Sweet Jesus! Scientists have discovered gravity! In addition, to add insult to injury, as things get closer they only increase the gravity between them. Soon, the world will collapse into a swirling singularity if we don't take swift, immediate action. Refrain from forming crowds. Be cautious not to marry your dinner service. Only you can prevent black holes.

The reasoning of this article is incredibly specious. There is no adequate evidence or inference that mirror cells would have any advantages over standard life forms. Isomers aren't incredibly divergent structures that nature fails to handle on a massive scale. Isometric molecules are a basic part of molecular life. Mirror cells would have the same biotic survivorship of the rest of the cells on the planet.
By synthesizing cells that use a proportion of molecules that have an inverse chirality to the majority of biotic life we're not exactly making cancer airborne and contagious.
They wouldn't have an inherently higher survivorship, but it would be toxic to predators, wiping them out (either directly by toxicity, or indirectly by starvation), at the same time as growing and spreading further. Natural evolution itself is unlikely to develop an organism capable of metabolizing mirror sugars, fats, proteins.
So this means people have to take an active role in eradicating this life form, if it ever comes to be.
