The CRISPR Revolution [ungated: 1,2,3] - "Biologists continue to hone their tools for deleting, replacing or otherwise editing DNA and a strategy called CRISPR has quickly become one of the most popular ways to do genome engineering. Utilizing a modified bacterial protein and a RNA that guides it to a specific DNA sequence, the CRISPR system provides unprecedented control over genes in many species, including perhaps humans. This control has allowed many new types of experiments, but also raised questions about what CRISPR can enable." [more inside]
Just as Dante found it easier to conjure the pains of Hell than to evoke the joys of Heaven, so too do bioethicists find it easier to concoct the possible perils of a biotech-nanotech-infotech future than to appreciate how enhancements will contribute to flourishing lives. One of the chief goals of this symposium is to think about the indispensable role that virtue plays in human life. The chief motivating concern seems to be the fear that biotechnologies and other human enhancement technologies will somehow undermine human virtue. As we will see, far from undermining virtue, biotech, nanotech, and infotech enhancements will tend to support virtue; that is, they will help enable people to be actually good.
We may soon be able to clone Neanderthals. But should we? An essay from Archaeology Magazine examines the ethical, scientific and legal ramifications. (Via Heather Pringle's Time Machine blog, where essay author Zach Zorich posted a reply and elicited a response.) [more inside]
U.S. military practices genetic discrimination in denying benefits. "Those medically discharged with genetic diseases are left without disability or retirement benefits. Some are fighting back."
Dolly the Sheep cloned five years ago has arthritis already. Already this year we've had pigs cloned for trasplants. Where is this all going and how ethical is it?
