T_2_14 — Hypnosis: Suggestion, Trance, and the Science of Hypnotic Phenomena
Hypnosis — a procedure involving an induction (typically relaxation and focused attention instructions) followed by suggestions for changes in perception, sensation, emotion, thought, or behavior — has oscillated between
Y_4_12 — Psychosomatic Phenomena and the Placebo Effect
Psychosomatic phenomena — bodily changes produced by mental states — and the placebo effect — measurable physiological improvements following inert treatment — demonstrate that consciousness and belief can directly affec
Y_5_05 — Psychic Phenomena: Meta-Analyses and Scientific Evaluation
Parapsychology — the scientific study of purported psychic (psi) phenomena including telepathy, clairvoyance, precognition, and psychokinesis — occupies a unique and contested position in science. Over 130+ years, thousa
ZA_5_03 — Infrasound — Physics, Biological Effects, and Anomalous Phenomena
Infrasound — sound below the conventional human hearing threshold of ~20 Hz — is a pervasive physical phenomenon generated by natural sources (wind, ocean waves, volcanic eruptions, earthquakes, thunderstorms, animal voc
ZH_5_07 — Light and Shadow Hierophanies: Temple Sun Daggers and Solar Inserts
A hierophany — a manifestation of the sacred — is realized in some of the world's most famous ancient structures through the precise interplay of light and shadow. On specific calendar dates — typically solstices, equino
K_5_18 — Working Memory: Cognitive Architecture and Executive Function
Working memory (WM) is the cognitive system responsible for temporarily holding and manipulating information during complex tasks such as reasoning, language comprehension, and decision-making. Distinguished from passive
K_5_20 — Psychoneuroimmunology: Mind-Body-Immune Connections
Psychoneuroimmunology (PNI) — the study of interactions between psychological processes, the nervous system, and immune function — has established that the mind directly influences immune defense and that immune activity
Q_3_01 — The Fermi Paradox & Drake Equation
Enrico Fermi's 1950 lunch question — "Where is everybody?" — remains one of the deepest unanswered questions in science. The galaxy is ~13.6 billion years old, contains ~100–400 billion stars, and (as we now know from Ke
Q_3_07 — Plasma Cosmology and the Electric Universe Hypothesis
Plasma cosmology and its populist extension, the Electric Universe (EU) hypothesis, propose that electromagnetic forces — rather than gravity — are the dominant organizing force in the cosmos, and that plasma (ionized ga
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
O_1_12 — The Hum: Worldwide Low-Frequency Acoustic Anomaly
"The Hum" refers to a persistent, low-pitched, droning noise perceived by a small but significant percentage of the population (estimated 2–11% depending on the locality and study) in diverse locations worldwide. The Hum
O_1_08 — Aurora Borealis and Geomagnetic Storms
The aurora borealis (northern lights) and aurora australis (southern lights) are luminous atmospheric phenomena caused by charged particles from the solar wind interacting with Earth's magnetosphere and exciting atmosphe
O_1_19 — Naga Fireballs
The Naga fireballs (bung fai phaya nak, บั้งไฟพญานาค, literally "Naga sky rockets") are glowing orbs reported to rise from the Mekong River in the Nong Khai Province of northeastern Thailand (and the opposite Laotian ban
O_1_11 — Earthquake Lights — Comprehensive Evidence and Mechanisms
Earthquake lights (EQLs) are anomalous luminous phenomena — flashes, glows, flames, orbs, and columns of light — reported in association with earthquakes throughout recorded history. Once dismissed as anecdotal or imagin
O_4_03 — Skinwalker Ranch & Multi-Phenomenon Sites
Skinwalker Ranch is a 512-acre property in the Uintah Basin of northeastern Utah that has been the subject of reported anomalous phenomena including unidentified aerial objects, unusual animal behavior and mutilation, po
O_4_09 — Singing Sands, Booming Dunes, and Anomalous Desert Acoustics
Singing sands and booming dunes are natural acoustic phenomena in which sand produces audible sound — sometimes at extraordinary volume (up to 105 dB, comparable to a chainsaw at 1 m) — when disturbed by wind, avalanchin
O_4_16 — Singing Sands and Booming Dunes: Acoustic Geomorphology
Certain sand dunes and beaches worldwide produce sustained, audible tones — a phenomenon documented since antiquity and reported by travelers from Marco Polo (1295 CE, describing "singing sands" in the Taklamakan Desert)
O_3_19 — Ice Circles
Ice circles (also called ice discs or ice pans) are circular slabs of ice that form in slow-moving rivers, streams, and occasionally lakes, and rotate slowly on the water surface. They range from a few centimeters to ove
O_3_18 — Rogue Waves: Extreme Ocean Dynamics and Nonlinear Wave Physics
Rogue waves (also called freak waves, killer waves, or extreme waves) are individual ocean waves whose height exceeds twice the significant wave height ($H > 2H_s$) of their surrounding sea state, appearing without warni
T_5_05 — Parapsychology and Anomalous Cognition
Parapsychology is the scientific study of claimed anomalous psychological phenomena — particularly extrasensory perception (ESP) (telepathy, clairvoyance, precognition) and psychokinesis (PK) (mental influence on physica
