[School readiness survey of Montreal children starting school].

The aim of the survey was to provide a picture of the school readiness of 5-year-old Montréal children starting school and to identify disparities between neighbourhoods and the socio-economic factors determining these differences. 10,513 children were assessed using the Early Development Instrument. The results show that in Montréal, one child in three is vulnerable in at least one area of school readiness.

Effects of space environment on embryonic growth up to hatching of salamander eggs fertilized and developed during orbital flights.

In vertebrates, only few experiments have been performed in microgravity to study the embryonic development from fertilization. To date, these concern only amphibian and fish. We report here a study on the embryonic development of Pleurodeles waltl (urodele amphibian) eggs oviposited in microgravity.
