Recognizing liars from the sound of their voice?
Recognizing liars from the sound of their voice?
Faster speech rate, greater intensity in the middle of the word, and falling pitch at the end of the word: that is the prosody 1 to adopt if one wants to come across as reliable and honest to one's listeners. Scientists from the Science and Technology for Music and Sound laboratory (CNRS/Ircam/Sorbonne Université/Ministère de la Culture) 2 and the Perceptual Systems Laboratory (CNRS/ENS PSL) have conducted a series of experiments 3   to understand how we decide, based on the voice, whether a speaker is honest and confident, or on the contrary dishonest and uncertain.

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.

The CNRS welcomes France’s commitment to the construction and operation of the largest radio astronomy instrument ever built
The SKA Observatory will design and build the most sensitive radio astronomy instrument ever created, operating over an unmatched radio-wave range. It is expected to study the formation of the very first stars and galaxies shortly after the Big Bang. SKA will produce a data stream that exceeds today's global internet traffic and Facebook's current storage needs.

Team Paves the Way for Massive Integration of Qubits, Critical for Achieving Quantum Supremacy
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.

Exoplanets: SPIRou carries out first ever measurement of a very young planet's density
Exoplanets: SPIRou carries out first ever measurement of a very young planet’s density
A research team led by scientists from IRAP (CNRS/CNES/Université Toulouse III - Paul Sabatier) and IPAG (CNRS/UGA) 1 has for the first time measured the internal density of a very young exoplanet orbiting a newly formed, extremely active star. Despite the 'noise' generated by the star's activity, they successfully achieved this using the Canada-France-Hawaii Telescope (CFHT)'s planet hunting instrument SPIRou.

History of the Champagne vineyards revealed
History of the Champagne vineyards revealed
Although the reputation of Champagne is well established, the history of Champagne wines and vineyards is poorly documented. However, a research team led by scientists from the CNRS and the Université de Montpellier at the Institut des sciences de l'évolution de Montpellier 1 has just lifted the veil on this history by analysing the archaeological grape seeds from excavations carried out in Troyes and Reims.

CEA-Leti Reports Machine-Learning Breakthrough That Opens Way to Edge Learning
Article in Nature Electronics Details Method that Takes Advantage of RRAM Non- Idealities To Create Intelligent Systems that Have Potential Medical-Diagnostic Applications -GRENOBLE, France - Jan. 18, 2021 - CEA-Leti scientists have demonstrated a machine-learning technique exploiting what have been previously considered as "non-ideal" traits of resistive-RAM (RRAM) devices, overcoming barriers to developing RRAM-based edge-learning systems.

Saturn's tilt caused by its moons
Saturn’s tilt caused by its moons
Two scientists from CNRS and Sorbonne University working at the Institute of Celestial Mechanics and Ephemeris Calculation (Paris Observatory - PSL/CNRS) have just shown that the influence of Saturn's satellites can explain the tilt of the rotation axis of the gas giant. Rather like David versus Goliath, it appears that Saturn's tilt may in fact be caused by its moons.
