For years, countries have told the United Nations how much methane they emit using a kind of bottom-up bookkeeping: Count the cows and oil barrels, estimate the volume of trash, and multiply by standard emission factors.

Professor Dallas Trinkle and colleagues have provided the first quantitative explanation for how magnetic fields slow carbon atom movement through iron, a phenomenon first observed in the 1970s but never fully understood. ...

Researchers at the Nano Life Science Institute (WPI-NanoLSI), Kanazawa University, in collaboration with Osaka University and the National Institutes for Quantum Science and Technology, have uncovered a previously unknown ...

UCLA biologists are developing a tool to predict when deadly Salmonella outbreaks are likely to happen in wild songbird populations so that people can protect their feathered friends by taking down bird feeders at the right ...

An international team of scientists has developed ways to measure and compare the impact of "darkwaves"—when extreme weather events or human activities reduce underwater light for extended periods, affecting the stability ...

At times, the sun ejects energetic material into space, which can have consequences for space-based and even ground-based electronic technology. Researchers aim to understand this phenomenon and find ways to forecast it, ...

Challenging a 50-year-old narrative about Hawaiʻi's native birds, a new study from the University of Hawaiʻi at Mānoa found no scientific evidence that Indigenous People hunted waterbird species to extinction. Published ...

Excavated soil from construction sites usually ends up in landfills, but it has great potential. Researchers at the Technical University of Munich (TUM) show how excavated soil can be enriched with organic waste so that it ...

As marine-terminating glaciers melt, the resulting freshwater is released at the seafloor, which mixes with salty seawater and influences circulation patterns. As the oceans warm, it's growing increasingly important to study ...

Researchers at the University of Konstanz have developed a gentle, contact-free method to collect liquids and remove them from microscopic surface structures. The method uses vapor condensation to generate surface currents ...

Most people in the United States, United Kingdom, Germany, France, and Italy clearly endorse military support for Ukraine. They overwhelmingly reject Russia's positions on territorial claims and restrictions on Ukraine's ...

An international team of scientists has uncovered evidence glaciers in the Southern and Northern hemispheres were synchronous during the last ice age.
