Science roundup: Blue zones, ancient soft tissue, black hole physics

Three fields of science — the study of long human lives, the recovery of ancient biological memory, and the mathematics of cosmic violence — each advanced this week in ways that quietly expand what we believe is knowable. From the blue zones of exceptional longevity to soft tissue preserved across hundreds of millions of years to the gravitational echoes of colliding black holes, researchers are finding that the boundaries of understanding are more permeable than once assumed. What unites these discoveries is not their subject matter but their shared insistence: that the hidden can be found, a
