Published Climate change threatens Antarctic meteorites
(via sciencedaily.com) Original source Antarctica harbors a large concentration of meteorites imbuing the icy continent with an unparalleled wealth of information on our solar system. However, these precious meteorites are rapidly disappearing from the ice sheet surface due to global warming, according to a new study.
Published Ocean waves propel PFAS back to land
(via sciencedaily.com) Original source A new study reveals that PFAS re-emit into the air from crashing ocean waves at levels comparable to or greater than other sources, establishing a cyclical transport process for these 'forever chemicals' between land and sea.
Published eDNA methods give a real-time look at coral reef health
(via sciencedaily.com) Original source The study underscores the crucial role of microbes in maintaining coral reef health, akin to the human gut microbiome. Hurricanes and disease outbreaks affect coral reef water microbial communities, leading to changes that may support further reef decline. Microbial analysis enables prompt assessment of disturbances' impacts on coral reefs, facilitating timely interventions to support reef ecosystems. Environmental DNA (eDNA) analysis offers a noninvasive approach to study coral microbial communities and diagnose reef health.
Published Heat stress from ocean warming harms octopus vision
(via sciencedaily.com) Original source While climate change has led to an increase in the abundance of octopuses, heat stress from projected ocean warming could impair their vision and impact the survivability of the species.
Published Ocean floor a 'reservoir' of plastic pollution
(via sciencedaily.com) Original source New science has taken a deep dive into plastic waste, providing the first estimate of how much ends up on the sea floor.
Published What four decades of canned salmon reveal about marine food webs
(via sciencedaily.com) Original source Researchers have shown that levels of anisakid worms -- a common marine parasite -- rose in two salmon species in the Gulf of Alaska and Bristol Bay over a 42-year period. The team discovered this by studying salmon caught, killed and canned from 1979 to 2021. Since anisakid worms have a complex life cycle involving multiple types of hosts, the researchers interpret their rising numbers as a potential sign of ecosystem recovery, possibly driven by rising numbers of marine mammals thanks to the 1972 Marine Mammal Protection Act.
Published Researchers envision sci-fi worlds involving changes to atmospheric water cycle
(via sciencedaily.com) Original source Human activity is changing the way water flows between the Earth and atmosphere in complex ways and with likely long-lasting consequences that are hard to picture. Researchers enlisted water scientists from around the globe to write story-based scenarios about the possible futures humanity is facing but perhaps can't quite comprehend yet. The results are part of a creative pathway to understand atmospheric water research with an eye towards the potential economic and policy issues that may be just beyond the horizon.
Published Shy sea anemones are more likely to survive heatwaves
(via sciencedaily.com) Original source A study shows that sea anemones that react more slowly to change can survive a heatwave better than individuals that change their behavior quickly.
Published Tracing the largest solar storm in modern times from tree rings in Lapland
(via sciencedaily.com) Original source A research group was able to measure a spike in radiocarbon concentration of trees in Lapland that occurred after the Carrington flare. This discovery helps to prepare for dangerous solar storms.
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 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 Evolution in action? New study finds possibility of nitrogen-fixing organelles
(via sciencedaily.com) Original source A new study finds that UCYN-A, a species of nitrogen-fixing cyanobacteria, may be evolving organelle-like characteristics.
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.
