The liver may influence the body's central biological clock, a group of brain cells that influence most physiological and behavioral aspects. Our liver partly controls our central biological clock, according to scientists from CNRS and Université Paris Cité. Their study, to be published on May 17, 2023 in the journal Science Advances, has indeed shown that it was possible to shift the biological clock of mice by introducing human liver cells into their liver.

Scientists have designed a molecule that can accumulate in cancer cells specifically and become toxic upon exposure to light. Scientists from the CNRS, ENS de Lyon, University of Angers, and Claude Bernard Lyon 1 University, in collaboration with colleagues from Swedish and South Korean institutions, have developed a new molecule that selectively accumulates in cancer cells and, after exposure to light, turns toxic.

  Bird populations across continental Europe have declined by 25% in 40 years, with this figure reaching nearly 60% for species found in agricultural environments. Intensive farming is the main source of pressure linked to declining bird populations. These findings come from the largest and most comprehensive bird study to date in Europe.

Young stars are surrounded by disks of material where future planets are born. The James Webb telescope has revealed the chemical composition of the disk of the star J160532, rich in hydrocarbons. Observations in recent years have shown that rocky exoplanets are very abundant around "light" stars like J160532.

  Young stars are surrounded by discs of material from which future planets form. The James Webb Space Telescope has revealed the chemical composition of the disc around the star J160532, which turns out to be rich in hydrocarbons. In recent years, observations  have shown that rocky exoplanets are very abundant around low-mass stars such as J160532.

In major metropolises, drivers looking for parking often represent more than 10% of urban traffic 1 , making both pollution and frustration worse! Can physics help understand the headache of parking in cities? Yes, if we are to believe the research conducted by a team led by a CNRS researcher at the Institute of Light and Matter (CNRS/Université Claude Bernard Lyon 1), which has proposed a new approach to the topic.

  By combining various techniques, scientists have successfully revealed the internal structure of the Moon. Their findings confirm that the Moon has a solid core, like the Earth. They also confirm the 'mantle overturn' and explain the presence of iron-rich elements at the surface of the Moon.

A team from the CEA and CNRS have discovered the existence of mirusviruses: a major group of viruses abundant on the surface of the seas and oceans, where they infect single-celled plankton. These findings appear in Nature on 19 April. The discovery provides a better understanding of the scope of ocean biodiversity and the importance of viruses in these ecosystems.

Extreme heatwaves are rare, but they have major consequences on living beings and their environments. Anticipating their arrival is a central challenge. In an article published in Physical Review Fluids on April 4th, an interdisciplinary team of French scientists 1 from the CNRS, the CEA, and the Claude Bernard University Lyon 1 unveiled artificial intelligence 2 that can predict heatwaves.

Without realising it, our brain continuously processes sounds and infers semantic information, such as the presence of birds in a tree based on hearing their song.

Study of metal components from Notre Dame site. Cyril FRESILLON / IRAMAT / NIMBE / ArScAn / CEA / Chantier Scientifique Notre-Dame de Paris / French Ministry of Culture / CNRS Is Notre Dame the original Iron Lady? Evidence of the earliest known use of the metal for the construction of a Gothic cathedral has been uncovered by a team of scientists 1 working at the Notre Dame research site (CNRS / French Ministry of Culture).

1 While insulin-like growth factor 1 (IGF-1), mainly produced by the liver, has a chemical structure similar to that of insulin, these hormones have distinct functions: IGF-1 stimulates tissue and skeletal growth, whereas insulin regulates energy metabolism as required for growth. The gut microbiota is now thought to constitute an organ in its own right.

The North Alfeo Fault runs across the seafloor at the base of Mount Etna, the tallest and currently most active European volcano, next to an urban area with a population of one million. The Focus project seeks to better understand seismic processes in action and allow for surveillance of movement along the fault.

Humans are not the only ones to teach their children good hygiene practices - mandrills do it too. In these primates, where many individuals are infected with contagious gastrointestinal parasites, some females systematically avoid grooming the peri-anal region of their groupmates.

What mechanisms are behind the formation of flowers? To answer this question a 25-year-old enigma has just been solved: the role of UFO protein in the flower's formation process. While its nature suggested that it destroys its partners, this protein is in fact an aid to the birth of a flower when coupled to the LEAFY protein.

According to a study published in The American Naturalist on 6 January 2022, sequences of environmental events over time influence population dynamics in wild species. A research team led by Marlène Gamelon, a researcher at the CNRS 1 , has studied the influence of sequences of oak mast seeding events over the years on a population of wild boars 2 , which are major consumers of acorns.

How will our glaciers change during the 21st century? In a new study whose findings are published in Science (5 January), an international team 1 , including scientists from the CNRS and Université Toulouse III-Paul Sabatier, has demonstrated a loss of glacial mass greater than earlier projected-and specifically, 11% to 44% higher than estimates used in the most recent IPCC report.

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.

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.

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 .
