In 2020, in the midst of the COVID-19 crisis, we spoke with Franck Zal, a doctor in marine biology from Sorbonne University and founder of the company Hemarina. At the time, HEMO2life - their flagship product created from the hemoglobin of the marine worm, the arenicole - was envisaged to improve the oxygenation of patients suffering from acute respiratory distress syndrome.
The liver could influence the body's central biological clock, a group of brain cells that influence most aspects of physiology and behaviour. Our liver plays a role in regulating our central biological clock, scientists from CNRS and Université Paris have discovered. The results of their study, published on 17 May in Science Advances, show that the biological clock of mice can be reprogrammed by inserting human liver cells into the animal's liver.
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.
James Webb Space Telescope reveals composition of protoplanetary disc
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.

The James Webb Telescope reveals the composition of a protoplanetary disk
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.

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.
In a recent study published in the journal Nature Medicine , a research team from Université Paris Cité, Inserm and AP-HP, led by Professor Alexandre Loupy at the Centre d'expertise de la transplantation multi-organ de Paris, has created an automated computer assistant that can correct 40% of misdiagnoses of allograft rejection in humans and better guide patient management .
In France, one third of emergency room visits are due to trauma. In order to better understand their mechanisms and improve their management, researchers from Inserm and the University of Bordeaux at the Bordeaux Population Health research center, together with teams from the Bordeaux University Hospital, have developed an algorithm capable of classifying emergency room visits due to trauma by analyzing clinical reports through artificial intelligence (GPT).
Long COVID: The Persistence of SARS-CoV-2 in the Mucous Membranes May Be A Factor
This transmission electron microscope image shows SARS-CoV-2, isolated from a patient in the U.S., emerging from the surface of cells cultivated in a laboratory. National Institute of Allergy and Infectious Diseases-Rocky Mountain Laboratories, NIH. Public domain. Several months after infection with SARS-CoV-2, some patients still have symptoms: a phenomenon commonly referred to as "long COVID”.

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.
For the first time, researchers from Institut Curie, the CNRS and Inserm have uncovered a previously unknown chain of biochemical reactions. This chain involves copper and leads to metabolic and epigenetic alterations that activate inflammation and tumorigenesis. But there is more; the research team developed a "drug prototype" capable of mitigating both the mechanisms of inflammation and the processes potentially involved in metastatic spread.
Hypertension: A Mixture of Air Pollutants Could Cause Repeated High Blood Pressure Peaks
Air pollution is an acknowledged environmental factor in high blood pressure. It consists of a mixture of particles and gases whose combined effects on human health are not yet well known. A team from Inserm and Sorbonne Université, assisted by international collaborators, used continuous monitoring to study the daily life impact of a mixture of five air pollutants on the blood pressure of 221 MobiliSense study participants in the Greater Paris area.

Nanosciences: new pieces to the jigsaw puzzle of nanothermodynamics
Publication of the Chemistry Laboratory in the journal Nature Comunication on April 1st, 2023. Communication of the CNRS-INC on April 20, 2023. Historically developed for macroscopic systems, thermodynamics is the science that allows to precisely define pressure and temperature by focusing on a system's energy flows.

Gels’ ’memory’ guides their mechanical properties
Publication of the Physics Laboratory in the journal Nature Physics on May 4, 2023. Communication of the CNRS-INSIS on May 9, 2023. The more solids a gel contains, the more solid it is. However, this principle is not sufficient to explain all the mechanical behaviors observed in reality. An international team has discovered that the macroscopic mechanical properties of gels are due to heterogeneities in their structure, inherited from the singular microstructure that the material adopts at the very moment of its gelation.

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.
