In a constantly changing world, making good decisions requires the ability to explore different strategies and to identify the one that will be the most appropriate. Research conducted by a team of neuroscientists from Inserm and CNRS at the École Normale Supérieure - PSL, in collaboration with Harvard University (USA), has made it possible to characterize this cognitive process by recording the tiny changes in the magnetic field emitted by the activity of the human brain.
The James Webb telescope has delivered extraordinary new images of the Orion Nebula. Many stars are born in this nebula, hence these observations could yield information on the origins of our Solar system. The new images were obtained by a team headed by French and Canadian researchers. An international research team has released the first images of the Orion Nebula, the closest richly productive stellar nursery to our own solar system.
The donkey has shaped the history of humankind, both as a source of power for farm work, and of transportation in sometimes hard to reach areas. To understand the history of the donkey's domestication, teams at the Centre for Anthropobiology and Genomics of Toulouse (CNRS/ Université Toulouse 3 Paul Sabatier) and scientists 1 from 37 laboratories around the world worked together to build and analyse the most complete panel of genomes ever studied for this animal.
COVID-19: Keys to the disease in the past of primate and bat genes?
Publication of the CIRI in the journal PNAS . CNRS-INSB communication on September 7, 2022. The coronavirus disease 19 (COVID-19) pandemic is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a coronavirus that spilled over from the bat reservoir. Despite numerous clinical trials and vaccines, the burden remains immense, and the host determinants of SARS-CoV-2 susceptibility and COVID-19 severity remain largely unknown.

Cardiovascular diseases are the leading cause of death worldwide. Identifying the risk factors associated with these diseases in order to better prevent them represents a real public health challenge. A group of researchers from Inserm, INRAE, Cnam and Université Sorbonne Paris Nord within the Nutritional epidemiology research team (Eren) studied the health impacts of artificial sweetener consumption.
Preeclampsia is a condition that affects the placenta during pregnancy and is dangerous for both the fetus and the mother. Scientists from the Institut Pasteur, Inserm and the CNRS have proposed a new therapy, tested in two rodent models, that corrects the defects identified in placental cells, and restores placental and fetal weight.
On February 21, 2021, NASA's Perseverance rover landed in the Jezero Crater on Mars. In October 1 , the rover confirmed the importance of its landing site, showing that Jezero Crater really was the site of a lake 3.6 billion years ago. Perseverance's geological discoveries in the crater's floor are described in four papers published on August 25, 2022 in Science and Science Advances .
Temperature and mortality are linked. There is a short-term increase in mortality when temperatures are at their hottest or coldest - a phenomenon known as a "U-shaped relationship”.
Sahelanthropus, the oldest representative of humanity, was indeed bipedal...but that’s not all!
The modalities and date of emergence of bipedalism remain bitterly debated, in particular because of a small number of very old human fossils. Sahelanthropus tchadensis , discovered in 2001 in Chad, is considered to be the oldest representative of the humankind. The shape of its cranium suggests a bipedal station.

Until now, it has been assumed that the oxygenation of the oceans over geological timescales has mainly been driven by atmospheric oxygen levels. However, a new study published in Nature June 27 2022 suggests otherwise. Work by scientists at the Biogeosciences Laboratory (CNRS/UBFC), together with their colleagues at the University of California's Department of Earth and Planetary Sciences, shows that the movement of tectonic plates has probably contributed to ocean oxygenation.
Ultrasound is transforming the field of neuroimaging, thanks to technological advances made over the last decade by the Physics for Medicine laboratory (Inserm, ESPCI Paris - PSL, CNRS). The introduction of functional ultrasound imaging (fUS) in 2009 provided neuroscientists with a unique technology - portable, easy to use, and reasonably priced - to visualize brain activity with high sensitivity.
Chromosomes are fluid - almost liquid - outside their division phases. This discovery was made possible thanks to the direct mechanical manipulation, for the very first time, of chromosomes in the nucleus of living cells. Until then, chromosomes - which are very long DNA molecules - were represented as being entangled like loose balls of yarn, and forming a sort of gel.
Research INSTITUT-IphU A Long Time Ago, in a Galaxy Far, Far Away... with JWST
The James Webb Space Telescope (JWST) is the successor of the Hubble Space Telescope. JWST is designed to answer outstanding questions about our origins: from the formation of stars and planets to the birth of the first galaxies in the early Universe. JWST was built by an international partnership between NASA, ESA, and CSA.

Constructing a tiny robot from DNA and using it to study cell processes invisible to the naked eye. You would be forgiven for thinking it is science fiction, but it is in fact the subject of serious research by scientists from Inserm, CNRS and Université de Montpellier at the Structural Biology Center in Montpellier .
Neurons communicate with each other across synapses, areas of close contact where neurotransmitter molecules released from one neuron act on receptors embedded in the membrane of the opposite neuron. Previous research conducted by the team of Daniel Choquet, researcher at the CNRS and Director of the Interdisciplinary Institute for Neurosciences (CNRS/University of Bordeaux) had discovered that these receptors are not stationary, but instead move constantly in the membrane.
Pain Intensity Is Controlled by Our Internal Clock
As with many of the body's functions, pain intensity is controlled by our internal clock. This is what a team of Inserm researchers at the Lyon Neuroscience Research Center (Inserm/Université Claude Bernard Lyon 1/CNRS) has recently discovered. They show that pain oscillates over 24 hours with a peak at night and a decrease in the afternoon, regardless of the sleep-wake cycle or any external stimulation.

Human interactions are enabled by a set of neurocognitive mechanisms defined by the notion of social cognition. In order to detect patients with social cognition disorders, specialists use internationally validated evaluation tests. However, most of these tests have been developed in industrialized Western countries, which raises questions about the relevance of generalizing them to the whole of humanity.

This study by scientists at the Institut des sciences du mouvement Etienne-Jules Marey (CNRS/Aix-Marseille Université) reveals students' psychological distress during COVID-19-related lockdown and distance learning, as well as the effectiveness of an online mindfulness meditation practice in countering it.
Type 2 diabetes is a major public health problem that affects millions of people worldwide. Developing new drugs to help better treat its underlying causes is therefore a research priority. In a new study coordinated by Inserm researcher Vincent Marion in collaboration with the University of Birmingham (UK), Monash University (Australia), and along with Alexander Fleming, former senior endocrinologist the US Food and Drug Administration (FDA), the scientists have developed PATAS, a peptide that is part of a new class of antidiabetic drugs.
