The scientific news for May 9, 2022 is:
In fauna: Six new species of cryptic mini frogs have been discovered in Mexico.
- Thumbnail size discovered in the forests of Mexico. One of them has a length of 13 millimeters, which is even the smallest in the country.
- These self-growing egg frogs appear as perfect miniature frogs, unlike the majority that hatch like tadpoles.
- According to Tom Jameson, a zoologist at the University of Cambridge, “This new species has gone unnoticed, because it is small, brown and very similar to other frogs“.
In kind: the launch of the COP15 conference to combat desertification in Abidjan in the face of “emergency”.
- Participants in COP15, which runs until May 20, will try to propose concrete measures to halt the increase in desertification.

- In this clinical trial, a team from Yale University in the US noted that a third of the 1,200 patients in their study had a significant response to treatment.
In animals: cuckoos are threatened by the genetic defenses of birds that parasitize them.
- An Anglo-South African team has just shown that the viability of birds that parasitize the nest of other species is transmitted only by mothers. Genetic peculiarity can play a dirty trick on our cuckoo clocks.
- Relationships between different species of parasitic birds and the hosts forced to raise their offspring date back at least two million years.
- Researchers argue that “Some parasitic species have developed an amazing range of egg colours, which helps them distinguish parasite eggs from their own.”
Healthy: interview. “The obstacles to advancing AI in medicine are more human than technical.”
- Bernard Nordlinger, co-editor of the book Medicine and artificial intelligenceannounces that the development of artificial intelligence in medicine will revolutionize this environment in the coming years.
- According to him, he can10 or 15 years from the time when the use of AI will be effective. It allows you to manage huge amounts of data more efficiently than a human, provided you know how to use it“.
- So it indicates the needThat clinicians agree to train AI as an aid in their daily practice, without fear of depriving them of their work.”
