(via sciencedaily.com) Original source High levels of plastic pollution can kill the embryos of a wide range of ocean animals, new research shows.
Published Crucial connection for 'quantum internet' made for the first time
(via sciencedaily.com) Original source Researchers have produced, stored, and retrieved quantum information for the first time, a critical step in quantum networking.
Published Quantum precision: A new kind of resistor
(via sciencedaily.com) Original source Researchers have developed a method that can improve the performance of quantum resistance standards. It's based on a quantum phenomenon called Quantum Anomalous Hall effect.
Published Where have all the right whales gone?
(via sciencedaily.com) Original source Marine researchers have mapped the density of one of the most endangered large whale species worldwide, the North Atlantic right whale, using new data to help avoid right whales' harmful exposure to commercial fisheries and vessel strikes. The resulting maps, spanning 20 years of whale observations, are publicly available to inform risk assessments, estimations of whale harm/disturbance, marine spatial planning, and industry regulations to mitigate risk to right whales.
Published Oceanographers uncover the vital role of mixing down of oxygen in sustaining deep sea health
(via sciencedaily.com) Original source Oceanographers have shown for the first time the important role of the 'mixing down' of oxygen in maintaining healthy conditions in the deep waters.
Published Tropical coral-infecting parasites discovered in cold marine ecosystems
(via sciencedaily.com) Original source Parasites thought only to infect tropical coral reefs have been discovered in a large variety of creatures in cold marine ecosystems along the Northeast Pacific, according to new research.
Published Breakthrough promises secure quantum computing at home
(via sciencedaily.com) Original source The full power of next-generation quantum computing could soon be harnessed by millions of individuals and companies, thanks to a breakthrough guaranteeing security and privacy. This advance promises to unlock the transformative potential of cloud-based quantum computing.
Published Geobiology: New placozoan habitat discovered
(via sciencedaily.com) Original source Traces of DNA in the stomachs of predatory snails give a team og geobiologists new insights into the ecology of placozoans.
Published Quantum breakthrough when light makes materials magnetic
(via sciencedaily.com) Original source The potential of quantum technology is huge but is today largely limited to the extremely cold environments of laboratories. Now, researchers have succeeded in demonstrating for the very first time how laser light can induce quantum behavior at room temperature -- and make non-magnetic materials magnetic. The breakthrough is expected to pave the way for faster and more energy-efficient computers, information transfer and data storage.
Published 3D mouth of an ancient jawless fish suggests they were filter-feeders, not scavengers or hunters
(via sciencedaily.com) Original source Early jawless fish were likely to have used bony projections surrounding their mouths to modify the mouth's shape while they collected food. Experts have used CT scanning techniques to build up the first 3D pictures of these creatures, which are some of the earliest vertebrates (animals with backbones) in which the mouth is fossilized. Their aim was to answer questions about feeding in early vertebrates without jaws in the early Devonian epoch -- sometimes called the Age of Fishes -- around 400 million years ago.
Published New method of measuring qubits promises ease of scalability in a microscopic package
(via sciencedaily.com) Original source The path to quantum supremacy is made challenging by the issues associated with scaling up the number of qubits. One key problem is the way that qubits are measured. A research group introduces a new approach that tackles these challenges head-on using nanobolometers instead of traditional, bulky parametric amplifiers.
Published Cold-affinity algae species are gradually being replaced by warm-affinity ones off the coast of Biscay
(via sciencedaily.com) Original source A study has analyzed the impact of the rise in sea surface temperature on macroalgae communities over the last four decades. Points at various depths were investigated in a location off the coast of Biscay, and an increasing scarcity was observed in the number of cold-affinity structuring species, while small warm-affinity ones have proliferated. The researchers are warning that some ecological functions are in jeopardy as a result.
Published What's quieter than a fish? A school of them
(via sciencedaily.com) Original source Swimming in schools makes fish surprisingly stealthy underwater, with a group able to sound like a single fish. Engineers working with a high-tech simulation of schooling mackerel offer new insight into why fish swim in schools and promise for the design and operation of much quieter submarines and autonomous undersea vehicles.
Published Impact of climate change on marine life much bigger than previously known
(via sciencedaily.com) Original source Fish and invertebrate animals are far more affected by warmer and more acidic seawater than was previously known. The big gain of the new method is that more details become known about effects of climate change on species.
Published New technique lets scientists create resistance-free electron channels
(via sciencedaily.com) Original source A team has taken the first atomic-resolution images and demonstrated electrical control of a chiral interface state -- an exotic quantum phenomenon that could help researchers advance quantum computing and energy-efficient electronics.
Published Will the convergence of light and matter in Janus particles transcend performance limitations in the optical display industry?
(via sciencedaily.com) Original source Team successfully exerted electrical control over polaritons, hybridized light-matter particles, at room temperature.
Published eDNA methods give a real-time look at coral reef health
(via sciencedaily.com) Original source The study underscores the crucial role of microbes in maintaining coral reef health, akin to the human gut microbiome. Hurricanes and disease outbreaks affect coral reef water microbial communities, leading to changes that may support further reef decline. Microbial analysis enables prompt assessment of disturbances' impacts on coral reefs, facilitating timely interventions to support reef ecosystems. Environmental DNA (eDNA) analysis offers a noninvasive approach to study coral microbial communities and diagnose reef health.
Published Chemical reactions can scramble quantum information as well as black holes
(via sciencedaily.com) Original source A team of researchers has shown that molecules can be as formidable at scrambling quantum information as black holes by combining mathematical tools from black hole physics and chemical physics and testing their theory in chemical reactions.
Published What four decades of canned salmon reveal about marine food webs
(via sciencedaily.com) Original source Researchers have shown that levels of anisakid worms -- a common marine parasite -- rose in two salmon species in the Gulf of Alaska and Bristol Bay over a 42-year period. The team discovered this by studying salmon caught, killed and canned from 1979 to 2021. Since anisakid worms have a complex life cycle involving multiple types of hosts, the researchers interpret their rising numbers as a potential sign of ecosystem recovery, possibly driven by rising numbers of marine mammals thanks to the 1972 Marine Mammal Protection Act.
Published Shy sea anemones are more likely to survive heatwaves
(via sciencedaily.com) Original source A study shows that sea anemones that react more slowly to change can survive a heatwave better than individuals that change their behavior quickly.
