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 by ...

Ancient DNA reveals new branches of the Denisovan family tree

It's widely accepted that anatomically modern humans interbred with their close relatives, the Neanderthals and Denisovans, as they dispersed out of Africa. But a study examining DNA fragments passed down from these ancient ...

New method for mass-producing high-quality DNA molecules

A new method of manufacturing short, single-stranded DNA molecules can solve many of the problems associated with current production methods. The new method, which is described in the scientific periodical Nature Methods, ...

Adapting personal glucose monitors to detect DNA

An inexpensive device used by millions of people with diabetes could be adapted into a home DNA detector that enables individuals to perform home tests for viruses and bacteria in human body fluids, in food and in other substances, ...

Researchers produce first map of New York City subway system microbes

The microbes that call the New York City subway system home are mostly harmless, but include samples of disease-causing bacteria that are resistant to drugs—and even DNA fragments associated with anthrax and Bubonic plague—according ...
