This Adorable Bird Is Apparently a Vicious Brain-Eating Zombie in Disguise

The Great tit might seem like just a cute little bird, but don’t let its appearance fool you for. In reality, it is one of the most vicious creatures in the world. Also known as ‘The Zombie tit’, this chirping ball of feathers is a killing machine with an insatiable hunger for brains.
Scientists generally agree that modern birds are direct descendants of fierce dinosaurs like the T-Rex and Velociraptor. Of course, most of them are so small and their feathers so pretty that it’s hard for people to actually associate them with the monstrous creatures depicted in films like Jurassic Park. However, their predatory instincts have definitely passed the test of time, and this holds true for the tiny Great tit, as well. So what’s so scary about this seemingly harmless bird? Well, just that it is known to routinely seek out other birds and bats, crush their heads and feast on their brains!

Why is Roman concrete so durable?

Volcanic ash, of course.

and what is even better, it's "green":

 “If we can find ways to incorporate a substantial volumetric component of volcanic rock in the production of specialty concretes, we could greatly reduce the carbon emissions associated with their production and also improve their durability and mechanical resistance over time,” explained Marie Jackson of the University of California, Berkeley.
