Rather than focusing solely on carbon emissions, chemical engineers at Texas A&M are emphasizing the idea of circularity, where CO2 becomes a resource.

White sharks exhibit stark differences between the DNA in their nuclei and the DNA in their mitochondria, and the longstanding theory that explains why has just been invalidated. 

About 56 million years ago, when Earth experienced a dramatic rise in global temperatures, one meat-eating mammal responded in a surprising way: It started eating more bones.

That’s the conclusion reached by a Rutgers-led team of researchers, whose recent study of fossil teeth from the extinct predator Dissacus praenuntius reveals how animals adapted to a period of extreme climate change known as the Paleocene–Eocene Thermal Maximum (PETM). The findings, published in the journal Palaeogeography, Palaeoclimatology, Palaeoecology, could help scientists predict how today’s wildlife might respond to modern global warming.
