    You really should give direct references. <https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.133.013201>

    Summary:
    They succeeded in exiting a isomeric resonance in the ^{229}Th nucleus
    at about 8 eV, with a lifetime of about 600 second. (so in the far UV,
    using a fluorite crystal that is still transparent at this wavelength)

    This may be used to create a still more accurate frequency standard,
    hence a clock. (eventually)

    Nothing very 'amazing' or 'astonishing' about it,
    just another decade of precision gained,
    after a decade of hard experimental work,

    And in the meantime in the real world - forbidden
    by your bunch of idiots improper clocks keep
    measuring improper t'=t in improper seconds.
