A soap bubble attracts the attention of young and old. Who has never wondered the recipe of these fascinating bubbles or how to get the biggest one - In collaboration with artists, who have a great empirical knowledge of the recipes that work in their acts, a team from the Laboratory of Solid State Physics (CNRS/University of Paris-Saclay) has identified the main ingredients ensuring to get the best bubbles.
Microfibers of the Mediterranean
A consortium of bacteria form on the microfibers of the Mediterranean Sea, becoming "floating homes for bacteria". Maria Luiza Pedrotti, a CNRS researcher at the Villefranche-sur-Mer oceanography laboratory has reported the presence of a pathogenic bacterium on the tiny textile fibers found in the deep blue sea.

WEAVE has carried out its first-light observations on Stephan's Quintet, a group of five galaxies, some of which are undergoing collision. They provide a demonstration of its exceptional capabilities and hold out the promise of major discoveries. WEAVE, a new spectrograph on the William Herschel Telescope (Canary Islands, Spain), has successfully carried out first-light observations of a group of five galaxies called Stephan's Quintet, thus demonstrating its unprecedented capabilities and providing the astronomical community with the promise of many new discoveries.
COVID-19: a respiratory vaccine effective in mice
Less known to the general public, mucosal vaccination via the mucus membranes could provide robust protection against SARS-CoV-2 infections. Immune cells in the nose and lungs are considered better prepared to encounter and block the virus that causes COVID-19. An international research team has just demonstrated that its mucosal DNA vaccine is capable of ensuring the total survival of a group of mice infected with a version of the virus adapted to this species, whereas the latter kills 100% of unvaccinated mice 1 .

Mapping the chemistry of the Earth’s mantle
Publication of the LGL-TPE in the journal PNAS on November 21, 2022. CNRS-INSU communication on December 7, 2022. In the 1980s, geochemical observations led researchers to propose a geodynamic model of the mantle's marbled structure. A team of scientists, some of whom are attached to the Laboratory of Geology of Lyon: Earth, Planets, Environment (LGL-TPE, CNRS/ENS de Lyon/Claude Bernard Lyon 1 University), has been working on this model using a seismological perspective.

While great progress has been made in recent years in the understanding of autism spectrum disorder (ASD), its underlying molecular mechanisms remain fairly poorly documented.
For the first time in over a decade, scientists from the CNRS and the Institut de radioastronomie millimétrique 1 , together with international colleagues, have observed a tidal disruption event (TDE
Development of a pentavalent vaccine against New World arenaviruses
Publication of the CIRI in the journal Nature Microbiology on January 5, 2023. Communication of the Institut Pasteur on January 6, 2023. A team from the Institut Pasteur, hosted at CIRI, has developed and successfully tested on a primate model a pentavalent vaccine against the five pathogenic arenaviruses circulating in South America.

Tuberculosis affects 1 million children each year; less than half of them are diagnosed and treated for the disease, which leads to more than 200,000 deaths.
Since the beginning of 2022, a study of the archaeology of the building led by the Inrap is engaged on the bell tower and the western facade of the cathedral of Nîmes. It is an exceptional opportunity to deepen our knowledge of this emblematic building of the city of Nîmes, by studying closely its elevations.
How can bats harbor so many viruses without developing symptoms?
Bats are asymptomatic carriers of a multitude of viruses that are pathogenic to most other mammals. How has their immune system evolved to shield them from these pathogens? A team of scientists-the majority affiliated with the CNRS, Claude Bernard Lyon 1 University, and ENS de Lyon 1 - has just published an article in Science Advances addressing that question.

In bocage landscapes, the hedgerows that border cultivated fields provide many services. However, they are often perceived as sources of weeds, those wild plants generally called "weeds" and considered undesirable. Scientists from INRAE, in partnership with teams from the University of Rennes 1, CNRS and ANSES, studied the impacts of bocage landscapes on weeds.
Both sickle cell disease and beta-thalassemia are genetic disorders that affect hemoglobin, and as such are categorized as beta-hemoglobinopathies. A team of scientists from Inserm, Université Paris Cité and the Paris Public Hospitals Group AP-HP at the Imagine Institute has shown the efficacy of a gene therapy approach to treat these two disorders.
An international consortium has identified rare variants in two new genes that markedly increase the risk of developing Alzheimer's disease (AD). The work was led by two research groups in France (headed respectively by Gaël Nicolas, Rouen and Jean-Charles Lambert, Lille) and a group in the Netherlands (headed by Henne Holstege, Amsterdam).
People with liver disease caused by eating too much sugar and fat could be at increased risk of developing serious neurological conditions like depression or dementia. In a study examining the link between non-alcoholic fatty liver disease (NAFLD) and brain dysfunction, scientists at the Roger Williams Institute of Hepatology, affiliated to King's College London and the University of Lausanne, found an accumulation of fat in the liver causes a decrease in oxygen to the brain and inflammation to brain tissue - both of which have been proven to lead to the onset of severe brain diseases.
Cisplatin is a chemotherapy indicated to fight tumors in many types of cancer. However, it does have major side effects - especially kidney toxicity, that can lead to acute kidney failure. In addition, patients treated with cisplatin also often report high levels of neuropathic pain.
How can we navigate airliners or allow military vehicles to stay on course without GPS or satellite signals? This is a problem for which quantum inertial sensors offer a solution. Harnessing quantum technology, they can take ultrasensitive measurements of acceleration in three dimensions, and in any orientation.
Several months after SARS-CoV-2 infection, some patients continue to have symptoms. This phenomenon, known as "post-COVID condition” or, more commonly, "long COVID”, remains poorly documented. In order to address this and improve patient care, research teams are trying to improve their understanding of the underlying biological and immunological mechanisms.
For the first time, a digital model has shown that both fishing and climate-induced environmental change are responsible for the collapse of cod stocks in the North Sea. Taking into consideration these two factors together is crucial for the sustainable management of fish stocks. Using a new digital model, an international team led by researchers from the oceanology and geosciences laboratory (LOG) (CNRS/Université de Lille/Université du Littoral Côte d'Opale) has shown how fishing and climate affect cod stocks in the North Sea.
