Published Engineers bring efficient optical neural networks into focus
(via sciencedaily.com) Original source Researchers have published a programmable framework that overcomes a key computational bottleneck of optics-based artificial intelligence systems. In a series of image classification experiments, they used scattered light from a low-power laser to perform accurate, scalable computations using a fraction of the energy of electronics.
Published Millions of years for plants to recover from global warming
(via sciencedaily.com) Original source Catastrophic volcanic eruptions that warmed the planet millions of years ago shed new light on how plants evolve and regulate climate. Researchers reveal the long-term effects of disturbed natural ecosystems on climate in geological history and its implications for today.
Published Achieving quantum memory in the hard X-ray range
(via sciencedaily.com) Original source Physicists have used Doppler-shifted nuclear resonant absorbers to form a nuclear frequency comb, enabling a quantum memory in the notoriously difficult X-ray range.
Published New technology uses light to engrave erasable 3D images
(via sciencedaily.com) Original source Researchers invented a technique that uses a specialized light projector and a photosensitive chemical additive to imprint two- and three-dimensional images inside any polymer. The light-based engraving remains in the polymer until heat or light are applied, which erases the image and makes it ready to use again. The technology is intended for any situation where having detailed, precise visual data in a compact and easily customizable format could be critical, such as planning surgeries and developing architectural designs.
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 Artificial compound eye to revolutionize robotic vision at lower cost but higher sensitivity
(via sciencedaily.com) Original source A research team has recently developed a novel artificial compound eye system that is not only more cost-effective, but demonstrates a sensitivity at least twice that of existing market products in small areas. The system promises to revolutionize robotic vision, enhance robots' abilities in navigation, perception and decision-making, while promoting commercial application and further development in human-robot collaboration.
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 Turning unused signals such as Wi-Fi into energy for electronics
(via sciencedaily.com) Original source We are constantly surrounded by electromagnetic waves such as Wi-Fi. Researchers tested a device to convert this ambient energy into energy for electronic devices.
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 Physicists develop new method to combine conventional internet with the quantum internet
(via sciencedaily.com) Original source Researchers send entangled photons and laser pulses of the same color over a single optical fiber for the first time.
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 Modern behavior explains prehistoric economies
(via sciencedaily.com) Original source What if the 'Market Economy' always existed? Archaeologists tried to answer this question by researching how much Bronze Age people used to spend to sustain their daily lives. Their results show that, starting at least 3,500 years ago, the spending habits of prehistoric Europeans were not substantially different from what they are today.
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 Bright prospects for engineering quantum light
(via sciencedaily.com) Original source Computers benefit greatly from being connected to the internet, so we might ask: What good is a quantum computer without a quantum internet?
Published Super-black wood can improve telescopes, optical devices and consumer goods
(via sciencedaily.com) Original source Thanks to an accidental discovery, researchers have created a new super-black material that absorbs almost all light, opening potential applications in fine jewelry, solar cells and precision optical devices.
Published Breaking MAD: Generative AI could break the internet, researchers find
(via sciencedaily.com) Original source Researchers have found that training successive generations of generative artificial intelligence models on synthetic data gives rise to self-consuming feedback loops.
