UCSD computer scientist wins Young Investigator Award, research on snake venom proteins highlighted
...er proteins and, perhaps, let scientists dive into dinosaur genetics. Modified snake venom proteins have been used in the past to create blood thickening and thinning drugs and powerful pain killers -- but there is much more to learn about proteins from snake venom and Bandeira's research provides a new an...Shoulder ligament a linchpin in the evolution of flight
