Published Urban street networks, building density shape severity of floods
(via sciencedaily.com) Original source The design of streets and layout of buildings have an impact on a city's resilience in the face of increasingly severe floods brought on by climate change. Researchers look at buildings and other urban structures as physicists consider elements in complex material systems. With this insight, the researchers have developed a new approach to urban flood modelling and found their results helpful in analyzing city-to-city variations in flood risk globally.
Published Searching old stem cells that stay young forever
(via sciencedaily.com) Original source The sea anemone Nematostella vectensis is potentially immortal. Using molecular genetic methods, developmental biologists have now identified possible candidates for multipotent stem cells in the sea anemone for the first time. These stem cells are regulated by evolutionary highly conserved genes.
Published Preservation of organic carbon in the ocean floor
(via sciencedaily.com) Original source The preservation of organic carbon in marine sediments has long been a key question remaining unclear in understanding the long-term carbon cycling on Earth. Recently, scientists have gained new insights into the dynamic cycling of iron-bound organic carbon in subseafloor sediments.
Published New twist on synthesis technique promises sustainable manufacturing
(via sciencedaily.com) Original source Researchers developed a new method known as flash-within-flash Joule heating (FWF) that could transform the synthesis of high-quality solid-state materials, offering a cleaner, faster and more sustainable manufacturing process.
Published Nitrogen interventions as a key to better health and robust ecosystems
(via sciencedaily.com) Original source An international research team combined multidisciplinary methods to evaluate how nitrogen interventions could improve air quality and reduce nitrogen deposition. Their study found that interventions, such as improving fuel combustion conditions, increasing agricultural nitrogen use efficiency, and reducing food loss and waste, could significantly lower premature deaths attributed to air pollution, crop losses, and ecosystems risks.
Published Scottish and Irish rocks confirmed as rare record of 'snowball Earth'
(via sciencedaily.com) Original source The study found that the Port Askaig Formation, composed of layers of rock up to 1.1 km thick, was likely laid down between 662 to 720 million years ago during the Sturtian glaciation -- the first of two global freezes thought to have triggered the development of complex, multicellular life.
Published Rethinking the dodo
(via sciencedaily.com) Original source Researchers are setting out to challenge our misconceptions about the Dodo, one of the most well-known but poorly understood species of bird. Researchers have undertaken the most comprehensive review of the taxonomy of the Dodo and its closest relative, the Rodriguez Island Solitaire.
Published Exploring options for the sustainable management of phosphorus
(via sciencedaily.com) Original source A new study assessed the feasibility of recovering phosphorus from municipal wastewater as an alternative sustainable source of this non-renewable mineral.
Published Researchers discover smarter way to recycle polyurethane
(via sciencedaily.com) Original source Researchers have found a better method to recycle polyurethane foam from items like mattresses: They are not only able to break down PUR and separate the two main components -- they can do it in one go. This is great news for the budding industry that aims to chemically recover the original components of the material -- making their products cheaper and better.
Published Why isn't Colorado's snowpack ending up in the Colorado River? New research suggests the problem might be the lack of spring rainfall
(via sciencedaily.com) Original source The Colorado River and its tributaries provide water for hydropower, irrigation and drinking water in seven U.S. states and Mexico. But since 2000, water managers have struggled to predict how much water will come from the snowpack. The problem lies with the lack of rainfall in the spring, according to new research.
Published New research shows unprecedented atmospheric changes during May's geomagnetic superstorm
(via sciencedaily.com) Original source On May 11, a gorgeous aurora surprised stargazers across the southern United States. That same weekend, a tractor guided by GPS missed its mark. What do the visibility of the northern lights have in common with compromised farming equipment in the Midwest? A uniquely powerful geomagnetic storm, according to new research.
Published Blind cavefish have extraordinary taste buds
(via sciencedaily.com) Original source A biologist studies blind cavefish, a species of fish that dwell in cave ponds in Mexico. He looked at the timeline for when the cavefish develop additional taste buds on the head and chin, finding the taste bud expansion starts at five months and continues into adulthood.
Published U.S. capable of achieving seafood independence
(via sciencedaily.com) Original source If the U.S. became seafood independent, or meet its entire seafood needs through its own production, it could offer opportunities for improving dietary outcomes as well as individual and national food security, particularly against disruptions in global supply chains. Through analyzing 50 years of regional and national consumption and production data, from 1970-2021, researchers found that the U.S. could achieve seafood independence, although 'achieving greater seafood independence would require shifts in consumer behavior, investments in infrastructure and continual adaptation in the face of climate change.'
Published As human activities expand in Antarctica, scientists identify crucial conservation sites
(via sciencedaily.com) Original source Establishing Key Biodiversity Areas in the Southern Ocean will be vital for safeguarding the ecosystem from the impact of human activities, researchers say.
Published Blood pressure levels impacted by chronic occupational noise exposure
(via sciencedaily.com) Original source A new study found in adult power loom weavers, chronic noise exposure not only increased their blood pressure overall, but also each year of exposure increased their odds of having high blood pressure by 10%.
Published Intelligent soft robotic clothing for automatic thermal adaptation in extreme heat
(via sciencedaily.com) Original source As global warming intensifies, people increasingly suffer from extreme heat. For those working in a high-temperature environment indoors or outdoors, keeping thermally comfortable becomes particularly crucial. A team has now developed thermally-insulated and breathable soft robotic clothing that can automatically adapt to changing ambient temperatures, thereby helping to ensure worker safety in hot environments.
Published Warming waters and nutrient overload: A dangerous combination threatening our rivers and lakes
(via sciencedaily.com) Original source New international research found that food webs are becoming less complex in warmer, nutrient-rich waters.
Published Climate reporting standards insufficient, must be expanded, say experts
(via sciencedaily.com) Original source A new article concludes that current climate standards are not sufficiently incentivizing the big picture innovations necessary to deliver net zero, and must be expanded to include a company's broader influence on climate action.
Published A taste for carbon dioxide
(via sciencedaily.com) Original source The remarkable affinity of the microbial enzyme iron nitrogenase for the greenhouse gas CO2 makes it promising for future biotechnologies.
Published Fracking frenzy in India: A water crisis in the making?
(via sciencedaily.com) Original source India's plans to scale up fracking operations without robust regulations could spell disaster for the country's finely balanced water security, according to research.
