Colossal développe une coquille d'œuf artificielle pour favoriser le retour du moa

La société Colossal Biosciences affirme avoir créé une coquille d'œuf artificielle qui pourrait aider à produire des œufs de la taille de ceux pondus autrefois par le moa, une espèce éteinte de Nouvelle-Zélande. Des experts indépendants avertissent que cette avancée est encore loin de permettre le retour de ces oiseaux géants.

L'entreprise, qui avait précédemment prétendu avoir ressuscité le loup terrible par édition génique, a dévoilé une structure en treillis supportant une membrane en silicone transparente. Cette membrane permettrait une circulation d'oxygène à des taux similaires à ceux d'une coquille d'œuf de poule naturelle, sans nécessiter d'apport supplémentaire en oxygène. Les moas mesuraient plus de trois mètres de haut et pesaient plus de 200 kilogrammes, avec des œufs atteignant 24 centimètres de longueur et 18 centimètres de largeur.

A mother-and-daughter duo of citizen scientists has uncovered the largest known coral colony on Australia's Great Barrier Reef, measuring 111 meters across and covering nearly 4,000 square meters. The J-shaped formation of Pavona clavus was found during a dive as part of the Great Reef Census initiative. Advanced 3D modeling confirmed its size, highlighting the role of community involvement in marine conservation.

A 250-million-year-old fossil egg containing a Lystrosaurus embryo has provided the first direct evidence that mammal ancestors laid eggs. Discovered in South Africa, the find resolves a decades-old question about early mammalian reproduction following the End-Permian extinction. Researchers used advanced imaging to reveal the embryo's pre-hatching stage inside a soft-shelled egg.

Taiwanese researchers built a life-size model of an oviraptor nest to investigate how these dinosaurs incubated their eggs. Their experiments indicate a hybrid method involving parental warmth and sunlight, differing from modern birds. This approach explains uneven heating and asynchronous hatching in nests.

On Saturday morning, the eagle owl pair's eggs began hatching at Falun mine in Dalarna. Thousands of enthusiasts have followed the nesting via social media for weeks. The first fluffy chicks appeared in Stora stöten.

The study, published in Nature, analyzed natural Sydney rock oyster reefs and tested artificial designs in local estuaries. Findings emphasize small protected spaces over complex structures.

Researchers at Lund University in Sweden have created a cell-free cartilage scaffold that guides the body to repair damaged bone. The innovation, tested successfully in animal models, avoids strong immune reactions and offers a universal alternative to patient-specific grafts. Plans are underway to test it in human clinical trials.
