When the double boom rang out in New England over the weekend, shaking homes and sending pets fleeing, questions started flooding social media.
Newly created grassland habitats that compensate for nature lost to development can effectively support wild pollinators like bees and hoverflies, according to a first of its kind study in the Netherlands. The findings are published in the Journal of Applied Ecology.
Plastics, medicines, cosmetics—there are very few everyday products that do not rely on using fossil resources. A European research team led by Charité—Universitätsmedizin Berlin is now aiming to revolutionize this cornerstone of the chemical industry: as part of the CarboNcare project, scientists are developing bacteria that can produce important chemical base materials from sustainable methanol—thereby replacing fossil resources.
In early 2026, the EU extended its domestic carbon pricing to key products from beyond its borders. This is managed through the "Carbon Border Adjustment Mechanism" (CBAM). Exporters of polluting goods to the EU must pay a climate tariff, unless their country has its own pricing scheme.
In December 2025, Indonesia quietly abandoned plans to close the Cirebon-1 coal power plant.
NASA has completed its final inspection of the primary mirror on the Roman Space Telescope, which measures 2.4 meters (7.9 feet) in diameter and contains a layer of silver hundreds of times thinner than a human hair, at 400 nanometers.
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.
A research team from the School of Biomedical Sciences at the LKS Faculty of Medicine, the University of Hong Kong (HKUMed), has achieved a significant advance in biotechnology that could revolutionize treatment strategies for neurodegenerative diseases. The team has developed a novel tool called RNA Segment Editing (RSE), which functions like a "cut-and-patch" tool for RNA. This innovative approach allows scientists to precisely remove or replace faulty segments of genetic messages within living cells without permanently changing a person's DNA.
As another heavy sargassum season unfolds, many beachgoers are asking the same question: Is it safe to be near it? A recent University of Miami study offers an evidence-based answer, particularly for children. Overall risks are low, but not zero. The research, published in Exposure and Health, found that noncancer risks from arsenic exposure during beach play are minimal. But it also identified small increased cancer risks in certain scenarios, particularly from skin contact and accidental ingestion, underscoring the need to better understand how children interact with sargassum on the beach.
Cell function is determined by how DNA is expressed into proteins. That process includes two main steps—transcription, when messenger RNA (mRNA) makes copies of active genes; and translation, when mRNA guides protein assembly.
Scientists from six Asian countries have launched an ambitious 10-year effort to build synthetic cells from non-living molecules, marking the region's first coordinated push to create an artificial single-celled biological system. The roadmap, published on May 26 in Nature Biotechnology and led by the Shenzhen Institute of Advanced Technology of the Chinese Academy of Sciences, was developed through the SynCell Asia Initiative, which comprises more than 100 scientists from China, Japan, South Korea, Singapore, Thailand, and Malaysia.
