Ice core 'dipstick' indicates West Antarctic ice has thinned less than believed

Alleged 40,000-year-old human footprints in Mexico much, much older than thought

Its dating techniques returned a date of 40,000 years ago, in contrast to the oldest accepted human fossil from the Americas, an 11,500-year-old skull. This makes the rock "one of the most important areas ...
