Published Shark fear: Just when you thought it was safe to get back in the water...
(via sciencedaily.com) Original source It's one of the most famous taglines in film history, immortalizing sharks as ruthless predators. But beyond the horror generated by Spielberg's Jaws series, a persistent fear of sharks remains, with consequences that extend into reality.
Published New water treatment method can generate green energy
(via sciencedaily.com) Original source Researchers have designed micromotors that move around on their own to purify wastewater. The process creates ammonia, which can serve as a green energy source. Now, an AI method will be used to tune the motors to achieve the best possible results.
Published Study sheds light on how Earth cycles fossil-carbon
(via sciencedaily.com) Original source Researches used rhenium as a proxy for fossil carbon in order to quantify the rate at which Earth naturally releases carbon dioxide into the atmosphere and found that high rates of carbon breakdown persist across the different geographical profiles of a river basin.
Published Research provides crucial insights into moss growth under elevated CO2 levels that may benefit climate change models
(via sciencedaily.com) Original source Approximately 12,000 species of mosses exist and cover close to four million square miles of earth, equivalent to the size of Canada, and are ecologically and evolutionarily important. Mosses play an essential role in rainwater retention, decreasing plant pathogens and increasing carbon sequestration in soil, thus improving the overall soil health. Mosses also protect long-term carbon storage systems, such as bogs and permafrost.
Published New tool models viability of closed-loop geothermal systems
(via sciencedaily.com) Original source Researchers have used computer models of closed-loop geothermal systems to determine if they would be economically viable sources of renewable energy. They found that the cost of drilling would need to decrease significantly to hit cost targets.
Published A tale of two proteins: Fundamental research could make growing better crops like clockwork
(via sciencedaily.com) Original source Rhomboid-like protein 10, or RBL10, is thought to be an enzyme that degrades other proteins in the chloroplast membrane, but its function is largely unknown. Researchers are studying how RBL10 affects photosynthetic membrane lipid metabolism, an essential process in photosynthesis.
Published Earth's surface water dives deep, transforming core's outer layer
(via sciencedaily.com) Original source A new study has revealed that water from the Earth's surface can penetrate deep into the planet, altering the composition of the outermost region of the metallic liquid core and creating a distinct, thin layer. Illustration of silica crystals coming out from the liquid metal of the Earth's outer core due to a water-induced chemical reaction.
Published Ammonia fuel offers great benefits but demands careful action
(via sciencedaily.com) Original source Researchers have identified the potential environmental risks of using ammonia as a zero-carbon fuel in order to develop an engineering roadmap to a sustainable ammonia economy.
Published New discovery on how green algae count cell divisions illuminates key step needed for the evolution of multicellular life
(via sciencedaily.com) Original source An international research team has made an unexpected discovery of a biased counting mechanism used by the single-celled green alga Chlamydomonas to control cell division.
Published Aerosols: When scents influence our climate
(via sciencedaily.com) Original source Tiny particles that form from molecules in the air play an important role for climate change. But until now, the have been poorly understood. Scientists have now analyzed how these particles form.
Published Forming ice: There's a fungal protein for that
(via sciencedaily.com) Original source New research explores how proteins produced by a common fungus trigger ice nucleation at warm temperatures. The study holds potential implications for improving our understanding of how life affects precipitation and climate.
Published New study indicates C4 crops less sensitive to ozone pollution than C3 crops
(via sciencedaily.com) Original source Researchers have studied the effects of elevated O3 on five C3 crops (chickpea, rice, snap bean, soybean, wheat) and four C4 crops (sorghum, maize, Miscanthus × giganteus, switchgrass). Their findings indicate that C4 crops are much more tolerant of high O3 concentrations than C3 crops.
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 Yucatán's underwater caves host diverse microbial communities
(via sciencedaily.com) Original source With help from an experienced underwater cave-diving team, researchers have constructed the most complete map to date of the microbial communities living in the submerged labyrinths beneath Mexico's Yucatán Peninsula. Researchers found the cave system's microbiome is distinct from the nearby sea, and microbial communities vary between cave systems forming distinct 'neighborhoods.'
Published How mega-floods can be predicted
(via sciencedaily.com) Original source Extreme flood events are extraordinary outliers that were not considered possible on the basis of local data. However, if one considers the entire European continent, these local surprises are no longer surprising at all. If data from other regions with similar hydrological conditions is taken into account, the extent of these 'mega-floods' suddenly becomes predictable.
Published Yeast cells can produce drugs for treatment of psychotic disorders
(via sciencedaily.com) Original source An international team of researchers has demonstrated that genetically engineered yeast cells can produce the natural plant product alstonine, which has shown positive effects in treating schizophrenia.
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 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 fifth of European Red List flora and fauna species may be at risk of extinction
(via sciencedaily.com) Original source A new analysis of 14,669 threatened species of plants and animals found in Europe reveals that about one fifth face the risk of extinction, and that agricultural land-use change poses a significant threat to these species.
