Gold`s wobbly nucleus: What the short-lived Au187 isotope teaches us about fundamental science research
(PHYSorg.com Physics)

As Earth rotates along its axis, it wobbles a little bit. This wobbling comes, in part, from how mass is distributed across the planet. Nuclear physics researchers have now observed this same type of wobbling in Au187-a gold isotope that lives for just eight minutes. Fundamental science research like this can lead to major breakthroughs in a range of fields, including medical care.
