Regina Barber: 作为一名右撇子,我深知世界并非总是为所有人设计。最近我了解到,分子的“手性”问题,即分子与其镜像的差异,对生命构成的基本层面都有影响。所有地球上的生命都选择了同一种“手性”,这引发了我对镜像生命可能性的思考。 Carl Zimmer: 我主要研究生命的本质和未来发展。分子的手性,就像镜子中的影像,是分子的镜像。目前,科学家们正在努力创造镜像分子,这引发了关于镜像生命潜在风险的讨论。如果镜像细胞逃逸,由于我们的免疫系统无法识别它们,可能导致无法控制的疫情,对人类、动植物甚至整个生态系统造成灾难性的影响。虽然制造镜像细胞面临许多技术障碍,但科学家们正在朝着这个目标前进。重要的是,科学家们正在公开讨论这项研究的伦理问题,并考虑是否应该完全停止它。我个人认为,我们应该认真思考制造镜像细胞的风险和益处,然后做出明智的决定。

For people with two hands, one is usually dominant. On a molecular level, life takes this to the extreme. All of the DNA in earthly living things twists to the right, whereas the protein building blocks favor a kind of left-handed chemistry. But in recent years, scientists have worked toward a kind of mirror version of life. The technology to make mirror life likely won't exist for at least a decade. Still, a group of concerned scientists published a 299-page technical report calling for a stop to the science. New York Times science columnist Carl Zimmer) explains how a mirror microbe could wreak havoc on life on Earth in the future. **Check out the full technical report) and Carl's full article).**Curious about other controversial research?
