The evidence that the dodo bird (Raphus Cucullatus), extinct since 1681, could be alive is not quite as solid but still interesting. A night vision video recently uploaded to the Internet shows what appears to be a live dodo walking past an iguana.
Interestingly, hard-boiled eggs do not keep nearly as long as raw eggs, which can last three to five weeks in the refrigerator. There is a good reason for this. When a hen lays an egg, it puts a naturally protective coating on the outside of the shell.
Hard-boiled eggs stay fresh for up to one week in a refrigerator, according to the USDA Food Safety and Inspection Service. Water used for boiling removes the eggs' protective coating, increasing the chance that bacteria enters the shell.
