Fun with filtering: small vs. ultra-small

Our Constructor University team (Adrienne, Natasha and Polina) is focused on collecting size-fractionated data for trace metals and metal-binding ligands. Specifically, we are collecting samples for high field-strength elements (HFSE), oxyanions, metal-binding organic ligands (Cu, Fe, Ni) and Cr and V speciation. Of these parameters, I am personally the most interested in organic ligands, which […]

„I found an Alien!”

Svenja burst into the red lounge, where a group of scientists were having a post-prandial chat. The alien announcement was irresistible, and we trooped down to the lab where Svenja’s fresh multinet haul was awaiting earthly attention.  Under the microscope we saw live zooplankton hopping, spiralling, leapfrogging and swimming through the sample. Then, carefully teased […]
