Early in vitro testing for adverse effects on embryos

ETH researchers have combined embryonic cells and liver cells in a new cell culture test. This combination lets them detect adverse effects that new medications may have on embryos early on in the drug development process.

Turning wastewater sludge into energy and mineral salts

A system developed by EPFL spin-off TreaTech can turn sludge from wastewater treatment plants into mineral salts – which could be used in fertilizer, for example – and biogas. The firm's research is being funded by several ...
