A team of researchers has found that with continued global warming, the ocean is gradually losing its “memory”. These results, published on May 6 in the journal Science Advances, have strong implications for seasonal predictability and the socio-economic sectors that depend on it. The ocean has considerable thermal inertia. A familiar example is the seaside […]

Most stars evolve within galaxies, separated from each other by distances beyond comprehension. The intergalactic space (between each galaxy) seems empty, but it is not entirely so. Some solitary stars indeed sometimes wander there. For the first time, astronomers believe they have found one of these stars brain dead. It could be the first known […]

A study led by the University of Ghent (Belgium) within the framework of the European scientific program DRY-2-DRY has for the first time demonstrated the propensity of droughts to self-propagate and, in fact, to increase the surface subjected to water deficit. The results were published in the journal Nature Climate Change. Recently qualified as the […]

In Guatemala, archaeologists have discovered the oldest recorded evidence of the Mayan calendar: two fragments of wall paintings. When assembled, these reveal a notation known as “7 stags”. Details of the study are published in the journal Science Advances. Four Mayan Calendars The Maya had four calendars. One is the sacred divination calendar or Tzolk’in. […]

A recent French study highlights the significant pollution emanating from astronomy research. This work is emerging at a time when all sectors of activity must reduce their CO2 emissions as much as possible. Astronomy emits a lot of CO2 Today, the fight against greenhouse gas emissions is a global priority. In November 2021, the Global […]

Jointly developed by the European Space Agency and Russia, the ExoMars 2022 mission was to be launched in September with the objective of probing for the presence of extraterrestrial life. The conflict in Ukraine ultimately led to a rift between the two sides. Now the ESA is trying to revise its plans without Russia. In […]

Methane (CH4) currently contributes up to 20% of anthropogenic global warming. However, a study maintains that the changes observed since 2010 in the rate of increase in methane are mainly linked to emissions from tropical continents. The results were published in the journal Nature Communications on March 16. Remember that since the beginning of the […]

Anesthetics are an integral part of medicine today and include a range of drugs used to simply manage pain or render patients completely unconscious. Propofol is the most commonly used anesthetic by doctors today, allowing for a relatively side-effect-free recovery after surgery, but this was not always the case. manage the pain Anesthesia as we […]

New work published in the journal Nature Communications on February 22 shows how the growing influx of tourists to Antarctica is leading to an increased rate of melting near the most visited sites on the peninsula. The exotic, virgin and immaculate dimension of the Antarctic landscape makes it an increasingly popular place for tourists. With […]

A child’s tooth found in a French cave is the oldest known evidence of the existence of modern humans in Western Europe. The tooth fragment suggests that our ancestors were evolving in place at least 54,000 years ago, about 10,000 years earlier than previously thought. The oldest fossils of early modern humans outside of Africa […]
