Fruiting bodies: Full metal mushroom

Date: Apr 15, 2016

Author: David Bradley

It is assumed that edible mushrooms are full of natural goodness, but a new inductively coupled plasma atomic emission spectroscopy (ICP-OES) and cold vapour atomic absorption spectrometry (CV-AAS) study reveals that while at least one species may be rich in essential trace metals it can also contain toxic elements such as mercury.

Right on time: Strontium clock

Date: Feb 15, 2016

Author: David Bradley

An analysis by researchers in Germany of the processes that generate noise in their optical lattice clock demonstrates that this optical strontium atomic clock has the greatest stability of any such device thanks to a newly developed laser system.

Build a safer battery: Spectroscopic assistance

Date: Jan 8, 2016

Author: David Bradley

A new material that can rapidly shut down an overheating lithium-ion rechargeable battery and once cool, quickly restore power has been described by US researchers in the journalNature Energy. The highly thermoresponsive material could make a wide range of battery-powered electronic devices much safer than they currently are.
