With Ultimate Goal of Improving Virus Knowledge, Team Now Will Use its Optomechanical System to Design a Prototype for Airborne Virus Analysis GRENOBLE, France - Oct. 13, 2020 - Targeting analysis of biological particles with large aspect ratios, such as viruses or fibrils, CEA scientists have demonstrated a breakthrough in single-particle mass spectrometry (MS) that could fast track the detection of viral particles in hospitals, offices, airplanes and other public places.
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.
The Earth is the only planet known to have liquid water on its surface, a fundamental characteristic when it comes to explaining the emergence of life.
Since the late 1990s, immunotherapy has been the frontline treatment against lymphomas where synthetic antibodies are used to stop the proliferation of cancerous white blood cells. However, in the more than 20 years since their use began, the molecular mechanisms that underlie this therapy are still little understood.
New Juno results suggest that the violent thunderstorms taking place in Jupiter's atmosphere may form ammonia-rich hail, or 'mushballs', that play a key role in the planet's atmospheric dynamics. This theory, developed using data from Juno's microwave radiometer by the Juno team, is described in two publications led by a researcher at the Laboratoire Lagrange (CNRS/Observatoire de la Côte d'Azur/Université Côte d'Azur) with support from the CNES.
Researchers at the Institut Curie have recently shown that cancer cells use a membrane protein that has been known for several decades to internalise iron. Published (August 3rd, 2020), this work shows that the absorbed iron allows cancer cells to acquire metastatic properties. Biologists knew CD44 well, but didn't know the major biological function that it fulfils.
A team of 76 seismologists, including several French scientists from the CNRS, the Paris Institute of Earth Physics (IPGP), Université de Paris, Université de Strasbourg and the French National Research Institute for Sustainable Development (IRD) 1 discovered that the lockdown measures used in the fight against the spread of COVID-19 have led to a 50% reduction in seismic noise due to human activity across the globe between January-June 2020.
The growth of global livestock farming is a threat to our biodiversity and also increases the health risks to both humans and domesticated animals. The patterns that link them are at the heart of a study published in Biological Conservation by a scientist from the Institute of Evolution Sciences of Montpellier (ISEM - CNRS/Université de Montpellier/IRD/EPHE) and the French Agricultural Research Centre for International Development's (CIRAD) ASTRE laboratory.
Seasonal fluctuations drive the dynamics of many infectious diseases. For instance, the flu spreads more readily in winter. Two scientists from the University of Nantes 1 and the CNRS 2 in Montpellier have developed a mathematical model to predict the risk of the emergence of an epidemic, depending on the time of the year at which the pathogen is introduced.
Scientists from the Coordination Chemistry Laboratory and Laboratory for Analysis and Architecture of Systems, both of the CNRS, recently developed molecular films that can measure the operating temperature of electronic components on a nanometric scale. These patented temperature-sensitive molecules have the distinctive quality of being extremely stable, even after millions of uses.
Flies are able to right themselves very quickly when taking off from an upside-down position. Scientists from the CNRS and from The Institute of Movement Science (ISM) at Aix-Marseille Université studying this phenomenon discovered the surprising way these insects begin by turning their bodies before their heads on take-off.
What makes ships mysteriously slow down or even stop as they travel, even though their engines are working properly? This was first observed in 1893 and was described experimentally in 1904 without all the secrets of this "dead water" being understood. An interdisciplinary team from the CNRS and the University of Poitiers has explained this phenomenon for the first time: the speed changes in ships trapped in dead water are due to waves that act like an undulating conveyor belt on which the boats move back and forth.
Several interacting exoplanets have already been spotted by satellites. But a new breakthrough has been achieved with, for the first time, the detection directly from the ground of an extrasolar system of this type. An international collaboration including CNRS researchers 1 has discovered an unusual planetary system, dubbed WASP-148, using the French instrument SOPHIE at the Observatoire de Haute-Provence (CNRS/Aix-Marseille Université) .
VLSI 2020 Paper Details First Proof of Integration of FDSOI CMOS Devices Processed at 500°C, for Further 3D Monolithic Integration GRENOBLE, France - June 22, 2020 - In an FDSOI CMOS processing breakthrough, CEA-Leti scientists have pushed fabrication thermal-process boundaries down to 500°C for CMOS integration, while showing strong performance gains especially in P-type metal-oxide-semiconductor (PMOS) logic devices.
An international collaboration bringing together over 200 scientists from 13 countries has shown that the very high-energy gamma-ray emission from quasars, galaxies with a highly energetic nucleus, is not concentrated in the region close to their central black hole but in fact extends over several thousand light-years along jets of plasma.
CEA-Leti Demonstrates Breakthrough Architecture for HPC Devices Using Gate-All-Around Nanosheet Fabrication Process
Virtual Presentation During VLSI 2020 Details Transistors' Performance And Power-Use Advantages Versus FinFET Devices -GRENOBLE, France - June 15, 2020 - CEA-Leti has demonstrated fabrication of a new gate-all-around (GAA) nanosheet device as an alternative to FinFET technology targeting high-performance (HPC) applications such as smartphones, laptops, and mobile systems with data collection and processing involving low-power and high-speed operation.

In conventional ultrasounds, variations in soft tissue structure distort ultrasound wavefronts. They blur the image and can hence prove detrimental to medical diagnosis. Researchers at the Institut Langevin (CNRS/ESPCI Paris-PSL) 1 have developed a new non-invasive ultrasound method that avoids such aberrations.
Data-Transmission Rate of 7.7 Gbps Positions LiFi as Possible Replacement for WiFi with Further R&D and Industrial Standardization to Ensure Interoperability of Systems capability of 5G. GRENOBLE, France - June 11, 2020 CEA-Leti today announced its researchers have broken the throughput world record of 5.1 Gbps in visible light communications (VLC) using a single GaN blue microlight-emitting diode (LED).
Tuberculosis: discovery of an ancestral lineage in the African Great Lakes region
Two exceptional strains of tuberculosis, isolated from East African patients with multi-resistant forms of the disease, have been discovered thanks to the use of a new molecular test, Deeplex-MycTB 1. These strains belong to a so far unknown bacterial lineage, apparently limited to the African Great Lakes region.

In contrast to the prehistoric remains of the Near East, the megalithic monuments of Arabia remain largely unknown. These monumental structures, made of dry stone walls, still hold many secrets in terms of their construction, function and chronology. An international collaboration 1 of scientists from France, Saudi Arabia and Italy 2 , led by Olivia Munoz, a researcher at the CNRS, have discovered a 35-metre long triangular platform in the oasis of Dûmat al-Jandal (northern Saudi Arabia).
