Published Solar-powered device produces clean water and clean fuel at the same time
(via sciencedaily.com) Original source A floating, solar-powered device that can turn contaminated water or seawater into clean hydrogen fuel and purified water, anywhere in the world, has been developed by researchers.
Published quantum mechanics: Unlocking the secrets of spin with high-harmonic probes
(via sciencedaily.com) Original source Deep within every piece of magnetic material, electrons dance to the invisible tune of quantum mechanics. Their spins, akin to tiny atomic tops, dictate the magnetic behavior of the material they inhabit. This microscopic ballet is the cornerstone of magnetic phenomena, and it's these spins that a team of researchers has learned to control with remarkable precision, potentially redefining the future of electronics and data storage.
Published New work sheds light on inner working of cells
(via sciencedaily.com) Original source New research provides a deeper understanding of the way components within cells are interconnected. Through cellular visualization using SRS microscopy, researchers have addressed the challenge of attaining clear images of individual processes.
Published Scientists found hundreds of toxic chemicals in recycled plastics
(via sciencedaily.com) Original source When scientists examined pellets from recycled plastic collected in 13 countries they found hundreds of toxic chemicals, including pesticides and pharmaceuticals. Because of this, the scientists judge recycled plastics unfit for most purposes and a hinder in the attempts to create a circular economy.
Published Found at last: Bizarre, egg-laying mammal finally rediscovered after 60 years
(via sciencedaily.com) Original source A long-beaked echidna named after Sir David Attenborough and last seen by scientists in 1961 has been photographed for the first time in an Indonesian tropical forest. An international team of researchers worked with local communities to deploy over 80 camera traps to film the elusive animal. Besides rediscovering the echidna, the team uncovered a wealth of species completely new to science, including beetles, spiders, and a remarkable tree-dwelling shrimp.
Published Scientists caution against a reliance on mechanical devices to clear water bodies of plastic
(via sciencedaily.com) Original source An international group of scientists has called for the United Nations Treaty on Plastic Pollution to focus more on measures to reduce the production and consumption of plastics and the prevention of future plastic waste, rather than on the unselective removal of waste already in the water.
Published Chemists image basic blocks of synthetic polymers
(via sciencedaily.com) Original source Researchers have developed a new method to image polymerization catalysis reactions one monomer at a time.
Published New way to count microbes speeds research, cuts waste, could lead to new antibiotics
(via sciencedaily.com) Original source Researchers have developed a new way of counting microorganisms that works as much as 36 times faster than conventional methods, cuts plastic use more than 15-fold and substantially decreases the cost and carbon footprint of biomedical research. The technique could revolutionize the way microbiology experiments are conducted, allowing researchers to test potential new antibiotics in a fraction of the time.
Published Scientists use quantum biology, AI to sharpen genome editing tool
(via sciencedaily.com) Original source Scientists used their expertise in quantum biology, artificial intelligence and bioengineering to improve how CRISPR Cas9 genome editing tools work on organisms like microbes that can be modified to produce renewable fuels and chemicals.
Published Barnacle bends shape to fend off warm-water sea snails on the move
(via sciencedaily.com) Original source Some barnacles are 'morphing' to protect themselves from predatory warm-water sea snails, which are expanding into their territory due to climate change.
Published Plastics treaty must tackle problem at source
(via sciencedaily.com) Original source The new Global Plastics Treaty must tackle the problem at source, researchers say. They say the treaty must prioritize 'upstream' issues: cutting total production and consumption of plastics, phasing out hazardous chemicals and tackling fossil fuel subsidies.
Published Liquid metals shake up century-old chemical engineering processes
(via sciencedaily.com) Original source Liquid metals could be the long-awaited solution to 'greening' the chemical industry, according to researchers who tested a new technique they hope can replace energy-intensive chemical engineering processes harking back to the early 20th century.
Published Greenland's glacier retreat rate has doubled over past two decades
(via sciencedaily.com) Original source A new study documents how Greenland's peripheral glaciers have changed from 1890 to 2022. Using satellite images and a unique archive of historical aerial photos, researchers documented changes in the lengths of more than 1,000 of the country's glaciers over the past 130 years. Although glaciers in Greenland have experienced retreat throughout the last century, the rate of their retreat has rapidly accelerated over the last two decades.
Published Zooplankton in ocean and freshwater are rapidly escalating the global environmental threat of plastics
(via sciencedaily.com) Original source A collaborative research team has recently revealed that rotifers, a kind of microscopic zooplankton common in both fresh and ocean water around the world, are able to chew apart microplastics, breaking them down into even smaller, and potentially more dangerous, nanoplastics -- or particles smaller than one micron. Each rotifer can create between 348,000 -- 366,000 per day, leading to uncountable swarms of nanoparticles in our environment.
Published A different take on phosphorus: Bacteria use organic phosphorus and release methane in the process
(via sciencedaily.com) Original source Some bacteria are able to tap into unusual sources of nutrients in the surface water of the oceans. This enables them to increase their primary production and extract more carbon dioxide from the atmosphere. In doing so, however, they release the potent greenhouse gas methane.
Published The secret to longer lasting batteries might be in how soap works
(via sciencedaily.com) Original source Researchers show that one of the most promising substances for designing longer lasting lithium batteries form micelle-like structures like they do in soap.
Published Scaling up nano for sustainable manufacturing
(via sciencedaily.com) Original source A research team has developed a high-performance coating material that self-assembles from 2D nanosheets, and which could significantly extend the shelf life of electronics, energy storage devices, health & safety products, and more. The researchers are the first to successfully scale up nanomaterial synthesis into useful materials for manufacturing and commercial applications.
Published New dates for landslides reveal past Seattle fault earthquakes
(via sciencedaily.com) Original source New maps of more than 1,000 deep-seated landslides in the Puget Lowlands of Washington State provide evidence of the last major earthquake along the Seattle Fault about 1,100 years ago -- and may also hold traces of older earthquakes along the fault.
Published Maps reveal biochar's potential for mitigating climate change
(via sciencedaily.com) Original source Twelve countries have the technical ability to sequester over 20% of their current total greenhouse gas emissions by converting crop residues to biochar. Bhutan leads the way with the potential to sequester 68% of its emissions in the form of biochar, followed by India, at 53%.
Published Africa's dangerous air pollution levels are a global problem, says new research
(via sciencedaily.com) Original source A new report has brought to light the challenge of air pollution levels in Africa and why international action is needed to combat it.
