Sensors designed by Polish engineers help detect traces of life beyond Earth. Adam Piotrowski of Vigo System tells us what else these devices can do.

We discuss meal colors, food-drying secrets, and changing consumer demands with Dr. Anna Michalska from the PAS Institute of Animal Reproduction and Food Research in Olsztyn.

Cladoceran remains preserve selectively in lake sediments. Possibly all Cladocera species leave at least some identifiable remains in lake sediments. Exosceletal body parts of families Chydoridae and Bosminidae preserve best but other families are only variably represented in sediments by their outer body parts. Identification of all possible remains helps to achieve more precise palaeolimnological reconstruction of past ecosystems by Cladocera analysis. This article describes, together with photograph and line drawing the subfossil post-abdomen and post-abdominal claw of Ceriodaphnia, previously not widely identified.
