THE precursor of life may have learned how to copy itself thanks to simple convection at the bottom of the ocean. Lab experiments reveal how DNA replication could have occurred in tiny pores around ...

A molecular illustration of the crowded interior and cell envelope of Escherichia coli. (David S. Goodsell, The Scripps Research Institute) To replicate information, life usually has fairly ...

We tend to think of the DNA strands that contain our genetic code as consistent, stable units. But in reality, the cells that make up our bodies are constantly replicating and changing. Even as you ...

Weizmann Institute of Science and Rowan University researchers show that repair enzymes fail to fix gene structures of certain shapes, in discovery that may lead to new therapies The post Breakthrough ...

Scaffolded DNA and RNA origami is a technique that allows scientists to build tiny, highly precise two- and three-dimensional objects. Because these nanostructures can interact naturally with ...

Healthy brains may be built through a process of controlled damage and rapid repair. The most dangerous type of DNA damage is a regular feature of healthy early brain development, experiments in mice ...
