Anoikis
Anoikis (Greek "homelessness") is apoptosis triggered by loss of cell-ECM attachment, first named by Frisch and Francis in 1994; anoikis resistance lets cancer cells survive detachment and metastasize.
Anointing
Anointing is the ritual application of oil, fat, or perfumed chrism to a person or object as a religious act, marking elevation, consecration, or healing.

The anointing of Jesus is a Gospel episode in which a woman pours expensive nard oil over Jesus, an act he interprets as preparation for his burial.

Anolidae
Anolidae, formerly Dactyloidae, is the lizard family containing anoles (genus Anolis and relatives), about 454 species from the Americas and West Indies, defined by adhesive toe pads and a dewlap; Anolidae Cocteau 1836 has nomenclatural priority.
Anolis
Anolis, the anoles, a large neotropical lizard genus (about 300–426 species) famed for Caribbean adaptive radiation, convergent ecomorphs, dewlap signaling, the green anole genome, and invasive brown anoles.
Anomabo
Anomabu, also spelled Anomabo and historically Annamaboe, is a Fante town in Ghana's Central Region that grew into a major Atlantic slave-trading port, with the British Fort William still standing on its shore.
Anomalies of dental arch relationship
Anomalies of dental arch relationship, ICD-11 code DA0E.2 (ICD-10 K07.29), are congenital or acquired deviations of how the upper and lower dental arches relate, including overjet, deep overbite, disto-occlusion, mesio-occlusion, and midline deviation.
Anomalies of pupillary function
Anomalies of pupillary function (ICD-11 LA11.62; pupillary disorder, anomaly of pupil function) is a group of conditions in which iris muscles fail to regulate light entering the eye, covering miosis, mydriasis, hippus, iridoplegia, and myotonic pupil.
Anomalies of tooth position
Anomalies of tooth position (ICD-11 DA0E.3, formerly ICD-10 M26.3): crowding, diastema, displacement, rotation, transposition, and impaction of teeth; classified as ectopic, transmigration, transposition, rotation; treated orthodontically.
Anomalisa
Anomalisa is Charlie Kaufman and Duke Johnson's 2015 R-rated stop-motion animated drama, adapted from a 2005 sound play, about customer-service guru Michael Stone, voiced by David Thewlis, whose Fregoli hotel stay in Cincinnati features Tom Noonan voicing everyone but Lisa (Jennifer Jason Leigh).
Anomalo
Anomalo (formerly Data Gravity) is an AI-powered enterprise data quality monitoring platform founded in 2018 in Palo Alto by Instacart alumni Elliot Shmukler and Jeremy Stanley, using unsupervised machine learning to detect anomalies.
Anomalocaris
Anomalocaris ("abnormal shrimp") is an extinct Cambrian radiodont genus of stem-group arthropods; type species A. canadensis Whiteaves 1892 from the Burgess Shale, a nektonic predator with raptorial frontal appendages and a suction-type oral cone, not a Peytoia.
Anomalous aortic origin of a coronary artery
Anomalous aortic origin of a coronary artery (AAOCA, ACAOS) is a congenital defect where a coronary artery arises from the wrong aortic sinus; found in up to 1% of people, a leading cause of sudden cardiac death in young athletes, managed by risk stratification and unroofing surgery.
Anomalous aortic origin of the left coronary artery
AAOLCA, anomalous aortic origin of the left coronary artery from the right aortic sinus, a rare congenital coronary anomaly; rarer than the right-coronary form but carrying higher risk of ischemia and sudden cardiac death in young athletes, treated by unroofing surgery.
Anomalous aortic origin of the right coronary artery
Anomalous aortic origin of the right coronary artery (AORCA, R-ACAOS): congenital origin of the right coronary artery from the left aortic sinus, often interarterial or intramural; usually asymptomatic but a cause of exertional sudden cardiac death in young athletes.
Anomalous diffraction
Anomalous diffraction is the resonant contribution to x-ray diffraction when the x-ray energy approaches an atom's absorption edge, exploited by MAD and SAD methods to solve the crystallographic phase problem.
Anomalous dimension
The anomalous dimension, written η, is a critical exponent measuring how correlations decay at a continuous phase transition, differing from mean-field theory; the 3D Ising value is about 0.0363.
Anomalous dispersion
Anomalous dispersion is the behavior of a material's refractive index near an absorption resonance, where it decreases with increasing frequency instead of increasing; the effect was named by August Kundt in 1871.
Anomalous Floquet–Anderson insulator
The anomalous Floquet–Anderson insulator (AFAI) is a topological phase of periodically driven two-dimensional quantum systems in which disorder localizes all bulk states while chiral edge modes still propagate.
Anomalous Hall effect
The anomalous Hall effect is a voltage transverse to an electric current in magnetic materials without an applied magnetic field, arising from magnetization and spin-orbit coupling.
Anomalous left coronary artery from the pulmonary artery
ALCAPA, or Bland-White-Garland syndrome, is a rare congenital defect where the left coronary artery arises from the pulmonary artery, causing coronary steal, infant heart failure, and over 90% first-year mortality without surgery.
Anomalous magnetic dipole moment
The anomalous magnetic dipole moment, or magnetic anomaly, is the amount by which a lepton's g-factor exceeds the Dirac value of 2, first calculated by Julian Schwinger in 1948.
Anomalous magnetic moment of the electron
The anomalous magnetic moment of the electron, a_e, is how far the electron's g factor exceeds the Dirac value of 2. It is among the most precisely measured quantities in physics, testing quantum electrodynamics.
Anomalous Nernst effect
The anomalous Nernst effect is a thermoelectric phenomenon in magnetic materials in which a temperature gradient generates a voltage perpendicular to heat flow and magnetization, without an external magnetic field.
Anomalous Nernst effect in topological materials
The anomalous Nernst effect in topological materials is the generation of a transverse voltage by a temperature gradient, requiring no external magnetic field because it arises from Berry curvature.
Anomalous origin of coronary artery from the pulmonary artery
Anomalous origin of coronary artery from the pulmonary artery (ACAPA; ALCAPA, Bland-White-Garland syndrome, or ARCAPA): a rare congenital defect causing coronary steal, infant heart failure, about 90% first-year mortality untreated, and surgical reimplantation as the preferred repair.
