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 Habitat will dictate whether ground beetles win or lose against climate change
(via sciencedaily.com) The success of North American crops from corn to Christmas trees partly depends on a relatively invisible component of the food web -- ground beetles. Nearly 2,000 species of ground beetle live in North America. New research shows that some of these insects could thrive while others could decline as the climate changes. The team found that the response will largely depend on the species' traits and habitats and could have significant implications for conservation efforts.
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 ice will soon disappear from the Arctic during the summer months -- and it has happened before
(via sciencedaily.com) In a new study, an international team of researchers warn that the Arctic Sea ice may soon be a thing of the past in the summer months. This may have consequences for both the climate and ecosystems. Ten thousand years ago, the ice melted at temperatures similar to those we have today.
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 Human and ocean health impacts of ocean plastics
(via sciencedaily.com) Researchers from the fields of healthcare, ocean science, and social science have collaborated to quantify plastic's considerable risks to all life on Earth. The Minderoo-Monaco Commission on Plastics and Human Health report presents a comprehensive analysis showing plastics as a hazard at every stage of their life cycle.
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 Forest growing season in eastern U.S. has increased by a month
(via sciencedaily.com) The growing period of hardwood forests in eastern North America has increased by an average of one month over the past century as temperatures have steadily risen, a new study has found.
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 Douglas-fir in Klamath Mountains are in 'decline spiral'
(via sciencedaily.com) Increases in mortality among Douglas-fir in the Klamath Mountains are the result of multiple factors that have the iconic tree in a 'decline spiral' in parts of the region.
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.
Published Jellyfish size might influence their nutritional value
(via sciencedaily.com) Researchers confirmed what was already known: jellyfish eat bigger prey as they grow, which means they also occupy a higher position in the food web as they grow. They also found that some of the concentrations of 'healthy fats,' increase as jellyfish grow. These changes might be influenced by their diet, and as they feed on bigger prey with higher levels of fatty acids, the jellyfish accumulate more of these fatty acids.
Published Coffee plantations limit birds' diets
(via sciencedaily.com) A new study explores a record of birds' diets preserved in their feathers and radio tracking of their movements to find that birds eat far fewer invertebrates in coffee plantations than in forests, suggesting that the disturbance of their ecosystem significantly impacts the birds' dietary options.
Published Stalactites and stalagmites in the battery?
(via sciencedaily.com) They are considered the 'Holy Grail' of battery research: so-called 'solid-state batteries'. They no longer have a liquid core, as is the case with today's batteries, but consist of a solid material. This leads to several advantages: Among other things, these batteries are more difficult to ignite and can also be manufactured on a miniature scale. Scientists have now turned their attention to the life cycle of such batteries and targeted processes that reduce it. With their findings, more durable solid-state batteries could be realized in the future.
Published Noise harming ocean invertebrates and ecosystems
(via sciencedaily.com) Noise from human activities is harming ocean invertebrates and ecosystems, new research shows.
Published Mountain forests are being lost at an accelerating rate, putting biodiversity at risk
(via sciencedaily.com) More than 85% of the world's bird, mammal, and amphibian species live in mountains, particularly in forest habitats, but researchers report that these forests are disappearing at an accelerating rate. Globally, we have lost 78.1 million hectares (7.1%) of mountain forest since 2000 -- an area larger than the size of Texas. Much of the loss occurred in tropical biodiversity hotspots, putting increasing pressure on threatened species.
Published How can we tackle the biggest challenges? Ask a plant
(via sciencedaily.com) Without plants, we'd have no air to breathe or food to eat, yet plant science lingers in the shadowy wings while other fields take center stage. With the goal of shining the spotlight on plants, a new study presents the field's top 100 most pressing questions for research to address the greatest challenges facing humanity.
Published Fossil site is 'Rosetta Stone' for understanding early life
(via sciencedaily.com) Leading edge technology has uncovered secrets about a world-renowned fossil hoard that could offer vital clues about early life on Earth. Researchers who analyzed the 400 million-year-old cache, found in rural north-east Scotland, say their findings reveal better preservation of the fossils at a molecular level than was previously anticipated.
Published Study shines new light on ancient microbial dark matter
(via sciencedaily.com) An international research team produced the first large-scale analysis of more than 400 newly sequenced and existing Omnitrophota genomes, uncovering new details about their biology and behavior.
