Published Rivers and streams in the Andean Cordillera are hot spots for greenhouse gases emissions
(via sciencedaily.com) Researchers show that rivers in the Andean mountains contribute 35% and 72% of riverine emissions of carbon dioxide (CO2 ) and methane (CH4 ) in the Amazon basin, the world's largest river.
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 Evidence that Venus is volcanically active
(via sciencedaily.com) Venus appears to have volcanic activity, according to a new research paper that offers strong evidence to answer the lingering question about whether Earth's sister planet currently has eruptions and lava flows.
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 Remains of a modern glacier found near Mars' equator implies water ice possibly present at low latitudes on Mars even today
(via sciencedaily.com) Scientists revealed the discovery of a relict glacier near Mars' equator. Located in Eastern Noctis Labyrinthus at coordinates 7° 33' S, 93° 14' W, this finding is significant as it implies the presence of surface water ice on Mars in recent times, even near the equator. This discovery raises the possibility that ice may still exist at shallow depths in the area, which could have significant implications for future human exploration.
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 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 Scientists call for global push to eliminate space junk
(via sciencedaily.com) As almost 200 countries agree a legally-binding treaty to protect the High Seas, a collaboration of experts in ocean plastic pollution and satellite technology has urged world leaders to learn lessons from the management of the High Seas and act now to protect Earth's orbit.
