Scientists make stretchy electronics from rubbery materials

|SOURCE| Using rubbery materials, scientists at the University of Houston have successfully created a new form of stretchable electronics that holds promise in health monitors, medical implants and artificial skins. In a paper published this week in the journal Science Advances, the researchers described "a completely new strategy" to develop [...] Read more

Bacteria Use Brainlike Bursts of Electricity to Communicate

With electrical signals, cells can organize themselves into complex societies and negotiate with other colonies. |SOURCE| Bacteria have an unfortunate—and inaccurate—public image as isolated cells twiddling about on microscope slides. The more that scientists learn about bacteria, however, the more they see that this hermitlike reputation is [...] Read more

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
