When current AI systems for detecting fake news flag content as false, they do not verify the facts: they calculate probabilities based on the data with which they have been trained. This is a fundamental misunderstanding, according to Dorsaf Sallami.

Top left: This view of the zebrafish ventricle reveals the emergence of future coronary vessels, made visible through two fluorescent lines that label endothelial cells as they form. Bottom left: Using different fluorescent markers, this image simultaneously shows nascent coronary vessels, cardiomyocytes, and proliferating cells, illustrating the synchronized growth of the vascular network and the cardiac muscle. Bottom right: This view highlights the parallel progression of the developing coronary vessels and the growing cardiac muscle tissue, each marked with a distinct fluorescent color that allows their coordinated maturation to be followed.

In this illustration, an asteroid (bottom left) breaks apart under the powerful gravity of LSPM J0207+3331, the oldest, coldest white dwarf known to be surrounded by a ring of dusty debris. Scientists think the system’s infrared signal is best explained by two distinct rings composed of dust supplied by crumbling asteroids.

Ce concept d'artiste représente une naine brune, un objet plus grand qu'une planète, mais pas assez massif pour déclencher la fusion de son noyau comme une étoile. Les naines brunes sont chaudes lors de leur formation et peuvent briller comme celle-ci, mais avec le temps, leur température se rapproche de celle des planètes géantes gazeuses comme Jupiter.
