Synthetic Life after GMO's,
" n a cold weekend last month, more than two thousand undergraduate scientists took over two levels of Boston’s Hynes Convention Center. Some wore full-body banana costumes, many wore coördinated team sweatshirts, and all appeared sleep-deprived. A handful of professors, one of whom was dressed as a stuffed olive, wandered among the students, and members of the F.B.I.’s Biological Countermeasures Unit handed out “BACTERIA OF INTEREST” trading cards—the microbial equivalent of the deck that the Pentagon created, in 2003, of Saddam Hussein and his loyalists.
The occasion was the 2014 iGEM Giant Jamboree, a global contest to design and build novel forms of life. (GEM stands for “genetically engineered machine.”) At the core of the Jamboree was a discipline called synthetic biology. Whereas developers of genetically modified organisms—herbicide-resistant soybeans, carotene-enriched rice, faster-growing salmon—tweak a plant or an animal’s DNA with genes borrowed from elsewhere in nature, synthetic biologists assemble new gene sequences from scratch."

Et l'homme créa sa première enzyme de toute pièce,
" Des scientifiques britanniques ont réussi pour la première fois, lundi, à créer une enzyme synthétique prouvant que les être vivants peuvent être constitués par un élément autre que l’ADN, tel que nous le connaissons à ce jour."

New synthetic biology achievment raises questions about possibilities for life on other planets,
" All life on earth, including your own, depends on a series of chemical reactions that require enzymes to catalyze or jump-start the process. Simply put, you couldn’t digest your food or make DNA without enzymes. Now, English researchers have made the world’s first synthetic enzymes, created from artificial molecules (not occurring in nature), yet still capable of triggering chemical reactions. Their research advances the field of synthetic biology while also providing a possible platform on which to base a new generation of drugs. It also may open our eyes to life on other planets."
