Coralline Red Algae: Existed 300M Years Longer

Coralline red algae have existed for 130 million years, in other words since the Cretaceous Period, the time of the dinosaurs. At least this was the established view of palaeontologists all over the world until now. However, this classification will now have to be revised after fossils discovered by researchers at GeoZentrum Nordbayern at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) in conjunction with researchers at La Trobe University in Melbourne, Australia, prove that coralline red algae existed as far back as 430 million years ago.

A Lock & Key System To Bind To DNA: Used By Proteins

Scientists have traditionally thought that DNA binding proteins use patterns in the genome's code of As, Cs, Ts, and Gs to guide them to the right location, with a given protein only binding to a specific sequence of letters. In a new study published in Cell Systems, scientists discovered that proteins must rely on another clue to know where to bind: the DNA's three-dimensional shape.
