Over the past few years, many theoretical computations have suggested at least a dozen different crystal structures for this phase of carbon, but new experiments showed that only one crystal structure fits the data: M-carbon.

They predict this absorbption imaging technique should prove useful in quantum information processing and using the minimum amount of illumination for bio-imaging of light-sensitive samples.
