Norfolk Ridge, also known as Norfolk Ridge Seamount, is an underwater geological feature in the South Pacific Ocean. It is primarily located northeast of New Zealand and is considered part of the larger New Zealand region in the Pacific. The ridge consists of a series of seamounts and underwater ridges, which are formed by volcanic activity. The area is of interest for various scientific studies, including marine biology and geology, as it hosts unique ecosystems and geological formations.
Rinner Trough is a geological feature located in Antarctica, specifically in the eastern part of the continent. It is characterized as a deep, linear depression or trough that is often associated with glacial and tectonic processes. The Rinner Trough is part of the broader contextual landscape of Antarctica, influenced by the region's unique geological history, including its ice-sheet dynamics, sediment deposition, and tectonic activity.
Rungapapa Knoll is a notable geographical feature located in Antarctica, specifically in the vicinity of the Antarctic Peninsula. It is characterized as a prominent knoll, which is a small hill or mound. The feature is part of the rugged terrain of the Antarctic region, which includes various other landforms such as mountains, glaciers, and icebergs.
The "Three Wise Men" refers to a group of three volcanic mountains located in the Caribbean, specifically on the island of Saint Lucia. These volcanoes are named: 1. **Mount Gros Piton** 2. **Mount Petit Piton** 3. **Soufrière Volcano** The "Three Wise Men" are well-known for their striking appearances and their roles in the landscape of Saint Lucia.
Tourmaline Reef is a popular surf spot located in La Jolla, California, known for its consistent waves and picturesque setting. It is part of La Jolla's coastline and attracts surfers, paddleboarders, and marine life enthusiasts. The reef is named for the colorful tourmaline gemstones that can sometimes be found in the area. The spot is characterized by its relatively shallow waters and often provides suitable conditions for both beginners and experienced surfers, depending on the swell and tide.
Wedi Ireng Beach is a scenic beach located in the eastern part of Indonesia, specifically on the island of Java in the region of Banyuwangi. It is known for its stunning natural beauty, featuring fine white sand, clear blue waters, and lush green hills surrounding the area. The beach is often praised for its picturesque landscapes, making it a popular destination for both local and international tourists.
Yuryaku Seamount is an underwater mountain located in the northwestern Pacific Ocean, part of the volcanic arc system associated with the Kamchatka Peninsula and the Kuril Islands. It is one of several seamounts in the region, which are often formed by volcanic activity. Seamounts like Yuryaku are significant for marine biodiversity, as they provide habitats for various marine organisms and can influence local ocean currents and ecosystems.
Lanai is the sixth-largest island in Hawaii and is known for its stunning natural beauty, luxury resorts, and relatively low population density. Often referred to as the "Pineapple Island," Lanai was formerly a major producer of pineapples, with a significant portion of its economy based on pineapple cultivation until the late 20th century. The island features diverse landscapes, including rugged volcanic terrain, lush rainforests, and beautiful beaches.
Maro Reef is a marine protected area located off the coast of the province of Granada in Spain. It is situated near the town of Maro, which is part of the municipality of Nerja. The reef is known for its rich biodiversity, including various species of fish, corals, and other marine life. The area also features underwater caves and cliffs, making it a popular spot for activities such as snorkeling and diving.
Bestrophin 1 (BEST1) is a protein that is encoded by the BEST1 gene in humans. It is primarily expressed in retinal cells, particularly in the retinal pigment epithelium (RPE), and plays an important role in the function of the retina. Bestrophin 1 is believed to be involved in the regulation of ion channels, particularly chloride channels, and is thought to have a role in maintaining the ionic balance and fluid homeostasis in the eye.
CACNA2D3 is a gene that encodes the alpha-2/delta-3 subunit of voltage-gated calcium channels. These channels are critical for various physiological processes, including muscle contraction, neurotransmitter release, and other signal transduction pathways. The alpha-2/delta subunits play a role in the trafficking, expression, and regulation of the calcium channels.
GABRA3 is a gene that encodes the gamma-aminobutyric acid (GABA) type A receptor subunit alpha3. GABA receptors are the major inhibitory neurotransmitter receptors in the central nervous system (CNS) and play a crucial role in regulating neuronal excitability and synaptic transmission. The GABRA3 protein is part of the pentameric structure that forms the GABA A receptor, which consists of five subunits.
HCN2 refers to a member of the hyperpolarization-activated cyclic nucleotide-gated (HCN) channel family, specifically the HCN2 gene that encodes for the HCN2 protein. HCN channels are ion channels that allow the selective passage of sodium (Na⁺) and potassium (K⁺) ions across cell membranes.
KCNA2 (Potassium Voltage-Gated Channel Subfamily A Member 2) is a gene that encodes a protein known as a voltage-gated potassium channel. These channels play a crucial role in maintaining the electrical excitability of cells, particularly in neurons and muscle cells. The KCNA2 protein is involved in repolarizing the membrane potential after an action potential, helping to regulate the flow of potassium ions across the cell membrane.
KcsA is a potassium ion (K⁺) channel derived from the bacterium *Streptomyces lividans*. It is one of the first potassium channels to be structurally characterized, providing significant insights into the mechanism of ion selectivity and channel function in biological systems. KcsA is a homotetrameric protein, meaning it is composed of four identical subunits that together form a central pore through which potassium ions can pass.
LRRC8B (Leucine-Rich Repeat Containing 8 Isoform B) is a protein that is part of the LRRC8 family of proteins, which are known to form channels in cell membranes. These channels are important for the transport of various molecules across cell membranes, particularly small metabolites, ions, and water. LRRC8B is specifically involved in forming volume-regulated anion channels (VRACs), which are related to cell volume regulation.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
