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
Z_2_20 — Prion Molecular Biology
At the molecular level, prion diseases arise from the conversion of the normal cellular prion protein (PrPᶜ) into a misfolded, aggregation-prone conformer (PrPˢᶜ) through a process that remains one of the most extraordin
E_5_06 — Holocene Sixth Mass Extinction: Current Biodiversity Crisis
The Holocene "Sixth Mass Extinction" hypothesis holds that current species loss rates are 100–1,000 times the normal background extinction rate, driven primarily by human activity: habitat destruction, overexploitation,
Q_2_12 — Cosmic Nucleosynthesis and Primordial Helium Abundance
Big Bang nucleosynthesis (BBN) — the formation of the lightest elements during the first ~20 minutes after the Big Bang — stands as one of the most remarkable quantitative successes of modern cosmology. With only one fre
ZB_5_14 — Conservation Biology
Conservation biology — the scientific study of biodiversity loss and the methods to protect species, habitats, and ecosystems — was formally established as a discipline by Michael Soulé (University of California, San Die
ZB_5_15 — Citizen Science in Ecology: Participatory Research and Large-Scale Biodiversity Monitoring
Citizen science — the participation of non-professional volunteers in scientific research — has become an indispensable component of modern ecology, generating datasets of unprecedented spatial and temporal scale that no
ZB_5_05 — Extinction Biology and De-Extinction
Extinction — the complete disappearance of a species — is a permanent event that has shaped life's history as profoundly as origination. Background extinction (the normal, continuous loss of species) proceeds at ~0.1–1 s
ZB_4_11 — Island Ecology: Biogeography, Endemism, and Evolutionary Radiation
Island ecology — centered on the theory of island biogeography developed by Robert MacArthur and Edward O. Wilson (1963, 1967) — provides one of ecology's most influential theoretical frameworks, explaining how species d
ZB_4_08 — Rewilding and Ecological Restoration
Rewilding is an emerging approach to conservation that aims to restore self-sustaining, self-regulating ecosystems by reintroducing missing species — particularly large vertebrates and ecological engineers — and allowing
ZB_3_04 — Ecological Succession
Ecological succession — the process of community change over time following a disturbance or the creation of new habitat — is one of ecology's oldest and most studied concepts. Primary succession occurs on newly exposed
G_1_05 — eDNA and Environmental DNA — Reading Invisible Life
Environmental DNA (eDNA) refers to genetic material shed by organisms into their environment — through skin cells, mucus, feces, urine, gametes, decomposing tissue, pollen, root exudates, and other biological residues —
G_1_06 — Paleoproteomics — Ancient Proteins Beyond DNA
Paleoproteomics is the extraction, identification, and analysis of ancient proteins from archaeological and paleontological materials — an emerging molecular method that extends biological identification far beyond the t
O_3_01 — Biodiversity, Ecosystem Intelligence, and the Superorganism
Earth harbors an estimated 8.7 million eukaryotic species (Mora et al. 2011), of which only ~1.5-1.8 million have been formally described — meaning roughly 80% of species remain unknown to science. When prokaryotes (bact
B_5_08 — New Animism: Relational Ontology and Perspectivism
"New animism" refers to a scholarly reinterpretation of animism — the attribution of life, intentionality, personhood, or agency to non-human entities (animals, plants, stones, rivers, weather phenomena, artifacts) — tha
B_2_11 — Wild Man, Sasquatch, and Hairy Hominid Traditions
The figure of the "wild man" — a large, hairy, human-like being dwelling in wilderness — constitutes one of the most persistent and geographically widespread archetypes in human tradition. From Enkidu in the Epic of Gilg
L_4_12 — CRISPR Gene Drives and Population Genetics Ethics
CRISPR gene drives — genetic engineering systems that combine CRISPR-Cas9 gene editing with super-Mendelian inheritance to spread a modified gene through an entire wild population far faster than natural selection — repr
P_2_08 — Transhumanism and Enhancement Ethics
Transhumanism is the philosophical and cultural movement advocating the use of technology to fundamentally enhance human capacities — cognitive, physical, emotional, and moral — beyond the limits set by biological evolut
ZE_3_03 — Animal Ethics and Rights
Animal ethics addresses the moral status of non-human animals and the ethical obligations humans have toward them — a field that has been transformed since the 1970s by philosophical arguments challenging the human-cente
ZE_3_01 — Environmental Ethics and Deep Ecology
Environmental ethics examines the moral relationship between humans and the natural environment — Do non-human entities have intrinsic value? Do we have moral obligations to ecosystems, species, and future generations? T
R_3_08 — Speciation Mechanisms and Reproductive Isolation
Speciation — the process by which one species splits into two or more reproductively isolated lineages — is the engine of biodiversity. Ernst Mayr's biological species concept (1942) defines species as groups of interbre
