Forever chemicals affect the genes of unhatched ducklings

Researchers discover that PFAS can harm ducklings even before they hatch, altering their gene expression and potentially affecting their fat metabolism and immune system. The findings support demands for a blanket EU ban on the substances, which are considered 'forever chemicals' due to their long-term persistence in the environment.

Fish reveal cause of altered human facial development

Researchers tested five chemicals on zebrafish embryos and found that all caused impaired migration of bone-forming cells, leading to facial malformation. The study suggests a potential general mechanism underlying teratogenic chemicals and proposes using zebrafish as an alternative method for testing cross-species teratogens.
