WASHINGTON, D.C. — As wildfires grow more intense and frequent across the globe, scientists at the U.S. Naval Research Laboratory (NRL) are working to better understand a rare but powerful byproduct of these blazes: pyrocumulonimbus clouds, or pyroCbs.

Environmental engineers at Washington University in St. Louis develop hydrogels to transform wastewater nutrients to useful feedstocks and fertilizers.

Trace metals such as iron or zinc that are stored in deep-sea sediments are lost forever to phytoplankton on the ocean surface. This is what geochemists believed for a long time about the cycle of micronutrients in seawater. Now, researchers at ETH Zurich have discovered that this is not the case.Trace metals such as iron or zinc that are stored in deep-sea sediments are lost forever to phytoplankton on the ocean surface.
