A study shakes up received ideas on male domination among primates
According to a new scientific study, conflict between males and females is very frequent among primates, representing over half of all conflicts. The winning gender in confrontations varies considerably from one species to another 1 . Strict dominance (over 90% of confrontations won) for either gender was observed in less than 20% of the populations studied.

Fatty diets and obesity affect the structure and function of astrocytes 1 , the star-shaped brain cells located in the striatum, a brain region involved in the perception of pleasure generated by food consumption. What is even more surprising is that by manipulating these astrocytes in vivo in mice can influence metabolism and correct certain cognitive changes associated with obesity (ability to relearn a task, for example).

A new class of molecules against cancer cells refractory to standard treatments
A new class of molecules capable of killing the cancer cells that are refractory to standard treatments and responsible for recurrence has just been developed by scientists at Institut Curie, the CNRS, and Inserm. This crucial advance in the fight against metastatic cancer is based on identifying the cellular site for ferroptosis initiation, a natural process, catalysed by iron, that sparks the oxidative degradation of cell membranes.

Artificial intelligence and brain cancer: new mapping to improve diagnosis and management of glioblastoma
While glioblastoma is a highly aggressive brain tumor that currently offers little hope of cure, researchers at the CANTHER laboratory (CNRS / Inserm / University of Lille / Lille University Hospital / Pasteur Institute of Lille) and the Laboratoire de Bioimagerie et Pathologies (CNRS / University of Strasbourg) have succeeded in identifying different forms of this tumor and mapping them precisely by analyzing the activity of gene regulatory factors.

Food additive mixtures are an everyday feature of our diets, especially through ultra-processed foods. Until recently, safety evaluations of these additives have been conducted substance by substance due to a lack of data on the effect of them ingested together. In a new study, researchers from Inserm, INRAE, Sorbonne Paris Nord University, Paris Cité University and Cnam, as part of the Nutritional Epidemiology Research Team (CRESS-EREN), examined the possible links between exposure to mixtures of commonly consumed food additives and the onset of type 2 diabetes.

A French team coordinated by a CNRS 1 scientist has highlighted the harmful impact of chronic exposure to tebuconazole, one of the fungicides most widely used in agriculture in Europe, on sparrow reproduction. The results of this research, published in the journal Environmental Research , reveal a direct link between exposure to this fungicide and abnormal growth in sparrow chicks, as well as higher mortality in these young birds, particularly females.

Since 2000, the world's glaciers have lost 5% of their initial volume, and 273 billion tonnes of ice are disappearing every year - the equivalent of 3 Olympic swimming pools per second. These are the results of an in-depth study of the global evolution of glaciers (excluding the Antarctic and Greenland ice sheets) between 2000 and 2023, based for the first time on a combination of field measurements and satellite observations.

First detection of an ultra-high-energy neutrino
An extraordinary event consistent with a neutrino with an estimated energy of about 220 PeV (220 x 1015 electron volts or 220 million billion electron volts), was detected on February 13, 2023, by the ARCA detector of the kilometre cubic neutrino telescope (KM3NeT) in the deep sea. This event, named KM3-230213A, is the most energetic neutrino ever observed and provides the first evidence that neutrinos of such high energies are produced in the Universe.
