In the recent frenzy of news reports about "Things That Begin With The Letter 'Terrorist'", "Why We'll Be Reporting About the iPhone For Two More Months", and "Please, God, Stop With the Paris Hilton Already", the story placers just couldn't find any room to put this:
J. Craig Venter Institute Publishes First Bacterial Genome Transplantation Changing One Species to Another
Yes - you read it right. Read it again.
Changing One Species to Another
Admittedly small, Mycoplasma capricolum is nonetheless a known - if somewhat despised - bacteria, known for producing arthritic symptoms in sheep and other livestock.
By a process that the JCVI hasn't entirely explained, they were able to transfer into this Mycoplasma capricolum, the DNA of another bacteria: Mycoplasma mycoides Large Colony (LC). Within several rounds of cell division, the capricolum's original DNA blueprint had disappeared, and the newly-divided cells contained the phenotypical characteristics of mycoides LC.
A series of tests, including an antibody test, indicated that the transfer had taken place, and held. Mycoplasma capricolum had turned into Mycoplasma mycoides LC.
One species, to another. The JCVI team indicated several reasons for working with the Mycoplasma strains: small genomes, lack of a cell wall, among other reasons.
Interestingly enough, though, Mycoplasma mycoides is the etiological agent of contagious bovine pleuropneumonia (CBPP), a highly destructive disease in cattle.
From painful joints in goats, to a destructive pneumonia in cattle. Still, it's not as if the path of progress has ever not been just a bit crooked around.
I believe there is no philosophical high-road in science, with epistemological signposts. No, we are in a jungle and find our way by trial and error, building our road behind us as we proceed.
Max Born (1882-1970) German Physicist. Nobel Prize, 1954.
A teacher of mine once listed the three most important fields of study and progress that will grow beyond the "computer age" (Given the kind of people you run across on MySpace, the "computer age" is well behind us now):
- Biotech
- Materials Science
- Space Travel/Tech
Venter's latest development indicates that the pace of progress is moving swiftly on within the biotech sector. The relative quietness of the media about the discovery indicates to me that we are not yet in "the biotech age".
But consider that we could be. Consider that as early as 2004 the Biotechnology Industry Organization proposed using genetically engineered organisms (GEOs) to clean up pollution.
Consider that 70-75% of all processed foods - stuff you'd pick up at the supermarket - contains at least some genetically modified ingredients.
Consider that companies such as Midland have been providing synthetic DNA for over twenty years.
And consider that today, someone has just succeeded in implanting an entire genome into another organism. And, implanted, that organism changed. Combined with synthetic DNA, we may well be on our way to the beginnings of true genetically engineered organisms, that may hold vital answers to questions of increasing pollution, waning energy reserves, food shortages, and more.
But I guess the major news outlets don't think you'll be excited. They don't think you'll be interested in that.
You'll be more interested in Paula Abdul's reality show.
