How ants self-organize to build their nests
Ants collectively build nests whose size can reach several thousand times that of individual ants and whose architecture is sometimes highly complex. However, their ability to coordinate several thousand individuals when building their nests remains a mystery. To understand the mechanisms involved in this process, researchers from CNRS, Université Toulouse III – Paul Sabatier and Université de Nantes 1 combined behavioral analysis, 3D imaging and computational modeling techniques.

Is autism hiding in a fold of the brain?
Is autism hiding in a fold of the brain?
Scientists at CNRS, Aix-Marseille Université and AP-HM have identified a cerebral marker specific to autism that can be detected by MRI and is present as from the age of two years. The abnormality thus detected consists in a less deep fold in Broca's area, a region of the brain specialized in language and communication, functions that are impaired in autistic patients.

Why prostate cancer is more aggressive in obese patients
Why prostate cancer is more aggressive in obese patients
Obesity has direct consequences on health and is associated with the onset of aggressive cancers, but the mechanisms underlying this phenomenon are little known. Researchers from the Institut de Pharmacologie et Biologie Structurale (CNRS/Université Toulouse III - Paul Sabatier) 1 have recently elucidated one of these mechanisms in prostate cancer, one of the most common cancers in men: in obese patients, the adipose tissue surrounding the prostate gland facilitates the propagation of tumor cells outside the prostate.
