#40 Extinction Risks, Ocean Water and Assisted Procreation

Discover 3 science news from the latest 24 hours in our #PeerusWhatsNew, now on Medium.

1 A third of Australia’s endangered species are not being watched. Scientists are warning about this major extinction risk.

The Threatened Species Recovery Hub conducted the first national survey on the monitoring of threatened birds, mammals, frogs, freshwater fish and reptiles. A total of 217 species are not followed.

“This puts these species at risk” because researchers do not know if populations are increasing or decreasing, the reasons for the changes and the measures that should be put in place.

2 Two planetologists have just added a new element to the debate about the origin of ocean water on Earth and indirectly on the Moon.

The two questions are linked to a common origin of these two stars, revealed by the Apollo missions and which led to the famous hypothesis of the collision between our blue planet and the planet Theia.

The water would vaporize upon the impact, but it would be partly recaptured by some of the melt generated by it. Part of the water from the Earth and the Moon may well have been brought by asteroids, when they were very young.

3 The assisted procreation dominated the debates of the Estates General of Bioethics, whose consultation phase ended Monday night.

Among the nine themes, “Procreation and society” is the one that has most mobilized the public, before another societal issue, the end of life.

According to CCNE, the site attracted 183,500 unique visitors and 29,000 participants, who sent 65,000 concrete proposals. 45% of these contributions were related to “Procreation and Society”.
