Published Record-breaking recovery of rocks that originated in Earth's mantle could reveal secrets of planet's history
(via sciencedaily.com) Original source Scientists have recovered the first long section of rocks that originated in the Earth's mantle, the layer below the crust and the planet's largest component. The rocks will help unravel the mantle's role in the origins of life on Earth, the volcanic activity generated when it melts, and how it drives the global cycles of important elements such as carbon and hydrogen.
Published X-ray imagery of vibrating diamond opens avenues for quantum sensing
(via sciencedaily.com) Original source Scientists at three research institutions capture the pulsing motion of atoms in diamond, uncovering the relationship between the diamond's strain and the behavior of the quantum information hosted within.
Published Water delivered to the mantle by aluminum enriched hydrated slabs?
(via sciencedaily.com) Original source Researchers found a notable effect of aluminum on the sound velocities of superhydrous phase B, a dense hydrous magnesium silicate and potential host of water in the deep Earth. Their results suggest that aluminous phase B could explain seismic velocity anomalies in the Earth's mantle transition region and uppermost lower mantle.
Published Scientists uncover hidden forces causing continents to rise
(via sciencedaily.com) Original source Scientists have answered one of the most puzzling questions in plate tectonics: how and why 'stable' parts of continents gradually rise to form some of the planet's greatest topographic features.
Published Greenland fossil discovery reveals increased risk of sea-level catastrophe
(via sciencedaily.com) Original source Seeds, twigs, and insect parts found under two miles of ice confirm Greenland's ice sheet melted in the recent past, the first direct evidence that the center -- not just the edges -- of the two-mile-deep ice melted away in the recent geological past. The new research indicates that the giant ice sheet is more fragile than scientists had realized until the last few years -- and reveals increased risk of sea-level catastrophe in a warmer future.
Published New model refutes leading theory on how Earth's continents formed
(via sciencedaily.com) Original source Computational modeling shows that plate tectonics weren't necessary for early continents.
Published How the rising earth in Antarctica will impact future sea level rise
(via sciencedaily.com) Original source The rising earth beneath the Antarctic Ice Sheet will likely become a major factor in future sea level rise, a new study suggests.
Published Link between global warming and rising sea levels
(via sciencedaily.com) Original source A new study suggests that Earth's natural forces could substantially reduce Antarctica's impact on rising sea levels, but only if carbon emissions are swiftly reduced in the coming decades. By the same token, if emissions continue on the current trajectory, Antarctic ice loss could lead to more future sea level rise than previously thought.
Published Stacked up against the rest
(via sciencedaily.com) Original source Scientists have hypothesized that moir excitons -- electron-hole pairs confined in moir interference fringes which overlap with slightly offset patterns -- may function as qubits in next-generation nano-semiconductors. However, due to diffraction limits, it has not been possible to focus light enough in measurements, causing optical interference from many moir excitons. To solve this, researchers have developed a new method of reducing these moir excitons to measure the quantum coherence time and realize quantum functionality.
Published Recent volcanic 'fires' in Iceland triggered by storage and melting in crust
(via sciencedaily.com) Original source Scientists have detected geochemical signatures of magma pooling and melting beneath the subsurface during the 'Fagradalsfjall Fires', that began on Iceland's Reykjanes peninsula in 2021. Samples show that the start of the eruption began with massive pooling of magma, contrasting initial hypothesis for magma ascent straight from the mantle.
Published Researchers develop general framework for designing quantum sensors
(via sciencedaily.com) Original source Researchers have designed a protocol for harnessing the power of quantum sensors. The protocol could give sensor designers the ability to fine-tune quantum systems to sense signals of interest, creating sensors that are vastly more sensitive than traditional sensors.
Published Breaking new ground for computing technologies with electron-hole crystals
(via sciencedaily.com) Original source A team developed a novel method to successfully visualise electron-hole crystals in an exotic quantum material. Their breakthrough could pave the way for new advancements in computing technologies, including in-memory and quantum computing.
Published A blue miracle: How sapphires formed in volcanoes
(via sciencedaily.com) Original source Sapphires are among the most precious gems, yet they consist solely of chemically 'contaminated' aluminum oxide, or corundum. It is widely assumed that these crystals with their characteristically blue color come from deep crustal rocks and accidentally ended up on the Earth's surface as magma ascended. Geoscientists have now been able to show that the sapphire grains found in the Eifel (Germany) formed in association with volcanism.
Published Researchers trap atoms, forcing them to serve as photonic transistors
(via sciencedaily.com) Original source Researchers have developed a means to realize cold-atom integrated nanophotonic circuits.
Published Optical fibers fit for the age of quantum computing
(via sciencedaily.com) Original source A new generation of specialty optical fibers has been developed by physicists to cope with the challenges of data transfer expected to arise in the future age of quantum computing.
Published Atomic 'GPS' elucidates movement during ultrafast material transitions
(via sciencedaily.com) Original source Scientists have created the first-ever atomic movies showing how atoms rearrange locally within a quantum material as it transitions from an insulator to a metal. With the help of these movies, the researchers discovered a new material phase that settles a years-long scientific debate and could facilitate the design of new transitioning materials with commercial applications.
Published 'Kink state' control may provide pathway to quantum electronics
(via sciencedaily.com) Original source The key to developing quantum electronics may have a few kinks. According to researchers, that's not a bad thing when it comes to the precise control needed to fabricate and operate such devices, including advanced sensors and lasers. The researchers fabricated a switch to turn on and off the presence of kink states, which are electrical conduction pathways at the edge of semiconducting materials.
