[snip more blahblahblah]
You really should give direct references.
<https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.133.013201>
or the press release with it
<https://newsroom.ucla.edu/releases/nuclear-spectroscopy-breakthrough-could-rewrite-fundamental-constants-of-nature>

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,
