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."
