Quantum sensors for GPS-free orientation
Quantum sensors for GPS-free orientation
How can we navigate airliners or allow military vehicles to stay on course without GPS or satellite signals? This is a problem for which quantum inertial sensors offer a solution. Harnessing quantum technology, they can take ultrasensitive measurements of acceleration in three dimensions, and in any orientation.

Plastics response to extreme stretching
By coupling a tensile machine and an in situ dielectric measurement, physicists from Lyon (ENS de Lyon Physicis Laboratory and MATEIS) have made a breakthrough in understanding the molecular reorganizations that allow a polymer film to stretch. The results of this study are published in the journal Macromolecules .

The James Webb telescope: first images of the Orion Nebula
The James Webb telescope: first images of the Orion Nebula
The James Webb telescope has delivered extraordinary new images of the Orion Nebula. Many stars are born in this nebula, hence these observations could yield information on the origins of our Solar system. The new images were obtained by a team headed by French and Canadian researchers. An international research team has released the first images of the Orion Nebula, the closest richly productive stellar nursery to our own solar system.

Manipulating chromosomes in living cells reveals that they are fluid
Manipulating chromosomes in living cells reveals that they are fluid
Chromosomes are fluid - almost liquid - outside their division phases. This discovery was made possible thanks to the direct mechanical manipulation, for the very first time, of chromosomes in the nucleus of living cells. Until then, chromosomes - which are very long DNA molecules - were represented as being entangled like loose balls of yarn, and forming a sort of gel.

A 'Nano-Robot' Built Entirely from DNA to Explore Cell Processes
A ’Nano-Robot’ Built Entirely from DNA to Explore Cell Processes
Constructing a tiny robot from DNA and using it to study cell processes invisible to the naked eye. You would be forgiven for thinking it is science fiction, but it is in fact the subject of serious research by scientists from Inserm, CNRS and Université de Montpellier at the Structural Biology Center in Montpellier .
