Wilmington, North Carolina once had a thriving Black middle class and an elected interracial government. In 1898 white supremacists used violence to overthrow that government, kill Black residents and drive many others from the city.

Forkhead box protein G1 is a protein that in humans is encoded by the FOXG1 gene.[5][6][7]
This gene belongs to the forkhead family of transcription factors that is characterized by a distinct forkhead domain. The complete function of this gene has not yet been determined; however, it has been shown to play a role in the development of the brain and telencephalon. Mutations of FOXG1 are the cause of FoxG1 syndrome.[8]
FOXG1 syndrome is characterized by microcephaly and brain malformations. It affects most aspects of development and can cause seizures. FOXG1 syndrome is classified as an autism spectrum disorder and was previously considered a variant of Rett syndrome.[9][10]
FOXG1 has been shown to interact with JARID1B.[11]

FOXG1 syndrome (sometimes FOXG1-related disorder) is a rare genetic disorder caused by mutation in the gene FOXG1. The main signs of this disease are: severe intellectual disability, microcephaly, epilepsy, and hyperkinetic-dyskinetic movement disorder and hypotonia with brain structure anomalies. FOXG1 syndrome is inherited in autosomal dominant fashion. The syndrome affects about 1/30 000 births, with about 1200 cases having been reported as of January 1, 2025.
The retina (from Latin rete 'net'; pl. retinae or retinas) is the innermost, light-sensitive layer of tissue of the eye. The optics of the eye create a focused two-dimensional image of the visual world on the retina, which then processes that image within the retina and sends nerve impulses along the optic nerve to the visual cortex to create visual perception. The retina serves a function that is in many ways analogous to that of the film or image sensor in a camera. The neural retina consists of several layers of neurons interconnected by synapses and is supported by an outer layer of pigmented epithelial cells. The primary light-sensing cells in the retina are the photoreceptor cells, which are of two types: rods and cones. Rods function mainly in dim light and provide monochromatic vision. Cones function in well-lit conditions and are responsible for the perception of colour through the use of a range of opsins, as well as high-acuity vision used for tasks such as reading. A third type of light-sensing cell, the photosensitive ganglion cell, is important for entrainment of circadian rhythms and reflexive responses such as the pupillary light reflex. Light striking the retina initiates a cascade of chemical and electrical events that ultimately trigger nerve impulses that are sent to various visual centres of the brain through the fibres of the optic nerve. Neural signals from the rods and cones undergo processing by other neurons, whose output takes the form of action potentials in retinal ganglion cells whose axons form the optic nerve. In vertebrate embryonic development, the retina and the optic nerve originate as outgrowths of the developing brain, specifically the embryonic diencephalon; thus, the retina is considered part of the central nervous system (CNS) and is actually brain tissue. It is the only part of the nervous system that can be visualized noninvasively. Like most of the brain, the retina is isolated from the vascular system by the blood–brain barrier. The retina is the part of the body with the greatest continuous energy demand.
Rett syndrome (RTT) is a genetic disorder that typically becomes apparent after 6–18 months of age and almost exclusively in girls. Symptoms include impairments in language and coordination, and repetitive movements. Those affected often have slower growth, difficulty walking, and a smaller head size. Complications of Rett syndrome can include seizures, scoliosis, and sleeping problems. The severity of the condition is variable. Rett syndrome is due to a genetic mutation, usually in the MECP2 gene, on the X chromosome. It almost always occurs as a new mutation, with less than one percent of cases being inherited. It occurs almost exclusively in girls; boys who have a similar mutation typically die shortly after birth. Diagnosis is based on the symptoms and can be confirmed with genetic testing. There is no known cure for Rett syndrome. Treatment is directed at improving symptoms. Anticonvulsants may be used to help with seizures. Special education, physiotherapy, and leg braces may also be useful depending on the needs of the child. Many of those with the condition live into middle age. The condition affects about 1 in 8,500 females. In 1999, Lebanese-American physician Huda Zoghbi discovered the mutation that causes the condition.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
