The Ariane 5 rocket is a workhorse for delivering satellites and other payloads into orbit, but fitting the James Webb Space Telescope (JWST) inside one is pushing the boundaries of the Ariane 5’s capabilities, and advancing our design of space […]

Image: Hawaii Volcano Observatory (DAS) It has long been observed that some volcanoes erupt with little prior warning. Now, scientists have come up with an explanation behind these sudden eruptions that could change the way observers monitor active or dormant volcanoes. Previously, it was thought eruptions were triggered by a […]


A new Yale-led study offers a new conceptual framework for understanding the biogeochemistry of watersheds. The framework combines hydrologic and biogeochemical theory to test well established concepts in watershed ecology. The paper, published in the journal Ecology, suggests that heavy weather events, though infrequent, cause an inordinate amount of organic […]
