\'Lost\' letters reveal twists in discovery of double helix

A twist of discoveryMany have argued that Franklin deserved Nobel recognition, because her experimental work revealed the double-helix structure that helped Crick and Watson build their DNA model. Even Watson suggested much later that Franklin and Wilkins should have shared a Nobel Prize in chemistry for their contributions. Franklin, who had all the photographic evidence of DNA’s double-helix structure in front of her, had dismissed the idea of a helix. That’s because she focused her attention on the clearer data from the A form of DNA, which looks less obviously like a helix than the B [more...]

Synthetic Biology: Building Life (Potential & Dangers ...

But today, applications of our understanding of DNA in areas such as genetic engineering and cloning seem primitive compared to synthetic biology, a field in which the basic building blocks of life are pieced together from scratch to suit the needs of research, medicine, and the environment. Synthetic biology combines knowledge of genetics and cell biology with principles of engineering and is limited only by scientists’ imaginations.  But the field is still in its infancy, and initial ventures into figuring out how best to put the basic components of DNA together synthetically have [more...]

Popular Mechanics Posts 2010 BREAKTHROUGH Awards — The Gadgeteer

While working at the National Institutes of Health in the early 1990s, Venter developed a way to rapidly discover genes by exploiting snippets of DNA called expressed sequence tags. In 1992, he founded The Institute for Genomic Research, and, three years later, he and a team decoded the first genome of a free-living organism. That led to Venter’s best-known breakthrough, mapping the human genome. Last May, he achieved a defining moment in the history of biology when he inserted digitally created DNA into a living bacterium, forming the first synthetic life. His ultimate goal is to design [more...]

OfficialWire: North American Biometrics Market - New Market Report ...

Unique technologies such as brain fingerprinting, DNA fingerprinting, and skin printing are poised to propel the market forward in the long term. Although the outlook for the market is bright, there are some impediments slowing its momentum. The economic slowdown had cast a shadow over the market, and the financial and consumer sectors felt its impact the most. In the government sector, projects were delayed; however, there were few cancellations. Government-backed projects typically have long sales cycles and can sometimes stretch over a year before completion, depending on the complexity [more...]

DNA database quango calls for greater transparency | Kable

The National DNA Database Ethics Group has said there needs to be an auditable process for databases used in parallel with the National DNA Database In its annual report 2009-2010, the group says it will explore what steps are necessary to regularise police databases that run alongside the DNA Database. They include systems holding information relevant to counter terrorism, missing persons and contamination elimination. "Their purposes need to be clearly defined, with robust oversight and standards in place. They also need to be transparent. The existence of these databases raises a risk of [more...]

Rivalry Among DNA Sleuths Comes Alive in Letters - 3quarksdaily

The letters were written during a 26-year period when Crick informally guided the progress of molecular biologists around the world in establishing how DNA operates in living cells. An article on the letters was published Wednesday in the journal Nature, focusing on those related to the discovery of DNA’s double helix structure in 1953. “We are really between forces that may grind all of us to pieces,” the physicist Maurice Wilkins wrote after a disastrous attempt by Crick and his colleague James D. Watson to build a model of DNA based in part on data gathered by Rosalind Franklin. [more...]

Beautiful Minds: Primate Productivity | The Guardian

“Pascal is a very creative individual, not only in coming up with experiments to test his hypothesis, but also in the ways in which he illustrates them,” she said. “He builds models — sometimes huge, sometimes small, always interesting.” Gagneux earned his masters in population biology and his doctorate on population genetics from Basel University in Switzerland. He has been studying the population genetics of West African chimpanzees since he came to UCSD as a graduate student 17 years ago. He was drawn to the school in part by Professor David Woodruff, who pioneered a method of [more...]
