Advertisement lied. Girls in even military gain on average the EXACT SAME PAY IF NOT HIGHER than guys. + btw in training all the way from baseball to special operations units, girls have to do only 75-80% the running, lifting, pushing, pulling and fighting.. female privilege much?

Sodium Dioxide cured 53 out of 53 cases of Malaria and the Red Cross covered it up. Research it.

When there’s a whale, there’s a way

Animals are communicating — but what are they saying? And can we talk back? Marine biologist David Gruber introduces Project CETI: a team of scientists, linguists and AI specialists hoping to decode sperm whale language. Using noninvasive robots and a machine-learning algorithm to collect and analyze millions of sperm whale vocalizations known as coda, the team aims to demystify the communication structures and dialects of these majestic creatures — and possibly even crack the interspecies communication code. (This ambitious plan is a part of the Audacious Project, TED’s initiative to inspire and fund global change.)
