New discovery on iron metabolism improves anemia treatment
Anemia is a major public health problem worldwide, affecting around a third of the population. There are many causes of anemia, but the most common are a defect in the production of red blood cells, a lack of iron in the blood or genetic diseases such as thalassemia. A better understanding of iron metabolism is essential to improve management of the many patients affected.

Improving the treatment of anaemia thanks to a new discovery in iron metabolism
An essential component of the haemoglobin in red blood cells, iron is crucial to many biological processes - including the transport and storage of oxygen in the body. © Inserm/Claude Féo Anaemia is a major public health problem worldwide, affecting around one third of the population. Its causes are multiple, but the most common are a lack of red blood cell production, a lack of iron in the blood, and genetic diseases such as thalassaemia.

Food additive E551 could promote coeliac disease
A recent study has found that food additive E551, also known as silicon dioxide, can reduce oral tolerance to dietary proteins and could foster the development of coeliac disease. Born of a collaboration among researchers at INRAE and McMaster University in Canada, this pioneering work is the first to highlight the potential toxicity of E551, a nanometric ingredient that is added to a wide range of consumer food products.

Impacts of the European Green Deal on the agrifood sector
Researchers at INRAE analysed the market and non-market impacts of the European Green Deal on the European agrifood system. Substantial positive impacts on the climate, the environment and public health require simultaneous action on agricultural production, food losses and waste, and eating patterns.

New cell senescence discoveries open up therapeutic avenues in fighting age-related diseases
An increase in glycerol kinase (GK) enzyme activity on its own is capable of halting cell proliferation and initiating a programme of senescence. The blue staining of the cells is a biomarker of senescence. This image shows cells overexpressing the GK enzyme. Khaled Tighanimine/team Mario Pende. Cell senescence is a physiological process that has been associated in many studies with age-related diseases.

The consumption of certain food additive emulsifiers may increase the risk of cancer
The consumption of certain food additive emulsifiers may increase the risk of cancer
Emulsifiers are among the additives most widely used by the food industry, helping to improve the texture of food and extend its shelf life. Researchers from Inserm, INRAE, Université Sorbonne Paris Nord, Université Paris Cité and Cnam, as part of the Nutritional Epidemiology Research Team (CRESS-EREN), have undertaken to study the possible links between the dietary intake of food additive emulsifiers and the development of cancer.

An exceptionally well-preserved fossil deposit discovered in southern France
An exceptionally well-preserved fossil deposit discovered in southern France
A new fossil deposit has been unearthed in the Hérault region thanks to the long-term work of a couple of amateur paleontology enthusiasts, whose discoveries have been studied by an international team involving scientists from the CNRS (1) and the University of Lausanne. With over 400 fossils dating back 470 million years, the Cabrières site near Pézenas bears witness to the closest environment ever observed to the South Pole at that time.

Back to the future: not all grape varieties succumbed to the extreme heat wave of 2019
Heat waves are increasingly common worldwide, making it necessary to adapt our crops. A new study by INRAE and Institut Agro, based on an experiment conducted during an unprecedented heatwave in France in June 2019, has uncovered regions of grapevine genome associated with extreme heat tolerance. The results were published on 7 February in New Phytologist.

Back to the future: 2019’s extreme heatwave didn’t kill all grape varieties
As heatwaves intensify in France, we need to adapt our crops. A new study by INRAE and Institut Agro reveals the genome regions involved in tolerance to extreme temperatures in grapevines - thanks to an experiment using the exceptional canicular episode of June 2019. Results published on February 7 in New Phytologist.

Type 2 diabetes: discovery of a new biological cardiovascular risk marker
Type 2 diabetes: discovery of a new biological cardiovascular risk marker
Scientists from Inserm, Université Paris Cité and CNRS at the Necker Enfants Malades Institute in Paris have identified a new prognostic marker for cardiovascular risk in people with type 2 diabetes (T2D). Led by Inserm researcher Nicolas Venteclef, the team has shown that the number of white blood cells circulating in the blood, as well as certain subtypes, is associated with stroke or myocardial infarction risk over the next ten years.

Optimising global crop yields to meet growing food demand
An INRAE study conducted in collaboration with the University of Minnesota reveals global disparities between current and attainable agricultural yields, underscoring the importance of optimising agricultural practices by 2050 in the face of growing global demand. The researchers highlight crop growth potential for several crops, including maize, cassava and sorghum, and warn that rice yields could stagnate in Asia.

HIV: early treatment, one key to remission
HIV: early treatment, one key to remission
People living with HIV need to take antiretroviral treatment for life to prevent the virus from multiplying in their body. But some people, known as "post-treatment controllers,- have been able to discontinue their treatment while maintaining an undetectable viral load for several years. Starting treatment early could promote long-term control of the virus if treatment is discontinued.

Discovery of immense fortifications dating back 4,000 years in north-western Arabia
Digital reconstruction of the rampart network from the northern section of the Khaybar walled oasis 4,000 years ago. Khaybar Longue Durée Archaeological Project, M. Bussy & G. Charloux The North Arabian Desert oases were inhabited by sedentary populations in the 4 and 3 millennia BCE. A fortification enclosing the Khaybar Oasis-one of the longest known going back to this period-was just revealed by a team of scientists from the CNRS 1 and the Royal Commission for AlUla (RCU).

Ancestors of primates lived in pairs
Ancestors of primates lived in pairs
A study carried out by CNRS 1  scientists working with an international team has revealed that around 70 million years ago, when dinosaurs existed, the ancestors of primates most commonly lived in pairs. Only 15% of them opted for a solitary lifestyle. This discovery - that our ancestors adopted variable forms of social organization - challenges the hitherto commonly accepted hypothesis that at the time of dinosaurs, the ancestors of primates lived alone, and that pair living evolved much later.

Asbestos: the size and shape of inhaled nanofibres could be exclusively responsible for the development of pulmonary fibrosis
The pathogenic potential of inhaling the inert fibrous nanomaterials used in thermal insulation (such as asbestos or fibreglass) is actually connected not to their chemical composition, but instead to their geometrical characteristics and size. This was revealed by a study, published on 3 January 2024 in the journal Nature Nanotechnology , conducted on glass nanofibers by a French-Chinese team including a CNRS chemist.

Publication of the Physics Laboratory and Chemistry Laboratory in the journal Langmuir on November 16, 2023. News by CNRS Chemistry on December 19, 2023. Water flowing over soluble rocks can create patterns of multiple troughs bordered by sharp ridges. By combining field measurements, a numerical model and laboratory experiments, a team led by the MSC laboratory (CNRS/Université Paris Cité), in collaboration with the LPG (CNRS/Nantes Université/Université d'Angers) and the RDP (CNRS/ENS de Lyon/Inrae) has shown that the appearance of these shapes results from a geometric mechanism.
