To form an organism, embryonic tissues must fold and move in a perfectly coordinated manner during gastrulation. In a study published in Nature Communications, scientists demonstrate, using Drosophila, that the internalization of the mesoderm does not depend solely on the forces it generates. It also requires precisely tuned resistance from neighboring tissues, whose intensity, location, and symmetry are critical.

Researchers have developed a numerical method that enables the thermal behaviour of solids at very low temperatures to be calculated without approximations, when quantum effects influence heat diffusion.

Cyril Picard, a member of LIPhy, contributed to the writing of "Étonnants Matériaux", a new book published by CNRS Éditions that invites readers to explore the behind-the-scenes world of materials science research, at the intersection of innovation, environmental challenges, and the applications of tomorrow.
