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 […]

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 […]

Space debris mitigation satellite Shijian-21 recently docked with an old Chinese satellite to change its orbit. According to US tracking data, the “dead” satellite is now more than 3,000 kilometers from its place of origin. He no longer poses any danger. A scrapped Chinese satellite On October 24, China launched Shijian-21, described as a “satellite […]

Recent work based on a set of satellite measurements and field observations confirms the ability of boreal forests to modulate the reflectivity of low level clouds. However, this influence could moderate the future rise in temperatures on a continental scale. The results were published in the scientific journal Nature Geoscience. Forests have diverse and varied […]

While studying whales aboard an icebreaker in Antarctica, German researchers stumbled upon a whole different treasure. At the bottom of the Weddell Sea, more than 300 meters deep, were indeed the outlines of thousands of icefish nests, each guarded by a ghostly-looking relative whose dark pectoral fins were spread like bat wings on a clutch […]
