Published Viscose manufactured solely from recycled materials
(via sciencedaily.com) Original source At present, viscose textiles are made of biomass from the forest, and there is no such thing as fully recycled viscose. Researchers have now succeeded in making new viscose -- from worn-out cotton sheets.
Published The world's most prolific CO2-fixing enzyme is slowly getting better
(via sciencedaily.com) Original source New research has found that rubisco -- the enzyme that fuels all life on Earth -- is not stuck in an evolutionary rut after all. The largest analysis of rubisco ever has found that it is improving all the time -- just very, very slowly. These insights could potentially open up new routes to strengthen food security.
Published Marine algae implants could boost crop yields
(via sciencedaily.com) Original source Scientists have discovered the gene that enables marine algae to make a unique type of chlorophyll. They successfully implanted this gene in a land plant, paving the way for better crop yields on less land.
Published Global warming is affecting bats' hibernation
(via sciencedaily.com) Original source Global change is altering the physiology of the hibernation and behavior of bats, according to a study carried out over a twenty year period. Given the milder winters we are having, bats are accumulating less fat reserves in autumn, they shorten their hibernation periods and they leave their winter shelter sooner. These changes could alter the migration pattern of bats and the phenology of their seasonal displacements.
Published Breakthrough research enables high-density hydrogen storage for future energy systems
(via sciencedaily.com) Original source A research team has reported a groundbreaking development in efficient hydrogen storage.
Published Nanodevices can produce energy from evaporating tap or seawater
(via sciencedaily.com) Original source Researchers have discovered that nanoscale devices harnessing the hydroelectric effect can harvest electricity from the evaporation of fluids with higher ion concentrations than purified water, revealing a vast untapped energy potential.
Published Finding new physics in debris from colliding neutron stars
(via sciencedaily.com) Original source Neutron star mergers are a treasure trove for new physics signals, with implications for determining the true nature of dark matter, according to physicists.
Published Astronomers spot oldest 'dead' galaxy yet observed
(via sciencedaily.com) Original source A galaxy that suddenly stopped forming new stars more than 13 billion years ago has been observed by astronomers. Using the James Webb Space Telescope, astronomers have spotted a 'dead' galaxy when the universe was just 700 million years old, the oldest such galaxy ever observed.
Published Herbivores, displaced by ocean warming, threaten subtropical seagrass meadows
(via sciencedaily.com) Original source The findings suggest that subtropical seagrasses are less resilient to heavy grazing from marine herbivores, in part because they receive less sunlight relative to their tropical counterparts. As tropical herbivores move into subtropical waters, overgrazing may prevent subtropical seagrass meadows from persisting in these environments.
Published Discovery tests theory on cooling of white dwarf stars
(via sciencedaily.com) Original source Open any astronomy textbook to the section on white dwarf stars and you'll likely learn that they are 'dead stars' that continuously cool down over time. Astronomers are challenging this theory after discovering a population of white dwarf stars that stopped cooling for more than eight billion years.
Published Sinking land increases risk for thousands of coastal residents by 2050
(via sciencedaily.com) Original source A new study provides a new comprehensive look at the potential for flooding in a combined 32 cities along the Atlantic, Pacific, and Gulf coasts. It predicts as many as 500,000 people will be affected by flooding alongside 1 in 35 privately owned properties within the next three decades, and it highlights the racial and socioeconomic demographics of those potentially affected.
Published Key advance toward removing common herbicide from groundwater
(via sciencedaily.com) Original source Chemists are closing in on a new tool for tackling the global problem of weedkiller-tainted groundwater.
Published Research explores the cooling effects of 'scuba-diving' in lizards
(via sciencedaily.com) Original source Anoles are the scuba-diving champions of the lizard world, able to stay underwater for more than 16 minutes. For animals whose body temperature depends on the environment, time spent in a cool running stream can have some tradeoffs, according to new research.
Published Short-term exposure to high levels of air pollution kills 1 million globally every year
(via sciencedaily.com) Original source Every year, more than one million deaths globally occur because of exposure to short-term (hours to days) fine particulate matter (PM2.5) in air pollution, according to a new report, with Eastern Asia reporting more than 50% of deaths attributable to short-term PM2.5 globally.
Published Harmful 'forever chemicals' removed from water with new electrocatalysis method
(via sciencedaily.com) Original source Scientists have developed new electrochemical approaches to clean up pollution from 'forever chemicals' found in clothing, food packaging, firefighting foams, and a wide array of other products. A new study describes nanocatalysts developed to remediate per- and polyfluoroalkyl substances, known as PFAS.
Published Smart optimization paves the way for improved silicon solar cell performance
(via sciencedaily.com) Original source Bayesian optimization (BO) can help determine the optimal deposition conditions for high-performance passivation films in solar cells. However, simple implementations tend to suggest excessively thick films or infeasible deposition conditions. Recently, researchers from Japan developed a novel constrained BO scheme that combines several prediction models to restrict suggested deposition conditions to realistic values. Their strategy could help minimize trial and error and improve material performance in various fields.
Published Space tourism? Cosmic radiation exposure
(via sciencedaily.com) Original source Space weather experts are urging regulators and space tourism innovators to work together to protect their passengers and crews from the risks of space weather radiation exposure.
Published Groundbreaking survey reveals secrets of planet birth around dozens of stars
(via sciencedaily.com) Original source A team of astronomers has shed new light on the fascinating and complex process of planet formation. The research brings together observations of more than 80 young stars that might have planets forming around them, providing astronomers with a wealth of data and unique insights into how planets arise in different regions of our galaxy.
Published What makes black holes grow and new stars form? Machine learning helps solve the mystery
(via sciencedaily.com) Original source It takes more than a galaxy merger to make a black hole grow and new stars form: machine learning shows cold gas is needed too to initiate rapid growth -- new research finds.
Published Microalgae with unusual cell biology
(via sciencedaily.com) Original source A globally distributed single-celled organism that occurs in harmful algal blooms has been found to exhibit an unusual organisation of photosynthesis. Researchers have taken a closer look at the unusual cell biology of the species Prorocentrum cordatum from the group of dinoflagellates. The results of their study could help to better understand the role of the species in the environment and the increased occurrence of algal blooms at higher water temperatures.
