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.

Wildflowers increasingly doing without insect pollinators
Wildflowers increasingly doing without insect pollinators
Scientists at the CNRS and the University of Montpellier 1 have discovered that flowering plants growing in farmland are increasingly doing without insect pollinators. As reproduction becomes more difficult for them in an environment depleted in pollinating insects, the plants are evolving towards self-fertilisation.

Leading causes of death in France in 2021
Inserm's Centre d'épidémiologie des causes médicales de décès (CépiDc-Inserm), the Direction de la recherche, des études et de l'évaluation des statistiques (DREES) and Santé Publique France are analyzing the medical causes of death of people living and dying in France in 2021. Two complementary studies, which present these results, are published jointly in études et Résultats (DREES) and in the Bulletin épidémiologique hebdomadaire (Santé publique France).

Set of bacterial genes essential for colonising plant roots
Like humans and animals, plants have a microbiota that shapes their health and thanks to which they assimilate nutrients from the soil. How is this microbiota assembled? Using an innovative approach, scientists at the Max Planck Institute and INRAE have discovered three genes essential for bacteria to colonise plants and live in and on plant roots.

Eating meals early could reduce cardiovascular risk
Freepik A study led by scientists from INRAE, the Barcelona Institute for Global Health, Inserm, and the Université Sorbonne Paris Nord, has revealed that the time at which we eat could influence our risk of developing cardiovascular disease. This study, carried out on a sample of over 100,000 people from the NutriNet-Santé cohort, followed between 2009 and 2022, suggests that eating a late first or last meal is associated with a higher risk of cardiovascular disease.

A new study sheds light on the link between childhood ADHD symptoms and physical health conditions
Attention-deficit hyperactivity disorder (ADHD) affects many children and is often accompanied by other conditions, such as metabolic disorders, asthma and dental caries. However, uncertainties remain as to the chronology of onset of such conditions, particularly when it comes to knowing which are linked with ADHD over time or, on the other hand, which increase the risk of developing ADHD symptoms.

Discovery of the role of a brain regulator involved in psychiatric illnesses
Contrary to all expectations, GluD1 - a receptor considered to be excitatory - has been shown in the brain to play a major role in controlling neuron inhibition. Given that alterations in the GluD1 gene are encountered in a certain number of neurodevelopmental and psychiatric disorders, such as autism (ASD) and schizophrenia, this discovery opens up new therapeutic avenues to combat the imbalances between excitatory and inhibitory neurotransmissions associated with these disorders.

First 3D mapping in the embryo
Improving our knowledge of the development of the complex structures that make up the human head, and thus gaining a better understanding of the congenital anomalies that cause malformations: this is the challenge that a team of researchers from Inserm, CNRS and Sorbonne Université at the Institut de la vision, Université Claude Bernard Lyon 1 and Hospices civils de Lyon is well on the way to meeting.

The ocean may be storing more carbon than estimated in earlier studies
The ocean may be storing more carbon than estimated in earlier studies
The ocean's capacity to store atmospheric carbon dioxide is some 20% greater than the estimates contained in the latest IPCC report 1 . These are the findings of a study to be published in the journal Nature on December 6, 2023, led by an international team including a biologist from the CNRS 2 . The scientists looked at the role played by plankton in the natural transport of carbon from surface waters down to the seabed.

Stellar winds regulate growth of galaxies
Stellar winds regulate growth of galaxies
Galactic winds enable the exchange of matter between galaxies and their surroundings. In this way, they limit the growth of galaxies, that is, their star formation rate. Although this had already been observed in the local universe, an international research team led by a CNRS scientist 1   has just revealed-using MUSE, 2  an instrument integrated into the European Southern Observatory's (ESO) Very Large Telescope-the existence of the phenomenon in galaxies which are more than 7 billion years old and actively forming stars, the category to which most galaxies belong.

An international collaboration identifies new genes influencing beef production
Beef currently accounts for 21% of the world's meat consumption, placing it third after poultry and pork. It therefore plays a crucial role in the global food system, with great economic and cultural importance in many countries. However, its production has a high environmental impact, mainly due to greenhouse gas emissions that contribute to climate change.

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.
