One of the crucial stages of gestation is implantation of the embryo in the uterus, in contact with a tissue called the endometrium. However, the mechanisms that enable this implantation remain largely unclear. A Franco-American collaboration co-led by INRA research scientists has revealed that intense and fine-tuned crosstalk is established between the embryo and endometrium, allowing them to adapt to each other.
An international research team that included INRA and CNRS scientists has revealed the key role played by rare plant species in maintaining ecosystem "multifunctionality": both species and evolutionary diversity is important. This work was recently been published in PNAS . Based on data from 123 sampling sites around the world, the results show that taxonomic, functional, and phylogenetic biodiversity matters for ecosystem functioning.
INRA, CIRAD, and CNRS researchers recently made an unprecedented discovery: the different genomic segments of a multipartite 1 virus can occupy distinct cells within their host but still work together to generate infection. This finding challenges a key paradigm in virology, notably that a virus's entire genome must enter a given cell and replicate therein before repeating the process in subsequent cells, thus causing infection.
Researchers from INRA, CIRAD, CEA, the University of Montpellier, and Chicago and Vanderbilt Universities in the United States have developed an innovative method for analysing the genome of the Wolbachia bacterium. This endosymbiotic* bacterium infects more than 70% of insects and is capable of influencing insect transmission of pathogens such as dengue or Zika virus.
Grown throughout the world, F1 hybrid crop varieties have highly desirable traits. However, they remain expensive to produce. This situation may be about to change. By modifying the expression of certain genes, INRA researchers have created hybrid rice plants whose seeds give rise to offspring that are identical to the mother plant.
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.
Paris, 9 January 2017 To paint quickly while creating exceptional texture and volume effects, J. M. W. Turner and other English artists of his generation relied on the development of innovative gels. All the rage in the 19th century—and still in use today—these compounds alter the properties of the oil paints they are combined with.
PARIS, 17 december 2018 Researchers at CNRS, Université Côte d'Azur and Inserm have demonstrated a new mechanism related to the onset of migraine. In fact, they found how a mutation, causes dysfunction in a protein which inhibits neuronal electrical activity, induces migraines. These results, published in Neuron on December 17, 2018, open a new path for the development of anti-migraine medicines.
A study conducted by the University Hospital of Besançon and INRA shows the protective effect of high cheese consumption from a very young age. For the first time, a link has been established between cheese consumption and the probability of developing food or skin allergic diseases, regardless of the consumption of various other foods (vegetables or fruits, cereals, bread, meat, cake and yogurt) and living conditions in a farm environment (presence and diversity of farm animals).

A diet based on MON 810 or NK603 transgenic maize does not affect the health or metabolism of rats, under the conditions of the GMO 90+1 project 1 . This unprecedented study performed by a research consortium led by Inra brought together a number of partners 2 , including Inserm. For six months, rats were fed a diet containing either GM maize (MON 810 or NK603) or non-GM maize, in varying concentrations.
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.
Paris, December 5, 2018 Researchers from the CNRS 1 and the Université Libre de Bruxelles (ULB) have prepared the first global map of the distribution of atmospheric ammonia (NH3) by analyzing measurements taken by satellites between 2008 and 2016. The IASI interferometer developed by the CNES allowed them to catalog more than 200 ammonia sources, two-thirds of which had never been identified before.
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.
Paris, 29 November 2018 Scientists have revealed, for the first time outside our Galaxy, the properties of rapidly moving gas clouds in the immediate vicinity of a super-massive black hole, enabling the mass of the black hole to be measured with unprecedented accuracy.
Paris, November 29, 2018 Researchers from the CNRS and université Toulouse III – Paul Sabatier (UT3) show that fruit flies possess all of the cognitive capacities needed to culturally transmit their sexual preferences across generations. The study, published on November 30, 2018 in Science , provides the first experimental toolbox for studying the existence of animal cultures, thereby opening up an entire field of research.
