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.”

jimsnail writes “J. Craig Venter and the Institute that bears his name are again moving into new territory in the field of genetics. Genetic patents, that is. They are seeking a broad patent that would give them ownership of a ‘free living organism that can grow and replicate’ constructed entirely from synthetic DNA. The ETC Group is challenging the claim. ‘Scientists at the institute designed the bacterium to have a “minimal genome”–the smallest set of genes any organism can live on. The project, which began in the early 2000s, was partly a philosophical exercise: to help define life itself better by identifying its bare-bones requirements. But it was also fraught with commercial possibilities: if one could reliably recreate a standardized, minimal life form, other useful genes could be added in as needed for various purposes.’”

anik315 writes “Nature is reporting a major breakthrough in embryonic stem cell research. A straightforward procedure using mouse fibroblasts harvested from the skin can be used to produce pluripotent stem cells that can potentially become any other cell in the body. Not only can Yamanaka’s method use the most basic cells, it can be accomplished with simple lab techniques. Possible applications of this breakthrough are to check molecular changes in cells as certain conditions develop. Stem cells produced using this procedure, however, can not be use to safely to make genetically matched cells for transplant.”

Killam0n takes note of a story in CNN Money on progress in controlling computers via brainwaves. From an aspirin-sized implant a quadriplegic is now using to play computer games, the article extrapolates out to a near future in which we will all be wearing headband computers and IM’ing one another as if telepathically. “Two years ago, a quadriplegic man started playing video games using his brain as a controller. That may just sound like fun and games for the unfortunate, but really, it spells the beginning of a radical change in how we interact with computers — and business will never be the same. Someday, keyboards and computer mice will be remembered only as medieval-style torture devices for the wrists. All work — emails, spreadsheets, and Google searches — will be performed by mind control.”

innocent_white_lamb writes “A member of the Canadian Parliament has proposed legislation to outlaw the development and deployment of ‘terminator genes’ that would prevent seeds from germinating after a set span of time. This practice would require farmers to re-purchase seed every year instead of saving the seeds from last year’s crop. The legislation is not expected to pass due to opposition from the Agriculture Minister. ‘There is also an issue with the technology, which is based on a complicated five-gene construct. It is “inevitable” it will fail and could harm biodiversity, said Lucy Sharratt, co-ordinator of the Canadian Biotechnology Action Network, which backs the ban. CFIA argues exactly the opposite, saying “the terminator approach provides an excellent method to protect against transference of novel traits to other crops and plant species.”‘”

unchiujar writes “The New York Times reports that the full genome of James D. Watson, one of the discoverers of the structure of DNA in 1953, has been deciphered, marking what some scientists believe is the gateway to an impending era of personalized genomic medicine. A copy of his genome, recorded on a pair of DVDs, was presented to Dr. Watson on Thursday in a ceremony in Houston by Richard Gibbs, director of the Human Genome Sequencing Center at the Baylor College of Medicine, and by Jonathan Rothberg, founder of the company 454 Life Sciences. ‘The first two genome sequences belonging to individuals are now being made available to researchers within a few days of each other. One is Dr. Watson’s and the other belongs to J. Craig Venter, who as president of the Celera Corporation started a human genome project in competition with the government. Dr. Venter left Celera [...]
