Scientists from Inra and the Scuola Superiore Sant'Anna (Italy) have shown that not all weed communities (spontaneous vegetation) generate crop yield losses, even in unweeded conditions, and that high weed diversity is associated to a reduced risk of important crop yield losses.

Since 2013, a European Union (EU) moratorium has restricted the application of three neonicotinoids to crops that attract bees because of the harmful effects they are deemed to have on these insects. Yet researchers from the CNRS, INRA, and the Institut de l'Abeille (ITSAP) have just demonstrated that residues of these insecticides-and especially of imidacloprid-can still be detected in rape nectar from 48% of the plots of studied fields, their concentrations varying greatly over the years.
Scientists from Inra and the Scuola Superiore Sant'Anna (Italy) have shown that not all weed communities (spontaneous vegetation) generate crop yield losses, even in unweeded conditions, and that high weed diversity is associated to a reduced risk of important crop yield losses. Published in Nature Sustainability , these results provide new grounds for sustainable weed management.
Researchers from INRA and CNRS have shown for the first time that bee pollination surpasses the use of pesticides in yield and especially in profitability of oilseed rape. The team of researchers analysed data collected over four years in farmers' fields in an agricultural plain in Deux-Sèvres (Nouvelle Aquitaine, western France).
For more than a century, the Nissle 1917 strain of the bacterium Escherichia coli has been used as a probiotic to treat gastrointestinal disorders. However, this bacterium also produces a toxin, colibactin, which has deleterious effects on host DNA and might cause colon cancer. It is therefore crucial to understand the mechanisms at play in the strain if we wish to limit undesirable side effects.
Evanescent Acoustic Beam Moves Suspended Particles at Lower Cost & Energy Consumption Than Existing Propagative Surface Acoustic Wave (SAW) Systems. CEA-Leti has developed a new acousto-microfluidic technology for manipulating microand nanoscale samples using evanescent sound waves. Described in a paper published in the September issue of Nature (Comm.
An international team * led by researchers from INRA and CEA managed to assemble the first sequence of the pea genome. This study, published on September 2, 2019 , will, in addition to increasing knowledge of this genome compared to that of other legumes, help to improve traits of interest for peas, such as disease resistance, regularity of yield and nutritional value.
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).
INRA researchers, in collaboration with the University of Adelaide, Australia, studied the effects that a widely used artificial sweetener blend, i.e. acesulfame K-sucralose, has on metabolism. For the first time, they revealed ' in animals ' an increase in glucose absorption, particularly in the brain and fatty tissues, indicating certain undesirable effects on metabolism and insulin sensitivity.
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 .
Weebit Nano and CEA-Leti to demonstrate brain-inspired neuromorphic demo
The demo enables massively parallel, low-power and low-latency computation abd will be demonstrated at Flash Memory Summit 2019, August 6-8. Weebit Nano (ASX: WBT), the Israel-based semiconductor company seeking to develop and commercialize the next generation of memory technology, and CEA-Leti, a global leader in miniaturization technologies enabling smart, energy-efficient and secure solutions for industry, will demonstrate a new neuromorphic demo able to perform precise object recognition tasks in an energy-efficient manner at Flash Memory Summit 2019.

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).
