Wanted: A better way to decipher DNA mutations

dianeb — Wed, 09 Sep 2009 14:24:10 -0600

Single DNA mutations can make the difference between robust health and debilitating illness, but how do we know which mutations are which? Current tests aren't very reliable, but ASU scientists are helping find better ways to decipher our genetic codes. --by Richard Harth

Ants more rational than humans

Whales not to blame for dwindling fish populations

pkrecker — Mon, 02 Mar 2009 11:51:23 -0700

For decades there has been a controversy about whales eating fish in the tropics. The debate has been at the heart of policy decisions about the culling of whales and is pivotal to the future of commercial whaling in the region. New research, however, shows that culling whales in an attempt to restore fish populations is not scientifically sound. --by Margaret Coulombe

Early humans had jaws of steel
