Much of Europe and parts of Africa and Asia saw the moon take a bite out of the sun during the second and last solar eclipse of the year.

NASA's Earth Surface Mineral Dust Source Investigation (EMIT) mission is mapping the prevalence of key minerals in the planet's dust-producing deserts—information that will advance our understanding of airborne dust's effects on climate. But EMIT has demonstrated another crucial capability: detecting the presence of methane, a potent greenhouse gas.

Soil moisture content is the main factor that controls how far and at what concentration natural gas spreads from a leaked pipeline underground, a new study has found.

New research led by the University of Massachusetts Amherst refines our understanding of the chemical traces that act as the rain's fingerprint. The work, which appeared recently in Global Biogeochemical Cycles, is crucial for understanding Earth's water cycle, especially as it undergoes rapid change due to global warming, deforestation and other environmental catastrophes.

Researchers at the University of Illinois Chicago have found a small molecule capable of manipulating an immune process that plays an important role in cancers and autoimmune diseases.

Today, the U.S. Fish and Wildlife Service (USFWS) announced that emperor penguins have been listed as a threatened species under the Endangered Species Act (ESA) based on evidence that the animal's sea ice habitat is shrinking and is likely to continue to do so over the next several decades. This listing comes more than one year after a USFWS proposal to list the species, and confirms that the...

A landmark with black spikes? A genetically modified blue forest? Or a document in an archive that somebody stumbles across? How can we warn humanity and other living organisms in 100,000 years of dangerous nuclear waste? These are questions that research colleagues Anna Storm and Thomas Keating at Linköping University are going to try and answer in their unique mission of writing warning texts...

Koalas—designated an endangered species in NSW, ACT and Queensland—are abundant in some parts of South Australia and Victoria, with Flinders University researchers now assessing whether their success in southern Australia can help save the species.

Climate change is shrinking the difference between the daily high temperature and the daily low in many parts of the world. The gap between the two, known as the diurnal temperature range (DTR), has a significant effect on growing seasons, crop yields, residential energy consumption and human health issues related to heat stress. But why and where the DTR shrinks with climate change has been...

New research out of Bowling Green State University is exploring the reasons for—and possible solutions to—widespread shortages among world language educators.

More than 50 animal species previously thought to be mute actually communicate vocally, according to a study published on Tuesday which suggested the trait may have evolved in a common ancestor over 400 million years ago.

Water-soluble synthetic polymers (WSSPs) are found in many everyday products. What the consequences are when these plastics enter rivers, lakes and oceans is still largely unexplored. A team from the University of Bayreuth has now systematically investigated the effects on water fleas of the species Daphnia magna for the first time.

A 5-year microbial study of the International Space Station (ISS) and its astronauts by Lawrence Livermore National Laboratory (LLNL) and NASA researchers has found that the ISS habitat is safe for its residents.

A strong earthquake rocked the northern Philippines late Tuesday, but officials said no serious damage was expected and no tsunami warning was issued.

Following years of research, scientists from the Bajo Laberinto Archaeological Project, a University of Calgary-led interinstitutional and multidisciplinary research project, in conjunction with Instituto Nacional de Antropología e Historia (INAH), Campeche, have utilized lidar (light detection and ranging) to help uncover more secrets of the enormous ancient Maya city of Calakmul. As a result,...

Scientists have shown that they can detect SARS-CoV-2, the virus that causes COVID-19, in the air by using a nanotechnology-packed bubble that spills its chemical contents like a broken piñata when encountering the virus.

As part of NASA's Artemis program to establish a long-term presence on the moon, it aims to build an Artemis base camp that includes a modern lunar cabin, rover and mobile home. This fixed habitat could potentially be constructed with bricks made of lunar regolith and saltwater, thanks to a recent discovery from a team of UCF researchers.

Scientists have revealed that there are two different variants, or genotypes of Moraxella bovis (M. bovis), a bacterium known to cause pinkeye in cattle. This finding helps scientists understand how different types of M. bovis cause infection in livestock and can help develop preventative measures to protect U.S. cattle against this disease.

The attack on the US Congress building in January 2021 was a violent manifestation of the deep political polarization in the US. Now Danish research shows that this attack caused even loyal party members to distance themselves from their party.

Birds attracted by the glow of artificial light at night are drawn into areas where they are also exposed to higher concentrations of airborne toxic chemicals, according to a new study.

Information on complex magnetic structures is crucial to understand and develop spintronic materials. Now, a new instrument named ALICE II is available at BESSY II. It allows magnetic X-ray scattering in reciprocal space using a new large area detector. A team at HZB and Technical University Munich has demonstrated the performance of ALICE II by analyzing helical and conical magnetic states of an...

Danes shuttle nearly a million tons of garden waste from their gardens every year. But we would be doing the climate a great service if we just left it alone, according to the calculations of University of Copenhagen professor Per Gundersen. At the same time, leaves and other garden waste are a boon for backyard biodiversity and soil.

Stradivarius violins produce elegant music with a level of clarity that is unparalleled by modern instruments, according to some musicians. And it's the finishing touches—mysterious treatments applied hundreds of years ago by Antonio Stradivari—that contribute to their unique look and sound. In a step toward unraveling the secret, researchers in Analytical Chemistry report on a nanometer-scale...

Fifteen years ago, the global population was almost evenly divided between urban and rural dwellers. In 2022, according to World Bank figures, almost a billion more people live in cities and towns than in the countryside. This relentless trend of urbanization has led to a rapid, often unchecked growth of cities, with sprawl stretching far out beyond previous limits.
