DNA data storage: 100 million hours of HD video in every cup

Biological systems have been using DNA as an information storage molecule for billions of years. Vast amounts of data can thus be encoded within microscopic volumes, and we carry the proof of this concept in the cells of ...

The first stages of DNA evolution

One fundamental question in the field of the Origin of Life is how the first molecules of DNA replicated and evolved on the primordial Earth, more than 4 billion years ago. Before the emergence of the first cells or any other ...

Sixty-year-old question on DNA replication timing sequence answered

Over the last 60 years, scientists have been able to observe how and when genetic information was replicated, determining the existence a "replication timing program," a process that controls when and in what order segments ...

DNA nanorobots find and tag cellular targets

Researchers at Columbia University Medical Center, working with their collaborators at the Hospital for Special Surgery, have created a fleet of molecular "robots" that can home in on specific human cells and mark them for ...

DNA sequencing improved by slowing down

EPFL scientists have developed a method that improves the accuracy of DNA sequencing up to a thousand times. The method, which uses nanopores to read individual nucleotides, paves the way for better - and cheaper - DNA sequencing.
