Published Plastic cloud: New study analyzes airborne microplastics in clouds
(via sciencedaily.com) Original source Plastic waste that accumulates on land eventually ends up in the ocean as microplastics. However, it is now speculated that microplastics are also present in the atmosphere, contained in clouds. In a new study, researchers analyzed cloud water samples from high-altitude mountains in Japan to ascertain the amount of microplastics in them. They also shed light on how these airborne particles influence cloud formation and their negative impact on the climate.
Published Novel bacterial proteins from seafloor shine light on climate and astrobiology
(via sciencedaily.com) Original source Researchers have unveiled a remarkable discovery: the identification of novel bacterial proteins that play a vital role in the formation and stability of methane clathrates, which trap gigatons of greenhouse gas beneath the seafloor. These newfound proteins not only suppress methane clathrate growth as effectively as toxic chemicals used in drilling but also prove to be eco-friendly and scalable. This innovative breakthrough not only promises to enhance environmental safety in natural gas transportation but also sheds light on the potential for similar biomolecules to support life beyond Earth.

Published How organic solar cells could become significantly more efficient
(via sciencedaily.com) Original source The sun sends enormous amounts of energy to the earth. Nevertheless, some of it is lost in solar cells. This is an obstacle in the use of organic solar cells, especially for those viable in innovative applications. A key factor in increasing their performance: Improved transport of the solar energy stored within the material. Now a research group has shown that certain organic dyes can help build virtual highways for the energy.
Published Genetically engineering associations between plants and nitrogen-fixing microbes could lessen dependence on synthetic fertilizer
(via sciencedaily.com) Original source Nitrogen is an essential nutrient for plant growth, but the overuse of synthetic nitrogen fertilizers in agriculture is not sustainable. A team of bacteriologists and plant scientists discuss the possibility of using genetic engineering to facilitate mutualistic relationships between plants and nitrogen-fixing microbes called 'diazotrophs.' These engineered associations would help crops acquire nitrogen from the air by mimicking the mutualisms between legumes and nitrogen-fixing bacteria.
Published Double trouble: Infamous 'eagle killer' bacterium produces not one, but two toxins
(via sciencedaily.com) Original source The cyanobacterium Aetokthonos hydrillicola produces not just one, but two highly potent toxins. Scientists describe the second toxin, which had remained elusive until now. Even in low concentrations, it can destroy cells and is similar to substances currently used in cancer treatment. Two years ago, the same team established that the first toxin from the cyanobacterium is the cause of a mysterious disease among bald eagles in the USA.
Published New research reveals extreme heat likely to wipe out humans and mammals in the distant future
(via sciencedaily.com) Original source A new study shows unprecedented heat is likely to lead to the next mass extinction, akin to when the dinosaurs died out, eliminating nearly all mammals in some 250 million years time.
Published Waterfleas hold key to cleaner environment and better human health
(via sciencedaily.com) Original source Tiny waterfleas could play a pivotal role in removing persistent chemical pollutants from wastewater -- making it safe to use in factories, farms and homes, a new study reveals.

Published Drug discovery on an unprecedented scale
(via sciencedaily.com) Boosting virtual screening with machine learning allowed for a 10-fold time reduction in the processing of 1.56 billion drug-like molecules. Researchers teamed up with industry and supercomputers to carry out one of the world's largest virtual drug screens.
Published Ocean acidification makes ecologically important seaweed species fragile
(via sciencedaily.com) Original source Ocean acidification will likely almost triple by the end of the century -- a drastic environmental change that could impact important marine species like fleshy seaweeds, algae that grow vertically and promote biodiversity in more than a third of the world's coastline. To get a better idea of how seaweeds might fare in a rapidly acidifying ocean, a team of marine scientists subjected a common fleshy seaweed species to the acidification levels expected by the end of the century. They report that increased acidification impacted the seaweed's chemical balance, made both its structure and its tissues weaker, and reduced its overall chances of survival.
Published There is much to improve in identifying all the chemicals around us
(via sciencedaily.com) What chemicals are we exposed to on a daily basis? That is the central question of 'non-targeted analysis' or NTA, an emerging field of analytical science that aims to identify all chemicals around us. A daunting task, because how can you be sure to detect everything if you don't know exactly what you're looking for?
Published Re-wetting is key for boosting CO2 storage in southern US peatlands
(via sciencedaily.com) Original source Maintaining a water level between 20 and 30 centimeters below the local water table will boost southern peatlands' carbon storage and reduce the amount of greenhouse gases they release back into the atmosphere during dry periods by up to 90%, a new study finds. Applying this guideline on 100,000 acres of restored or partially restored peatlands across the Southeast could reduce U.S. carbon losses by 2% to 3% of our total national goal.
Published Nanoparticles made from plant viruses could be farmers' new ally in pest control
(via sciencedaily.com) Engineers have devised a new solution to control a major agricultural menace, root-damaging nematodes. Using plant viruses, the researchers created nanoparticles that can deliver pesticide molecules to previously inaccessible depths in the soil. This 'precision farming' approach could potentially minimize environmental toxicity and cut costs for farmers.
Published Chicago's West Side is air pollution hotspot
(via sciencedaily.com) Original source The western edge of Chicago -- including the North and South Lawndale, East Garfield Park, Archer Heights and Brighton Park neighborhoods -- experiences up to 32% higher concentrations of nitrogen dioxide (NO2) air pollution compared to the rest of the city.
Published How climate warming could disrupt a deep-rooted relationship
(via sciencedaily.com) Trees depend on fungi for their well-being. As climate change and global warming cause higher temperatures and amplified drought, little is known about how these important fungi will respond. To investigate this issue, a research team conducted a climate change experiment where they exposed boreal and temperate tree species to warming and drought treatments to better understand how fungi and their tree hosts respond to environmental changes. Their findings revealed that the combined effects of warming and water stress will likely result in major disturbances of ectomycorrhizal networks and may harm forest resilience and function.
