The mystery of why birds’ eggs come in so many shapes has long been up in the air. Now new research suggests adaptations for flight may have helped shape the orbs. Stronger fliers tend to lay more ...

The unusually long, oval egg of the Indonesian maleo may look a lot like a potato, but this bird is no slouch. When the chicks of these anvil-headed animals hatch, they're almost immediately able to ...

The eggs laid by birds come in an astonishing variety of shapes: ellipses in hummingbirds, spheres in owls, pointy ovoids in shorebirds and almost everything in between. Avian egg shape has fascinated ...

Researchers have discovered a universal mathematical formula that can describe any bird's egg existing in nature -- a significant step in understanding not only the egg shape itself, but also how and ...

The shape of the universe has been puzzling scientists for decades, and some new theories suggest it might not be the flat or spherical shape we’ve assumed, but something far more egg-like. While ...

Eggs is eggs, but some are round while others are long and pointy – and now we finally know why. It’s all to do with birds’ flying ability, according to a new study. There are many explanations for ...

Mathematical descriptions of all basic egg shapes have already found applications in food research, mechanical engineering, agriculture, biosciences, architecture and aeronautics. As an example, this ...
