I'm going to guess you didn't actually bother to read the article then:
Yeah you only have to kill the source of the stem cells. So ridiculous!
No! Induced Pluripotent Stem Cells are simply (usually) skin cells that have been 'regressed' back to the state of stem cells. There is absolutely no requirement to kill the source creature. It would be slightly unfortunate if this were the case, as they are currently being used in medical research to treat various issues such as age related macular degeneration (age related blindness) or the creation of artificial livers.
The article could have been spun to be about anything else under the sun, from efficiency to nutrition, and all we can do is kow-tow to the PETAveg crowd?
Spin is the bane of honest reporting. But, again, going back to the article:
"...cultured meat may need 35% to 60% less energy, occupy 98% less land, and produce 80% to 95% less greenhouse gases than conventional meat."
Well, what do you know, other potential benefits of the technology were addressed within the article. The fact that the summary chose to accentuate the possibility of creating meat without killing animals is not really representative of the entire article. In fact, if anything it's quite the reverse:
"Cultured meat is now grown in medium with fetal calf serum, a supplement made from blood collected at slaughterhouses; scientists have yet to find an alternative that doesn't involve dead animals."
However, I strongly suspect that the issue here is not one of inability but practicality. It would be quite possible to take blood from live animals, not killing them, and extract the serum this way. I'm just not sure why you'd bother, given the rate that biotechnology is advancing. We will soon have the knowledge and skills required to create the necessary culture 'soup' or medium, all within the laboratory.
I do find it slightly amusing that the presentation is due to be held in an arts centre. But is it really art?
