For many decades, natural radioactive elements have been used to date the age of minerals and rocks, and also trace the geological origins of archaeological, organic and inorganic materials. Various methods have been explored to measure radioisotopes in often complex samples and retrieve information that may otherwise be lost from possibly eons ago. Patrick Degryse, Frank Vanhaecke, the new Chair for JAAS and others from Belgium have recently demonstrated a modern-day application of strontium isotopic analysis. The team has forensically identified human remains by determining the ⁸⁷Sr/⁸⁶Sr ratio of bone and tooth enamel using multi-collector ICP-mass spectrometry. Read more about their exciting discovery below!

Detecting Al³⁺ with the naked eye

Aluminium has many widespread applications including, packaging materials, food additives, clinical drugs, water purification, building construction etc. Too much Al can cause damage to the central nervous system, and is believed to have a role in neurodegenerative diseases such as Alzheimer’s disease and Parkinson’s disease. Debasis Das and colleagues from The University of Burdwan, India, have developed a highly sensitive fluorescent probe that can detect Al³⁺, with a green glow that can be seen by the naked eye.
