The shell is made up of calcium carbonate crystals. The arrangement of these crystals allows the eggshell of a chicken to resist a force of about 40 Newtons (equivalent to 4 kg, or 8.8 pounds of ...

The pigment deposited in the shell happens late in the shell formation process, which is why even when you crack a colored egg, the inside remains white. (Laura McKenzie/Texas A&M AgriLife) ...

Despite their similar appearance to nautilus shells, the egg cases of these pelagic octopuses are made with different genes.

If you've ever cracked open eggs to find spots of blood or meat in it, you are probably wondering what those are. And, more importantly, if they're safe to eat.

The toughness comes from the egg shell's structure; it is made up mostly of calcium carbonate (calcite) crystals, similar to tooth enamel or sea shells, embedded within a protein matrix.

(PhysOrg.com) -- Researchers at the University of Warwick and the University of Sheffield have applied computing power to crack a problem in egg shell formation. The work may also give a partial ...

The evolution of the amniotic egg—complete with membrane and shell—was key to vertebrates leaving the oceans and colonizing the land and air. Now, 360 million years later, bird eggs come in ...

The study is important, scientists say, because it documents for the first time the links among shell formation rate, available energy, and sensitivity to acidification.

Have you noticed you're getting bits of shell in the bowl more often lately when you crack an egg? It's a real thing. Two experts told me why.

As quoted in a game commission post, here are some fun facts about wild bird eggs! In birds, eggshell production takes place mainly at night. Up to 10% of the calcium used for shell formation can ...
