Astrochemistry, inside cosmic kitchens
Astrochemistry, a relatively new field, focuses on exploring chemistry in interstellar spaces to uncover insights about the origins of life on Earth. This discipline has seen significant advancements in recent years. Born in the late 1930s with the development of spectroscopy and radio astronomy, astrochemistry, a field at the intersection of astrophysics and chemistry, is now mature.

How is an ionic liquid structured when it comes into contact with a wall?
Publication of the Physics Laboratory and Chemistry Laboratory in the journal Langmuir on November 16, 2023. News by CNRS Chemistry on December 19, 2023. Water flowing over soluble rocks can create patterns of multiple troughs bordered by sharp ridges. By combining field measurements, a numerical model and laboratory experiments, a team led by the MSC laboratory (CNRS/Université Paris Cité), in collaboration with the LPG (CNRS/Nantes Université/Université d'Angers) and the RDP (CNRS/ENS de Lyon/Inrae) has shown that the appearance of these shapes results from a geometric mechanism.

A new, more abundant catalyst to generate dihydrogen from water
Publication of the Chemistry Laboratory in the journal ACS Catalysis on November 9, 2023. Communication of CNRS Chemistry on November 27, 2023. Producing dihydrogen by electrolysis of water requires rare and therefore expensive catalysts. They could be replaced by another molybdenum-based catalyst, much more abundant but currently less efficient.

A neural organoid with an immune environment
French, Singaporean and British researchers, led by Prof. Florent Ginhoux, head of a research team at Gustave Roussy/Inserm, have succeeded in demonstrating in a neuronal organoid the role of the brain's immune environment in its formation and development. The development of these three-dimensional structures integrating neuronal cells and the immune environment is, to date, one of the most complete in vitro models of the human brain.

How humans stole the color red from plants
Between 13,000 and 9,650 years ago, the Natoufian culture developed on the eastern Mediterranean coast of northern Israel. According to recent discoveries, these hunter-gatherers were the first to use red pigments of organic origin. "It was a great surprise to discover such ancient and well-preserved pigments of organic origin" , confides Laurent Davin, archaeologist at the Laboratoire Technologie et ethnologie des mondes préhistoriques (Temps) 1 and the Hebrew University of Jerusalem, and co-author of the study just published in the journal PLOS ONE.

Mona Lisa catches the eye of chemists
The mystery of the Mona Lisa lies not so much in her smile as in the painting techniques used by Leonardo da Vinci. Artist, engineer and architect, da Vinci was also an experimental chemist, with the Mona Lisa being his veritable laboratory.

Secrets of Egyptian painters revealed by chemistry
Contrary to prior assumptions, ancient Egyptian painters did at times push the boundaries of convention. Artistic creations supposed to be copies of canonical images were in fact often adapted and reworked during their execution. This discovery was made using new, portable chemical imaging tools that leave the artworks intact.

Malaria: New molecule with therapeutic potential
For the first time ever, a molecule able to prevent the invasion of blood cells by parasites of the genus Plasmodium , responsible for malaria, has been identified and described by CNRS scientists, * in collaboration with American and English colleagues. Their findings, which have just been published in Nature Communications, confirm the key role that myosin A-the 'molecular motor' of Plasmodium -plays in their infiltration of human hosts and penetration of their red blood cells, which triggers malarial attacks.

New molecule to target and eradicate cancer cells with light
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.

Inflammation and cancer: identifying the role of copper paves the way for new therapeutic applications
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.
