Fossil dating method points to earlier human emergence Humans were likely around about 36,000 years earlier than previously though. Researchers calculated the age of fossils found in Africa using the single crystal argon-argon dating method, analyzing pumice and ash left […]
Any person with some basic knowledge of chemistry is familiar with the concept of electrolysis, i.e., the production of a chemical reaction by passing an electric current through an electrolyte – a liquid that conducts electricity as a result of […]
“The last star will slowly cool and fade away. With its passing, the universe will become once more a void, without light or life or meaning.” So warned the physicist Brian Cox in the recent BBC series Universe. The fading […]
