Targeting Breast Cancer and Metastases with a Combination of LHRH and Lytic Peptide, Hecate, bound to Iron Oxide Nanoparticles (Abstract 3280) Researchers have combined a hormone, a cell-killing peptide and nanoparticles to both tar...

Skull study sheds light on dinosaur diversity

...in North America during the middle of the dinosaur era but were thought to have been pushed to extinction by more specialized plant-eaters at the end of that era. New discoveries, however, are showing that one lineage of sauropods diversified at the end of the dinosaur era, University of Michigan paleont...

Proposal would allow wild animals to roam North America

...Great Plains and Southwest. During the Pleistocene era -- between 1.8 million to about 10,000 years ago -- North America's ecosystems were much more diverse. As animals became extinct, many gaps developed in the web of interactions that makes up a healthy ecosystem. Introducing living counterparts to the...
