A novel antibiotic resistance mechanism
A novel antibiotic resistance mechanism
Bacteria make use of a number of natural resistance strategies to overcome antibiotics. And it seems that this bacterial toolbox may be much more varied than previously thought. Scientists at the Institut Pasteur, in collaboration with Inserm, INRA, the CNRS and the Weizmann Institute of Science in Israel, have recently revealed an entirely unknown resistance mechanism in Listeria monocytogenes bacteria.

Silicosis is on the rise, but is there a therapeutic target ?
Paris, 6 December 2018 Researchers from the CNRS, the University of Orléans, and the company Artimmune, in collaboration with Turkish clinicians from Atatürk University, have identified a key mechanism of lung inflammation induced by silica exposure, which leads to silicosis, an incurable disease. Their study in mice and patients, published (December 6th, 2018), shows that this inflammation can be prevented by extracellular DNA degradation, suggesting a new therapeutic target.

A prosthetic arm that decodes phantom limb movements
A prosthetic arm that decodes phantom limb movements
Paris, 29 November 2018 About 75% of amputees exhibit mobility of their phantom limb. Using this information, in collaboration with physicians 1 , researchers from CNRS and Aix-Marseille University have developed a prototype capable of detecting these movements and activating a prosthetic arm. The prosthesis does not require any surgery and patients do not need training.

The origins of asymmetry : A protein that makes you do the twist
The origins of asymmetry : A protein that makes you do the twist
Paris, 22 November 2018 Asymmetry plays a major role in biology at every scale: think of DNA spirals, the fact that the human heart is positioned on the left, our preference to use our left or right hand … A team from the Institute of biology Valrose (CNRS/Inserm/Université Côte d'Azur), in collaboration with colleagues from the University of Pennsylvania, has shown how a single protein induces a spiral motion in another molecule.

Stroke : preventing the damage by acting on the neuronal environment ?
Paris, 15 November 2018 To protect neurons and limit the damage after a stroke, researchers from the CNRS, the University of Caen-Normandie, University Paris-Est Créteil, and the company OTR3 have pursued an innovative path: targeting the matrix that surrounds and supports brain cells. Their results, just published in the journal Theranostics , have confirmed this strategy on rats, and will lead to a clinical study between now and late 2019.

"Nested sequences" : an indispensable mechanism for forming memories
A research team from CNRS, Université PSL, the Collège de France and Inserm has just lifted part of the veil surrounding brain activity during sleep. Though we know that some neurons are reactivated then to consolidate our memories, we did not know how these cells could “remember” which order to turn on in.

Tara back from Pacific expedition with startling data : motley map of reef health
Tara back from Pacific expedition with startling data : motley map of reef health
After two and a half years navigating the Pacific, where over 40% of our planet's coral reefs are found, the schooner Tara returned to Lorient, its home port in Brittany, on October 27. Led by the Tara Expeditions Foundation, the Tara Pacific expedition deserves a round of applause: it has allowed scientists to study the impact of anthropogenic pressures on Pacific coral reefs using a novel approach on an unprecedented scale.

Open science : International data exchange for sharing primate neuroimaging datasets
Open science : International data exchange for sharing primate neuroimaging datasets
The goal of the PRIME-DE1 data exchange is to make primate brain imaging datasets acquired in laboratories available to the entire scientific community. PRIME-DE was created by an international consortium of 22 teams—including six from the CNRS, INSERM, and the CEA—all working with macaques. Because the brains of macaques are organized so similarly to our own, these animals are crucial to the study of human brain function and pathology.

Optical illusion spooks raptors
Optical illusion spooks raptors
Researchers from the CNRS and Université de Rennes 1 1 , in collaboration with Airbus, have designed a visual pattern that elicits long-term avoidance of high-risk areas by raptors. The scientists' work clears the way for further investigation into the visual cognition of these birds, and it has applications for conservation, because raptors are among the most common victims of collisions with planes and wind turbines.

Questioning the link between pollution by magnetite particles and Alzheimer’s disease
A 2016 study 1 showed that exposure to urban pollution involving magnetite particles played a role in the development of Alzheimer's disease. It began from the hypothesis that magnetite particles would generate chemical reactions that could cause oxidative stress for neurons. CNRS researchers have now called this connection into question, showing that it is very unlikely that magnetite is involved in neuron degeneration.
