Secrets of Egyptian painters revealed by chemistry
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
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
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.

What is the best recipe for making soap bubbles?
What is the best recipe for making soap bubbles?
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.

A technology that 'sees' inside commercial batteries
A technology that ’sees’ inside commercial batteries
Controlling and studying the chemistry of batteries is crucial to improving their design. Scientists have developed an optical fibre based method for monitoring the evolving chemistry of a commercial battery in real time during charging and discharging. These results pave the way for easier and improved battery design.

Plastics response to extreme stretching
By coupling a tensile machine and an in situ dielectric measurement, physicists from Lyon (ENS de Lyon Physicis Laboratory and MATEIS) have made a breakthrough in understanding the molecular reorganizations that allow a polymer film to stretch. The results of this study are published in the journal Macromolecules .

How can digital data stored as DNA be manipulated?
Data can be encoded as DNA but are difficult to process thereafter. A new method enables operations to be performed on DNA-encoded data directly, without having to first translate them into their electronic equivalent. DNA can be used to reliably store a vast amount of digital data. However, retrieval or manipulation of specific data encoded in these molecules has hitherto been difficult.

Ensuring pollen survival: When putting on your coat becomes a collaborative activity
Publication of the RDP in the journal PNAS on May 24, 2022. CNRS-INSB communication on May 30, 2022. Pollen viability depends on a tough external barrier called the pollen wall. Pollen wall components are produced by tapetum cells, which surround developing pollen grains within the anther. Precise coordination of tapetum activity with pollen grain development is required to ensure effective pollen wall formation.

Structural and molecular basis of cross-seeding barriers in amyloids
Publication of CRMN in the journal PNAS on January 5, 2021. Neurodegenerative disorders are frequently associated with -sheet-rich amyloid deposits. Amyloid-forming proteins can aggregate under different structural conformations known as strains, which can exhibit a prion-like behavior and distinct pathophenotypes.

Many Sunscreens Contain a Carcinogenic Compound
An organic sunscreen filter frequently used in sunscreens and anti-aging creams, octocrylene degrades within the bottles themselves into a known carcinogenic and endocrine disrupting compound: benzophenone. This is the result of a groundbreaking study conducted by researchers from the Laboratory of Biodiversity and Microbial Biotechnology of the Oceanological Observatory of Banyuls-sur-Mer (Sorbonne University/CNRS) in collaboration with their American colleagues, published in the journal Chemical Research in Toxicology on March 8, 2021.

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.

The behaviour of therapeutic antibodies in immunotherapy
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.
