I once had the pleasure of visiting David Lambert, an expert and pioneer in ancient DNA studies. With Dave I had some of the most interesting and thought provoking discussion about biology, that I have ever had.
Now Dave and his colleagues have a new review out in TREE on New developments in ancient genomics that I can’t wait to read when I get back to work next week.
Here is the abstract:
Ancient DNA research is on the crest of a ‘third wave’ of progress due to the introduction of a new generation of DNA sequencing technologies. Here we review the advantages and disadvantages of the four new DNA sequencers that are becoming available to researchers. These machines now allow the recovery of orders of magnitude more DNA sequence data, albeit as short sequence reads. Hence, the potential reassembly of complete ancient genomes seems imminent, and when used to screen libraries of ancient sequences, these methods are cost effective. This new wealth of data is also likely to herald investigations into the functional properties of extinct genes and gene complexes and will improve our understanding of the biological basis of extinct phenotypes.
PolITiGenomics have posted some details about the upcoming update to the 454 system.
According to the blog, the next upgrade will be called Titanium and will have twice the number of cycles increasing the average read length from 250 to around 400 bases. Furthermore, the new version will have smaller, more densely packed wells on the picotiter plate which will increases the number of DNA fragments sequenced per run. All together, 454 FLX Titanium runs will quintuple their data output from 100 Mb to about 500 Mb.
Obviously, the increased data amount will put even more strain on the downstream image- and sequence analyses pipelines.
Invitrogen Corporation and Applera Corporation today announced that their Boards of Directors have approved a definitive merger agreement, under which Invitrogen will acquire all of the outstanding shares of Applera’s Applied Biosystems Group in a cash and stock transaction valued at $6.7 billion.
One of the stated rationales for the merger, is that Invitrogen and Applied Biosystems will be well positioned to compete in rapidly growing markets, such as next generation sequencing.
I am happy to announce that we have just released version 1.0 of our solution for analyzing and visualizing Next Generation Sequencing data: CLC Genomics Workbench
It includes user-friendly, high quality, high speed reference assembly and de novo assembly of Solexa, SOLiD, 454, and Helicos sequencing data, to name a few key features.
Here you can read a lot more and see a few benchmarks:

Everyone here have worked really hard to make this happen and we now look forward to start coding up new features and functionalities for the next version of the software.
Leaders of the 1000 Genomes Project announced today that three firms that have pioneered development of new sequencing technologies have joined the international effort to build the most detailed map to date of human genetic variation as a tool for medical research. The new participants are: 454 Life Sciences/Roche, SOLiDApplied Biosystems and Solexa/Illumina Inc..
The three companies each have agreed to sequence the equivalent of 75 billion DNA bases in the program’s pilot phase, generating the equivalent of 25 human genomes each over the coming year, according to GenomeWeb.
Update: There is a nice piece on this over at the Genetic Future blog
