Colossal hatches 26 chicks from artificial eggs in scientific alchemy

Key points

• Colossal Biosciences announced that it has successfully hatched 26 healthy chicks using a fully artificial egg system designed to mimic the functions of a natural eggshell.
• The Dallas-based de-extinction company said the achievement marks a foundational milestone in its long-term effort to resurrect extinct species, including the South Island giant moa and the Dodo.
• At the heart of the breakthrough is a specially engineered “artificial egg” made using a silicone-based membrane enclosed inside a rigid support structure.
• The membrane acts like a biological eggshell, allowing oxygen to pass through while retaining moisture and preventing contamination.
• Read Full Story According to Colossal Chief Biology Officer Andrew Pask, replicating the breathing function of a natural eggshell was one of the biggest scientific challenges.
