A molecule that can improve the efficiency of chemotherapy
A molecule that can improve the efficiency of chemotherapy
A team of researchers from the CNRS and Université Nice Sophia Antipolis 1 has just shown that a small molecule called methiothepin can inhibit the chemotherapy resistance of certain tumors. These results will be on the cover of the July 1, 2018 issue of International Journal of Cancer . Cancerous tumors are also capable of “detoxing,” subsequently limiting the efficiency of chemotherapy.

The effect of a cocktail of low-dose pesticides via the diet: initial findings in animals have demonstrated metabolic disturbances
The effect of a cocktail of low-dose pesticides via the diet: initial findings in animals have demonstrated metabolic disturbances
INRA scientists, working with their colleagues from INSERM, have studied in mice the effects of chronic oral exposure to a low-dose pesticide cocktail. Their results have demonstrated metabolic disturbances in vivo that differ as a function of sex. Indeed, males exposed to the pesticides gained weight and became diabetic, while females were protected from these effects but displayed other disturbances.

Digital technologies and plant production: predict and act
Digital technologies and plant production: predict and act
Connected hives, decision-support tools in viticulture, precision spraying, the use of drones, etc.; digital technologies now form part of the daily activities of farmers and presage a new vision for agriculture in the future. On 26 June 2018 in Montpellier, INRA, IRSTEA and the #DigitAg Institute for the Convergence of Digital Agriculture organised the Crossroads for Agricultural Innovation (CIAg) meeting on "Digital Technologies and Plant Production: Predict and Act".

Asylum seekers are not a "burden" for European economies
Does the arrival of asylum seekers lead to a deterioration in the economic performance and public finances of the European countries that host them? The answer is no, according to economists from the CNRS, Clermont-Auvergne University, and Paris-Nanterre University, 1 who have estimated a dynamic statistical model based on thirty years of data from fifteen countries in Western Europe.

When young children learn to eat a wide variety of textures
When young children learn to eat a wide variety of textures
How do young children aged between 6 and 18 months learn to eat different textures' Which textures do they accept as a function of their age? For the first time in France, INRA scientists working in collaboration with Blédina have studied these questions 1 . They showed that children accepted small quantities of most textures at an earlier age than their parents usually propose them at home.

Jacket for cardiorespiratory monitoring of laboratory animals
Jacket for cardiorespiratory monitoring of laboratory animals
To meet their objective of offering connected devices for the physiological monitoring of laboratory animals without recourse to anesthesia or surgery, researchers from the TIMC-IMAG laboratory (CNRS / Université Grenoble Alpes / Grenoble INP / VetAgro Sup) have developed a jacket that measures rodent cardiac and respiratory activity.

Pandoravirus : giant viruses invent their own genes
Three new members have been isolated and added to the Pandoravirus family by researchers at the Structural and Genomic Information Laboratory (CNRS/Aix‐Marseille Université), working with partners at the Large Scale Biology Laboratory (CEA/Inserm/Université Grenoble‐Alpes) and at CEA-Genoscope.

Bees and the thought of naught
Bees and the thought of naught
Honeybees can conceive and interpret zero. This has just been demonstrated by a scientist from the Research Centre on Animal Cognition (CNRS / Université Toulouse III—Paul Sabatier) and her Australian colleagues, proving for the first time ever that insects are capable of mathematical abstraction. As zero, designating nothingness, neutrality, or absence, is a relatively recent concept for humans, Though some vertebrates had already been shown to master complex numerical concepts like addition and zero, no evidence of this existed for insects.

The search for the origin of mast cells
A team of researchers from CNRS, INSERM and Aix-Marseille Université (AMU) at the Centre of immunology (Marseille-Luminy (CIML), together with the Singapore Immunology Network (SIgN) 1 , has proven that not all of the immune system's important mast cells are produced in bone marrow, as was previously thought.

Bacteria ensure square meal for bloodsucking ticks
Bacteria ensure square meal for bloodsucking ticks
How do ticks live solely on blood? A study presented in Current Biology (May 31, 2018) has elucidated the crucial role played by symbiotic bacteria that synthesize B vitamins. These nutrients are scarcely found in the blood ticks ingest but are essential to their life cycle. Thus ticks cannot survive to adulthood or reproduce without their bacterial symbionts.

First light for SPIRou, exoplanet hunter
SPIRou, the new planet-hunting spectropolarimeter developed for the Canada-France-Hawaii Telescope (CFHT), has successfully recorded its first starlight. Ten years after it was first designed and following four intensive months of installation at CFHT, this international instrument in which France has played a leading role is on the point of initiating its scientific operations, namely the detection of exoplanets around nearby red dwarf stars and the study of newborn stars and planets.

A supergene to stay alive
Some butterflies rely mainly on colorful wing patterns for their survival. CNRS researchers from the Centre d'Écologie Fonctionnelle et Évolutive (CNRS / University of Montpellier / Paul-Valéry University / EPHE-PSL / IRD), together with British and American teams, studied the genomes of dozens of tropical Heliconius numata butterflies to understand how such diversity in color motifs has come about.

Discovery of the first body in the Solar System with an extrasolar origin
Discovery of the first body in the Solar System with an extrasolar origin
Asteroid 2015 BZ509 is the very first object in the Solar System shown to have an extrasolar origin. This remarkable discovery was made by CNRS researcher Fathi Namouni and her Brazilian colleague Helena Morais, and is published on 21 May 2018 in MNRAS . Could some bodies in our Solar System come from the vicinity of other stars' Astronomers are in disagreement about comets, with some arguing that certain comets may have formed around other stars before being captured by the Sun, although they have never been able to prove it.

The survival of sea birds affected by ocean cycles
In a general context of climate change, researchers at the Centre d'écologie fonctionnelle et évolutive (CNRS/Université de Montpellier/Université Paul Valery/EPHE-PSL) and their international partners revealed the impact of ocean cycles, such as the Pacific decadal oscillation and El Niño, on the survival of the Nazca booby, a species found on the Galapagos Islands.

Fish in schools can take it easy
Fish in schools can take it easy
Using a new computer model, researchers at the Ecole Centrale de Marseille and CNRS have shown that a fish expends less energy when it swims in a school, because neighbouring fish produce a 'suction' effect. This work will be published on 11 May 2018 in Physical Review Letters . Schools of fish provide a fascinating example of collective behaviour in which the group moves in a coordinated manner without the need for a leader.

The Big Bell Test : participatory science puts quantum physics to the test
The Big Bell Test : participatory science puts quantum physics to the test
Quantum chance is intrinsically different than classic chance. That is what the violations of Bell inequalities, a crucial step in understanding quantum mechanics, states. One drawback remains though: until now, testing these inequalities relied on experimental configurations that use parameters set from data generated by quantum systems.

Why plants are so sensitive to gravity : The lowdown
Why plants are so sensitive to gravity : The lowdown
Plants can detect the slightest angle of inclination. Yet the mechanism by which they sense gravity relies on microscopic grains. In theory, such a system should hardly allow for precise detection of inclination. Researchers from the CNRS, the French National Institute of Agronomic Research (INRA), and Université Clermont Auvergne have now explained this curious paradox.
