1 Under the ice of Antarctica, a volcano wakes up after more than 2,000 years of inactivity.
By tracing rare gases in the water, the researchers found relatively large quantities of helium 3, an indicator of volcanism.
According to the measurements carried out, there is a source of an active volcanic heat because it is 25 times greater than what what would expect from an extinct volcano. However, it is too early to comment on the impact of this heat source on melting ice.
2 The RemoveDebris satellite was launched on June 20 and is to test three technologies that can remove space debris by moving them out of orbit.
Rather than cleaning the space of all the debris that clutter it, the idea that prevails today is to remove only the most dangerous debris, that is to say those likely to collide with a satellite, a space station or any other space infrastructure.
A net, an optical navigation system and an Airbus harpoon are the three technologies that will be tested in orbit.
3 US health authorities have for the first time authorized the marketing of a cannabis-derived drug.
Epidiolex may be prescribed for two syndromes affecting children from 2 years of age, which can cause epileptic seizures: Lennox-Gastaut syndrome and Dravet syndrome.
Cannabis is still illegal in the United States at the federal level, although it has been locally authorized by more than half of the states for therapeutic use, and by nine states, including California and Colorado, for recreational use.
