Phys.org / ExoMars rover targets vast bed of clay in search for life
In the region where the ExoMars Rosalind Franklin rover will search for signs of life, clay deposits extend beyond previous estimates, a new study finds. One hypothesis even suggests a vast ocean once covered the landing ...
Phys.org / Easily overlooked small wetlands are a big source of global methane
Waterlogged land areas such as marshes, bogs and fens are the world's largest natural source of methane. Even the smallest of wetlands emit this powerful greenhouse gas. In a study from The University of Texas at Austin, ...
Phys.org / Smarter land use could unlock biodiversity, climate and economic gains across 146 countries
National governments and multilateral institutions face difficult challenges reconciling environmental goals, such as biodiversity conservation and addressing climate change, with economic development goals. In a first-of-its-kind ...
Phys.org / Wildfires reverse decade of ozone cleanup in the United States, study reveals
Ozone pollution has worsened in much of the continental United States over the past decade, fueled by wildfires and the long-distance transport of unhealthy air, according to a new study titled "Fires reverse progress toward ...
Phys.org / Why jellyfish can't rise to the surface
Using box jellyfish as an example, researchers from Kiel University show how the physics of density, not behavior or physiology, can prevent animals from reaching the surface even as they actively swim upward.
Phys.org / Endangered basking sharks rely on the ocean twilight zone during long-distance migrations
Endangered basking sharks aren't fasting during long-distance migrations. A new study led by the Woods Hole Oceanographic Institution shows that they may be foraging along the way, and in much deeper areas of the ocean than ...
Phys.org / Global mangrove forests rebound, offering hopeful sign for climate and coastal resilience
Mangrove forests, once considered one of the world's most threatened coastal ecosystems, are showing signs of recovery worldwide, according to new research from Tulane University that finds decades of losses largely offset ...
Phys.org / New gold-palladium catalysis mechanism could advance bio-based chemical manufacturing
The building‐block chemicals behind everyday products—like shampoo bottles, food containers, and kitchen spatulas—are largely derived from oil. Researchers are now working to replace those fossil‐fuel‐based inputs with materials ...
Phys.org / What makes 15-minute cities work? More nearby jobs and connected streets
The concept of the "15-Minute City" has gained global traction as a blueprint for more livable, sustainable communities by placing daily essentials—such as grocery stores, schools, restaurants and parks—within easy reach ...
Phys.org / Teaching AI to design optical surfaces using real-world imperfections
Designing surfaces that precisely control how light behaves at the nanoscale is tricky. Optical Fourier surfaces, which are nanostructured gratings that redistribute light into specific directions and wavelengths, hold enormous ...
Phys.org / Moms' learned fear of snakes gets inherited by offspring in a critically endangered mouse, biologists discover
Conservationists often raise the young of endangered species in captivity before releasing them into suitable habitats as adults. The benefits are obvious: survival to adulthood is typically high, as captive animals are safe ...
Phys.org / 'Out-of-place' rocks reveal how a young ocean formed
Deep below the Tyrrhenian Sea offshore Italy, scientists drilled into what they thought would be dark mantle rock—and found pieces of granite that seemingly had no business being there. Those unexpected intrusions turned ...
