Published Adult fish struggle to bounce back in marine protected areas
(via sciencedaily.com) Original source Many marine protected areas are falling short of their most basic purpose: to rebuild struggling fish populations. In a new study, scientists looked at the age breakdown of reef fish in marine protected areas for the first time. They discovered in almost all of them, adult fish populations -- vital to spawning the next generation -- have either flatlined or declined.
Published With the planet facing a 'polycrisis', biodiversity researchers uncover major knowledge gaps
(via sciencedaily.com) Original source Connecting the study of infectious disease spread, biodiversity loss and climate change could offer win-win-win solutions for planetary health, but a new analysis has uncovered almost no research integrating the three global crises.
Published Fans are not a magic bullet for beating the heat!
(via sciencedaily.com) Original source A new study throws cold water on the idea that fans can effectively cool you down during extremely hot weather events.
Published Climate change impacts terrorist activity
(via sciencedaily.com) Original source Changing weather patterns induced by climate change are contributing to shifts in the location of terrorist activity, according to new research.
Published Out of the park: New research tallies total carbon impact of tourism at Yellowstone
(via sciencedaily.com) Original source New research makes a case study of Yellowstone National Park -- calculating surplus carbon that visitors from across the world add to the atmosphere each year as a direct result of a park visit.
Published 'Tug of war' tactic enhances chemical separations for critical materials
(via sciencedaily.com) Original source Lanthanide elements are important for clean energy and other applications. To use them, industry must separate mixed lanthanide sources into individual elements using costly, time-consuming, and waste-generating procedures. An efficient new method can be tailored to select specific lanthanides. The technique combines two substances that do not mix and that prefer different types of lanthanides. The process would allow for smaller equipment, less use of chemicals, and less waste production.
Published Experiencing extreme weather predicts support for policies to mitigate effects of climate change
(via sciencedaily.com) Original source Most Americans report having personally experienced the effects of extreme weather, according to new survey data. An analysis finds that a reported exposure to extreme weather is associated with support for a half-dozen pro-environmental government policies that are intended to mitigate the effects of climate change and are contained in the Inflation Reduction Act of 2022.
Published New tools reveal how genes work and cells organize
(via sciencedaily.com) Original source Researchers have discovered how certain proteins can attach to special structures in RNA, called G-quadruplexes. Additionally, they have developed computational tools capable of predicting these protein-RNA interactions. The newfound ability to predict these interactions can help future work in understanding molecular pathways in the cell and pave the way for developing drugs targeting these RNA G-quadruplex binding proteins, that are found to be involved in disease such as cancer.
Published For mining in arid regions to be responsible, we must change how we think about water
(via sciencedaily.com) Original source In an unprecedented study of the South American 'Lithium Triangle,' hydrologists discover that not all water responds the same way to environmental change and human use.
Published Giant phage holds promise as treatment for lung infections
(via sciencedaily.com) Original source Researchers have discovered a new bacterial killer that can target common lung infection caused by Burkholderia bacteria that has exciting potential for biotechnological applications.
Published Machine learning enables viability of vertical-axis wind turbines
(via sciencedaily.com) Original source Researchers have used a genetic learning algorithm to identify optimal pitch profiles for the blades of vertical-axis wind turbines, which despite their high energy potential, have until now been vulnerable to strong gusts of wind.
Published Plant-based plastic releases nine times less microplastics than conventional plastic
(via sciencedaily.com) Original source A newly developed plant-based plastic material releases nine times less microplastics than conventional plastic when exposed to sunlight and seawater, a new study has found.
Published Unleashing disordered rocksalt oxides as cathodes for rechargeable magnesium batteries
(via sciencedaily.com) Original source Researchers have made a groundbreaking advancement in battery technology, developing a novel cathode material for rechargeable magnesium batteries that enables efficient charging and discharging even at low temperatures.
Published California leads U.S. emissions of little-known greenhouse gas
(via sciencedaily.com) Original source California, a state known for its aggressive greenhouse gas reduction policies, is ironically the nation's greatest emitter of one: sulfuryl fluoride. As much as 17% of global emissions of this gas, a common pesticide for treating termites and other wood-infesting insects, stem from the United States. The majority of those emissions trace back to just a few counties in California, finds a new study.
Published Discovery could end global amphibian pandemic
(via sciencedaily.com) Original source A fungus devastating frogs and toads on nearly every continent may have an Achilles heel. Scientists have discovered a virus that infects the fungus, and that could be engineered to save the amphibians.
Published Plastic-free vegan leather that dyes itself grown from bacteria
(via sciencedaily.com) Original source Researchers have genetically engineered bacteria to grow animal- and plastic-free leather that dyes itself.
Published Magnetic fields boost clean energy
(via sciencedaily.com) Original source Researchers show that using magnetic fields can boost electrocatalysis for sustainable fuel production by enhancing the movement of the reactants, which improves the efficiency of energy-related reactions.
Published New discovery unravels malaria invasion mechanism
(via sciencedaily.com) Original source A recent breakthrough sheds light on how the malaria parasite, Plasmodium falciparum, invades human red blood cells. The study reveals the role of a sugar called sialic acid in this invasion process. The findings have major implications for malaria vaccine and drug development.
Published Testing environmental water to monitor COVID-19 spread in unsheltered encampments
(via sciencedaily.com) Original source To better understand COVID-19's spread during the pandemic, public health officials expanded wastewater surveillance. These efforts track SARS-CoV-2 levels and health risks among most people, but they miss people who live without shelter, a population particularly vulnerable to severe infection. To fill this information gap, researchers tested flood-control waterways near unsheltered encampments, finding similar transmission patterns as in the broader community and identifying previously unseen viral mutations.
Published Water-based paints: Less stinky, but some still contain potentially hazardous chemicals
(via sciencedaily.com) Original source Choosing paint for your home brings a lot of options: What kind of paint, what type of finish and what color? Water-based paints have emerged as 'greener' and less smelly than solvent-based options. And they are often advertised as containing little-to-no volatile organic compounds (VOCs). But, according to new research, some of these paints do contain compounds that are considered VOCs, along with other chemicals of emerging concern.
