Published Major storage capacity in water-based batteries
(via sciencedaily.com) Original source Chemical engineers have discovered a 1,000% difference in the storage capacity of metal-free, water-based battery electrodes.
Published Warming Arctic draws marine predators northwards
(via sciencedaily.com) Original source Marine predators have expanded their ranges into the Arctic waters over the last twenty years, driven by climate change and associated increases in productivity.
Published Ocean warming intensifies viral outbreaks within corals
(via sciencedaily.com) Original source A groundbreaking three-year study in the South Pacific has found evidence that ocean warming can trigger outbreaks of 'dinoflagellate-infecting RNA viruses' that attack symbiotic algae inside corals. Coral reef viruses have gained greater attention since being implicated in 2021 as a possible cause of stony coral tissue loss disease that has decimated Florida and Caribbean reefs for almost a decade.
Published Scientists discover hidden crab diversity among coral reefs
(via sciencedaily.com) The Indo-West Pacific is the largest marine ecosystem on Earth, but scientists who study its diversity have to contend with a problem so well-known it was remarked upon by Charles Darwin: related species in the IWP have similar appearances, making it difficult to assess just how many there are. A new study reveals that nearly identical crab species have one consistently distinguishing feature, which only evolves when their ranges overlap.
Published Earth prefers to serve life in XXS and XXL sizes
(via sciencedaily.com) Life comes in all shapes in sizes, but some sizes are more popular than others, new research has found. A survey of body sizes of all Earth's living organisms has uncovered an unexpected pattern. Contrary to what current theories can explain, our planet's biomass -- the material that makes up all living organisms -- is concentrated in organisms at either end of the size spectrum.
Published Juvenile black rockfish affected by marine heat wave but not always for the worse, research shows
(via sciencedaily.com) Larvae produced by black rockfish, a linchpin of the West Coast commercial fishing industry for the past eight decades, fared better during two recent years of unusually high ocean temperatures than had been feared, new research finds.
Published Detecting coral biodiversity in seawater samples
(via sciencedaily.com) Researchers have developed a method to measure coral biodiversity through extracting the environmental DNA (or eDNA) from a liter of surface seawater collected from above a reef. The method has been confirmed to work through observations made by scientific divers in the same areas of ocean. This has paved the way for large-scale comprehensive surveys of reef-building coral to take place and removes the reliance of direct observations made through scientific scuba diving or snorkeling.
Published How whale shark rhodopsin evolved to see, in the deep blue sea
(via sciencedaily.com) A group of researchers discovered that the rhodopsin -- a protein in the eye that detects light -- of whale sharks has changed to efficiently detect blue light, which penetrates deep-sea water easily. The amino acid substitutions -- one of which is counterintuitively associated with congenital stationary night blindness in humans -- aid in detecting the low levels of light in the deep-sea. Although these changes make the whale shark rhodopsin less thermally stable the deep-sea temperature, allows their rhodopsin to keep working. This suggests that the unique adaptation evolved to function in the low-light low-temperature environment where whale sharks live.
Published Revolutionary battery technology to boost EV range 10-fold or more
(via sciencedaily.com) A team develops layering-charged, polymer-based stable high-capacity anode material.
Published Conserving wildlife can help mitigate climate change
(via sciencedaily.com) Solving the climate crisis and biodiversity crisis are not separate issues. Animals remove billions of tons of carbon dioxide each year. Restoring species will help limit global warming, new science reveals.
Published Turtles and crocodiles with unique characteristics are more likely to go extinct
(via sciencedaily.com) New study demonstrates that the most endangered turtles and crocodile species are those that have evolved unique life strategies. Many of the most threatened species carry out important ecosystem functions that other species depend on. Habitat loss was identified as the key overall threat to turtles and crocodiles, followed by climate change and global trade. Unique species faced additional pressure from local consumption, diseases, and pollution.
Published Some coastal salt marshes are keeping up with sea level rise -- for now
(via sciencedaily.com) The world's salty, tidal marshes are hotspots of carbon storage and productivity, building up sediments and plant material to stay above sea level. However, as sea level rises at an increasing rate, scientists debate whether it's possible for wetlands to win the race. New research reveals how salt marshes along the U.S. East Coast have responded to accelerating sea level rise by building elevation more quickly to keep pace with the sea over the last century.
Published Climate change threatens global fisheries
(via sciencedaily.com) The diet quality of fish across large parts of the world's oceans could decline by up to 10 per cent as climate change impacts an integral part of marine food chains, a major study has found.
Published Phytoplankton blooms offer insight into impacts of climate change
(via sciencedaily.com) The first study into the biological response of the upper ocean in the wake of South Pacific cyclones could help predict the impact of warming ocean temperatures, researchers believe.
Published Sea otters killed by unusual parasite strain
(via sciencedaily.com) An unusually severe form of toxoplasmosis killed four sea otters and could pose a threat to other marine wildlife and humans, finds a new study.
Published New invention: The oxygen-ion battery
(via sciencedaily.com) An oxygen-ion-battery has been invented, based on ceramic materials. If it degrades, it can be regenerated, therefore it potentially has an extremely long lifespan. Also, it does not require any rare elements and it is incombustible. For large energy storage systems, this could be an optimal solution.
Published Batteries: Passivation layer mystery solved
(via sciencedaily.com) In our daily lives, lithium-ion batteries have become indispensable. They function only because of a passivation layer that forms during their initial cycle. As researchers found out via simulations, this solid electrolyte interphase develops not directly at the electrode but aggregates in the solution. Their findings allow the optimization of the performance and lifetime of future batteries.
Published High-energy-density, long life-cycle rechargeable lithium metal batteries
(via sciencedaily.com) Research shows promise for developing high-energy-density rechargeable lithium-metal batteries and addressing the electrochemical oxidation instability of ether-based electrolytes.
Published Biodiversity amid climate change
(via sciencedaily.com) Fewer parasites in U.S. waters might be seen by many as a good thing, but a biologist says the trend signals potential danger for fish and other wildlife.
Published In hot water: Ocean warming impacts growth, metabolic rate and gene activity of newly hatched clownfish
(via sciencedaily.com) Future ocean warming and marine heatwaves could impact the growth and development of clownfish during their earliest life stages, suggests a new study.
