Investigation of misconduct in research: Study of fishes’ consumption of plastic

In June 2016 a scientific article was published in the journal Science describing how fish in early developmental stages consume microplastics. The study gained significant attention but was reported for misconduct in research by another group of researchers. Uppsala University has not yet taken a decision in the matter.
