Published A better understanding of turbulence
(via sciencedaily.com) Experiments at a unique wind tunnel show that laws formulated more than 80 years ago and their extensions only incompletely explain turbulent flows.
Published Unused renewable energy an option for powering NFT trade
(via sciencedaily.com) Original source Unused solar, wind, and hydroelectric power in the U.S. could support the exponential growth of transactions involving non-fungible tokens (NFTs), researchers have found.
Published Organic electronics: Sustainability during the entire lifecycle
(via sciencedaily.com) Original source Organic electronics can make a decisive contribution to decarbonization and, at the same time, help to cut the consumption of rare and valuable raw materials. To do so, it is not only necessary to further develop manufacturing processes, but also to devise technical solutions for recycling as early on as the laboratory phase. Materials scientists are now promoting this circular strategy.
Published Why there are no kangaroos in Bali (and no tigers in Australia)
(via sciencedaily.com) Original source Researchers are using a new model to clarify why millions of years ago more animal species from Asia made the leap to the Australian continent than vice versa. The climate in which the species evolved played an important role.
Published Public support hydrogen and biofuels to decarbonize global shipping
(via sciencedaily.com) Original source New research into public attitudes towards alternative shipping fuels shows public backing for biofuel and hydrogen. The study also found that nuclear was preferred to the heavy fuel oil (HFO) currently used in the global shipping industry, although both were perceived negatively. Ammonia had the least public support.
Published Giant stone artefacts found on rare Ice Age site in Kent, UK
(via sciencedaily.com) Original source Researchers have discovered some of the largest early prehistoric stone tools in Britain.
Published Fossils reveal how ancient birds molted their feathers -- which could help explain why ancestors of modern birds survived when all the other dinosaurs died
(via sciencedaily.com) Original source Birds are the only group of dinosaurs that survived the asteroid-induced mass extinction 66 million years ago. But not all the birds alive at the time made it. Why the ancestors of modern birds lived while so many of their relatives died has been a mystery that paleontologists have been trying to solve for decades. Two new studies point to one possible factor: the differences between how modern birds and their ancient cousins molt their feathers.
Published Apex predator of the Cambrian likely sought soft over crunchy prey
(via sciencedaily.com) Original source Biomechanical studies on the arachnid-like front 'legs' of an extinct apex predator show that the 2-foot (60-centimeter) marine animal Anomalocaris canadensis was likely much weaker than once assumed. One of the largest animals to live during the Cambrian, it was probably agile and fast, darting after soft prey in the open water rather than pursuing hard-shelled creatures on the ocean floor.
Published Scientists propose new strategy for modern sails to help shipping sector meet its carbon reduction goals
(via sciencedaily.com) Original source Researchers have identified a strategy that can offset the random and unpredictable nature of weather conditions that threaten carbon emission reduction efforts in the shipping sector.
Published How urea may have been the gateway to life
(via sciencedaily.com) Original source Urea reacts extremely quickly under the conditions that existed when our planet was newly formed. This new insight furthers our understanding of how life on Earth might have begun.
Published Newly discovered Jurassic fossils in Texas
(via sciencedaily.com) Original source Scientists have filled a major gap in the state's fossil record -- describing the first known Jurassic vertebrate fossils in Texas. The weathered bone fragments are from the limbs and backbone of a plesiosaur, an extinct marine reptile.
Published Wind farm noise exposure doesn't wake people up from their slumber more than road traffic noise
(via sciencedaily.com) Original source Short exposure to wind farm and road traffic noise triggers a small increase in people waking from their slumber that can fragment their sleep patterns, according to new research. But importantly, the new study also shows that wind farm noise isn't more disruptive to sleep than road traffic, which was a little more disruptive at the loudest audio level but not at more common levels. Sleep researchers have studied the impact of exposure to wind farm noise during sleep in three new scientific publications to better understand its impact.
Published Megalodon was no cold-blooded killer
(via sciencedaily.com) Original source How the megalodon, a shark that went extinct 3.6 million years ago, stayed warm was a matter of speculation among scientists. Using an analysis of tooth fossils from the megalodon and other sharks of the same period, a study suggests the animal was able to maintain a body temperature well above the temperature of the water in which it lived. The finding could help explain why the megalodon went extinct during the Pliocene Epoch.
Published City buildings could blow air taxi future off course
(via sciencedaily.com) Original source Air taxis may be coming to our cities in the near future, but a new study warns regulations will need to address dangerous wind gusts around city buildings and other urban infrastructure.
Published 'We're all Asgardians': New clues about the origin of complex life
(via sciencedaily.com) Original source According to a new study, eukaryotes -- complex life forms with nuclei in their cells, including all the world's plants, animals, insects and fungi -- trace their roots to a common Asgard archaean ancestor. That means eukaryotes are, in the parlance of evolutionary biologists, a 'well-nested clade' within Asgard archaea, similar to how birds are one of several groups within a larger group called dinosaurs, sharing a common ancestor.
Published Perovskite solar cells set new record for power conversion efficiency
(via sciencedaily.com) Original source Perovskite solar cells have attained now attained the extremely high efficiency rate of 24.35% with an active area of 1 cm2. This ground-breaking achievement in maximizing power generation from next-generation renewable energy sources will be crucial to securing the world's energy future.
Published Scientists unearth 20 million years of 'hot spot' magmatism under Cocos plate
(via sciencedaily.com) Original source A team of scientists has observed past episodic intraplate magmatism and corroborated the existence of a partial melt channel at the base of the Cocos Plate. Situated 60 kilometers beneath the Pacific Ocean floor, the magma channel covers more than 100,000 square kilometers, and originated from the Galápagos Plume more than 20 million years ago, supplying melt for multiple magmatic events -- and persisting today.
Published Face of Anglo-Saxon teen VIP revealed with new evidence about her life
(via sciencedaily.com) Original source The face of a 16-year-old woman buried near Cambridge (UK) in the 7th century with an incredibly rare gold and garnet cross (the 'Trumpington Cross') has been reconstructed following analysis of her skull. The striking image is going on public display for the first time on 21st June, with new scientific evidence showing that she moved to England from Central Europe as a young girl, leading to an intriguing change in her diet.
Published Clean, sustainable fuels made 'from thin air' and plastic waste
(via sciencedaily.com) Original source Researchers have demonstrated how carbon dioxide can be captured from industrial processes -- or even directly from the air -- and transformed into clean, sustainable fuels using just the energy from the Sun.
Published These long-necked reptiles were decapitated by their predators, fossil evidence confirms
(via sciencedaily.com) Original source In the age of dinosaurs, many marine reptiles had extremely long necks compared to reptiles today. While it was clearly a successful evolutionary strategy, paleontologists have long suspected that their long-necked bodies made them vulnerable to predators. Now, after almost 200 years of continued research, direct fossil evidence confirms this scenario for the first time in the most graphic way imaginable.
