The European night sky is far from an empty space. Every night, migratory birds cross it at high altitude, guided by the stars and magnetic fields. But some of these travelers will cross paths with an unexpected hunter. Still unknown to the general public, the great noctule reinvents the rules of aerial predation. This discreet … Read more
At over 4,000 meters above sea level, in the heart of the Chilean Andes, 76 V-shaped stone structures have been identified in the Camarones River basin. Long ignored, these installations discovered thanks to satellite imagery reveal an elaborate collective hunting system, which may date back more than 6,000 years. These traps for vicuñas (a South … Read more
The intestine is not just a digestive organ. In recent years, it has fascinated as much as it has raised questions, as its links with the immune system have proven to be complex. At the intersection of genetics, the environment and the microbiota, certain chronic diseases find a favorable, but still poorly understood, terrain. It … Read more
Humans have always projected their hopes, fears and dreams into the animal kingdom. Among all the species around us, only one shares our homes, our habits and sometimes even our most subtle emotions. This proximity, woven over millennia, has profoundly modified the way in which dogs understand us. But can this complicity go so far … Read more

It beats relentlessly, second by second, from our first breath. The heart embodies vital constancy, but also an enigma that science is still exploring. Because if it is the symbol of endurance, can it also be optimized like an economical muscle? This is precisely what a new study on resting heart rate reveals, which challenges … Read more
As the boundaries between wild spaces and inhabited territories become blurred, certain ancient balances begin to falter. Where the forest once receded slowly, the sudden advance of human activities is disrupting interactions between species. In several regions of Brazil, this new porosity transforms familiar game into a silent vector. The transmission of leprosy by the … Read more
Understanding the mechanisms of success has long fascinated cognitive sciences. But it is often failure that most profoundly shapes individual trajectories. Behind a simple defeat, an invisible process sometimes begins, capable of lastingly reprogramming our behavior. Researchers are now interested in this silent phenomenon called the “loser effect”, an effect with much more far-reaching consequences … Read more
Mars, an arid and silent planet, seemed frozen under its thin reddish atmosphere. However, beneath this apparent tranquility, forces much more intense than imagined regularly agitate its surface. New visual data, crossed with large-scale automated analyses, today reveal the existence of violent winds on Mars, capable of raising columns of dust at unsuspected speeds. These … Read more
Knowing the truth has never been enough to make people act. Since childhood, our relationship with information depends not only on what we know, but on what we choose to know.
