Tracing the Novichok Trail

How scientists are tracing the novichok trail in the UK using “hotzone” forensics – using mass spectrometry to work out where the nerve agent could have been originally placed.

How are scientists looking for the trail of the novichok nerve agent used in the Salisbury attacks? Roland Pease speaks to Steven Drielak a “hotzone” forensics expert, who explains the techniques he would use when investigating environmental chemical crimes.

Mircroplastics on land and in rivers
Much has been covered about microplastics in our oceans, but now Professor Chelsea Rochman from the University of Toronto reviews the evidence for their presence in freshwater and in soil.
