One of the crucial stages of gestation is implantation of the embryo in the uterus, in contact with a tissue called the endometrium. However, the mechanisms that enable this implantation remain largely unclear. A Franco-American collaboration co-led by INRA research scientists has revealed that intense and fine-tuned crosstalk is established between the embryo and endometrium, allowing them to adapt to each other. Working in cattle, the scientists analysed the expression of genes in the embryo and endometrium at the start of gestation. They showed that many of the biological processes at work in the two tissues are closely correlated.

In order to carry out studies of facial behavioural indicators, INRA scientists teamed up with the Beauval Zoo to look at blue-and-yellow macaws (Ara ararauna), who have the distinctive characteristic of having a portion of their cheeks devoid of feathers. During their experiment, the scientists were able to describe for the first time facial expressions in the birds within a context of positive valence: the macaws blushed and ruffled their crown feathers.
