Scientists have proposed what they believe is the first way to detect "mirror life," a hypothetical form of life built from molecules that are reversed versions of those found in living organisms on Earth.

Researchers from the University of Strathclyde and Durham University have developed a proposed detection technique that uses molecules capable of emitting light with distinct left and right-handed properties. By analyzing these light signals, scientists may eventually be able to distinguish conventional organisms from their mirror-image counterparts.

Although mirror life does not currently exist, some experts consider its potential creation a serious biological safety concern.…
