A study in Nature Communications used live electron microscopy to watch lithium metal form inside a working battery cell. The team found that the salt dissolved in the battery liquid can shape lithium’s first moments of growth, including whether it spreads into a smooth layer or erupts into dangerous spikes. Researchers led by Zhiyuan Zeng…
A study in Nature Communications found that Arctic river deltas hold a vast frozen reservoir of organic carbon and nitrogen. The international team estimates that these low-lying landscapes contain about 57.5 gigatonnes of carbon, equal to roughly 63.4 billion U.S. tons, along with about 4.2 billion tons of nitrogen. That hidden store sits in permafrost…
NASA’s Curiosity mission is surveying a puzzling sequence of exposed rock bands as the rover climbs Mount Sharp, using close-up imaging, chemistry measurements and long-distance views to track how the Martian landscape changes from one layer to the next. The June 12, 2026 planning update describes NASA’s Curiosity rover crossing a dark, rough-textured band of…
