Fossils reveal swimming patterns of long extinct cephalopod

Example image of how water flow shapes itself around one of our ammonoid models. Credit: University of Utah AmmLab Computational fluid dynamics can be used to study how extinct animals used to swim. Scientists studied 65 million-year-old cephalopod fossils to gain deeper understanding of modern-day cephalopod ecosystems. Three scientists affiliated with the University of Utah’s…

Changes in oxygen concentrations in our ocean can disrupt fundamental biological cycles

On Aug. 11, 2015, a NASA satellite captured this false-color image of a large bloom of cyanobacteria (Nodularia) swirling in the Baltic Sea. These cyanobacteria fix inorganic atmospheric nitrogen (N2) into a form available to Life, a process fundamental for marine ecosystems. In our paper we show that nitrogen fixation becomes even more important when…
