Published Soil tainted by air pollution expels carbon
(via sciencedaily.com) New research suggests nitrogen released by gas-powered machines causes dry soil to let go of carbon and release it back into the atmosphere, where it can contribute to climate change.
Published 1. 5-degree goal not plausible: Social change more important than physical tipping points
(via sciencedaily.com) Limiting global warming to 1.5 degrees Celsius is currently not plausible, as is shown in a new, central study. Climate policy, protests, and the Ukraine crisis: the participating researchers systematically assessed to what extent social changes are already underway -- while also analyzing certain physical processes frequently discussed as tipping points. Their conclusion: social change is essential to meeting the temperature goals set in Paris. But what has been achieved to date is insufficient.
Published China's stricter clean heating policies may have saved thousands of lives
(via sciencedaily.com) China's stricter clean heating policies have improved air quality in northern China, particularly in Beijing and surrounding cities -- potentially reducing 23,000 premature deaths due to air pollution in 2021 than in 2015, a new study reveals.
Published Over 4% of summer mortality in European cities is attributable to urban heat islands
(via sciencedaily.com) Original source Over four percent of deaths in cities during the summer months are due to urban heat islands, and one third of these deaths could be prevented by reaching a tree cover of 30%, according to a modelling study. The study results, obtained with data from 93 European cities, highlight the substantial benefits of planting more trees in cities to attenuate the impact of climate change.
Published Silver nanoparticles show promise in fighting antibiotic-resistant bacteria
(via sciencedaily.com) A new study found that small amounts of silver nanoparticles combined with a low dose of a common antibiotic inhibited the growth of resistant bacteria.
Published Thin, lightweight layer provides radiation barrier for perovskites in space, protection from elements on Earth
(via sciencedaily.com) An ultrathin protective coating proves sufficient to protect a perovskite solar cell from the harmful effects of space and harden it against environmental factors on Earth, according to newly published research.
Published Deer carry SARS-CoV-2 variants that are extinct in humans
(via sciencedaily.com) Researchers have found white-tailed deer -- the most abundant large mammal in North America -- are harboring SARS-CoV-2 variants that were once widely circulated, but no longer found in humans.
Published Diversity of viroids and viroid-like agents
(via sciencedaily.com) A team of researchers has developed a computational pipeline to identify and better understand viroids and viroid-like covalently closed circular RNAs (cccRNAs, also referred to as, simply, circular RNAs).
Published Warmer climate may drive fungi to be more dangerous to our health
(via sciencedaily.com) A new study finds that raised temperatures cause a pathogenic fungus known as Cryptococcus deneoformans to turn its adaptive responses into overdrive. Heat increases its number of genetic changes, some of which might presumably lead to higher heat resistance, and others perhaps toward greater disease-causing potential.
Published Far-off storms fuel sneaker waves along Pacific Northwest coast, new research suggests
(via sciencedaily.com) Sneaker waves are likely fueled by a specific type of wave condition generated by far-off storms and paired with just the right conditions closer to shore, a new study has found.
Published Researchers take a step toward novel quantum simulators
(via sciencedaily.com) If scaled up successfully, the team's new system could help answer questions about certain kinds of superconductors and other unusual states of matter.
Published With rapidly increasing heat and drought, can plants adapt?
(via sciencedaily.com) As deserts expanded their range over the past 5-7 million years, many plants invaded the new biome and rapidly diversified, producing amazing adaptations to drought and heat. Can plants continue to adapt to increasing aridity caused by climate change? A new study that addressed the origins of desert adaptation concluded that one group of desert plants, rock daisies, came preadapted to aridity, likely helping them survive desert conditions. Not all plants may be so lucky.
Published 'Snapshots' of translation could help us investigate cellular proteins
(via sciencedaily.com) Original source Nascent polypeptide chains or polypeptidyl-tRNAs (pep-tRNAs) occur transiently during protein synthesis. The potential to study these intermediates and better understand their role in processes like gene regulation has been greatly enhanced by the development of a process termed PETEOS -- short for peptidyl-tRNA enrichment using organic extraction and silica adsorption. This method allows for the large-scale harvesting, processing, and identification of pep-tRNA polypeptide moieties.
Published Aquatic organisms respond to flooding and drought disturbance in different ways
(via sciencedaily.com) Populations of various species of aquatic insects and other invertebrates respond to flooding and waterway drying due to drought in different ways that can be anticipated, according to a new study that employed a novel method to assess the stability of stream ecosystems.
Published Deer browsing is just one of many factors shaping North American forests
(via sciencedaily.com) In a new study, a research team discovered evidence that browsing by white-tailed deer had relatively little long-term impact on two tree species in a northern forest.
Published New live bacterial product for stubborn superbug improves quality of life
(via sciencedaily.com) The stubborn superbug Clostridium difficile, or C. diff, may have met its match. A esearcher is reporting the first well-controlled study to demonstrate the effectiveness of a new medicine for patients with the debilitating recurrent infection and disease.
Published Biorefinery uses microbial fuel cell to upcycle resistant plant waste
(via sciencedaily.com) Researchers have developed a sustainable, inexpensive two-step process that can upcycle organic carbon waste -- including lignin, a difficult-to-breakdown material that gives plants their structure. By processing waste through a microbe-driven biorefinery, the researchers turned lignin into carbon sources that could be used in high-value, plant-derived pharmaceuticals and antioxidant nutraceuticals as well as carbon-based nanoparticles for drug or chemical delivery.
Published Scientists release newly accurate map of all the matter in the universe
(via sciencedaily.com) A group of scientists have released one of the most precise measurements ever made of how matter is distributed across the universe today.
Published Understanding plants can boost wildland-fire modeling in uncertain future
(via sciencedaily.com) A new conceptual framework for incorporating the way plants use carbon and water, or plant dynamics, into fine-scale computer models of wildland fire provides a critical first step toward improved global fire forecasting.
Published 'Ghostly mirrors' for high-power lasers
(via sciencedaily.com) Original source Laser-driven 'mirrors' capable of reflecting or manipulating light have been produced.
