Women and Parkinson’s Disease: Physical Activity Found to Be Beneficial More Than Twenty Years Before Diagnosis
Although physical activity is regularly discussed as being one of the avenues for preventing Parkinson's disease (PD), studies so far had been unable to eliminate certain biases or had not focused on its specific role in women. Researchers from Inserm, Université Paris-Saclay and Université de Versailles Saint-Quentin-en-Yvelines (UVSQ) with the Gustave Roussy Institute studied the impact of physical activity on the development of PD in nearly 100,000 women from the French cohort E3N followed up over 29 years.

Eating Broccoli to Limit Skin Allergies
Eating Broccoli to Limit Skin Allergies
The severity of skin allergies can vary depending on many environmental factors, including diet. However, the role of specific nutrients had not been well documented until now. In a new study, researchers from Inserm and Institut Curie at the Immunity and Cancer unit have shown that the absence in the diet of compounds found in certain vegetables, particularly broccoli and cabbage, could worsen skin allergies in animal models.

Species that eliminate a third of their genome in somatic cells
Publication of the LBMC in the journal Current Biology, on August 21, 2023. Communication of CNRS-INSB on August 30, 2023. Some animal species systematically destroy part of their DNA in their somatic cells. Why do they do this? But how? This programmed elimination of the genome, discovered 150 years ago, remains mysterious in the absence of suitable means of study.

Towards a Better Understanding of the Role of Male Hormones in Women with Multiple Sclerosis
The image shows the brain region where demyelination is typically induced. The red cells correspond to all of the microglial cells with inflammatory properties when demyelination has just occurred. If the spontaneous regeneration process of myelin is effective, their inflammatory nature then diminishes in favor of an anti-inflammatory and pro-regenerative nature.

Laure Bonnaud-Ponticelli: 'The octopus has phenomenal analytical capacities!'
Laure Bonnaud-Ponticelli: ’The octopus has phenomenal analytical capacities!’
Gone are the days when the octopus was, in the collective imagination, a frightening sea monster attacking Jules Verne's Nautilus. The image of the octopus has now changed. For example, the cephalopod took on the pseudonym Paul during the 2010 soccer World Cup, and made predictions about the outcomes of games (more or less successfully.

Pre- and Postnatal Chlordecone Exposure Could Affect the Cognitive Development and Behavior of Children
Chlordecone is an organochlorine insecticide that was used in the French West Indies from 1973 to 1993 to control the banana root borer. Adobe Stock Despite the fact that chlordecone has not been used as an insecticide in the French West Indies for 30 years now, its persistence in the environment continues to contaminate the populations.

How the microbiota stimulates growth
How the microbiota stimulates growth
1 While insulin-like growth factor 1 (IGF-1), mainly produced by the liver, has a chemical structure similar to that of insulin, these hormones have distinct functions: IGF-1 stimulates tissue and skeletal growth, whereas insulin regulates energy metabolism as required for growth. The gut microbiota is now thought to constitute an organ in its own right.

A blood factor involved in depression
A small group of neural stem cells isolated from mice and cultured in vitro observed under a confocal microscope. The process of aging is often related to the onset of cognitive decline, depression and memory loss. Scientists from the Institut Pasteur, CNRS and Inserm have discovered that administration of the GDF11 protein, which is known to regenerate murine neural stem cells, improves cognitive abilities and reduces the depressive state in aged mice.

Who are the first ancestors of present-day fish?
Who are the first ancestors of present-day fish?
What is the origin of the ancestors of present-day fish? What species evolved from them? A 50-year-old scientific controversy revolved around the question of which group, the "bony-tongues” or the "eels”, was the oldest. A study by INRAE, the CNRS, the Pasteur Institute, Inserm and the Muséum National d'Histoire Naturelle , has just put an end to the debate by showing through genomic analysis that these fishes are in fact one and the same group, given the rather peculiar name of "Eloposteoglossocephala”.
