It took evolution millennia to create these bacteria. Scientists invented new DNA for them in just a few years.
Replying to @nytimes
scary stuff, humans are not able to view anything carefully in long term perspective, there's no such power in our brains, computers also not able to calculate all consequences. Historically everything humans open and discover - like invention of synthetic polymers - the plastics
makes a huge migraine in the future, because the people who made plastics never even thought that they need invent the recycling & destruction method for their invention together. So main question - does this synthetic bacteria have a self-destruct gene or not? it's stupid if not
