ZF_5_08 — Coastal Geomorphology: Erosion, Beaches, and Barrier Islands

Coastal geomorphology is the study of landforms at the interface of land and sea — a dynamic zone shaped by the constant interaction of waves, tides, currents, wind, rivers, geology, biology, and increasingly by human ac

Z_2_07 — Genetics of Disease Resistance

Infectious disease has been the most powerful selective force shaping the human genome, leaving signatures across thousands of loci. The best-understood example is sickle cell disease (HbS, Glu6Val in HBB): heterozygous

ZB_5_17 — Constructal Law & Flow Architecture: Why Nature Branches the Way It Does

Most fractal descriptions of nature are descriptive: they observe that rivers branch like blood vessels, blood vessels branch like trees, trees branch like lightning bolts, and lightning bolts branch like river deltas. A
