Invasive species: improving the assessment of how they redefine ecosystems

O A page from Archimedes' palimpsest, considered lost for several decades, has been identified by a CNRS researcher at the Musée des Beaux-Arts in Blois.

Tanycytes (white) capture Tau protein (red) circulating in the cerebrospinal fluid and transport it along their extensions/arms, which pass through brain tissue and come into contact with blood vessels (green), into which they release this protein, which is involved in Alzheimer's disease when it accumulates in the brain.

Sleep apnea affects nearly one billion people worldwide and causes repeated episodes of oxygen deprivation during the night, known as intermittent hypoxia.

In Paris, districts with more vegetation have a lower risk of death during periods of high heat, while highly mineralized areas with few green spaces and a high potential for urban heat islands are the most exposed.

In the event of neuroinflammation, the brain has a rapid defense mechanism: tiny bone channels allow immune cells to pass directly from the cranial bone to the meninges.

A research team led by a CNRS 1 researcher has for the first time accurately determined the age of the cave paintings at Font-de-Gaume (Les Eyzies) in Dordogne (southwestern France), according to work to be published on 9 March 2026 in PNAS.

According to a CNRS communication dated February 19, 2026. Based on a scientific publication in Science Advances , to which the RDP - Plant Reproduction and Development Laboratory contributed: "The actin cytoskeleton is required to maintain plant cell division orientation against cellular geometry."

In plants, cells can neither move nor reorganize freely due to their rigid walls. How, then, do they correctly orient their division to build coherent tissues - A study published in Science Advances reveals that, in addition to an already well-documented classical cue, plant cells rely on the actin cytoskeleton to adjust the plane of division according to their environment.

Hypertension and diabetes are often associated, greatly increasing the risk of stroke and severe kidney damage.
