TH_05 — The Water-Carbon-Chirality Triple Lock
Life appears to need three separate lucky breaks: water, with all its strange life-friendly quirks; carbon, the one atom flexible enough to build living molecules; and a curious one-handedness, where life uses only "left
O_5_13 — Paleosols and Ancient Soils: Climate Records in Earth
Paleosols — ancient soils preserved in the geological record — are among the most valuable but often overlooked records of past environmental conditions. When soils are buried by subsequent sedimentation (flooding, volca
