Supercomputer used to simulate winds that cause clear air turbulence      (via sciencedaily.com) 

Using Japan's most powerful supercomputer, researchers reproduced cases of clear air turbulence around Tokyo. They simulated the fine vortices responsible for this dangerous phenomenon. The usefulness of the simulation in predicting turbulence was confirmed by comparing simulation data with data from aircraft recordings. This research should improve the forecasting of turbulence.

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.

Marine fossils are a reliable benchmark for degrading and collapsing ecosystems      (via sciencedaily.com)     Original source 

Humans began altering environments long before records were kept of the things that lived in them, making it difficult for scientists to determine what healthy ecosystems should look like. Researchers show the recent fossil record preserves a reliable snapshot of marine environments as they existed before humans.

Scientists discover 36-million-year geological cycle that drives biodiversity      (via sciencedaily.com)     Original source 

Movement in the Earth's tectonic plates indirectly triggers bursts of biodiversity in 36 million-year cycles by forcing sea levels to rise and fall, new research has shown.

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.

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.

Discovery of 500-million-year-old fossil reveals astonishing secrets of tunicate origins      (via sciencedaily.com)     Original source 

Researchers describe a 500 million-year-old tunicate fossil species. The study suggests that the modern tunicate body plan was already established soon after the Cambrian Explosion.

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.

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.

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.

New study sheds light on the evolution of animals      (via sciencedaily.com)     Original source 

Scientists have been mystified as to why animals are missing in much of the fossil record. Researchers have now developed a new method to determine if animals really were absent during certain geological eras, or if they were present but too fragile to be preserved.

Humans' ancestors survived the asteroid impact that killed the dinosaurs      (via sciencedaily.com)     Original source 

A Cretaceous origin for placental mammals, the group that includes humans, dogs and bats, has been revealed by in-depth analysis of the fossil record, showing they co-existed with dinosaurs for a short time before the dinosaurs went extinct.

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.

50-million-year-old katydid fossil reveals muscles, digestive tract, glands and a testicle      (via sciencedaily.com)     Original source 

50 million years ago in what is now northwestern Colorado, a katydid died, sank to the bottom of a lake and was quickly buried in fine sediments, where it remained until its compressed fossil was recovered in recent years. When researchers examined the fossil under a microscope, they saw that not only had many of the insect's hard structures been preserved in the compressed shale, so had several internal organs and tissues, which are not normally fossilized.

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.
