Iceberg calving happens when large pieces of ice split from the front of a glacier and fall into the ocean. This natural event is a major contributor to the rapid reduction of ice on the Greenland ice sheet. For the first time, an international team led by the University of Zurich (UZH) and the University…

Many familiar items, from plastic squeeze bottles to outdoor furniture, rely on a process that converts propane into propylene. In 2021, a study in Science showed that chemists could use tandem nanoscale catalysts to merge several steps of this conversion into a single reaction — an approach that increases yield and reduces costs. However, the…

A galaxy called NGC 6789, as seen by the Two-meter Twin Telescope Ignacio Trujillo et al 2025 About 12 million light years away lies an impossible galaxy. Over the last 600 million years, its core has been forming new stars – but there is no apparent source for the fuel that has fed that star…

Researchers at Rice University have found that certain atom-thin semiconductors, known as transition metal dichalcogenides (TMDs), can physically shift their atomic lattice when exposed to light. This newly observed response offers a controllable way to tune the behavior and properties of these ultrathin materials. The phenomenon appears in a subtype of TMDs called Janus materials,…

The skin and muscle of Yuka’s front left leg are exceptionally well preserved Love Dalen A woolly mammoth that was frozen in the Siberian permafrost for nearly 40,000 years has yielded the world’s oldest RNA. The specimen, found in 2010 and nicknamed Yuka, is regarded as the best-preserved woolly mammoth (Mammuthus primigenius) ever found. Yuka…

Astronomers working with the European Space Agency’s XMM-Newton observatory and the LOFAR radio telescope have obtained clear evidence of a violent burst of material hurled into space by a distant star. The outflow was strong enough that any nearby planet in its path would likely have its atmosphere stripped away. This burst was identified as…

A recently uncovered and unusually intact impact crater is offering scientists new insights into how objects from space have struck Earth throughout its history. Researchers from Shanghai and Guangzhou, China, describe their findings in the journal Matter and Radiation at Extremes (AIP Publishing). They identified the feature as the Jinlin crater, a bowl-shaped structure positioned…
