Global temperature change attributable to external factors, confirms new study
Researchers at the University of Oxford have confirmed that human activity and other external factors are responsible for the rise in global temperature. While this has been the consensus of the scientific community for a long time, uncertainty remained around how natural ocean-cycles might be influencing global warming over the course of multiple decades. The…

Comet inspires chemistry for making breathable oxygen on Mars

Comet inspires chemistry for making breathable oxygen on Mars
Science fiction stories are chock full of terraforming schemes and oxygen generators for a very good reason -- we humans need molecular oxygen (O2) to breathe, and space is essentially devoid of it. Even on other planets with thick atmospheres, O2 is hard to come by. So, when we explore space, we need to bring our…

Did ancient supernovae prompt human ancestors to walk upright?

Did ancient supernovae prompt human ancestors to walk upright?
Did ancient supernovae induce proto-humans to walk on two legs, eventually resulting in Homo sapiens with hands free to build cathedrals, design rockets and snap iPhone selfies? A paper published today in the Journal of Geology makes the case: Supernovae bombarded Earth with cosmic energy starting as many as 8 million years ago, with a…
