- A Nature poll of 1,000 biomedical scientists reveals that 90 percent believe animal research is essential for science, but that 30 percent know someone who has been negatively affected by animal rights protests. Of the thousand, 54 “said that they had actually changed the direction of their research as a result of misgivings about their research practices.”
- A dental clue to climate: Horse teeth from millions of years ago can help scientists reconstruct what plant life was like and how it would have changed, because horses’ teeth would have evolved with their changing diet.
