The validation and application of theories in physics require the measurement of universal values known as fundamental constants. A team of French researchers 1 has just conducted the most accurate measurement to date of the fine-structure constant, which characterizes the strength of interaction between light and charged elementary particles, such as electrons.

Machine learning: a breakthrough in the study of stellar nurseries
Artificial intelligence can make it possible to see astrophysical phenomena that were previously beyond reach. This has now been demonstrated by scientists from the CNRS, IRAM, Observatoire de Paris-PSL, Ecole Centrale Marseille and Ecole Centrale Lille, working together in the ORION-B 1 programme. In a series of three papers published in Astronomy & Astrophysics on 19 November 2020, they present the most comprehensive observations yet carried out of one of the star-forming regions closest to the Earth.

Greater mosquito susceptibility to Zika virus fueled the epidemic
The Zika virus has spread around the world over the last decade, causing millions of infections, some of which have been associated with congenital abnormalities and neurological disorders. Scientists from the CNRS, the Institut Pasteur, and the IRD 1 turned their attention to the main vector of the virus, the mosquito Aedes aegypti .

How can we estimate the evolution of the reproductive number for Covid-19 in a better way?
A team of interdisciplinary researchers has demonstrated that convex optimization is an effective mathematical and numerical tool for a daily estimate of the evolution of the reproductive number for Covid-19, over time and across regions. Monitoring the spread of the Covid-19 pandemic is one of the major challenges of the global health crisis.

Kolmogorovian Active Turbulence of a Sparse Assembly of Interacting Marangoni Surfers
Publication by Laboratoire de physique in Physical Review X on June 22, 2020. Abstract Active matter, composed of self-propelled entities, forms a wide class of out-of-equilibrium systems that display striking collective behaviors, among which, the so-called active turbulence where spatially and time-disordered flow patterns spontaneously arise in a variety of active systems.

From green to orange, where does the diversity of cyanobacteria colours come from?
From green to orange, where does the diversity of cyanobacteria colours come from?
Cyanobacteria, which are often called blue algae, can actually adopt colours ranging from green to orange via pink, depending on the dominant photosynthetic pigment in the cells of particular species. Not all cyanobacteria, however, capture light in the same way: Prochlorococcus , for example, the most abundant cyanobacterium in the ocean, preferentially absorbs violet and blue wavelengths, while its cousin Synechococcus captures blue, green or both, depending on its pigment type.

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
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.

Surprisingly mature galaxies in the early Universe
Surprisingly mature galaxies in the early Universe
When the Universe was only a tenth of its current age its galaxies experienced a growth spurt.  It was this period that the scientists in the ALPINE project 1 focused on when they used ESO's ALMA 2 telescope to carry out the first ever large survey of distant galaxies.  To their surprise, these galaxies observed in the early stages of their life were far more mature than expected.

Deep magma facilitates the movement of tectonic plates
A small amount of molten rock located under tectonic plates encourages them to move. This is what scientists from the Laboratoire de géologie de Lyon: Terre, planètes et environnement (CNRS/ENS de Lyon/Université Claude Bernard Lyon 1) have recently discovered. Their new model takes into account not only the velocity of seismic waves but also the way in which they are attenuated by the medium they pass through.

High-temperature, low carbon processes: the challenge for the new Canopée laboratory
The CNRS, l'Université de Lorraine and Saint-Gobain Group signed, this Friday, October 23, 2020, the creation of the Canopée laboratory, dedicated to the study of materials and "systems" under extreme temperature conditions. The objective is to reduce the carbon footprint of high-temperature manufacturing processes.

Unexpectedly large number of trees populate the Western Sahara and the Sahel
The number of trees inhabiting the Western Sahara, the Sahel and the Sudanian zone has exceeded the expectations of scientists, with more than 1.8 billion having been located thanks to an international collaboration including researchers from the CNRS 1 . High-resolution remote sensing made it possible to gather a multitude of satellite images of these areas, which were then analysed by applying an artificial intelligence pattern recognition method.

Double jeopardy for ecologically rare birds and terrestrial mammals
Double jeopardy for ecologically rare birds and terrestrial mammals
Common assumptions notwithstanding, rare species can play unique and essential ecological roles.  After studying two databases that together cover all known terrestrial mammals and birds worldwide, scientists from the CNRS, the Foundation for Biodiversity Research (FRB), Université Grenoble Alpes, and the University of Montpellier 1 have demonstrated that, though these species are found on all continents, they are more threatened by human pressures than ecologically common species and will also be more impacted by future climate change.

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.

The behaviour of therapeutic antibodies in immunotherapy
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.

Ammonia-rich hail sheds new light on Jupiter's weather
Ammonia-rich hail sheds new light on Jupiter’s weather
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.

Iron-mediated cancer cell activity: a new regulation mechanism
Iron-mediated cancer cell activity: a new regulation mechanism
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.
