Published Immediate carbon cuts, common marine heatwave terminology urged
(via sciencedaily.com) Original source Oceanographers provide a reality check on the limitations of carbon dioxide removal and a warning that marine heatwaves need clear definitions so communities can adapt.
Published Scientists identify 2022 sea urchin killer
(via sciencedaily.com) Original source A team of researchers has identified a single-celled organism called a ciliate as the cause of a massive die-off event to a marine animal vital to coral reef health.
Published A once-stable glacier in Greenland is now rapidly disappearing
(via sciencedaily.com) Original source As climate change causes ocean temperatures to rise, one of Greenland's previously most stable glaciers is now retreating at an unprecedented rate, according to a new study.
Published Even as temperatures rise, this hydrogel material keeps absorbing moisture
(via sciencedaily.com) Original source Engineers find the hydrogel polyethylene glycol (PEG) doubles its water absorption as temperatures climb from 25 to 50 C, and could be useful for passive cooling or water harvesting in warm climates.
Published Tiny biobattery with 100-year shelf life runs on bacteria
(via sciencedaily.com) Original source A tiny biobattery that could still work after 100 years has been developed.
Published Chemists propose ultrathin material for doubling solar cell efficiency
(via sciencedaily.com) Original source Researchers are studying radical new ways to improve solar power and provide more options for the industry to explore. Chemists are proposing to make solar cells using not silicon, but an abundantly available natural material called molybdenum disulfide. Using a creative combination of photoelectrochemical and spectroscopic techniques, the researchers conducted a series of experiments showing that extremely thin films of molybdenum disulfide display unprecedented charge carrier properties that could someday drastically improve solar technologies.
Published Scientists discover pristine deep-sea coral reefs in the Galápagos Marine Reserve
(via sciencedaily.com) Original source Scientists have discovered extensive, ancient deep-sea coral reefs within the Galápagos Marine Reserve (GMR) -- the first of their kind ever to be documented inside the marine protected area (MPA) since it was established in 1998. The first reef observed was found at 400-600m (1,310-1,970 feet) depth at the summit of a previously unmapped seamount in the central part of the archipelago and supports a breathtaking mix of deep marine life.
Published Coastal species persist on high seas on floating plastic debris
(via sciencedaily.com) Original source The high seas have been colonized by a surprising number of coastal marine invertebrate species, which can now survive and reproduce in the open ocean, contributing strongly to the floating community composition. Researchers found coastal species, representing diverse taxonomic groups and life history traits, in the eastern North Pacific Subtropical Gyre on over 70 percent of the plastic debris they examined. Further, the debris carried more coastal species than open ocean species.
Published Environmental toxin PCB found in deep sea trench
(via sciencedaily.com) Original source Researchers on a deep-sea expedition have found PCB in sediment samples from the more than 8,000-meter-deep Atacama Trench in the Pacific Ocean.
Published Less ice, fewer calling seals
(via sciencedaily.com) Original source For several years, a team of researchers used underwater microphones to listen for seals at the edge of the Antarctic. Their initial findings indicate that sea-ice retreat has had significant effects on the animals' behavior: when the ice disappears, areas normally full of vocalizations become very quiet.
Published New approach estimates long-term coastal cliff loss
(via sciencedaily.com) Original source A new method for estimating cliff loss over thousands of years in Del Mar, California, may help reveal some of the long-term drivers of coastal cliff loss in the state.
Published A solar hydrogen system that co-generates heat and oxygen
(via sciencedaily.com) Original source Researchers have built a pilot-scale solar reactor that produces usable heat and oxygen, in addition to generating hydrogen with unprecedented efficiency for its size.
Published Microwaves advance solar-cell production and recycling
(via sciencedaily.com) Original source New technology advances solar-cell production and recycling. New microwave technology will improve the manufacture of solar cells and make them easier to recycle.
Published Processing data at the speed of light
(via sciencedaily.com) Original source Scientists have developed an extremely small and fast nano-excitonic transistor.
Published Gentle method allows for eco-friendly recycling of solar cells
(via sciencedaily.com) Original source By using a new method, precious metals can be efficiently recovered from thin-film solar cells. The method is also more environmentally friendly than previous methods of recycling and paves the way for more flexible and highly efficient solar cells.
Published Chemists redesign biological PHAs, 'dream' biodegradable plastics
(via sciencedaily.com) Original source They've been called 'dream' plastics: polyhydroxyalkanoates, or PHAs. Already the basis of a fledgling industry, they're a class of polymers naturally created by living microorganisms, or synthetically produced from biorenewable feedstocks. They're biodegradable in the ambient environment, including oceans and soil.
Published Predictive power of climate models may be masked by volcanoes
(via sciencedaily.com) Original source Simulated volcanic eruptions may be blowing up our ability to predict near-term climate, according to a new study.
Published Study re-evaluates hazards and climate impacts of massive underwater volcanic eruptions
(via sciencedaily.com) Original source Material left on the seafloor by bronze-age underwater volcanic eruptions is helping researchers better understand the size, hazards and climate impact of their parent eruptions, according to new research.
Published Cities will need more resilient electricity networks to cope with extreme weather
(via sciencedaily.com) Original source Dense urban areas amplify the effects of higher temperatures, due to the phenomenon of heat islands in cities. This makes cities more vulnerable to extreme climate events. Large investments in the electricity network will be necessary to cool us down during heatwaves and keep us warm during cold snaps, according to a new study.
Published Warm liquid spewing from Oregon seafloor comes from Cascadia fault, could offer clues to earthquake hazards
(via sciencedaily.com) Original source Oceanographers discovered warm, chemically distinct liquid shooting up from the seafloor about 50 miles off Newport. They named the unique underwater spring 'Pythia's Oasis.' Observations suggest the spring is sourced from water 2.5 miles beneath the seafloor at the plate boundary, regulating stress on the offshore subduction zone fault.
