The secret about human evolution found in spit

Genetic detectives discover surprising findings about our evolution by studying saliva. |SOURCE| What does a protein in our spit called MUC7 that all of us have – but most of us have never heard of – have to do with human history? A surprising amount, as a recent paper by Xu et al. has discovered. Despite being a rather obscure protein to most of [...] Read more

Fossil footprints challenge established theories of human evolution

Newly discovered human-like footprints from Crete may put the established narrative of early human evolution to the test. The footprints are approximately 5.7 million years old and were made at a time when previous research puts our ancestors in Africa - with ape-like feet. |SOURCE| Ever since the discovery of fossils of Australopithecus in South [...] Read more

Electronic devices that can degrade and physically disappear on demand

A team of researchers from the U.S. and China has demonstrated electronic devices that can degrade and disappear on demand using nothing but moisture in the air. In their paper published on the open access site Science Advances, the team describes their devices and offers ideas on applications that could benefit from them. |SOURCE| Most people [...] Read more

Weird fish fossil changes the story of how we moved onto land

|SOURCE| The evolutionary story we have written to explain our ancestors’ move from sea to land may need a rethink. A fossil fish from this era has been discovered with several of the features of land animals – yet it was only distantly related to them. Roughly 360 million years ago, one group of lobe-finned fish began evolving into four-legged, [...] Read more
