Although this role as a climate buffer has helped slow the increase in global temperatures, it could soon become a factor of major instability. A team of researchers from the GEOMAR Helmholtz Center for Ocean … Read more

Understanding how massive stars die remains one of the concrete challenges of contemporary astrophysics. Although supernovae have been observed for decades, their exact dynamics, particularly during the first hours of the explosion, have until now eluded instruments. In April 2024, a rare event made it possible to fill this gap: the ultra-early detection of the … Read more

According to the latest studies, this banal habit raises real physiological and medical questions. Why … Read more
Sleeping well has never been a guarantee of brain health. When breathing goes wrong during the night, the whole brain suffers. Repeated apneas deprive the neurons of oxygen, weaken them and slowly exhaust them.
