Scientists unveil tools for rewriting the code of life MIT and Harvard researchers have developed technologies that could be used to rewrite the genetic code of a living cell, allowing them to make large-scale edits to the cell’s genome. Such technology could enable scientists to design cells that build proteins not found in nature, or engineer bacteria that are resistant to any type of viral infection. The technology, described in the July 15 issue of Science, can overwrite specific DNA sequences throughout the genome, similar to the find-and-replace function in word-processing programs. Using this approach, the researchers can make hundreds of targeted edits to the genome of E. coli, apparently without disrupting the cells’ function. “We did get some skepticism from biologists early on,” says Peter Carr, senior research staff at MIT’s Lincoln Laboratory (and formerly of the MIT Media Lab), who is one of the paper’s lead authors. DNA consists of long strings of “letters” that code for specific amino acids. ‘Plug and play’
Twins Every summer, on the first weekend in August, thousands of twins converge on Twinsburg, Ohio, a small town southeast of Cleveland named by identical twin brothers nearly two centuries ago. They come, two by two, for the Twins Days Festival, a three-day marathon of picnics, talent shows, and look-alike contests that has grown into one of the world's largest gatherings of twins. Dave and Don Wolf of Fenton, Michigan, have been coming to the festival for years. "Must be a twins thing," Don says. This afternoon at the festival the brothers have stopped by a research tent sponsored by the FBI, the University of Notre Dame, and West Virginia University. "Although identical twins may look the same to you and me, a digital imaging system can spot minute differences in freckles, skin pores, or the curve of their eyebrows," says Patrick Flynn, a computer scientist from Notre Dame. Because their beards cover half of their faces, the Wolf brothers pose a particular challenge. "I don't hate it.

Nucleus Medical Media: Medical Video, Animation & Illustration Complete Genomics May Be Worth The Gamble I have been following Complete Genomics (GNOM) for a while now. I've even put it in my list of five favorite stocks. I really like its products; I really like its services, and I really like its CEO, Cliff Reid. By all accounts this is a great little company ready to take off like a rocket. Complete Genomics is an early stage biotech company engaged in human DNA sequencing using proprietary machines, process, and analytics. Sequenom (SQNM) and Amarin (AMRN) are two examples of a developmental stage biotechs that missed their quarterly targets but didn't see their stock price take a dive next day.

Mutated DNA Causes No-Fingerprint Disease Almost every person is born with fingerprints, and everyone's are unique. But people with a rare disease known as adermatoglyphia do not have fingerprints from birth. Affecting only four known extended families worldwide, the condition is also called immigration-delay disease, since a lack of fingerprints makes it difficult for people to cross international borders. In an effort to find the cause of the disease, dermatologist Eli Sprecher sequenced the DNA of 16 members of one family with adermatoglyphia in Switzerland . Seven had normal fingerprints, and the other nine did not. After investigating a number of genes to find evidence of mutation, the researchers came up empty-handed—until a grad student finally found the culprit, a smaller version of a gene called SMARCAD1. ( Get a genetics overview. ) The larger SMARCAD1 is expressed throughout the body, but the smaller form acts only on the skin . (See skin pictures .) American Journal of Human Genetics.
