致命镜像：一种与人类相似的新生命形式可能毁灭地球

A new form of life, eerily like us, is almost within reach of science. It could destroy our planet. Here’s how to stop it LET’S SAY IT’S 2036, and scientists are working on a new class of drugs. These medications are mirror-image versions of the molecules your body uses to fight disease. Their big advantage is that reverse compounds last longer in the body because destructive enzymes don’t recognize them and rip them apart. Yet the compounds are still effective against invading microbes. Clinical trials have been promising, and the team is eager to scale up production. The researchers turn to engineered mirror bacteria—single cells made of reversed molecules—for the job. Bacterial factories aren’t a far-fetched idea. …
