Tim O’Reilly has a post about how the prominent scholarly journal Nature has recently launched an open-access service for pre-publication research and presentations. In Nature Precedings, all content is released under a Creative Commons Attribution License, and can be commented and voted on. The service will cover research in biology, chemistry, and earth science, much like arXiv.org does for physics, mathematics, and computer science.

“Human therapeutic cloning has moved a step closer after U.S. researchers said they had successfully created embryonic stem cells from monkey embryos. Scientists told a stem cell research conference in Cairns this week that they had successfully created two batches of embryonic stem cells from cloned rhesus monkey embryos.”

Spamicles writes “For less than $200 and a cheek-swiped cotton swab, you will soon be able to add DNA results to family tree Web sites. Ancestry.com plans to launch the DNA testing product by the end of summer, offering customers the possibility of finding DNA matches in the site’s 24,000 genealogical databases. By taking a simple cheek-swab test and comparing results against DNA profiles in a test-results database, virtually anyone can uncover genealogical associations unimaginable just a few years ago. Users can easily connect with and discover lost or unknown relatives within a few generations, as well as gain insight into where their families originated thousands of years ago.”

bshell writes “An article in science blog says we may have to rethink how genes work. So called “junk DNA” actually appears to be functional. What’s more it works in a mysterious way involving multiple overlaps that seems to be connected in some sort of network.” From the article: “The ENCODE consortium’s major findings include the discovery that the majority of DNA in the human genome is transcribed into functional molecules, called RNA, and that these transcripts extensively overlap one another. This broad pattern of transcription challenges the long-standing view that the human genome consists of a relatively small set of discrete genes, along with a vast amount of so-called junk DNA that is not biologically active. The new data indicates the genome contains very little unused sequences and, in fact, is a complex, interwoven network. In this network, genes are just one of many types of DNA sequences that [...]

gollum123 writes “A major advance in the genetic understanding behind several of the world’s most common diseases is being reported by the BBC. A study tested some 17,000 people to find genetic markers for the various diseases. ‘They found new genetic variants for depression, Crohn’s disease, coronary heart disease, hypertension, rheumatoid arthritis and type 1 and 2 diabetes. The Wellcome Trust Case Control Consortium (WTCCC) involved 50 leading research groups analyzing the DNA from 2,000 patients for each of the seven conditions and 3,000 healthy volunteers. One of the most exciting finds was a previously unknown gene common to type 1 diabetes and Crohn’s disease, a type of inflammatory bowel disorder, suggesting that they share similar biological pathways.’ There is also disease by disease data at the BBC.”
