Nuclear Fusion: A Historic Breakthrough
In December 2022, scientists at the National Ignition Facility (NIF) announced a "historic breakthrough" in the field of nuclear fusion. They succeeded, for the first time, in releasing more energy through fusion reactions than was necessary to cause them. Caterina Riconda, professor of physics at Sorbonne University in the Laboratory for the Use of Intense Lasers, and Pierre Morel, associate professor at the Laboratory of Plasma Physics, discuss these unprecedented results.

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.

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.

Invited CEA-Leti Paper at IEDM 2021 Identifies Main Challenges Facing Large-Scale Si Quantum Computing
SAN FRANCISCO - Dec. CEA, in collaboration with CNRS Néel, a leading team in SI-based quantum c'omputing, presented two papers on that topic at IEDM 2021, including an invited paper that identifies the material and integration challenges facing large-scale Si quantum computing. The second paper presents a novel Si quantum device integration that reduces by half the effective gate pitch and provides full controllability in 1D FD-SOI quantum dot (QD) arrays.

Einstein wins in the end (once again)
Einstein wins in the end (once again)
Einstein's theory of gravity, general relativity, has not been disproven once in over a century, despite relentless efforts from scientists to find its faults. Pulsars are stars toward the end of the stellar life cycle, emitting radio waves that sweep through space like a lighthouse: they can be detected by radio telescopes in the form of highly regular flashes.

An artificial ionic neuron for tomorrow's electronic memories
An artificial ionic neuron for tomorrow’s electronic memories
Artificial intelligence surpasses the human brain only at the cost of consuming tens of thousands of times more energy. A major difference between the brain and electronic systems is that neurons use ions, not electrons, to carry information. French scientists have designed theoretical artificial neurons with ions to carry the information.
