More biotech: Cloning from cell samples?

Cellular biologists working for the company Stemagan, based out of San Diego, California, have claimed something amazing: That they've managed to produce human embryos using skin cells from men instead of gametes (NY Times link - use Bugmenot if you need access). The embryos thus produced didn't develop very far, only to the blastocyst stage, but that in itself is a breakthrough. It wasn't necessary to force the division of the third stage for example (which is thought to have happened by accident under laboratory conditions at least once in medical history), for example. However, because embryonic stem cells weren't part …

Another step closer to artificial life - an artificial chromosome.

Geneticist Craig Venter of San Diego, California has made a significant breakthrough in genetics and bioengineering after it's been verified by the scientific community (I have to throw that disclaimer for reasons that'll be made clear in a moment)... he's built a chromosome out of raw materials in vitro.

Yeah. Not only did Venter's team, lead by Nobel Prize winner Dr. Hamilton O. Smith hooked synthetic nucleotides together one by one into a strand of DNA 580,000 base pairs in length, coding for 381 distinct genes, and then got the DNA to coil up into a chromosome. The synthetic …
