Published The climate crisis and biodiversity crisis can't be approached as two separate things



Anthropogenic climate change has, together with the intensive use and destruction of natural ecosystems through agriculture, fishing and industry, sparked an unprecedented loss of biodiversity that continues to worsen. In this regard, the climate crisis and biodiversity crisis are often viewed as two separate catastrophes. An international team of researchers calls for adopting a new perspective.
Published African penguins: Climate refugees from a distant past?



Imagine the view from the western coastline of southern Africa during the Last Glacial Maximum (LGM) over twenty thousand years ago: in the distance you would see at least fifteen large islands -- the largest 300 square kilometers in area -- swarming with hundreds of millions of marine birds and penguin colonies.
Published Scientists identify 2022 sea urchin killer



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 X-ray analysis sheds new light on prehistoric predator's last meal



We now know more about the diet of a prehistoric creature that grew up to two and a half meters long and lived in Australian waters during the time of the dinosaurs, thanks to the power of x-rays. Researchers used micro-CT scans to peer inside the fossilized stomach remains of a small marine reptile -- a plesiosaur nicknamed 'Eric' after a song from the comedy group Monty Python -- to determine what the creature ate in the lead up to its death.
Published Even as temperatures rise, this hydrogel material keeps absorbing moisture



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



A tiny biobattery that could still work after 100 years has been developed.
Published Chemists propose ultrathin material for doubling solar cell efficiency



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 Swimming secrets of prehistoric reptiles unlocked by new study



The diverse swimming techniques of the ancient reptiles that ruled the Mesozoic seas have been revealed.
Published Scientists discover pristine deep-sea coral reefs in the Galápagos Marine Reserve



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



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 Less ice, fewer calling seals



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 A solar hydrogen system that co-generates heat and oxygen



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 Learning about what happens to ecology, evolution, and biodiversity in times of mass extinction



Studying mass extinction events from the past can build our understanding of how ecosystems and the communities of organisms within them respond. Researchers are looking to the Late Devonian mass extinction which happened around 370 million years ago to better understand how communities of organisms respond in times of great upheaval.
Published Microwaves advance solar-cell production and recycling



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



Scientists have developed an extremely small and fast nano-excitonic transistor.
Published Gentle method allows for eco-friendly recycling of solar cells



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



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 Temperature is stronger than light and flow as driver of oxygen in US rivers



The amount of dissolved oxygen in a river is a matter of life or death for the plants and animals living within it, but this oxygen concentration varies drastically from one river to another, depending on their unique temperature, light and flow. To better understand which factor has the greatest impact on the concentration of dissolved oxygen, researchers used a deep learning model to analyze data from hundreds of rivers across the United States.
Published Cities will need more resilient electricity networks to cope with extreme weather



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 New textile unravels warmth-trapping secrets of polar bear fur



Engineers have invented a fabric that concludes the 80-year quest to make a synthetic textile modeled on polar bear fur. The results are already being developed into commercially available products.
