A consortium of distinguished scientists is advocating for a profound deliberation on the potential hazards posed by life forms comprised of ‘mirror-image molecules’, citing the substantial risks these entities could present to global well-being.
Although these eerie organisms have not materialized yet, the authors emphasize the critical necessity of introspection before venturing into the realm of mirror images.
“Motivated by curiosity and potential applications, some scientists have initiated efforts to develop life forms exclusively utilizing mirror-image biological molecules,” assert the 38 experts in a Science commentary.
“Such mirror organisms represent a radical departure from conventional life forms, and their creation demands meticulous scrutiny.”
All known life originates from ‘right-handed’ nucleotides in our DNA and RNA, and ‘left-handed’ amino acids that combine to form proteins. This intrinsic characteristic, referred to as homochirality, is a fundamental aspect of our biosphere’s chemical processes with no room for alternative configurations.
Furthermore, mirror-image variations of our amino acids and nucleotides do exist, prompting researchers to contemplate the feasibility of a novel life form based on these inverted molecules.
Although the allure of producing mirror-image molecules is substantial, scientists caution against the creation of mirror bacteria due to the potential replication challenges that could ensue. The incompatibility with ‘natural’ life forms raises concerns about the unchecked proliferation of mirror organisms.
While the prospects of synthetic biology are promising, the hazards associated with building mirror bacteria necessitate a comprehensive and regulated global discourse on the matter. It is crucial to navigate the intersection of scientific advancement and potential risks effectively.
