Unexpected Source for the Brain's Development

Reminds me  of the "Junk DNA" controversy.  Just because the purpose of something is not immediately apparent doesn't necessarily mean it is junk.  So-called "junk" may contain Hidden Treasures.







Glia were completely overlooked until it was discovered that Einstein's brain was packed with them...

Babylonians beat Greeks to the Invention of Trigonometry


It used to be the standard notion that the Babylonians just employed rules of thumb based on trial and error, but modern research continues to reveal more and more about how the Babylonians rather than the Greeks pioneered much modern mathematics. Read about how the Babylonians beat the Greeks to the invention of trigonometry...
