Mass spectrometry sheds new light on thallium poisoning cold case

In 1994, Chinese university student Zhu Ling began experiencing stomach pain, hair loss and partial paralysis. By the time doctors diagnosed Ling with thallium poisoning about four months later, she was in a coma. Ling survived, ...

Scientists improve an X-ray fluorescence analysis algorithm

Scientists from the Faculty of Chemistry of the Lomonosov Moscow State University have performed computations and derived new equations to conduct X-ray fluorescence analysis with higher accuracy in comparison to current ...

NIST releases new 'family' of standardized genomes

With the addition of four new reference materials (RMs) to a growing collection of "measuring sticks" for gene sequencing, the National Institute of Standards and Technology (NIST) can now provide laboratories with even more ...

Developing new methods to detect nanoparticles in food

The production and characterisation of reference materials to detect silver nanoparticles in meat is feasible, a recent experiment has found. Using methods developed through the NANOLYSE project, two concentrations of silver ...

Hidden uncertainties uncovered in nuclear forensic measurement

A little detective work by nuclear physicists has uncovered hidden uncertainties in a popular method for precisely measuring radioactive nuclides, often used to make reference materials for forensic analyses such as radioactive ...
