new study provides further evidence that the Nord Stream seismic signals came from a complex source. The signals lasted longer than would be expected from a single explosive source, the researchers say, and were more like the signals detected from an underwater volcano or a pipeline venting gas.
Published Machine learning boosts search for new materials
(via sciencedaily.com) Original source During X-ray diffraction experiments, bright lasers shine on a sample, producing diffracted images that contain important information about the material's structure and properties. But conventional methods of analyzing these images can be contentious, time-consuming, and often ineffective, so scientists are developing deep learning models to better leverage the data.
Published Morocco earthquake had unusual deep slip, according to new modeling
(via sciencedaily.com) Original source In their rapid characterization of the magnitude 6.8 Al Haouz earthquake in Morocco, researchers suggest that the earthquake ruptured roughly 25 kilometers deep beneath the surface.
Published Newly developed material gulps down hydrogen, spits it out, protects fusion reactor walls
(via sciencedaily.com) Original source A recent advance could enable more efficient compact fusion reactors that are easier to repair and maintain.
Published Was the earthquake induced or natural? New study tests frameworks to answer the question
(via sciencedaily.com) Original source Using questionnaires created to determine whether a particular earthquake is natural or induced by human activity, a panel of experts concluded that the November 2022 magnitude 5.2 Peace River earthquake sequence in Alberta, Canada was likely to be induced.
Published Extracting uranium from seawater as another source of nuclear fuel
(via sciencedaily.com) Original source Oceans cover most of Earth's surface and support a staggering number of lifeforms, but they're also home to a dilute population of uranium ions. And -- if we can get these particular ions out of the water -- they could be a sustainable fuel source to generate nuclear power. Researchers have now developed a material to use with electrochemical extraction that attracts hard-to-get uranium ions from seawater more efficiently than existing methods.
Published New geophysical technique enhances imaging of fluid-filled rocks finding connections with microearthquakes
(via sciencedaily.com) Original source Scientists have recently introduced a new method called ambient noise differential adjoint tomography, which allows researchers to visualise rocks with fluids better, leading to potential advancements in the discovery of water and oil resources, as well as applications in urban geologic hazard and early warning systems for tsunamis and the understanding of the water cycle.
Published Ancient stars made extraordinarily heavy elements
(via sciencedaily.com) Original source How heavy can an element be? An international team of researchers has found that ancient stars were capable of producing elements with atomic masses greater than 260, heavier than any element on the periodic table found naturally on Earth. The finding deepens our understanding of element formation in stars.
Published Recycling concrete using carbon can reduce emissions and waste
(via sciencedaily.com) Original source Amid the rubble of large-sale earthquake, war or other disaster -- and as ageing buildings and infrastructure are replaced -- mountains of concrete are often taken to landfill or pounded into rubble for roads. For a more sustainable approach, experts are developing a 'value add' for old broken concrete to 'upcycling' coarse aggregate to produce a strong, durable and workable concrete using a small amount of a secret ingredient -- graphene.
Published Revolutionary breakthrough in the manufacture of photovoltaic cells
(via sciencedaily.com) Original source Engineers have achieved a world first by manufacturing the first back-contact micrometric photovoltaic cells.
Published Nuclear expansion failure shows simulations require change
(via sciencedaily.com) Original source A team of researchers looked back at a model that predicted nuclear power would expand dramatically in order to assess the efficacy of energy policies implemented today.
Published A novel system for slip prevention of unmanned rovers
(via sciencedaily.com) Original source Planetary rovers, which help humanity explore other planets, can deviate from their targeted paths or get stuck due to slipping on loose soil. To combat this problem, researchers have developed a novel system for rovers to detect their slip condition from the change in the shape of their chassis. This novel technology, inspired by human muscles, can lead to advanced sensing technologies that make travel safer for unmanned vehicles.
Published Some of today's earthquakes may be aftershocks from quakes in the 1800s
(via sciencedaily.com) Original source In the 1800s, some of the strongest earthquakes in recorded U.S. history struck North America's continental interior. Almost two centuries later, the central and eastern United States may still be experiencing aftershocks from those events, a new study finds.
Published New dates for landslides reveal past Seattle fault earthquakes
(via sciencedaily.com) Original source New maps of more than 1,000 deep-seated landslides in the Puget Lowlands of Washington State provide evidence of the last major earthquake along the Seattle Fault about 1,100 years ago -- and may also hold traces of older earthquakes along the fault.
Published Milestone moment toward development of nuclear clock
(via sciencedaily.com) Original source Physicists have started the countdown on developing a new generation of timepieces capable of shattering records by providing accuracy of up to one second in 300 billion years, or about 22 times the age of the universe.
Published Hebrew prayer book fills gap in Italian earthquake history
(via sciencedaily.com) Original source The chance discovery of a note written in a 15th century Hebrew prayer book fills an important gap in the historical Italian earthquake record, offering a brief glimpse of a previously unknown earthquake affecting the Marche region in the central Apennines.
Published The remains of an ancient planet lie deep within Earth
(via sciencedaily.com) Original source The remnants of an ancient planet that collided with Earth to form the Moon lie deep within the earth, according to a new model.
