A ‘Kill Switch’ for Rogue Microbes (by Katherine Bourzac, 08/20/2010, TechnologyReview)

“A new type of genetic switch gives bioengineers better control over microbes.

Biologists often speak of switching genes on and off to give microbes new abilities–like producing biofuels or drugs, or gobbling up environmental toxins. For the most part, though, it’s nearly impossible to turn off a gene without deleting it (which means you can’t turn it on again). This limits biologists’ ability to control how much of a particular protein a microbe produces. It also restricts bioengineers’ ability to design new microbes.” [read original article]

Israel’s Value to Transhumanism

Israel’s Value to Transhumanism (h+ magazin)

„Imagine this sci-fi scenario: A small tribe with unique literature, customs and myths believes they’ve been “chosen” for a glorious destiny. But they’re driven out of their native land, forced to wander the globe for aeons, persecuted and annihilated, until they’re impelled by a utopian novel to return to their homeland. They name their new city after the inspirational book and their country becomes a technological powerhouse… but still, they’re surrounded by enemies. They wage eternal war, they hover between hope and apocalypse… their contributions to humanity are astounding but they continue to fear total extinction.“ [read original article]

DNA Not The Same In Every Cell Of Body: Major Genetic Differences Between Blood And Tissue Cells Revealed

ScienceDaily (July 16, 2009) — „Research by a group of Montreal scientists calls into question one of the most basic assumptions of human genetics: that when it comes to DNA, every cell in the body is essentially identical to every other cell. Their results appear in the July issue of the journal Human Mutation. This discovery may undercut the rationale behind numerous large-scale genetic studies conducted over the last 15 years, studies which were supposed to isolate the causes of scores of human diseases.“ [read original article]

Stephen Hawking: “Humans Have Entered a New Stage of Evolution”

„Although It has taken homo sapiens several million years to evolve from the apes, the useful information in our DNA, has probably changed by only a few million bits. So the rate of biological evolution in humans, Stephen Hawking points out in his Life in the Universe lecture, is about a bit a year. „ [read original article]

ENGINEERING BIOLOGY – A Talk with Drew Endy (Edge)

„The only thing that hasn’t been engineered are the living things, ourselves. Again, what’s the consequence of doing that at scale? Biotechnology is 30 years old; it’s a young adult. Most of the work is still to come, but how do we actually do it? Let’s not talk about it, let’s actually go do it, and then let’s deal with the consequences in terms of how this is going to change ourselves, how the biosecurity framework needs to recognize that it’s not going to be nation-state driven work necessarily, how an ownership sharing and innovation framework needs to be developed that moves beyond patent-based intellectual property and recognizes that the information defining the genetic material’s going to be more important than the stuff itself and so you might transition away from patents to copyright and so on and so forth.“ [read original article]

„WE ARE on the brink of technological breakthroughs that could augment our mental powers beyond recognition. It will soon be possible to boost human brainpower with electronic “plug-ins” or even by genetic enhancement. What will this mean for the future of humanity?“ [read original article]

Neuroimplantate, pharmakologisches Menschendesign und Elitenzucht?

Jörg Auf dem Hövel (telepolis, 11.04.2009)

„Die Welt im Jahr 2070 – Teil 1

Die Cyborgs sind schon lange unter uns. Klinisch eingesetzte Implantate und künstliche Organe gehören zum Alltag der Krankenhäuser in den Industrienationen. Angefangen bei Linsen und Zähnen, zieht sich die Reihe über Knochenimplantate, künstliche Hüften, Gelenke, Sehnen und Brusteinsätze bis hin zu Membranen und Herzklappen. Dazu kommen in den letzten Jahren Methoden, die über Elektro-Stimulation und eingebaute Chips mehr oder minder direkt mit dem Gehirn Kontakt aufnehmen. Während die Ärzte forschen und operieren, diskutiert die techno-affine Öffentlichkeit die Phänomene dieser invasiven Technik unter Begriffen wie “Brain Computer Interface” oder Mensch-Maschine-Schnittstellen.“ [zum Originalartikel]

Die Welt im Jahr 2070 – Teil 2

“Der Erfolg der zukünftigen Implantat- und Pharma-Technik wird sich zum einen an dem praktisch Möglichen orientieren, zum anderen aber auch nach den Medien verhandelten Körperbildern richten. Diese Bilder wiederum entstehen in einem Meinungsraum, der den wirtschaftlichen Interessen der Medien, aber auch den realen Lebensverhältnissen Rechnung trägt. Anders formuliert: Je krisenhafter die Lebensbedingungen der Menschen (und das ist sowohl ökonomisch wie mental gemeint) sein werden, umso eher werden sie geneigt sein, den Verheißungen einer Technik zu glauben, die sie “weiter bringt”, nämlich “von hier weg”, und sie damit gleichsam erneuert.” [zum Originalartikel]
