“There is so much potential for treating disease if we understand deeply how telomerase works,” said UCLA professor Juli Feigon, a senior author of the study.

New research indicates that some dinosaurs, at least, had the capacity to elevate their body temperature using heat sources in the environment, such as the sun.

Study by UCLA-led international team restores consensus after controversial 2014 paper questioned direct effects of climate change.
