How best to evaluate the performance of a group testing strategy for the SARS-CoV-2 virus, which involves pooling samples from multiple individuals in order to conduct a single RT-PCR test on the whole group? To do precisely that, scientists from the CNRS, l'université Grenoble Alpes, and l'université Sorbonne Paris Nord 1 have developed a model that evaluates the efficiency of such tests.
Ecology: The Scientific Literature Dominated by Men and a Handful of Countries
Publishing in peer-reviewed scientific journals is crucial for the development of a researcher's career. The scientists that publish the most often in the most prestigious journals generally acquire greater renown, as well as higher responsibilities. However, a team involving two CNRS researchers 1 has just shown that the vast majority of scientific articles in the fields of ecology and conservation biology are authored by men working in a few Western countries.

J oin t Paper Presented at ISSCC 2021 Shows How New Adaptive Back-Biasing Technique O vercomes Integration Limits in Chip Design Flows CEA-Leti & Dolphin Design Report FD-SOI Breakthrough that Boosts Operating Frequency by 450% and Reduces Power Consumption by 30% GRENOBLE, France - Feb. CEA-Leti and Dolphin Design have developed an adaptive back-biasing (ABB) architecture for FD-SOI chips that can be seamlessly integrated in the digital design flow with industrial-grade qualification, overcoming integration drawbacks of existing ABB techniques.
The Mars2020 Mission - Perseverance Rover Landing
Follow along live as the Perseverance rover lands on Mars, thanks to the SuperCam instrument on board which was co-developed by three research laboratories under the supervision of Sorbonne University. On Thursday, February 18, 2021, a little before 10:00 pm, the Perseverance rover will descend on Mars at more than 21,000 km/h.

What if more inclusive urban planning for poor populations was key to fighting dengue fever? This is what researchers from the CNRS, the Institut Pasteur and the Indian Council of Medical Research 1 have demonstrated using a geographical approach applied to the greater city of Delhi (India). Their study is published in the journal PLOS Neglected Tropical Disease on 11 February 2021.
A + A Almost 90 years after its discovery, a large shell from the ornate Marsoulas Cave in the Pyrenees has been studied by a multidisciplinary team from the CNRS, the Muséum de Toulouse, the Université Toulouse - Jean Jaurès and the Musée du quai Branly - Jacques-Chirac 1 : it is believed to be the oldest wind instrument of its type.
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.

GRENOBLE, France - Feb. 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.
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.
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 Breakthrough High-Performance Gyroscope For Automotive, Aeronautic and Industrial Applications
World's First NEMS-Based Gyroscope Operates at 50 kHz, "Beyond Frequencies Of Vibrations Common" in Severe Environments GRENOBLE, France - Jan. CEA-Leti scientists, working with researchers at Politecnico di Milano, have developed the world's first high-performance gyroscope for operating in severe environments, such as industrial and aeronautic equipment and automobiles.

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. 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.

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.
