Published Researchers show that slow-moving earthquakes are controlled by rock permeability



A research group explores how the makeup of rocks, specifically their permeability -- or how easily fluids can flow through them -- affects the frequency and intensity of slow slip events. Slow slips' role in the earthquake cycle may help lead to a better model to predict when earthquakes happen.
Published Bee body mass, pathogens and local climate influence heat tolerance



How well bees tolerate temperature extremes could determine their ability to persist in a changing climate. But heat tolerance varies between and within populations, so entomologists examined bee physical traits to understand how these traits interact with environmental conditions, pathogens and other factors.
Published From fossils to fuel: Mozambique's Maniamba Basin's energy potential



In the ever-expanding search for energy resources, a new study has emerged from Mozambique's Maniamba Basin. Mozambique's Maniamba Basin could be a big source of natural gas.
Published DDT pollutants found in deep sea fish off Los Angeles coast



As the region reckons with its toxic history of offshore dumping off the California coast, new findings raise troubling questions about whether the banned pesticide remains a threat to wildlife and human health.
Published The Clues for Cleaner Water



By using experimental electrochemical analyses, mass spectrometry, and computational quantum chemistry modeling, the researchers created an 'atomic-scale storyline' to explain how ozone is generated on NATO electrocatalysts. They identified that some of the nickel in NATO is probably leaching out of the electrodes via corrosion, and these nickel atoms, now floating in the solution near the catalyst, can promote chemical reactions that eventually generate ozone.
Published Quantifying U.S. health impacts from gas stoves



A new study of air pollution in U.S. homes reveals how much gas and propane stoves increase people's exposure to nitrogen dioxide, a pollutant linked to childhood asthma. Even in bedrooms far from kitchens, concentrations frequently exceed health limits while stoves are on and for hours after burners and ovens are turned off.
Published Birdwatching can help students improve mental health, reduce distress



A new study finds people who have nature-based experiences report better well-being and lower psychological distress than those who do not. Birdwatching in particular yielded promising results, with higher gains in subjective well-being and more reduction in distress than more generic nature exposure, such as walks. Because birdwatching is an easily accessible activity, the results are encouraging for college students -- who are among those most likely to suffer from mental health problems.
Published Did a magnetic field collapse trigger the emergence of animals?



Researchers uncovered compelling evidence that Earth's magnetic field was in a highly unusual state when the macroscopic animals of the Ediacaran Period -- 635 to 541 million years ago -- diversified and thrived. Their study raises the question of whether these fluctuations in Earth's ancient magnetic field led to shifts in oxygen levels that may have been crucial to the proliferation of life forms millions of years ago.
Published In medieval England, leprosy spread between red squirrels and people, genome evidence shows



Evidence from archaeological sites in the medieval English city of Winchester shows that English red squirrels once served as an important host for Mycobacterium leprae strains that caused leprosy in people, researchers report.
Published New Nevada experiments will improve monitoring of nuclear explosions



On an October morning in 2023, a chemical explosion detonated in a tunnel under the Nevada desert was the launch of the next set of experiments by the National Nuclear Security Administration, with the goal to improve detection of low-yield nuclear explosions around the world.
Published New eco-friendly lubricant additives protect turbine equipment, waterways



Scientists have developed lubricant additives that protect both water turbine equipment and the surrounding environment.
Published For microscopic organisms, ocean currents act as 'expressway' to deeper depths



Some of the ocean's tiniest organisms get swept into underwater currents that act as a conduit that shuttles them from the sunny surface to deeper, darker depths where they play a huge role in affecting the ocean's chemistry and ecosystem, according to new research.
Published Human activity is causing toxic thallium to enter the Baltic sea, according to new study



Human activities account for 20% to more than 60% of toxic thallium entering the Baltic Sea over the past eight decades, according to new research. Currently, the amount of thallium, which is considered the most toxic metal for mammals, remains low in Baltic seawater. Much of the thallium in the Baltic, which is the largest human-induced hypoxic area on Earth, has been accumulated in the sediment thanks to sulfide minerals.
Published Sugar-based catalyst upcycles carbon dioxide



New catalyst is made from an inexpensive, abundant metal and table sugar. Catalyst converts carbon dioxide (CO2) into carbon monoxide, a building block for producing a variety of useful chemicals including syngas. With recent advances in carbon capture technologies, post-combustion carbon capture is becoming a plausible option to help tackle the global climate change crisis. But how to handle the captured carbon remains an open-ended question. The new catalyst potentially could provide one solution for disposing the potent greenhouse gas by converting it into a more valuable product.
Published Wild orangutan treats wound with pain-relieving plant



A wild orangutan was observed applying a plant with known medicinal properties to a wound, a first for a wild animal.
Published Artificial intelligence enhances monitoring of threatened marbled murrelet



Artificial intelligence analysis of data gathered by acoustic recording devices is a promising new tool for monitoring the marbled murrelet and other secretive, hard-to-study species.
Published EPA underestimates methane emissions from landfills, urban areas



The Environmental Protection Agency (EPA) is underestimating methane emissions from landfills, urban areas and U.S. states, according to a new study. The researchers combined 2019 satellite observations with an atmospheric transport model to generate a high-resolution map of methane emissions, which was then compared to EPA estimates from the same year. The researchers found: Methane emissions from landfills are 51% higher compared to EPA estimates Methane emissions from 95 urban areas are 39% higher than EPA estimates Methane emissions from the 10 states with the highest methane emissions are 27% higher than EPA estimates.
Published Feathers, cognition and global consumerism in colonial Amazonia



Amazonia is the home of the largest variety of birds in the world. In such a unique environment, craft cultures have flourished by translating the beauty and creativity of environmental materials like feathers into stunning pieces of art. A new article examines artisanal featherwork within the context of early modern colonialism and globalization.
Published Roadmap to close the carbon cycle



Reaching net-zero carbon emissions goals requires finding transformative paths to manage carbon in difficult-to-electrify economic sectors.
Published Missing link in species conservation: Pharmacists, chemists could turn tide on plant, animal extinction



As the world faces the loss of a staggering number of species of animals and plants to endangerment and extinction, one scientist has an urgent message: Chemists and pharmacists should be key players in species conservation efforts.
