Genes that separate humans from fruit flies found

|SOURCE| Genes which determine animal complexity – or what makes humans so much more complex than a fruit fly or a sea urchin – have been identified for the first time. The secret mechanism for how a cell in one animal can be significantly more complex than a similar cell in another animal appears to be due to proteins and their ability to control [...] Read more

Sonochemical Synthesis: Did Life Originate Inside Collapsing Bubbles?

|SOURCE| The origin of life is a profound mystery. Once life arose, natural selection and evolution took over, but the question of how a mixture of various gases created life-giving molecules that arranged into structures capable of reproducing themselves remains unanswered. Many theories have been proposed, some of which are popular (e.g., RNA [...] Read more

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
