Producing bug-free software that does what it is supposed to do sometimes requires a miracle. As well as tests, formal logic and mathematics tools are used to guarantee reliability. Xavier Leroy, an expert in semantics, reflects on programming.

When was Jerusalem founded? What was its history? Calling into question the Bible version, which took precedence until now, dozens of digs carried out by Israeli archaeologists are upsetting the official history. Hypotheses on the size of the town around 2000 years BCE, prior to the arrival of the Israelites, remain controversial.

This year, the Deep Carbon Observatory will be ten years old.

The climate policies aimed at achieving the ambitious goal of stabilising global warming at 2°C, stipulated in the 2015 Paris Agreement, are going to cost a lot of money.

Fungi are key actors in biodiversity. We are gradually discovering the fundamental role they play in the proper operation of ecosystems. Specialist in this field, Francis Martin, a microbiologist at INRA, has discovered how these organisms dialogue with trees

Unlike the moral rules, the major laws of bioethics anticipate their own senescence because they must confront a permanent change.

Why do we age? Work on the underlying biological process suggests that, without necessarily becoming eternal, we could limit the consequences of aging on memory and cognition.
