The history of evolution is often told as a succession of exotic scenes populated by animals emerging at the heart of lush jungles. However, this idealized vision does not always reflect the reality of the beginnings of certain lines. The latest research shows that the origins of primates are not necessarily found in the protective … Read more
Human beings have always adapted their rest to the cycles of the sun and to variations in the natural world. However, as the cities have illuminated themselves and the screens have imposed themselves, these ancestral benchmarks were blurred.

The moon has ceased all geological activity for millions of … Read more

However, this apparent tranquility mask of invisible tensions that accumulate under the ice for millennia. As warming weakens permafrost, phenomena of rare violence occur and upset our understanding of these lands. This is how the explosive craters of Siberia now attract … Read more
Huntington is a rare, but dreaded hereditary disease, transmitted by a single defective gene, which leads to irreversible degeneration of the brain. Patients, often diagnosed in adulthood, gradually lose control of their movements, their cognitive capacities and their autonomy, without real therapeutic hope so far. This fatality could be questioned. For the first time, gene … Read more
