Published Electronic skin as flexible as crocodile skin
(via sciencedaily.com) A research team has developed a crocodile-skin-inspired omnidirectionally stretchable pressure sensor.
Published New approach to harvesting aerial humidity with organic crystals
(via sciencedaily.com) Researchers have reported a novel method of harvesting water from naturally occurring sources such as fog and dew.
Published Rsearchers examine combined effects of two combustion technologies on the emission of coal-fired boilers
(via sciencedaily.com) There is currently a large dependence on coal for power generation. As coal-fired plants cause environmental and health hazards, technologies such as swirl flow and air staging have been proposed to mitigate the pollutants in their emissions. However, it is unclear how effective these technologies are in reducing the environmental costs of these plants. Now, researchers have provided insights on this front in a new study, delineating their efficacies with experiments and simulations.
Published Review of world water resources
(via sciencedaily.com) A recent review study provides an overview of the planet's freshwater supplies and strategies for sustainably managing them.
Published Where did Earth's water come from? Not melted meteorites, according to scientists
(via sciencedaily.com) A new study brings scientists one step closer to answering the question of where Earth's water came from.
Published New model provides improved air-quality predictions in fire-prone areas
(via sciencedaily.com) Globally, wildfires are becoming more frequent and destructive, generating a significant amount of smoke that can be transported thousands of miles, driving the need for more accurate air pollution forecasts. Researchers have now developed a deep learning model that provides improved predictions of air quality in wildfire-prone areas and can differentiate between wildfires and non-wildfires.
Published Microneedle-based drug delivery technique for plants
(via sciencedaily.com) The agriculture industry is under pressure to adopt sustainable and precise agricultural practices that enable more efficient use of resources due to worsening environmental conditions resulting from climate change, an ever-expanding human population, limited resources, and a shortage of arable land. As a result, developing delivery systems that efficiently distribute micronutrients, pesticides, and antibiotics in crops is crucial to ensuring high productivity and high-quality produce while minimising resource waste. However, current and standard practices for agrochemical application in plants are inefficient. These practices cause significant detrimental environmental side effects, such as water and soil contamination, biodiversity loss and degraded ecosystems; and public health concerns, such as respiratory problems, chemical exposure and food contamination.
Published Tech could help BC farmers reach customers, mitigate climate change impacts
(via sciencedaily.com) Technology exists that the BC government could leverage to help small farmers connect directly with consumers and also mitigate climate change impacts, say new findings.
Published Climate change alters a human-raptor relationship
(via sciencedaily.com) Bald Eagles and dairy farmers exist in a mutually beneficial relationship in parts of northwestern Washington State. According to a new study, this 'win-win' relationship has been a more recent development, driven by the impact of climate change on eagles' traditional winter diet of salmon carcasses, as well as by increased eagle abundance following decades of conservation efforts.
Published Switching to hydrogen fuel could prolong the methane problem
(via sciencedaily.com) Hydrogen is often heralded as the clean fuel of the future, but new research suggests that leaky hydrogen infrastructure could end up increasing atmospheric methane levels, which would cause decades-long climate consequences.
Published Researchers find decaying biomass in Arctic rivers fuels more carbon export than previously thought
(via sciencedaily.com) A new study found that plants and small organisms in Arctic rivers could be responsible for more than half the particulate organic matter flowing to the Arctic Ocean. That's a significantly greater proportion than previously estimated, and it has implications for how much carbon gets sequestered in the ocean and how much moves into the atmosphere.
Published Minke whales are as small as a lunge-feeding baleen whale can be
(via sciencedaily.com) A new study of Antarctic minke whales reveals a minimum size limit for whales employing the highly efficient 'lunge-feeding' strategy that enabled the blue whale to become the largest animal on Earth.
Published Arctic climate modelling too conservative
(via sciencedaily.com) Climate models used by the UN's IPCC and others to project climate change are not accurately reflecting what the Arctic's future will be, experts say.
Published Remarkable squirting mussels captured on film
(via sciencedaily.com) Researchers have observed a highly unusual behavior in the endangered freshwater mussel, Unio crassus. The jets disturb the river surface and attract fish. Mussel larvae in the jets can then attach to the gills of the fish and complete their metamorphosis into adults.
Published Existential threats to the iconic Nile River Delta
(via sciencedaily.com) Decades of poor environmental and water management turned the Nile River Delta from a unique ecological habitat in the Sahara to one of the largest polluted areas on the planet, with tens of millions of people and migrating birds at risk of exposure to water-borne contaminants.
Published Assessing the potential risks of ocean-based climate intervention technologies on deep-sea ecosystems
(via sciencedaily.com) An international team of experts convened remotely as part of the Deep Ocean Stewardship Initiative's Climate Working Group to consider the deep-sea impacts of ocean-based climate intervention (OBCI). A research team has analyzed the proposed approaches to assess their potential impacts on deep-sea ecosystems and biodiversity. Their findings raise substantial concern on the potential impacts of these technologies on deep-sea ecosystems and call for the need for an integrated research effort to carefully assess the cost and benefits of each intervention.
Published Standard model of electroporation refuted
(via sciencedaily.com) Strong electric fields can be used to create pores in biomembranes. The method is known as electroporation. Inducing such defects in membranes in a targeted manner is an important technique in medicine and biotechnology, but also in the treatment of foodstuffs.
Published The world's atmospheric rivers now have an intensity ranking like hurricanes
(via sciencedaily.com) Atmospheric rivers, which are long, narrow bands of water vapor, are becoming more intense and frequent with climate change. A new study demonstrates that a recently developed scale for atmospheric river intensity (akin to the hurricane scale) can be used to rank atmospheric rivers and identify hotspots of the most intense atmospheric rivers not only along the U.S. West Coast but also worldwide.
Published Life in the smoke of underwater volcanoes
(via sciencedaily.com) Disconnected from the energy of the sun, the permanently ice-covered Arctic deep sea receives miniscule amounts of organic matter that sustains life. Bacteria which can harvest the energy released from submarine hydrothermal sources could thus have an advantage. Scientists found bacteria uniquely adapted to this geo-energy floating in deep-sea waters. They describe the role of these bacteria for biogeochemical cycling in the ocean.
Published How climate change threatens Asia's water tower
(via sciencedaily.com) Original source Tibet is known as the 'Water Tower of Asia,' providing water to about 2 billion people and supporting critical ecosystems in High Mountain Asia and the Tibetan Plateau, where many of the largest Asian river systems originate. This region is also one of the areas most vulnerable to the compounding effects of climate change and human activities. Researchers are identifying policy changes that need to happen now to prepare for the future impacts projected by climate models.
