Molecular analysis of the eggshell structure of large flightless birds such as ostriches and emus provides new insights into how they evolved. Genetic analyses have recently allowed scientists to ...

We present the first comprehensive multiscale characterization of domestic pigeon Columba livia eggshells. It is a sustainable by-product of low-input poultry farming, which is important for rural ...

Over their short lifetimes though, bird eggshells change their strength. For example, they get thinner and weaker before hatching begins. Now, researchers investigating eggshell structure have zeroed ...
