The scanning tunnelling microscope can image and distinguish individual bases in DNA molecules, thus allowing partial sequencing of the strands. Obtaining the sequence of the four bases in DNA ...

In Helicos Biosciences’ method, individual DNA strands extracted from cells are sequenced by iterative cycles of base addition. Credit: Helicos Biosciences The first human genome sequence cost more ...

What if you could put a few bacterial cells into a USB stick, plug it into your laptop, and get back a complete DNA sequence in a matter of minutes? Oxford Nanopore has built a USB device that will do ...

Even as species diverge, they retain some common genomic elements, perhaps none as stubbornly constant as ultraconserved elements (UCEs). UCEs tend to consist of fairly lengthy stretches of DNA, ...

A team of experts in ancient DNA from McMaster University (Canada) and genome researchers from Penn State University (USA) have obtained the first genomic sequences from a woolly mammoth, a mammal ...

Researchers in Egypt have developed a technique to compress DNA sequences of the kind used in medical research so that they take up a lot less space in a computer database but without loss of ...

All the cells in an organism have the exact same genetic sequence. What differs across cell types is their epigenetics -meticulously placed chemical tags that influence which genes are expressed in ...

This radical new method could preserve our entire knowledge base for thousands of years, in a storage medium the size of a ...
