Part of the Universe’s missing matter found thanks to the MUSE instrument
CRAL publication in MNRAS , on September 16, 2021. CNRS press release on September 16, 2021. Galaxies can receive and exchange matter with their external environment thanks to the galactic winds created by stellar explosions. Thanks to the MUSE instrument  from the Very Large Telescope at the ESO, an international research team, led on the French side by the CNRS and l'Université Claude Bernard Lyon 1 , has mapped a galactic wind for the first time.

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.

New viable means of storing information for quantum technologies?
New viable means of storing information for quantum technologies?
Quantum information could be behind the next technological revolution. By analogy with the bit in classical computing, the qubit is the basic element of quantum computing. However, demonstrating the existence of this information storage unit and using it remains complex, and hence limited.

The final dance of mixed neutron star-black hole pairs
The final dance of mixed neutron star-black hole pairs
Gravitational wave detectors have observed a new type of cataclysmic event in the cosmos: the merger of a neutron star with a black hole. The phenomenon was detected twice in January 2020. Several hypotheses could explain the existence of such mixed pairs. Further observations will be needed in order to settle the question.  Another missing piece has just been added to our knowledge of cosmic phenomena.

French ESA astronaut Thomas Pesquet to continue experiments on foams
French ESA astronaut Thomas Pesquet to continue experiments on foams
Studying how liquid foams evolve over time is difficult, if not impossible, on Earth because of gravity. The FOAM-C experiment, which began in 2020, was designed to study liquid foams in zero gravity on board the ISS. New samples will be set up by French astronaut Thomas Pesquet on Friday, June 11. The FOAM-C experiment studies the properties of liquid foams in zero gravity.

Particle physics: will muons lead us towards a new physics?
Particle physics: will muons lead us towards a new physics?
Muons, particles akin to electrons, have kept physicists' heads spinning for more than a decade, because an experimental measurement of their magnetic properties 1 disagrees from theory. Could this be caused by unknown particles or forces? A new theoretical calculation of this parameter, involving CNRS physicists and published , has reduced the discrepancy with the experimental measurement.

Astronomers Image Magnetic Fields at the Edge of M87's Black Hole
Astronomers Image Magnetic Fields at the Edge of M87’s Black Hole
Within the EHT collaboration, the CNRS and IRAM participated in the creation of a new image of the black hole in the M87 galaxy. Produced in so-called "polarized" light, this image makes it possible to observe the magnetic field and to better understand the physics around black holes. The Event Horizon Telescope (EHT) collaboration, who produced the first ever image of a black hole , has revealed today a new view of the massive object at the centre of the M87 galaxy: how it looks in polarised light.

The quantum advantage: a novel demonstration
A + A Is a quantum machine really more efficient than a conventional machine for performing calculations? Demonstrating this 'advantage' experimentally is particularly complex and a major research challenge around the world 1. Scientists from the CNRS 2 , the University of Edinburgh (Scotland) and the QC Ware, Corp., (France and USA) have just proved that a quantum machine can perform a given verification task in seconds when the same exercise would take a time equivalent to the age of the universe for a conventional computer.

Team Paves the Way for Massive Integration of Qubits, Critical for Achieving Quantum Supremacy
GRENOBLE, France - Feb. 4, 2021 - CEA-Leti scientists have opened a pathway to large-scale integration of Si-spin qubits using existing flip-chip processes with die-to-wafer 3D-interconnect technologies developed in-house. In a paper presented during the 2020 Electronics System-Integration Technology Conference (ESTC), the team reported preliminary electrical characterizations at cryogenic temperatures of chip assemblies made with 3D interconnects such as SnAg microbumps and direct Cu bonded pads from Cu/SiO 2 hybrid bonding process.

Has the hidden matter of the Universe been discovered?
Has the hidden matter of the Universe been discovered?
Astrophysicists consider that around 40% of the ordinary matter that makes up stars, planets and galaxies remains undetected, concealed in the form of a hot gas in the complexe cosmic web. Today, scientists at the Institut d'Astrophysique Spatiale (CNRS/Université Paris-Saclay) may have detected, for the first time, this hidden matter through an innovative statistical analysis of 20-year-old data.  Their findings are published on November 6, 2020 in Astronomy & Astrophysics .

Towards next-generation molecule-based magnets
Magnets are to be found everywhere in our daily lives, whether in satellites, telephones or on fridge doors. However, they are made up of heavy inorganic materials whose component elements are, in some cases, of limited availability.   Now, researchers from the CNRS, the University of Bordeaux and the ESRF (European Synchrotron Radiation Facility in Grenoble) 1 have developed a new lightweight molecule-based magnet, produced at low temperatures, and exhibiting unprecedented magnetic properties.

New populations of black holes revealed by gravitational waves
The gravitational wave 1 detectors LIGO and Virgo have just chalked up their biggest catch yet, a black hole 142 times the mass of the Sun, resulting from the merger of two black holes of 85 and 66 solar masses.  The remnant black hole is the most massive ever observed with gravitational waves, and it could give us some clues about the formation of the supermassive black holes that sit at the centres of some galaxies.
