Development economics
Development economics is the branch of economics that studies the economic transformation of low- and middle-income countries, examining why poverty, inequality, and structural change persist despite growth.
Development hell
Development hell: a film, video game, or software project stalled for years in production; canonical cases Duke Nukem Forever (14 years), Kien (22 years), The Last Guardian; causes include scope creep, funding gaps, and reboots.
Development of Grand Theft Auto V
Development of Grand Theft Auto V: Rockstar North's 2008–2013 production of GTA V, with 1,000+ staff, a 1,000-page script, three protagonists, Los Santos field research, and record $1 billion three-day sales.
Development of Minecraft: Java Edition
Development of Minecraft: Java Edition, the original Java-codebase version by Markus 'Notch' Persson (2009), Mojang, and Microsoft; covers snapshots, versioning, modding APIs, and the Vulkan renderer shift.
Development of Star Trek 4
Star Trek 4: the long-developed, ultimately cancelled fourth film of the Kelvin-timeline reboot announced in July 2016, directed at one point by Matt Shakman, distinct from the 1986 film Star Trek IV: The Voyage Home.
Development of the digestive system
Development of the digestive system: embryology of the primitive gut tube from definitive endoderm, foregut/midgut/hindgut derivatives, HOX and SHH patterning, midgut rotation, recanalization, and organoid models.
Development of the embryonic venous system
The embryonic venous system consists of three paired networks, vitelline, umbilical, and cardinal, that are remodeled from about 4 weeks into the adult vena cavae, portal vein, and right atrium.
Development of the face
Development of the face: embryology of facial formation from five prominences (frontonasal, maxillary, mandibular) in weeks 4 to 8, driven by neural crest cells, WNT/BMP/FGF/SHH signaling, and studied via mouse, chick, zebrafish, and frog models.
Development of the human spinal cord
The human spinal cord develops from the neural tube in the fourth week of embryonic life, then ascends within the vertebral canal to end near L1 in adults.
Development of the nervous system in humans
Development of the human nervous system (neurulation): neural tube and neural crest form from ectoderm 2–3 weeks after conception; tube becomes CNS, crest builds PNS; synapses peak at ~150% adult levels in infancy.
Development of the New Testament canon
The development of the New Testament canon is the process by which Christian churches settled on 27 books as Scripture, from the 2nd to 4th centuries.
Development of the reproductive system
Development of the reproductive system: embryology of gonads, genital ducts, external genitalia, and gonadal descent from intermediate mesoderm. Indifferent stage until week 7; SRY, testosterone, and AMH drive male differentiation; female pathway is hormone-independent.
Development of the thymus
Development of the thymus describes how the thymus arises from the third pharyngeal pouch, descends to the chest, is colonized by T cell precursors, and undergoes fat replacement after puberty.
Development of the urinary system
Development of the urinary system: embryonic formation of kidneys, ureters, bladder, and urethra via pronephros, mesonephros, and metanephros stages, ureteric bud branching morphogenesis, nephron induction, and CAKUT malformations.
Development planning
Development planning is the practice by which governments of developing economies prepare formal medium-term plans that coordinate public investment, set growth targets, and guide resource allocation.
Development Plus
Development Plus (Rozwój Plus) is a Polish centre-right movement founded by Mateusz Morawiecki in April 2026, which split from PiS in July 2026, holds about 40 Sejm seats, and polls around 5%.
Development studies
Development studies, also called international development studies, is an interdisciplinary academic field examining how social, economic, political, and ecological factors interact in societal change across local and global levels.
Development theory
Development theory is the body of theory in economics and political science concerned with economic development, from structuralism and dependency theory to the Washington Consensus.
Development-induced displacement
Development-induced displacement is the forced movement of people from their homes, land, or livelihoods caused by development projects such as dams, mines, roads, and urban infrastructure.
Developmental and epileptic encephalopathy with spike-wave activation in sleep
DEE-SWAS, also called EE-SWAS and formerly ESES or CSWS, is a rare childhood epilepsy syndrome with regression of cognition, language, behavior, or motor skills tied to marked sleep-activated 1.5–2 Hz spike-and-wave EEG activity, onset at 2–12 years.
Developmental and reproductive toxicity testing
Developmental and reproductive toxicity (DART) testing exposes rats, rabbits, or other models to chemicals or drugs around pregnancy to measure effects on fertility and offspring development.
Developmental biology
Developmental biology, also called biological development, studies how a fertilized egg gives rise to an organism with differentiated tissues, a body plan, and functioning organs.
Developmental coordination disorder
Developmental coordination disorder (DCD, dyspraxia) is a neurodevelopmental motor disorder affecting about 5% of children, diagnosed by DSM-5 criteria, assessed with MABC-2/BOT-2, treated with task-oriented interventions, and lifelong in course.
Developmental delay-ataxia-hypotonia-facial dysmorphism syndrome
Developmental delay-ataxia-hypotonia-facial dysmorphism syndrome, better known as HADDS or EBF3 neurodevelopmental disorder, is a rare autosomal dominant neurodevelopmental disorder caused by EBF3 gene variants, marked by low muscle tone, ataxia, and speech delay.
Developmental delay-cervical spine anomalies-facial dysmorphism-intellectual disability syndrome
Developmental delay-cervical spine anomalies-facial dysmorphism-intellectual disability syndrome, or Al Kaissi syndrome (OMIM 617694), is a rare autosomal recessive CDK10 disorder with growth retardation, cervical vertebral segmentation defects, and intellectual disability.
Developmental disability
Developmental disability: group of conditions impairing physical, learning, language, or behavior areas beginning in childhood; also called developmental disorders. About 1 in 6 US children affected; includes ADHD, autism, cerebral palsy; shaped by DD Act, IDEA, ADA.
Developmental dysplasia of hip
Developmental dysplasia of the hip (DDH), formerly congenital dislocation of the hip, is a spectrum of infant hip abnormalities from instability to dislocation; screened by Ortolani and Barlow maneuvers and ultrasound, treated early with the Pavlik harness.
Developmental glaucoma
Developmental glaucoma, chiefly primary congenital glaucoma (PCG), is childhood glaucoma from abnormal trabecular meshwork and angle development causing elevated IOP; genes CYP1B1, LTBP2, TEK; treated surgically.
Developmental neuroscience
Developmental neuroscience studies how nervous systems develop across invertebrate, vertebrate, and human stages; its flagship journal, Developmental Neuroscience (Dev Neurosci, ISSN 0378-5866), was founded 1978 by Karger in Switzerland, now published by Oxford University Press.
Developmental odontogenic cysts
Developmental odontogenic cysts (ICD-11 DA05.0) are epithelium-lined jaw cysts arising from tooth-forming tissue remnants, including dentigerous cyst, odontogenic keratocyst, calcifying and glandular odontogenic cysts, lateral periodontal and gingival cysts, classified by the WHO 2022 edition.
