Melting Glaciers, Iceland: Land that had been covered in ice since before 1550 is now being revealed. Melting glacial ice is freeing volcanic magma from deep below the ground, and as ice sheets continue to shrink, scientists believe that we will see more eruptions in Alaska, Patagonia, and Antarctica.
In vertebrates, the eyeballs are direct extensions of the brain; that is, they evolved after the brain, and are literally unimpeded access to the cerebellum and cerebrum. Because of this, many ocular tumors or injuries can be far more dangerous to the brain than growths or injuries on any other part of the skull.
