Il semble que le sommeil humain soit un vrai casse-tête. Un article parle de la façon dont l'air sous pression pourrait aider. En gros, on respire depuis qu'on est né, et si on arrête, c'est fini assez vite. C'est un peu ennuyeux comme sujet, mais bon, qui sait ? Peut-être que ça fonctionnera. Les gens cherchent toujours des solutions pour mieux dormir. Pas vraiment passionnant, mais ça existe. #sommeil #respiration #air #pression #santé

Depuis quelques mois, il est fréquent que des robots appellent des particuliers à la place d’humains, pour faire du démarchage téléphonique. Même si ces « voice bots » vendus par des start-up d’intelligence artificiellesont encore peu répandus dans les entreprises, selon le dernier baromètre annuel réalisé par EY pour le syndicat des professionnels des centres de contact, le secteur, qui emploie 290 000 personnes, a vu une « accélération généralisée du recours aux technologies basées sur l’intelligence artificielle » en 2023 et 2024. Après la numérisation, qui a permis de déléguer une partie des tâches au client, puis les délocalisations, l’IA s’ajoute à une double tendance négative. « Depuis dix-huit mois, il y a un gel des recrutements, car les employeurs prévoient une baisse des demandes clients, décrit Caroline Adam, déléguée générale du SP2C. Il y a une réelle inquiétude sur l’IA, mais on manque de recul pour y répondre. » Lire aussi | L’Assemblée nationale interdit le démarchage téléphonique sans « consentement » Les entreprises ont déjà mis en œuvre un certain nombre de cas d’usage. Chez Engie, les comptes rendus que devaient rédiger les conseillers après chaque appel ont été supprimés il y a quelques mois : désormais, une IA générativerésume l’appel en cinq lignes, et le texte est soumis à validation par le conseiller. Mais l’entreprise a tenu à ne pas réduire le temps entre deux appels, pour préserver cette « respiration ». « L’IA est un copilote de nos conseillers, explique Jean-Rémy Dudragne, directeur expérience client d’Engie. On a aussi une IAG qui propose des brouillons de réponse à des questions posées par des clients par e-mail. » « Peur en Bourse » Chez Konecta, qui prône un modèle hybride entre humain et machine, une IA reformule les mails trop longs des clients, et propose même de les rendre moins agressifs. Elle suggère aussi des réponses types aux salariés. Du côté de Teleperformance, « pour l’instant, l’IA est utilisée à pas comptés, de façon moins intensive que ce qui était prévu au départ, car l’annonce pardirection qu’il y aurait encore moins de contacts téléphoniques a fait peur en Bourse, explique Issam Baouafi, délégué syndical Sud.

Mosura fentoni belongs to an extinct group of early arthropods.

Despite centuries of digging, paleontologists are still unearthing new flora and fauna preserved for millennia in rocks. Case in point, the newly discovered Mosura fentoni. This 506-million-year-old predator was found in Canada’s Burgess Shale and packed a punch for something only about the size of a human index finger. The findings are detailed in a study published May 13 in the journal Royal Society Open Science. Meet Mosura From the fossils, paleontologists believe that Mosura fentoni had three eyes, spiny jointed claws, a circular mouth lined with teeth, and a body equipped with swimming flaps along its sides. It was likely part of an extinct group of small early arthropods called radiodonts. The three-feet-long predator Anomalocaris canadensis was also a radiodont that shared the water with Mosura. However, Mosura has something that has not been seen in other radiodont. It has an abdomen-like body region made up of several segments at its back–similar to living insects and other arthropods.  Life reconstruction of Mosura fentoni.

The sea moth Field collectors nicknamed Mosura the “sea-moth” due to the board swimming flaps located near its midsection and narrow abdomen. The moth-like feature inspired its scientific name, which references the fictional Japanese kaiju also known as Mothra. However, it is only distantly related to real moths. Mosura sits on a much deeper branch in the arthropod evolutionary tree. “Radiodonts were the first group of arthropods to branch out in the evolutionary tree, so they provide key insight into ancestral traits for the entire group,” Jean-Bernard Caron, a study coauthor and Curator of Invertebrate Palaeontology at the Royal Ontario Museum, said in a statement. “The new species emphasizes that these early arthropods were already surprisingly diverse and were adapting in a comparable way to their distant modern relatives.” Fossil specimen of Mosura fentoni, ROMIP 67520 from the Marble Canyon area.

We can see traces representing bundles of nerves in the eyes that would have been involved in image processing, just like in living arthropods. The details are astounding,” said Caron.  Open blood Instead of having internal arteries and veins to transfer blood the way that most living mammals do, Mosura had an open circulatory system. Its heart pumped blood into large internal body cavities called lacunae. In some of the fossils, the lacunae are preserved as reflective patches that fill the body and extend into the swimming flaps. “The well-preserved lacunae of the circulatory system in Mosura help us to interpret similar, but less clear features that we’ve seen before in other fossils. Their identity has been controversial,” said Moysiuk. “It turns out that preservation of these structures is widespread, confirming the ancient origin of this type of circulatory system.” Anatomical diagram of Mosura fentoni, showing preserved details of the nervous system in purple, the digestive system in green, and the circulatory system in orange.

If you think you’ve seen it all before, you just need to open up a museum drawer,” said Moysiuk.
