... basement and the hospital down the street does CT scans
for you, you get calls from researchers around the world. Especially when your computer can handle 3-D photos and you can send digital images over the Internet. That's what Jack and Celeste Horner have found at the Museum of the Rockies at Montana St...
Blood test for diagnosing schizophrenia
