Marine biogenic calcification is the production of calcium carbonate by organisms in the global ocean.. Marine biogenic calcification is the biologically mediated process by which marine organisms produce and deposit calcium carbonate minerals to form skeletal structures or hard tissues.
Earth building applications must protect from all forms of plastic degradation (i.e. heat, light, friction, fire, etc.). [9] Earth building methods ensure that the blocks can be extricated undamaged from the construction when it comes to its end. Earth building methods also ensure that the construction process remains carbon-neutral. [10] [11]
Bone, antler, horn, and ivory objects can be fastened to the mounts through the application of wires or flat acrylic plastic clips. However, metals that come into direct contact with these organic objects can cause damage. The fats that may remain in these organic items react with metal, forming corrosion products that will stain the objects.

Scientists studying her remains have painstakingly pieced together her skull from 200 bone fragments, a process that took nine months. They used the contours of the face and skull to guide a ...
The hierarchical structural of bone spans across to a three tiered hierarchy of the collagen molecule itself. [14] Different sources report different numbers of hierarchical level in bone, which is a complex biological material. [1] [2] [16] The types of mechanisms that operate at different structural length scales are yet to be properly ...
The global theme for Earth Day on Monday is planet vs. plastic. Plastic production continues to ramp up globally and is projected to triple by 2050 if nothing changes. Most of it is made from ...
