New method helps identify hormone-disrupting chemicals—without animal testing

A new study from the Institute of Environmental Medicine at Karolinska Institutet presents a promising method for identifying endocrine-disrupting chemicals—without the need for traditional animal testing. By combining RNA-sequencing of zebrafish embryos with a structured toxicological framework, researchers can now better predict harmful effects on human health.
