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 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 NASA's Webb probes an extreme starburst galaxy
(via sciencedaily.com) Original source A team of astronomers has used NASA's James Webb Space Telescope to survey the starburst galaxy Messier 82 (M82). Located 12 million light-years away in the constellation Ursa Major, this galaxy is relatively compact in size but hosts a frenzy of star formation activity. For comparison, M82 is sprouting new stars 10 times faster than the Milky Way galaxy.
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 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 Groundbreaking research in groundwater's role in ecosystem sustainability
(via sciencedaily.com) Original source Until now, groundwater -- a critical water resource around the globe, especially in dry regions -- has been largely unstudied in its importance and role in sustaining ecosystems. New groundbreaking research examines the relationship between groundwater and ecosystems across California.
Published First results from BREAD experiment demonstrate a new approach to searching for dark matter
(via sciencedaily.com) Original source One of the great mysteries of modern science is dark matter. We know dark matter exists thanks to its effects on other objects in the cosmos, but we have never been able to directly see it. And it s no minor thing currently, scientists think it makes up about 85% of all the mass in the universe.
Published Scientists' urgent call: End destruction and forge a just, sustainable future
(via sciencedaily.com) Original source An international team of scientists published a study emphasizing the urgent need to align political will, economic resources, and societal values to ensure a more sustainable and equitable world. The review summarizes the grave threats facing the planet but rejects a 'doom and gloom' philosophy. They advocate a global cultural shift that elevates kinship with nature and communal well-being, underpinned by the recognition of Earth's finite resources and the interconnectedness of its inhabitants.
Published Older trees help to protect an endangered species
(via sciencedaily.com) Original source The oldest trees in the forest help to prevent the disappearance of endangered species in the natural environment, according to a new study. This is the case of the wolf lichen -- threatened throughout Europe --, which now finds refuge in the oldest trees in the high mountains of the Pyrenees. This study reveals for the first time the decisive role of the oldest trees in the conservation of other living beings thanks to their characteristic and unique physiology.
Published New method reveals hidden activity of life below ground
(via sciencedaily.com) Original source Researchers have refined an innovative method for measuring the activity level of microbes and linking that to their individual genetic code, providing new insights into the microbial communities that thrive in extreme environments.
Published Melting glaciers in a warmer climate provide new ground for invasive species
(via sciencedaily.com) Original source In 2022 and 2023, biologists from research institutes in the UK and the Falkland Islands led two expeditions to South Georgia to study the impacts of invasive species on this cold and rugged sub-Antarctic island. They report that several invasive plants and invertebrates rapidly colonized the new ground exposed by melting glaciers, leaving few pristine areas for native species. With ongoing climate change, more research is needed across the world to understand how invasive species impact the fragile ecosystems that develop after glacier melting.
Published Manganese plays a surprising role in soil carbon sequestration
(via sciencedaily.com) Original source A recent study reveals an unexpected link between manganese -- a naturally occurring mineral -- and increased carbon emissions from high-latitude boreal forests. The study uncovers how manganese increases carbon emissions from boreal forest soil, over time, challenging conventional understanding of the role of manganese in the carbon cycle.
Published New approach to monitoring freshwater quality can identify sources of pollution, and predict their effects
(via sciencedaily.com) Original source Analysing the diversity of organic compounds dissolved in freshwater provides a reliable measure of ecosystem health, say scientists.
Published Unlocking supernova stardust secrets
(via sciencedaily.com) Original source New research has discovered a rare dust particle trapped in an ancient extra-terrestrial meteorite that was formed by a star other than our sun.
Published ALMA finds new molecular signposts in starburst galaxy
(via sciencedaily.com) Original source The ALMA radio telescope has detected more than 100 molecular species, including many indicative of different star formation and evolution processes, in a galaxy where stars are forming much more actively than in the Milky Way. This is far more molecules than were found in previous studies. Now the team will try to apply this knowledge to other galaxies.
Published Open waste burning linked to air pollution in Northwestern Greenland
(via sciencedaily.com) Original source A case study on the effects of open waste burning on air quality in Northwestern Greenland calls attention to the importance of no-one-left-behind sustainable air quality monitoring in the Arctic region.
Published Going 'back to the future' to forecast the fate of a dead Florida coral reef
(via sciencedaily.com) Original source How coral populations expand into new areas and sustain themselves over time is limited by the scope of modern observations. Going back thousands of years, a study provides geological insights into coral range expansions by reconstructing the composition of a Late Holocene-aged subfossil coral death assemblage in an unusual location in Southeast Florida and comparing it to modern reefs throughout the region. Findings offer a unique glimpse into what was once a vibrant coral reef assemblage and discover if history can repeat itself in the face of climate change.
Published Artificial reef designed by MIT engineers could protect marine life, reduce storm damage
(via sciencedaily.com) Original source Engineers designed an 'architected' reef that can mimic the wave-buffering effects of natural reefs while providing pockets for marine life. The sustainable and cost-saving structure could dissipate more than 95 percent of incoming wave energy using a small fraction of the material normally needed.
Published Astronomers conduct first search for forming planets with new space telescope
(via sciencedaily.com) Original source Planets form in disks of dust and gas called protoplanetary disks that whirl around a central protostar during its final assembly.
Published North American cities may see a major species turnover by the end of the century
(via sciencedaily.com) Original source Climate change may dramatically affect the animal species observed in North American cities, according to a new study.
