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.

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.

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.

Turning old maps into 3D digital models of lost neighborhoods      (via sciencedaily.com)     Original source 

Imagine strapping on a virtual reality headset and 'walking' through a long-gone neighborhood in your city -- seeing the streets and buildings as they appeared decades ago. That's a very real possibility now that researchers have developed a method to create 3D digital models of historic neighborhoods using machine learning and historic Sanborn Fire Insurance maps.

NeuWS camera answers 'holy grail problem' in optical imaging      (via sciencedaily.com)     Original source 

Engineers have demonstrated full-motion video camera technology that can 'see' through light-scattering media. The research could potentially be used in cameras that peer through fog, smoke, driving rain, murky water and parts of the body that hide tumors and other lesions.

Octopus sleep is surprisingly similar to humans and contains a wake-like stage      (via sciencedaily.com)     Original source 

Researchers have closely examined the brain activity and skin patterning in octopuses (Octopus laqueus) during active sleep and discovered that it closely resembles neural activity and skin patterning behavior seen when awake.

Life after death: Astronomers find a planet that shouldn't exist      (via sciencedaily.com)     Original source 

The star would have inflated up to 1.5 times the planet's orbital distance -- engulfing the planet in the process -- before shrinking to its current size at only one-tenth of that distance.

Starlight and the first black holes: researchers detect the host galaxies of quasars in the early universe      (via sciencedaily.com)     Original source 

For the first time, the James Webb Space Telescope has revealed starlight from two massive galaxies hosting actively growing black holes -- quasars -- seen less than a billion years after the Big Bang.

Magnetic bacteria point the way      (via sciencedaily.com)     Original source 

Magnetotactic bacteria, which can align with the Earth's magnetic field, have been discovered in a new location. Previously observed on land and in shallow water, analysis of a hydrothermal vent has proven that they can also survive deep under the ocean. The bacteria were able to exist in an environment that was not ideal for their typical needs. Magnetotactic bacteria are of interest not only for the role they play in Earth's ecosystem, but also in the search for extraterrestrial life. Evidence of their existence can remain in rocks for billions of years. Their magnetic inclinations can also provide a record of how magnetic poles have shifted over time. This new discovery brings hope to researchers that the magnetic bacteria might be found in yet more unexpected locations, on Earth and perhaps even on Mars or beyond.

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.

Researchers make a quantum computing leap with a magnetic twist      (via sciencedaily.com)     Original source 

Scientists and engineers have announced a significant advancement in developing fault-tolerant qubits for quantum computing. In a pair of articles, they report that, in experiments with flakes of semiconductor materials -- each only a single layer of atoms thick -- they detected signatures of 'fractional quantum anomalous Hall' (FQAH) states. The team's discoveries mark a first and promising step in constructing a type of fault-tolerant qubit because FQAH states can host anyons -- strange 'quasiparticles' that have only a fraction of an electron's charge. Some types of anyons can be used to make what are called 'topologically protected' qubits, which are stable against any small, local disturbances.

Bigger bottles keep champagne bubbly for decades      (via sciencedaily.com)     Original source 

Tiny bubbles bursting in a drinker's face and the bite of carbonation are all part of the experience when sipping champagne and sparkling wines. But how long can these drinks be stored in sealed bottles before they go flat? According to researchers, the answer depends on the container's size. They estimate a 40-year shelf-life for 750-milliliter (25-ounce) bottles, and 82 and 132 years for 1.5-liter (50-ounce) and 3-liter (101-ounce) bottles, respectively.

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.

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.
