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.
Published Powerful new particle accelerator a step closer with muon-marshalling technology
(via sciencedaily.com) Original source New experimental results show particles called muons can be corralled into beams suitable for high-energy collisions, paving the way for new physics.
Published Physicists develop new theory describing the energy landscape formed when quantum particles gather together
(via sciencedaily.com) Original source An international team of physicists has proven new theorems in quantum mechanics that describe the 'energy landscapes' of collections of quantum particles. Their work addresses decades-old questions, opening up new routes to make computer simulation of materials much more accurate. This, in turn, may help scientists design a suite of materials that could revolutionize green technologies.
Published Paving the way to extremely fast, compact computer memory
(via sciencedaily.com) Original source Researchers have demonstrated that the layered multiferroic material nickel iodide (NiI2) may be the best candidate yet for devices such as magnetic computer memory that are extremely fast and compact. Specifically, they found that NiI2 has greater magnetoelectric coupling than any known material of its kind.
Published Microplastic pollution increases sea foam height and stability
(via sciencedaily.com) Original source Researchers examine the specific impacts of microplastics on the geophysics of sea foam formation in the critical zone where water meets air in the top layer of the ocean. They devised two simulations for their work -- a column filled with sea water injected with air and a laboratory-scale breaking wave channel to test the impacts of wave height on sea foam in the surface microlayer -- and tested their effects on sea foam formation, stability, and duration.
Published Breakthrough in quantum microscopy: Researchers are making electrons visible in slow motion
(via sciencedaily.com) Original source Physicists are developing quantum microscopy which enables them for the first time to record the movement of electrons at the atomic level with both extremely high spatial and temporal resolution. Their method has the potential to enable scientists to develop materials in a much more targeted way than before.
Published High and low tide cause low and high methane fluxes
(via sciencedaily.com) Original source Methane, a strong greenhouse gas that naturally escapes from the bottom of the North Sea, is affected by the pressure of high or low tide. Methane emissions from the seafloor can be just easily three times as much or as little, depending on the tide, according to a new study.
Published Light-induced Meissner effect
(via sciencedaily.com) Original source Researchers have developed a new experiment capable of monitoring the magnetic properties of superconductors at very fast speeds.
Published Scientists call for 'major initiative' to study whether geoengineering should be used on glaciers
(via sciencedaily.com) Original source Scientists have released a landmark report on glacial geoengineering -- an emerging field studying whether technology could halt the melting of glaciers and ice sheets as climate change progresses.
Published A breakthrough on the edge: One step closer to topological quantum computing
(via sciencedaily.com) Original source Researchers have achieved a significant breakthrough in quantum materials, potentially setting the stage for advancements in topological superconductivity and robust quantum computing.
Published The Gulf Stream is wind-powered and could weaken from climate change
(via sciencedaily.com) Original source New evidence of changes to the Gulf Stream during the last ice age could indicate additional sensitivity to future climatic changes, finds a new study.
Published Moving from the visible to the infrared: Developing high quality nanocrystals
(via sciencedaily.com) Original source Awarded the 2023 Nobel Prize in Chemistry, quantum dots have a wide variety of applications ranging from displays and LED lights to chemical reaction catalysis and bioimaging. These semiconductor nanocrystals are so small -- on the order of nanometers -- that their properties, such as color, are size dependent, and they start to exhibit quantum properties. This technology has been really well developed, but only in the visible spectrum, leaving untapped opportunities for technologies in both the ultraviolet and infrared regions of the electromagnetic spectrum.
Published Whale remains tracked to highlight sustainable disposal benefits
(via sciencedaily.com) Original source A new study highlights the sustainable, cultural and ecosystem benefits of offshore removal or decomposition of whale remains. The study tracked the remains of a humpback whale that was intercepted before washing up on the shoreline, then repositioned 30km offshore and fitted with a satellite tag that tracked its position as it drifted with the wind and currents for 6 days before falling to the seabed.
