Published North Sea oil and gas extraction spikes pollution by 10,000 percent, study finds
(via sciencedaily.com) Original source North Sea oil and gas extraction can cause pollution to spike by more than 10,000 percent within half a kilometer around off-shore sites, a study has found. The research has uncovered the true impact on Britain's seabed life -- with the number of species plummeting nearly 30 percent near platforms.

(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 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.
Published Quantum sensor for the atomic world
(via sciencedaily.com) Original source In a scientific breakthrough, an international research team has developed a quantum sensor capable of detecting minute magnetic fields at the atomic length scale. This pioneering work realizes a long-held dream of scientists: an MRI-like tool for quantum materials.
Published Nonreciprocal interactions go nonlinear
(via sciencedaily.com) Original source Using two optically trapped glass nanoparticles, researchers observed a novel collective Non-Hermitian and nonlinear dynamic driven by nonreciprocal interactions. This contribution expands traditional optical levitation with tweezer arrays by incorporating the so called non-conservative interactions.
Published Warming has more impact than cooling on Greenland's 'firn'
(via sciencedaily.com) Original source A new study finds disproportionate effects of temperature shifts on an icy glacier layer.
Published Spin qubits go trampolining
(via sciencedaily.com) Original source Researchers have developed somersaulting spin qubits for universal quantum logic. This achievement may enable efficient control of large semiconductor qubit arrays. The research group recently published their demonstration of hopping spins and somersaulting spins.
Published How Saharan dust regulates hurricane rainfall
(via sciencedaily.com) Original source New research underscores the close relationship between dust plumes transported from the Sahara Desert in Africa, and rainfall from tropical cyclones along the U.S. Gulf Coast and Florida.
Published Southern Ocean absorbing more carbon dioxide than previously thought, study finds
(via sciencedaily.com) Original source New research has found that the Southern Ocean absorbs more carbon dioxide (CO2) than previously thought. Using direct measurements of CO2 exchange, or fluxes, between the air and sea, the scientists found the ocean around Antarctica absorbs 25% more CO2 than previous indirect estimates based on shipboard data have suggested.
Published The ocean is becoming too loud for oysters, research finds
(via sciencedaily.com) Original source Baby oysters rely on natural acoustic cues to settle in specific environments, but new research reveals that noise from human activity is interfering with this critical process.
Published Researchers record images and data of a shark experiencing a boat strike
(via sciencedaily.com) Original source Researchers have captured what they believe is the first ever video of a shark or any large marine animal being struck by a boat.
Published Whale shark tracked for record-breaking four years
(via sciencedaily.com) Original source Researchers have been tracking a 26-foot endangered whale shark -- named 'Rio Lady' -- with a satellite transmitter for more than four years -- a record for whale sharks and one of the longest tracking endeavors for any species of shark.
Published Ecologists discover rare fiddler crab species on Hong Kong coast highlighting the impact of climate change and coastal development
(via sciencedaily.com) Original source Researchers have made an exciting discovery on the Hong Kong coast. They have identified two fiddler crab species: Tubuca dussumieri, previously recorded in old literature but never confirmed in recent times, and Tubuca. coarctata, which has never been seen in Hong Kong. These findings not only confirm the presence of these insular species in Hong Kong but also explore the potential impact of climate change on their distribution.
Published Deep-ocean floor produces its own oxygen
(via sciencedaily.com) Original source An international team of researchers has discovered that metallic minerals on the deep-ocean floor produce oxygen -- 13,000 feet below the surface. Discovery challenges long-held assumptions that only photosynthetic organisms generate Earth's oxygen. Minerals at the abyssal seafloor appear to act like geobatteries to produce oxygen in a process that does not require sunlight.
Published Sea ice's cooling power is waning faster than its area of extent
(via sciencedaily.com) Original source As sea ice disappears and grows less reflective, the Arctic has lost around a quarter of its cooling power since 1980, and the world has lost up to 15%, according to new research.
Published Reef pest feasts on 'sea sawdust'
(via sciencedaily.com) Original source Researchers have uncovered an under the sea phenomenon where coral-destroying crown-of-thorns starfish larvae have been feasting on blue-green algae bacteria known as 'sea sawdust'.
Published Diatom surprise could rewrite the global carbon cycle
(via sciencedaily.com) Original source When it comes to diatoms that live in the ocean, new research suggests that photosynthesis is not the only strategy for accumulating carbon. Instead, these single-celled plankton are also building biomass by feeding directly on organic carbon in wide swaths of the ocean. These new findings could lead to reduced estimates regarding how much carbon dioxide diatoms pull out of the air via photosynthesis, which in turn, could alter our understanding of the global carbon cycle, which is especially relevant given the changing climate.
