Micro- and nanoplastics cause stress to crops such as lettuce and carrots, PhD candidate Laura Julia Zantis found. This can lead to reduced growth and a lower nutritional value. Biodegradable plastics have this effect too, likely because of chemicals they release during degradation.

For the first time, an international team of scientists led by Leiden Observatory and SRON can explain the extreme jet streams observed around the equators of all the giant planets using a single model.
