Published Evolution might stop humans from solving climate change



Human culture has evolved to allow humans to extract resources and helped us expand to dominate the biosphere. But the same evolutionary processes may counteract efforts to solve new global environmental threats like climate change, according to a new study. Tackling the climate crisis will require worldwide regulatory, technical and economic systems supported by strong global cooperation. However, this new study concludes that the group-level processes characteristic of human cultural evolution, will cause environmental competition and conflict between sub-global groups, and work against global solutions. Adapting to climate change and other environmental problems will, therefore, require human evolution to change.
Published Understanding climate mobilities: New study examines perspectives from South Florida practitioners



A recent study assessed the perspectives of 76 diverse South Florida climate adaptation professionals. A new study explores the expectations and concerns of practitioners from the private sector, community-based organizations, and government agencies about the region's ability to adapt in the face of increasing sea level rise and diverse consequences for where people live and move, also known as climate mobility.
Published From NYC to DC and beyond, cities on the East Coast are sinking



Major cities on the U.S. Atlantic coast are sinking, in some cases as much as 5 millimeters per year -- a decline at the ocean's edge that well outpaces global sea level rise, confirms new research. Particularly hard hit population centers such as New York City and Long Island, Baltimore, and Virginia Beach and Norfolk are seeing areas of rapid 'subsidence,' or sinking land, alongside more slowly sinking or relatively stable ground, increasing the risk to roadways, runways, building foundations, rail lines, and pipelines, according to a new study.
Published Designing the 'perfect' meal to feed long-term space travelers



Imagine blasting off on a multiyear voyage to Mars, fueled by a diet of bland, prepackaged meals. As space agencies plan for longer missions, they're grappling with the challenge of how to best feed people. Now, researchers have designed the optimal 'space meal': a tasty vegetarian salad. They chose fresh ingredients that meet male astronauts' specialized nutritional needs and can be grown in space.
Published Global warming intensifies typhoon-induced extreme precipitation over East Asia



Scientists use a 3km high-resolution climate model to reveal expanded extreme rainfall from typhoons.
Published A carbon-lite atmosphere could be a sign of water and life on other terrestrial planets



Best chance of finding liquid water, and even life on other planets, is to look for the absence of carbon dioxide in their atmospheres.
Published Further evidence for quark-matter cores in massive neutron stars



New theoretical analysis places the likelihood of massive neutron stars hiding cores of deconfined quark matter between 80 and 90 percent. The result was reached through massive supercomputer runs utilizing Bayesian statistical inference.
Published Researchers study a million galaxies to find out how the universe began



Researchers have analyzed more than one million galaxies to explore primordial fluctuations that seeded the formation of the structure of the entire universe.
Published Astronomers detect seismic ripples in ancient galactic disk



A new snapshot of an ancient, far-off galaxy could help scientists understand how it formed and the origins of our own Milky Way. At more than 12 billion years old, BRI 1335-0417 is the oldest and furthest known spiral galaxy in our universe. The researchers were able to not only capture the motion of the gas around BRI 1335-0417, but also reveal a seismic wave forming -- a first in this type of early galaxy.
Published NASA's Hubble watches 'spoke season' on Saturn



A new photo of Saturn was taken by NASA's Hubble Space Telescope on October 22, 2023, when the ringed planet was approximately 850 million miles from Earth. Hubble's ultra-sharp vision reveals a phenomenon called ring spokes.
Published Supernova encore: Second lensed supernova in a distant galaxy



In November 2023, NASA's James Webb Space Telescope observed a massive cluster of galaxies named MACS J0138.0-2155. Through an effect called gravitational lensing, first predicted by Albert Einstein, a distant galaxy named MRG-M0138 appears warped by the powerful gravity of the intervening galaxy cluster. In addition to warping and magnifying the distant galaxy, the gravitational lensing effect caused by MACS J0138 produces five different images of MRG-M0138.
Published How national policies affect forests in border regions



How do national policies impact deforestation? Researchers have looked into this question at the global scale and have found that, contrary to common assumptions, national strategies have a significant -- and visible -- influence on efforts to protect forest heritage.
Published Millions of mysterious pits in the ocean decoded



The world's ocean are a vast habitat for countless creatures that settle, spawn, dig or feed on the seafloor. They also influence the shape of the ocean floor. How exactly this takes place has been scarcely investigated so far. In an interdisciplinary study, geoscientists, biologists and oceanographers, have examined crater-like depressions on the seafloor of the North Sea. They were able to show that these directly relate to the habitats of porpoises and sand eels, and for the first time provide a conclusive explanation for the importance of vertebrates in shaping the seafloor.
Published Cosmic lights in the forest



Supercomputer helped astronomers develop PRIYA, the largest suite of hydrodynamic simulations yet made of large-scale structure in the universe.
Published One small material, one giant leap for life on Mars: New research takes us a step closer to sustaining human life on the red planet



Researchers have discovered the transformative potential of Martian nanomaterials, potentially opening the door to sustainable habitation on the red planet.
Published Scientists uncover link between the ocean's weather and global climate



Scientists outline the first direct evidence linking seemingly random weather systems in the ocean with climate on a global scale. The team's work creates a promising framework for better understanding the climate system.
Published Reduced air pollution during pandemic points to way to preserve Himalayan glaciers



Reducing air pollution to levels similar to those during the coronavirus pandemic could protect the glaciers in the Himalayas and prevent them from disappearing by the end of the century. This is the conclusion reached by an international research team analyzing the situation during the COVID-19 lockdown in 2020.
Published Ringing in the holidays with ringed planet Uranus



NASA's James Webb Space Telescope recently trained its sights on unusual and enigmatic Uranus, an ice giant that spins on its side. Webb captured this dynamic world with rings, moons, storms, and other atmospheric features -- including a seasonal polar cap. The image expands upon a two-color version released earlier this year, adding additional wavelength coverage for a more detailed look.
Published Genetic sequencing uncovers unexpected source of pathogens in floodwaters



Researchers report that local rivers and streams were the source of the Salmonella enterica contamination along coastal North Carolina after Hurricane Florence in 2018 -- not the previously suspected high number of pig farms in the region.
Published Global inventory of sound production brings us one step closer to understanding aquatic ecosystems



Our understanding of which aquatic species produce sounds just took a big step forward. Scientists have created an inventory of species confirmed or expected to produce sound underwater.
