When it comes to understanding Earth and our changing environment, space is the place. Not only does it give us an overall holistic view of the planet below, but satellite-based imagery can transcend national boundaries and give us an understanding of key changes that often go unseen at ground level.
The "soil" blanketing the moon's surface isn't actually soil. It's a fine, lethal, abrasive powder of shattered rock and jagged glass that shreds gaskets, chews through seals, and hangs in an airless environment blasted by unfiltered radiation and temperature swings that can warp steel. Scientists call it lunar regolith.
Textile wastewater treatment practices inadvertently produce toxic byproducts—including chloroform and bromoform—at alarming levels that pose a clear occupational health hazard and lead to unknown environmental effects downstream, University of Massachusetts Amherst researchers have found. The study is published in the Journal of Hazardous Materials.
Climate change and sea level rise are altering the chemistry of Biscayne Bay in ways that could threaten South Florida's coastal ecosystems, water resources, fisheries, and recreation, according to a study led by scientists from the University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science and Miami-Dade County's Department of Environmental Resources Management. Researchers found that over the past 20 years, Biscayne Bay has become warmer, saltier, and more acidic.
By using clearcutting, industrial forestry has caused a large-scale decline of hair lichens in Sweden's forests. In a large-scale field-experiment, researchers from Umeå University, University of Northern British Columbia, Canada, and Norwegian University of Life Sciences have shown that partial cutting can increase the abundance of hair lichens. The study is published in Forest Ecology and Management.
The Langobards are frequently depicted as fierce warrior-like people, with all known archaeological evidence of violence restricted to men. However, nearly 1,400 years ago, a Langobard woman took two severe injuries to the head, one a clean slice made by a blade, the other a crushing blow, making her the first direct evidence of interpersonal violence in Langobard females.
Conical intersections are crucial molecular switching points in light-driven reactions, but accurately predicting them usually requires computations. A researcher from Shibaura Institute of Technology has developed a new low-cost quantum chemistry method that can simultaneously describe ground and excited molecular states while efficiently locating these elusive structures. The approach reproduces benchmark geometries with strong accuracy and enables practical simulations of photochemical processes, making it promising for applications in photocatalysis, solar cells, and biological light-response studies.
New research from the University of Oxford provides the first quantitative evidence that drought exposure over the last 12 months is associated with an increased risk of sexual, emotional and physical violence among adolescents in Southern Africa. This risk rises substantially during cumulative droughts over two years.
Mid-latitude Asian drylands, stretching from Central Asia to northern China, are among the largest dryland systems in the world. Home to extensive agricultural activities and fragile ecosystems, the region is highly vulnerable to climate change and water scarcity.
How does nature build one of the most sophisticated catalytic metal centers found in biology? An international team of researchers has now resolved a long-standing debate surrounding the assembly of the active site of [FeFe]-hydrogenases—enzymes that rank among nature's most efficient catalysts for hydrogen production and consumption.
