INTERDOC_44 — Mass Destruction Events: A Chronological Timeline from Earth's Origin to Present

Earth has experienced at least 20 major destruction events across 4.5 billion years, ranging from planetary-scale mass extinctions that eliminated 75–96% of all species to civilization-ending catastrophes that reset huma

ZB_2_06 — Immune System Evolution: From Innate to Adaptive Defense

The immune system represents one of evolution's most complex adaptive innovations — a multi-layered defense system that distinguishes self from non-self and remembers past encounters. All multicellular organisms possess

ZB_2_05 — Aging, Longevity, and the Biology of Death

Why do organisms age and die? This question — one of the oldest in human inquiry — has yielded remarkable molecular answers in recent decades. Leonard Hayflick's 1961 discovery that human cells have a finite replicative

O_2_02 — Earthquake Prediction — Ancient Seismological Knowledge and Modern Limits

Earthquake prediction remains one of the great unsolved problems of geoscience — despite enormous technological investment, no reliable short-term prediction method exists. Yet ancient civilizations demonstrated remarkab

O_2_03 — Plate Tectonics, Continental Drift, and Deep Earth

Plate tectonics — the theory that Earth's outer shell (lithosphere) is divided into rigid plates that move, collide, and separate atop a convecting asthenosphere — is one of the great unifying theories of modern science.
