In this week?s Nature Physics an international team, led by Oxford University scientists, report that a short pulse from the FLASH laser ?knocked out? a core electron from every aluminium atom in a sample without disrupting the metal?s crystalline structure. This turned the aluminium nearly invisible to extreme ultraviolet radiation.

but it wasn't around for very long:

"Whilst the invisible effect lasted for only an extremely brief period - an estimated 40 femtoseconds - it demonstrates that such an exotic state of matter can be created using very high power X-ray sources."

Another Pirsig fan....His book had more applicability to metal working, electronic trouble shooting, marriage encounter, and just about every endeavor of peoplekind.
