How a bacterial cell recognizes its own DNA
Bacteria have an immune system to fight off invasive viruses called phages. And like any immune system – from single-celled to human – the first challenge of the bacterial immune system is to detect the difference between ‘foreign’ and ‘self.’

New study hints at spontaneous appearance of primordial DNA
The self-organization properties of DNA-like molecular fragments four billion years ago may have guided their own growth into repeating chemical chains long enough to act as a basis for primitive life, says a new study.

A long-standing mystery in membrane traffic solved
Researchers have discovered that NSF unravels a single SNARE complex using one round ATP turnover by tearing the complex with a single burst, contradicting a previous theory that it unwinds in a progressive manner.
