Colossal Biosciences has developed an artificial eggshell, marking significant progress in efforts to resurrect New Zealand's extinct giant flightless bird, the moa.

A new artificial egg system from Colossal Biosciences paves the way for work to de-extinct the Giant Moa, along with numerous other science applications, the company said

Colossal Biosciences says its artificial egg has de-extinction and conservation potential.

In an early step towards artificial wombs, a biotech company claims it’s developed a “fully artificial” chicken egg.
