Friedman’s “The World is Flat” or Neal Stephenson’s “Cryptonomicon”, and you get a glimpse into how the hacker culture that emerged at the tail end of the twentieth century revolutionized the digital world. Will a confluence of emerging technologies—including information tech, biotech, and nanotech—lead to a similar revolution in the biological world? Behind every computer screen is a complexity of software and hardware that together create a virtual world in which many of us spend more time living out our lives than is probably healthy—whether crunching numbers, playing games or churning out our latest blog. DNA trick throws ageing into reverse - health - 29 November 2010. A technique to keep the tips of your chromosomes healthy could reverse tissue ageing.
The work, which was done in mice, is yet more evidence of a causal link between chromosome length and age-related disease. Telomeres, the caps of DNA which protect the ends of chromosomes, shorten every time cells divide. But cells stop dividing and die when telomeres drop below a certain length – a normal part of ageing. The enzyme telomerase slows this degradation by adding new DNA to the ends of telomeres.
Mariela Jaskelioff and her colleagues at the Dana Farber Cancer Institute in Boston, Massachusetts, engineered mice with short telomeres and inactive telomerase to see what would happen when they turned the enzyme back on. Four weeks after the team switched on the enzyme, they found that tissue had regenerated in several organs, new brain cells were developing and the mice were living longer.

A Drug That Could Give You Perfect Visual Memory. Stem-Cell-Coated Contact Lenses Are Curing the Blind. Researchers in Australia have come up with an outwardly simple but incredibly ingenious way of curing blindness caused by corneal damage: Take everyday contact lenses, already used by millions (including me), and infuse them with a patient's own stem cells.
After wearing them for about 2 weeks, test subjects reported a seemingly miraculous restoration of sight. Is it that easy? Most of the patients had only lost vision in one eye, so stem cells were harvested from their good eye and then plated onto contact lenses. After letting the stem cells repair damaged tissues, 2 of the 3 patients went from legally blind to being able to read some of an eye chart. The third patient actually regained enough sight to pass a driving exam. Researchers Create the World's First Fully Synthetic, Self-Repli. If figuring out how to quickly sequence genomes was but the first small step for genetics, Craig Venter has gone ahead and made a giant leap for the discipline.
The J. Craig Venter Institute announced today that it has created the world's first synthetic cell, boasting a completely synthetic chromosome produced by a machine. "This is the first self-replicating species we've had on the planet whose parent is a computer," Venter said in a press conference. The biological breakthrough could have myriad applications, as it essentially opens the door to engineered biology that is completely manipulated by laboratory scientists.
The researchers are already planning to create a specially engineered algae designed to trap carbon dioxide and convert it to biofuel. Though a bacteria cell was the final product in this particular experiment, eukaryotic yeast was a critical player in the process. Human brain: fuse with computer chips biodigital brain.
Computer records animal vision in Laboratory - UC Berkeley. The First Brain Transplant. A TransHuman Dream [with word abuse] Accelerating Future » Top 10 Transhumanist Technologies. Transhumanists advocate the improvement of human capacities through advanced technology.
Not just technology as in gadgets you get from Best Buy, but technology in the grander sense of strategies for eliminating disease, providing cheap but high-quality products to the world’s poorest, improving quality of life and social interconnectedness, and so on. Technology we don’t notice because it’s blended in with the fabric of the world, but would immediately take note of its absence if it became unavailable. (Ever tried to travel to another country on foot?)
Technology needn’t be expensive – indeed, if a technology is truly effective it will pay for itself many times over. Transhumanists tend to take a longer-than-average view of technological progress, looking not just five or ten years into the future but twenty years, thirty years, and beyond. 10. 9.
