W_5_24 — Civilization Collapse & Systems Fragility
Civilizational collapse — the rapid, significant decline of a complex society's political, economic, and social institutions — is a recurring pattern in human history. Major examples include the Western Roman Empire (476
ZH_5_02 — Megalithic Lunar Observatories: Thom's Hypothesis Revisited
The hypothesis that Neolithic and Bronze Age megalithic monuments in Britain, Ireland, and Brittany functioned as sophisticated lunar observatories — capable of tracking the Moon's complex motions to high precision — is

This document examines Women and Gender in Ancient Knowledge Traditions, a topic within the Global Traditions research area. Key areas of investigation include The Gender Gap in This Project, Scale of the Issue, Upper Pa
C_5_21 — Serpent-DNA Visual Parallels: The Double Helix in Ancient Iconography
Entwined serpent imagery — two serpents coiling around a central axis — appears across civilizations separated by vast distances and millennia: the caduceus of Greek Hermes (two serpents around a winged staff), the Nehus

Venus, the brightest object in the sky after the Sun and Moon, plays a central role in myths across every major civilization. The Sumerians identified Inanna as the planet Venus, whose descent to and return from the unde
ZF_2_07 — Marine Microbiology and Plankton
Marine microorganisms — bacteria, archaea, protists, viruses, and microscopic algae — constitute the invisible foundation of ocean life, driving global biogeochemical cycles, producing roughly half of the world's oxygen,
ZF_5_10 — Marine Biotechnology: Blue Pharmacy and Ocean Genetic Resources
The ocean harbors an estimated 2.2 million species (most undescribed) across environments spanning freezing polar waters to superheated hydrothermal vents, anoxic sediments to UV-drenched coral reefs — a staggering diver
ZF_5_21 — Invasive Species: Ecological Disruption, Biosecurity, and Marine Invasions
Invasive species — organisms introduced outside their native range that cause ecological, economic, or health damage — represent one of the top five drivers of global biodiversity loss, alongside habitat destruction, ove
ZF_5_04 — Aquaculture: Fish Farming, Mariculture, and Blue Revolution
Aquaculture — the farming of aquatic organisms including fish, shellfish, crustaceans, and seaweed — has become the fastest-growing food production sector in the world and now provides more seafood for human consumption

The human brain is approximately three times larger than expected for a primate of our body size, with a vastly expanded cerebral cortex containing ~86 billion neurons. Identifying the genetic basis for this extraordinar
Z_2_08 — Prion Genetics and Misfolded Proteins
Prions are infectious agents composed entirely of misfolded protein — the only known pathogen that contains no nucleic acid (no DNA, no RNA). The protein-only hypothesis (Stanley Prusiner, 1982 — Nobel Prize 1997) states
