Published An earthquake changed the course of the Ganges: Could it happen again?
(via sciencedaily.com) Original source A major earthquake 2,500 years ago caused one of the largest rivers on Earth to abruptly change course, according to a new study. The previously undocumented quake rerouted the main channel of the Ganges River in what is now densely populated Bangladesh, which remains vulnerable to big quakes.
Published Wear it, then recycle: Designers make dissolvable textiles from gelatin
(via sciencedaily.com) Original source Researchers hope their DIY machine will help designers around the world experiment with making their own, sustainable fashion and other textiles from a range of natural ingredients -- maybe even the chitin in crab shells or agar-agar from algae.
Published Improving soil health yields unexpected benefits for farmers
(via sciencedaily.com) Original source While farmer surveys suggest that carbon prices are still too low relative to the paperwork these programs demand, a new study finds that money alone does not explain either farmers' doubts about carbon markets or their interest in regenerative agriculture. Instead, many farmers view improving soil health as a way to improve their quality of life by reducing their dependence on agrochemical companies' products and advice.
Published The yuck factor counteracts sustainable laundry habits
(via sciencedaily.com) Original source Most people today would lean towards environmentally friendly life choices, but not at the expense of being clean. When it comes to our washing habits, the fear of being perceived as dirty often wins out over the desire to act in an environmentally friendly way. And the more inclined we are to feel disgusted, the more we wash our clothes. This is shown by a unique study that examines the driving forces behind our laundering behaviours and provides new tools for how people's environmental impact can be reduced.
Published Scientists unravel drivers of the global zinc cycle in our oceans, with implications for a changing climate
(via sciencedaily.com) Original source The understanding of the global zinc cycle in our oceans has important implications in the context of warming oceans. A warmer climate increases erosion, leading to more dust in the atmosphere and consequently more dust being deposited into the oceans. More dust means more scavenging of zinc particles, leading to less zinc being available to sustain phytoplankton and other marine life, thereby diminishing the oceans' ability to absorb carbon.
Published Video analysis of Iceland 2010 eruption could improve volcanic ash forecasts for aviation safety
(via sciencedaily.com) Original source Video footage of Iceland's 2010 Eyjafjallaj kull eruption is providing researchers with rare, up-close observations of volcanic ash clouds -- information that could help better forecast how far explosive eruptions disperse their hazardous ash particles.
Published Public more confident connecting increasing heat, wildfires with climate change than other extreme weather events, study finds
(via sciencedaily.com) Original source Researchers found that U.S. adults are fairly confident in linking wildfires and heat to climate change, but less confident when it comes to other extreme weather events like hurricanes, flooding or tornadoes.
Published Ancient ocean slowdown warns of future climate chaos
(via sciencedaily.com) Original source When it comes to the ocean's response to global warming, we're not in entirely uncharted waters. A new study shows that episodes of extreme heat in Earth's past caused the exchange of waters from the surface to the deep ocean to decline.
Published Quantum data assimilation: A quantum leap in weather prediction
(via sciencedaily.com) Original source Data assimilation is an important mathematical discipline in earth sciences, particularly in numerical weather prediction (NWP). However, conventional data assimilation methods require significant computational resources. To address this, researchers developed a novel method to solve data assimilation on quantum computers, significantly reducing the computation time. The findings of the study have the potential to advance NWP systems and will inspire practical applications of quantum computers for advancing data assimilation.
Published Dolphins with elevated mercury levels in Florida and Georgia
(via sciencedaily.com) Original source Scientists found elevated mercury levels in dolphins in the U.S. Southeast. The highest levels were found in dolphins in Florida's St. Joseph and Choctawhatchee Bays. Researchers study dolphins because they are considered a sentinel species for oceans and human health. Like us, they are high up in the food chain, live long lives, and share certain physiological traits. Some of their diet is most vulnerable to mercury pollution and is also eaten by people.
Published Western agricultural communities need water conservation strategies to adapt to future shortages
(via sciencedaily.com) Original source The Western U.S. is heavily reliant on mountain snowpacks and their gradual melt for water storage and supply, and climate change is expected to upend the reliability of this natural process. Many agricultural communities in this part of the country are examining ways to adapt to a future with less water, and new research shows that a focus on supplementing water supply by expanding reservoir capacity won't be enough to avert future water crises.
Published Researchers use 3D visualization to predict, prevent hurricane damage
(via sciencedaily.com) Original source The researchers say 3D visualization of hurricanes and storm surges allows them to understand how flooding will impact coastal communities by allowing them to vividly see how each building and road might be impacted by a given flood.
Published Upstream and downstream: River study highlights cross-country inequities
(via sciencedaily.com) Original source New research highlights inequities between downstream and upstream countries that share the same watershed. The study outlines how international agreements can better address shared resource problems and call for greater collaboration and coordination between these international neighbors.
Published Study estimates that between 1980 and 2020, 135 million premature deaths could be linked to fine particulate matter pollution
(via sciencedaily.com) Original source A study has revealed that fine particulate matter from 1980 to 2020 was associated with approximately 135 million premature deaths globally.
Published Earth and space share the same turbulence
(via sciencedaily.com) Original source Researchers have discovered that the turbulence found in the thermosphere -- known as the gateway to space -- and turbulence in the troposphere, here closer to sea level, follow the same physical laws despite having drastically different atmospheric compositions and dynamics.
Published Scientists 'read' the messages in chemical clues left by coral reef inhabitants
(via sciencedaily.com) Original source What species live in this coral reef, and are they healthy? Chemical clues emitted by marine organisms might hold that information. But in underwater environments, invisible compounds create a complex 'soup' that is hard for scientists to decipher. Now, researchers have demonstrated a way to extract and identify these indicator compounds in seawater. They found metabolites previously undetected on reefs, including three that may represent different reef organisms.
Published Climate crisis puts Australia's ski industry on slippery slope, but not all hope is lost
(via sciencedaily.com) Original source Australia's ski industry is at risk of major disruptions and shorter seasons if the current level of climate pollution continues, according to new modelling.
