Radiotherapy : repair proteins in search of the ring to protect DNA
To understand why some cancer cells resist radiotherapy, an international team of researchers has used crystallography to “photograph” the first moments of the molecular ballet that allows these cells to repair their DNA. The study involved teams from the CEA, CNRS, SOLEIL (French synchrotron facility), University of Paris-Sud, Gustave Roussy, Aix-Marseille University and University Paul Sabatier - Toulouse III 1 .

Deciphering the link between skin allergies and the gut microbiota
Over the last few years, scientists have discovered connections between gut microbiota imbalances and various diseases. Now, in a study using mice, biologists from the CNRS, INSERM, and Claude Bernard Lyon 1 University -together with colleagues from the Institut Pasteur de Lille and the NIH (USA)- have revealed a surprising relationship between a viral detection system, the composition of the gut microbiota, and the development of skin allergies.

Pathology and social interactions : Safety in numbers
Pathology and social interactions : Safety in numbers
What if social behavior affected the progression of even noncontagious diseases' This is precisely what has been demonstrated by French CNRS teams, 1 with support from the French National Research Institute for Sustainable Development (IRD), Paris-Sud University, the University of Montpellier, the French Alternative Energies and Atomic Energy Commission (CEA), and colleagues from Spain and Australia.

The influence of genetics on nutritional requirements
The influence of genetics on nutritional requirements
Approximately 0.1%: that is the average genetic difference between two individuals. This small percentage is responsible for the variations of certain physical traits, such as eyes, hair, and height, but also for differences in our susceptibility to certain diseases and our capacity to absorb vitamins and phytomicronutrients (carotenoids, polyphenols, etc.), involved in the prevention of chronic disease.

A molecular label : traceability for medical implants
A molecular label : traceability for medical implants
A team of researchers at CNRS, Aix-Marseille Université and Université Paris 13 has demonstrated effective molecular labelling to unequivocally identify biomedical implants, even after a prolonged period inside the living being. These results were published in Angewandte Chemie International Edition on July 5, 2018.

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.

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.

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.

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.

Double trouble for a coral reef
Double trouble for a coral reef
Upolu, one of the nine islands of Samoa, in the Pacific Ocean. Well-known among fans of diving, this isolated coral reef promised to be a site of rich biodiversity for the scientists on the Tara Pacific expedition, principally from the CNRS, the CEA 1 and the King Abdullah University of Science and Technology (KAUST) in Saudi Arabia.

Targeting food aid for vulnerable populations more effectively
Targeting food aid for vulnerable populations more effectively
With uncertain future budgets for United Nations food aid, food security for refugee populations can only be achieved when aid is carefully targeted and effective. INRA researchers and their colleagues recommend taking simultaneous account of both individual and regionaland community-level data to effectively identify households facing food insecurity and/or economic vulnerability.

Eating less enables lemurs to live longer
Eating less enables lemurs to live longer
Chronic caloric restriction strongly increases the lifespan of a small primate, the grey mouse lemur. This is one of the results of a ten-year experiment conducted by researchers at the CNRS and the French National Museum of Natural History (MNHN), in partnership with other French teams. Chronic caloric restriction consists in eating a reduced but balanced diet from the outset of early adulthood.

BIABooster : a more sensitive device for characterizing DNA in blood circulation
Developed and patented 1 in 2012 and 2014 in the Laboratoire d'Analyse et d'Architecture des Systèmes (LAAS-CNRS) and implemented industrially by Picometrics-Technologies, BIABooster technology can characterize DNA with new precision and sensitivity. When used to analyze residual DNA circulating in the blood, it has identified promising signatures for monitoring patients with cancer.

How to make a good impression when saying hello
How to make a good impression when saying hello
You can hear the perfect hello. And now you can see it too. Researchers from the CNRS, the ENS, and Aix-Marseille University 1 have established an experimental method that unveils the filter—that is, mental representation—we use to judge people when hearing them say a word as simple as “hello”. What is the ideal intonation for coming across as determined or trustworthy? This method is already used by these researchers for clinical purposes, with stroke survivors, and it opens many new doors for the study of language perception.

A new solution for chronic pain
Neuropathic pain is a chronic illness affecting 7-10% the population in France and for which there is no effective treatment. Researchers at the Institute for Neurosciences of Montpellier (INSERM/Université de Montpellier) and the Laboratory for Therapeutic Innovation (CNRS/Université de Strasbourg) have uncovered the mechanism behind the appearance and continuation of pain.

A sobering conclusion: Adult hearts contain no stem cells
Marie Bannier, a former normal student in the Biology Department at the ENS de Lyon, participated in the research and writing of this scientific publication as part of her 4th year. During a myocardial infarction, commonly known as a heart attack, the blood supply to part of the heart muscle is cut off.
