For how long have warm-blooded animals existed? The time at which this character first appeared in the ancestors of mammals has long been debated.

In order to determine the incubation temperature of eggs laid by non-avian dinosaurs, we analysed the oxygen isotope compositions of both eggshell carbonate ('18Oc) and embryo bone phosphate ('18Op) from seven oviraptorosaur eggs with preserved in ovo embryo bones.

The early Eocene (ca. Ma) was an interval of exceptional warmth with reduced pole-to-equator temperature gradients.

How do flocks, herds and swarms move through disordered environments? The answer to this question is crucial not only to animal groups in the wild, but also to effectively all applications of collective robotics and active materials composed of synthetic motile units1.

Research labs' collaborative initiatives putting the spotlight on political life With the approach of the presidential elections, researchers are coming together to conduct experiments, and to raise questions about the elections as well as the conduct of electoral campaigns.

Geometrical and mechanical models of virus assembly. The mechanical stress during assembly determines globally the final shape of a virus: compact (e.g.

We present scattered light images of the TW Hya disk performed with SPHERE in PDI mode at 0.63, 0.79, 1.24 and 1.62 micron.

Dissolution dynamic nuclear polarization (d-DNP) is a powerful method to enhance nuclear magnetic resonance (NMR) signals by several orders of magnitude, notably in 13C-labelled metabolites.

On January 9, Biology Master's students found themselves in class, no surprise there, except that this time, it was their turn to teach! On the program: antibiotics for elementary school students, microbiota for high school students and genome for college students.
