The journal Science tomorrow will feature the discovery of the oldest human skeleton. Ardi, or more formally Ardipithecus ramidus, lived in Ethiopia 4.4 million years ago. She is therefore over a million years older than the famous "Lucy" fossil, found in the same region thirty-five years ago.

On May 28, 2009, the Texas State Senate rejected Don McLeroy as chairman of the State Board of Education. The Senate voted 19-11 to approve McLeroy, failing meet the 2/3 majority needed. The vote fell along party lines, with the 19 Republicans approving him and 11 of the 12 Democrats rejecting him (one Democrat abstained).
