Researchers from INRA and CNRS 1 , in collaboration with German, Spanish, English and Canadian teams, have examined the effect of field size and crop diversity on biodiversity in agricultural landscapes. Published in PNAS , their work shows that increasing the complexity of the crop mosaic produces a considerable (and largely under-exploited) benefit in conserving and restoring the biodiversity of farm landscapes, while maintaining areas of land under agricultural production.
Scientists from INRA, CEA, CNRS, CNES and several international universities 1 have quantified - over the 2010-2017 period ' the time changes in the carbon stocks of aboveground vegetation biomass in the tropics. One main result is that over the studied time period, these stocks are almost constant: gains in biomass carbon stocks in some regions of the tropics are compensated by losses due to deforestation or diebacks linked to climate impacts (in particular the El Niño events).
Often, hypoallergenic formulas are recommended for infants who are not exclusively breastfed and who are at risk of developing allergies. While it is assumed that such formulas reduce the development of allergies later in life, it is unclear whether this claim is true. A team of INRA and INSERM researchers have shown that the consumption of partially hydrolysed (hypoallergenic) formulas was not associated with a reduced risk of developing allergies, findings that were recently published in the journal Pediatric Allergy and Immunology .
Prebiotics are currently a preferred treatment for certain metabolic disorders, as they can restore the balance of dysfunctional gut microbiota, and improve the body's metabolism. However, these substances have to be used at high doses, which can result in patients experiencing bloating and flatulence.
A team of researchers from the CNRS, INRA, and the University of La Rochelle is now the first to have demonstrated that organic farming benefits honeybee colonies, especially when food is scarce in late spring. The scientists analysed six years of data collected through a unique system for monitoring domesticated bees that is unparalleled in Europe.
To produce a significant reduction in mortality due to fine particulates, their average level should be reduced by at least 3 micrograms per m3 as a yearly average, concludes an interdisciplinary study led by researchers from Inserm, the CNRS, INRA, Atmo Auvergne Rhône-Alpes and the Université Grenoble Alpes.
The natural lipids in buttermilk could contribute to reducing cardiovascular risk in vulnerable populations
A French consortium led by INRA, in collaboration with INSERM, the Universities of Lyon and Clermont Auvergne, Lyon Civil Hospitals and the Human Nutrition Research Centres (CRNH) of Rhône-Alpes and Auvergne, have now demonstrated that consuming certain lipids present naturally in dairy products (called "polar lipids") could reduce the cardiovascular risk in overweight postmenopausal women by lowering their blood levels of LDL-cholesterol ("bad" cholesterol) and triglycerides.

Which grape varieties were popular for making wine in ancient times' Do they resemble those in use today? An international consortium which included INRA, the CNRS and the University of Montpellier1 has shed new light on viticulture in ancient Rome and the Middle Ages. Researchers sequenced the DNA of 28 grape seeds found on archaeological sites in France and compared their genomes to those of modern grape varieties.
Researchers at INRA, ANSES, and ENVA have discovered that bluetongue virus can enhance its replication by exploiting one of its host's cellular pathways. Published in the Journal of Virology , their results could help the quest to identify effective antiviral compounds for combating the virus. Bluetongue virus (BTV) can infect wild and domestic species of ruminants (ovines, caprines, and bovines).
In an article published May 30, 2019 in the British Medical Journal , researchers from Inserm, Inra, Université Paris 13 and Cnam in the Nutritional Epidemiology Research Team (EREN) report an increased risk of cardiovascular disease in consumers of ultra-processed foods in the NutriNet-Santé cohort.
First patents to cover the fundamental processes for accessing the human gut microbiome as biotherapeutics. MaaT Pharma's microbiome sample collection and administration devices receive CE mark for use in collecting and administrating gut-derived samples as biotherapeutics to patients.
How do you know if a seed is well suited to a given environment? How can you predict its yield for a particular climate? Farmers need to know the answers to these questions when choosing their seeds because yields depend on complex interactions between seed genotype and environmental conditions. Researchers at INRA and Wageningen University & Research (WUR, Netherlands) have developed a model to predict the yield of any maize hybrid based on its genes and environmental conditions.
Atmospheric CO2 levels have risen by 30% in a century. A Franco-Australian study by scientists from INRA, James Cook University and the Commonwealth Scientific and Industrial Research Organisation (CSIRO) has evaluated the global impact of rising atmospheric CO2 levels on the terrestrial vegetation that uses this gas as a source to drive its growth.
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.
