Disarming a probiotic to improve its benefits
Disarming a probiotic to improve its benefits
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.

The genome of the pea assembled for the first time
The genome of the pea assembled for the first time
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.

Aboveground vegetation biomass in the tropics no longer has a positive impact on carbon stocks
Aboveground vegetation biomass in the tropics no longer has a positive impact on carbon stocks
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).

Artificial sweeteners: certain adverse metabolic effects revealed in a preclinical model
Artificial sweeteners: certain adverse metabolic effects revealed in a preclinical model
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.

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.

New prebiotics: benefits without the downsides?
New prebiotics: benefits without the downsides?
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.

DNA of ancient Roman and medieval grape seeds reveals unexpected links to modern grape varieties
DNA of ancient Roman and medieval grape seeds reveals unexpected links to modern grape varieties
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.

Bluetongue virus can hijack the cellular machinery of its host
Bluetongue virus can hijack the cellular machinery of its host
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).

A model to guide seed choices according to climate
A model to guide seed choices according to climate
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.

Tailor made interactions between the uterus and embryo
Tailor made interactions between the uterus and embryo
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.

Biodiversity matters: rare species play an essential role in ecosystem multifunctionality
Biodiversity matters: rare species play an essential role in ecosystem multifunctionality
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.

The secret multicellular lives of viruses
The secret multicellular lives of viruses
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.

Control of mosquito-borne diseases: discovery of a new genetic element in the Wolbachia bacterium
Control of mosquito-borne diseases: discovery of a new genetic element in the Wolbachia bacterium
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.

Crop plants could now reproduce clonally through seeds
Crop plants could now reproduce clonally through seeds
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.
