Published Researchers find decaying biomass in Arctic rivers fuels more carbon export than previously thought
(via sciencedaily.com) A new study found that plants and small organisms in Arctic rivers could be responsible for more than half the particulate organic matter flowing to the Arctic Ocean. That's a significantly greater proportion than previously estimated, and it has implications for how much carbon gets sequestered in the ocean and how much moves into the atmosphere.
Published Magnetism fosters unusual electronic order in quantum material
(via sciencedaily.com) Physicists have published an array of experimental evidence showing that the ordered magnetic arrangement of electrons in crystals of iron-germanium plays an integral role in bringing about an ordered electronic arrangement called a charge density wave that the team discovered in the material last year.
Published Study shows how biodiversity of coral reefs around the world changes with depth
(via sciencedaily.com) Dramatic differences between shallow and mesophotic reefs stress the importance of studying--and conserving--these vital ecosystems along their entire depth gradient.
Published Minke whales are as small as a lunge-feeding baleen whale can be
(via sciencedaily.com) A new study of Antarctic minke whales reveals a minimum size limit for whales employing the highly efficient 'lunge-feeding' strategy that enabled the blue whale to become the largest animal on Earth.
Published Experiment unlocks bizarre properties of strange metals
(via sciencedaily.com) Physicists are learning more about the bizarre behavior of 'strange metals,' which operate outside the normal rules of electricity.
Published Assessing the potential risks of ocean-based climate intervention technologies on deep-sea ecosystems
(via sciencedaily.com) An international team of experts convened remotely as part of the Deep Ocean Stewardship Initiative's Climate Working Group to consider the deep-sea impacts of ocean-based climate intervention (OBCI). A research team has analyzed the proposed approaches to assess their potential impacts on deep-sea ecosystems and biodiversity. Their findings raise substantial concern on the potential impacts of these technologies on deep-sea ecosystems and call for the need for an integrated research effort to carefully assess the cost and benefits of each intervention.
Published Sea temperatures control the distributions of European marine fish
(via sciencedaily.com) An analysis extending from southern Portugal to northern Norway highlights the importance of temperature in determining where fish species are found.
Published Ringing an electronic wave: Elusive massive phason observed in a charge density wave
(via sciencedaily.com) Researchers have detected the existence of a charge density wave of electrons that acquires mass as it interacts with the background lattice ions of the material over long distances.
Published In the world's smallest ball game, scientists throw and catch single atoms using light
(via sciencedaily.com) Researchers show that individual atoms can be caught and thrown using light. This is the first time an atom has been released from a trap -- or thrown -- and then caught by another trap. This technology could be used in quantum computing applications.
Published Hitting nuclei with light may create fluid primordial matter
(via sciencedaily.com) A new analysis supports the idea that photons colliding with heavy ions create a fluid of 'strongly interacting' particles. The results indicate that photon-heavy ion collisions can create a strongly interacting fluid that responds to the initial collision geometry and that these collisions can form a quark-gluon plasma. These findings will help guide future experiments at the planned Electron-Ion Collider.
Published Unprecedented increase in ocean plastic since 2005 revealed by four decades of global analysis
(via sciencedaily.com) A global dataset of ocean plastic pollution between 1979 and 2019 reveals a rapid and unprecedented increase in ocean plastics since 2005, according to a new study.
Published Researchers take a step towards turning interactions that normally ruin quantum information into a way of protecting it
(via sciencedaily.com) A new method for predicting the behavior of quantum devices provides a crucial tool for real-world applications of quantum technology.
Published Major North American oil source yields clues to one of earth's deadliest mass extinctions
(via sciencedaily.com) Geologists studying the Bakken Shale Formation discovered a critical kill mechanism behind a series of extinctions some 350 million years ago.
Published Paleontologists flip the script on anemone fossils
(via sciencedaily.com) Billions of sea anemones adorn the bottom of the Earth's oceans -- yet they are among the rarest of fossils because their squishy bodies lack easily fossilized hard parts. Now a team of paleontologists has discovered that countless sea anemone fossils have been hiding in plain sight for nearly 50 years. It turns out that fossils long-interpreted as jellyfish were anemones. To do so, a team of scientists has simply turned the ancient animals upside down.
Published Does current shellfish anti-predator gear curb 'crunching' rays?
(via sciencedaily.com) It's not just humans who enjoy eating shellfish, so do marine rays. They like to 'crunch' on clams, which can sometimes take a big bite out of clammers' profits. Using aerial and underwater videos, researchers assessed the ability of the whitespotted eagle ray to interact with clams housed within a variety anti-predator materials. Whitespotted eagle rays have strong jaws, plate-like teeth and nimble pectoral fins, which make them formidable and highly maneuverable predators of clams.
Published Graphene quantum dots show promise as novel magnetic field sensors
(via sciencedaily.com) Trapped electrons traveling in circular loops at extreme speeds inside graphene quantum dots are highly sensitive to external magnetic fields and could be used as novel magnetic field sensors with unique capabilities, according to a new study.
Published Mineral particles and their role in oxygenating the Earth's atmosphere
(via sciencedaily.com) Mineral particles played a key role in raising oxygen levels in the Earth's atmosphere billions of years ago, with major implications for the way intelligent life later evolved, according to new research.
Published Two-dimensional quantum freeze
(via sciencedaily.com) Researchers have succeeded in simultaneously cooling the motion of a tiny glass sphere in two dimensions to the quantum ground-state. This represents a crucial step towards a 3D ground-state cooling of a massive object and opens up new opportunities for the design of ultra-sensitive sensors.
Published An innovative twist on quantum bits: Tubular nanomaterial of carbon makes ideal home for spinning quantum bits
(via sciencedaily.com) Scientists develop method for chemically modifying nanoscale tubes of carbon atoms, so they can host spinning electrons to serve as stable quantum bits in quantum technologies.
Published Toothed whales catch food in the deep using vocal fry
(via sciencedaily.com) Toothed whales, such as dolphins, killer whales and sperm whales communicate and catch food exclusively with sound. Now researchers have for the first time found they evolved a new sound source in their nose that is functionally the same as the human larynx.
