After cutting a thin section from one of the carbon globules of the meteorite, they used a jet of argon ions to erode the slice until it was just 50 nanometres thick — a process known as ion milling — and examined it under an electron microscope.

They are confident they can extend the tunable range to wavelengths from 650 to 1100 nanometres, which can pass through living tissue, and have devised a laser which could cost around # 10 000.

Drivers will use electrons from the tip of a scanning tunnelling microscope (STM) to help jolt their molecules along, typically by just 0.3 nano - metres each time — making 100 nanometres «a pretty long distance», notes physicist Leonhard Grill of the University of Graz, Austria, who co-leads a US — Austrian team in the race.

Scientists from MIPT have succeeded in growing ultra-thin (2.5 - nanometre) ferroelectric films based on hafnium oxide that could potentially be used to develop non-volatile memory elements called ferroelectric tunnel junctions.
