A biological switch that reliably turns protein expression on at will has been invented by University of Bath and Cardiff University scientists.  Now, in a new paper published in Nature Structural & Molecular Biology, Mayo researchers have determined how one DNA repair protein gets to the site of DNA damage.  A microscopic thread of DNA evidence in a public genealogy database led California authorities to declare this spring they had caught the Golden State Killer, the rapist and murderer who had eluded authorities for decades.  Researchers at Delft University of Technology, in collaboration with colleagues at the Autonomous University of Madrid, have created an artificial DNA blueprint for the replication of DNA in a cell-like structure.  An LMU team now reveals the inner workings of a molecular motor made of proteins which packs and unpacks DNA.  Chemist Ivan Huc finds the inspiration for his work in the molecular principles that underlie biological systems.  What makes particles self-assemble into complex biological structures?  Scientists from Moscow State University (MSU) working with an international team of researchers have identified the structure of one of the key regions of telomerase—a so-called "cellular immortality" ribonucleoprotein.  Researchers from Tokyo Metropolitan University used a light-sensitive iridium-palladium catalyst to make "sequential" polymers, using visible light to change how building blocks are combined into polymer chains.  Researchers have fused living and non-living cells for the first time in a way that allows them to work together, paving the way for new applications.  UZH researchers have discovered a previously unknown way in which proteins interact with one another and cells organize themselves.
