Published Toward unification of turbulence framework -- weak-to-strong transition discovered in turbulence
(via sciencedaily.com) Original source Astrophysicists have made a significant step toward solving the last puzzle in magnetohydrodynamic turbulence theory by observing the weak to strong transition in the space plasma turbulence surrounding Earth with newly developed multi-spacecraft analysis methods.
Published Giant galactic explosion exposes galaxy pollution in action
(via sciencedaily.com) Original source Astronomers have produced the first high-resolution map of a massive explosion in a nearby galaxy, providing important clues on how the space between galaxies is polluted with chemical elements.
Published Lemur's lament: When one vulnerable species stalks another
(via sciencedaily.com) Original source What can be done when one threatened animal kills another? Scientists studying critically endangered lemurs in Madagascar confronted this difficult reality when they witnessed attacks on lemurs by another vulnerable species, a carnivore called a fosa.
Published Fourteen years after the Gulf of Mexico oil spill, endemic fishes face an uncertain future
(via sciencedaily.com) Original source The 2010 Gulf of Mexico Deepwater Horizon oil spill, the largest accidental spill in history, released almost 100 million gallons of oil, causing significant pollution. A decade later, its long-term effects remain unclear. A study investigating the impact on endemic fish species found 29 of 78 species unreported in museum collections since the spill, suggesting potential loss of biodiversity.
Published Marine microbial populations: Potential sensors of the global change in the ocean
(via sciencedaily.com) Original source Animal and plant populations have been extensively studied, which has helped to understand ecosystem processes and evolutionary adaptations. However, this has not been the case with microbial populations due to the impossibility of isolating, culturing and analyzing the genetic content of the different species and their individuals in the laboratory. Therefore, although it is known that populations of microorganisms include a great diversity, this remains largely uncharacterized.
Published 38 trillion dollars in damages each year: World economy already committed to income reduction of 19 % due to climate change
(via sciencedaily.com) Original source Even if CO2 emissions were to be drastically cut down starting today, the world economy is already committed to an income reduction of 19% until 2050 due to climate change, a new study finds. These damages are six times larger than the mitigation costs needed to limit global warming to two degrees. Based on empirical data from more than 1,600 regions worldwide over the past 40 years, scientists assessed future impacts of changing climatic conditions on economic growth and their persistence.
Published Dog attacks on mountain tapirs highlight a growing threat to endangered wildlife
(via sciencedaily.com) Original source Researchers who captured footage of dog attacks on endangered mountain tapirs in Colombia are calling for action to protect threatened wildlife.
Published Unique field study shows how climate change affects fire-impacted forests
(via sciencedaily.com) Original source During the unusually dry year of 2018, Sweden was hit by numerous forest fires. A research team has investigated how climate change affects recently burnt boreal forests and their ability to absorb carbon dioxide.
Published No gamma rays seen coming from nearby supernova
(via sciencedaily.com) Original source A nearby supernova in 2023 offered astrophysicists an excellent opportunity to test ideas about how these types of explosions boost particles, called cosmic rays, to near light-speed. But surprisingly, NASA's Fermi Gamma-ray Space Telescope detected none of the high-energy gamma-ray light those particles should produce.
Published Florida Wildlife Corridor eases worst impacts of climate change
(via sciencedaily.com) Original source Florida is projected to lose 3.5 million acres of land to development by 2070. A new study highlights how Florida can buffer itself against both climate change and population pressures by conserving the remaining 8 million acres of 'opportunity areas' within the Florida Wildlife Corridor (FLWC), the only designated statewide corridor in the U.S. Interactions between the FLWC and climate change had not been previously examined until now. Findings show substantial climate resilience benefits from the corridor, yielding a much higher return on investment than originally thought. About 90 percent of Floridians live within 20 miles of the corridor.
Published Biodiversity is key to the mental health benefits of nature
(via sciencedaily.com) Original source New research has found that spaces with a diverse range of natural features are associated with stronger improvements in our mental wellbeing compared to spaces with less natural diversity.
Published Tropical forests can't recover naturally without fruit-eating birds
(via sciencedaily.com) Original source Natural forest regeneration is hailed as a cost-effective way to restore biodiversity and sequester carbon. However, the fragmentation of tropical forests has restricted the movement of large birds limiting their capacity to disperse seeds and restore healthy forests.
Published Physicists solve puzzle about ancient galaxy found by Webb telescope
(via sciencedaily.com) Original source Physicists solve a puzzle linked to JWST-ER1g, a massive ancient galaxy that formed when the universe was just a quarter of its current age.

Published Brightest gamma-ray burst of all time came from the collapse of a massive star
(via sciencedaily.com) Original source In 2022, astronomers discovered the brightest gamma-ray burst (GRB) of all time. Now, astronomers confirm that a 'normal' supernova, the telltale sign of a stellar collapse, accompanied the GRB. The team also looked for signatures of heavy elements like gold and platinum in the supernova. They found no evidence of such elements, deepening the mystery of their origins.
Published Tropical coral-infecting parasites discovered in cold marine ecosystems
(via sciencedaily.com) Original source Parasites thought only to infect tropical coral reefs have been discovered in a large variety of creatures in cold marine ecosystems along the Northeast Pacific, according to new research.
Published Hybrid intelligence can reconcile biodiversity and agriculture
(via sciencedaily.com) Original source So far, biodiversity and agricultural productivity could not be reconciled because the socio-ecological system of agriculture is highly complex, and the interactions between humans and the environment are difficult to capture using conventional methods. A research team now shows a promising way to achieve both goals at the same time. They focus on further developing artificial intelligence in combination with collective human judgement: hybrid intelligence.
Published Ants in Colorado are on the move due to climate change
(via sciencedaily.com) Original source Ant species living in Boulder's foothills have shifted their habitat over the last six decades, potentially affecting local ecosystems, suggests a new study.
Published Deforestation harms biodiversity of the Amazon's perfume-loving orchid bees
(via sciencedaily.com) Original source A survey of orchid bees in the Brazilian Amazon, carried out in the 1990s, is shedding new light the impact of deforestation on the scent-collecting pollinators, which some view as bellwethers of biodiversity in the neotropics.
Published 'Teacher Toads' can save native animals from toxic cane toads
(via sciencedaily.com) Original source Scientists from Macquarie University have come up with an innovative way to stop cane toads killing native wildlife by training goannas to avoid eating the deadly amphibians.
