ZF_1_07 — Submarine Geology and Ocean Trenches
The submarine geology of the ocean floor encompasses a vast range of geological features — from abyssal plains (the flattest surfaces on Earth, at 3,000–6,000 m depth, covered by fine sediment) to mid-ocean ridges (the l
Z_5_23 — Gene Drives: CRISPR-Based Inheritance Manipulation and Ecological Engineering
A gene drive is a genetic engineering technology that biases inheritance in sexually reproducing organisms, causing a modified gene to spread through a population at rates far exceeding normal Mendelian inheritance (~50%
Z_5_01 — CRISPR Applications and Genetic Engineering
CRISPR-Cas9 (Clustered Regularly Interspaced Short Palindromic Repeats) is a revolutionary gene-editing technology adapted from a bacterial immune defense system, enabling precise, programmable modification of DNA in vir
Z_3_06 — Genetics of Circadian Rhythms
Circadian rhythms — endogenous ~24-hour oscillations in physiology and behavior — are generated by an intracellular transcription-translation feedback loop (TTFL) encoded by a set of core clock genes conserved across ani
Z_3_02 — Epigenetic Inheritance & Transgenerational Effects
Epigenetic inheritance refers to the transmission of phenotypic information across generations through mechanisms other than changes in DNA sequence. The three primary molecular mechanisms — DNA methylation, histone modi
Z_3_09 — Conservation Genetics and Endangered Species
Conservation genetics applies population genetics, genomics, and molecular biology to the preservation of biological diversity. At its core is the recognition that genetic diversity — the raw material for adaptation to c
Z_2_13 — Pharmacogenomics and Personalized Medicine
Pharmacogenomics — the study of how genetic variation influences drug response — is among the most clinically actionable applications of human genetics. Adverse drug reactions (ADRs) are the 4th–6th leading cause of deat
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_09 — Mitochondrial Genetics and Diseases
Human mitochondrial DNA (mtDNA) is a 16,569-bp circular genome encoding 37 genes: 13 proteins (all subunits of the oxidative phosphorylation/OXPHOS complexes I, III, IV, and V), 22 transfer RNAs, and 2 ribosomal RNAs. Un
Z_2_16 — Cancer Genomics & Precision Oncology
Cancer genomics — the comprehensive analysis of the genetic alterations that drive cancer initiation, progression, and resistance to therapy — has transformed oncology from a tissue-of-origin classification system into a
Z_2_23 — Immune System & Immunology
The immune system is a multi-layered defense network that protects organisms against pathogens including bacteria, viruses, fungi, and parasites. It comprises two interconnected arms: innate immunity, which provides rapi
Z_1_05 — Genomic Imprinting and Parent-of-Origin Effects
Genomic imprinting is an epigenetic phenomenon in which a gene's expression depends on whether it was inherited from the mother or the father — violating the standard Mendelian assumption that both parental copies functi
Z_1_11 — Polyploidy and Genome Duplication
Polyploidy — the possession of more than two complete sets of chromosomes — is a major force in genome evolution, particularly in plants and some animal lineages. Susumu Ohno (1970) proposed that whole genome duplication
Z_4_06 — Psychedelic Neurochemistry: 5-HT2A, Tryptamines, and Molecular Mechanisms
Psychedelic neurochemistry — the molecular-level study of how psychedelic compounds alter brain function to produce their characteristic effects (visual hallucinations, synesthesia, ego dissolution, mystical-type experie
Z_4_23 — Memory as Physical and Molecular Phenomenon
What is a memory made of? The question has driven neuroscience from Santiago Ramón y Cajal's 1894 hypothesis that learning strengthens connections between neurons, through Donald Hebb's 1949 postulate that "neurons that
Z_4_04 — RNA Biology: Types and Functions
RNA (ribonucleic acid) — once considered merely a passive intermediary between DNA and protein — is now recognized as the most functionally diverse class of biological macromolecules, performing roles in catalysis, gene
K_3_02 — Embodied Cognition
Embodied cognition is a broad research program challenging the classical cognitive science view that the mind is essentially a computer processing abstract symbols in the brain. Instead, embodied cognition holds that thi
K_3_19 — Electrical Synapses and Gap Junctions in Consciousness
Most neuroscience focuses on chemical synapses, but the brain also uses electrical synapses formed by connexin-36 gap junctions — direct cytoplasmic channels that pass ions and small molecules between neurons. These prov
K_3_10 — Fetal and Infant Consciousness
The question of when consciousness emerges during human development — whether prenatally, at birth, or gradually through infancy — is one of the most consequential in consciousness studies, with direct implications for f
K_3_01 — Machine Consciousness — Can AI Be Aware?
The question of machine consciousness — whether artificial systems can be genuinely aware rather than merely simulating awareness — stands at the intersection of philosophy of mind, neuroscience, and computer science. Jo
