The bog turtle (Glyptemys muhlenbergii) is a critically endangered species of semiaquatic turtle in the familyEmydidae. The species is endemic to the eastern United States. It was first scientifically described in 1801 after an 18th-century survey of Pennsylvania. The smallest North American turtle, its carapace measures about 10 centimeters (4 in) long when fully grown. Although the bog turtle is similar in appearance to the painted or spotted turtles, its closest relative is actually the somewhat larger wood turtle. The bog turtle can be found from Vermont in the north, south to Georgia, and west to Pennsylvania. Diurnal and secretive, it spends most of its time buried in mud and – during the winter months – in hibernation. The bog turtle is omnivorous, feeding mainly on small invertebrates. The bog turtle is the state reptile of New Jersey. (Full article...)
The snowy plover (Anarhynchus nivosus) is a small shorebird found in the Americas. It is a member of the bird family Charadriidae, which includes the plovers, dotterels, and lapwings. The snowy plover was originally described by John Cassin in 1858, but was classified as a subspecies of the Kentish plover in 1922. Since 2011, the snowy plover has been recognized as a distinct species based on genetic and anatomical differences from the Kentish plover. Two or three subspecies are recognized, distributed along the Pacific coast of North America, Ecuador, Peru, and Chile, in several inland areas of the US and Mexico, along the Gulf Coast, and on Caribbean islands. The coastal populations consist of both residential and migratory birds, whereas the inland populations are mostly migratory. It is one of the best studied endemic shorebirds of the Americas, and one of the rarest. (Full article...)

Position of the human cerebellum (sagittal view)
The cerebellum (pl.: cerebella or cerebellums; Latin for 'little brain') is a major feature of the hindbrain of all vertebrates. Although usually smaller than the cerebrum, in some animals such as the mormyridfishes it may be as large as it or even larger. In humans, the cerebellum plays an important role in motor control and cognitive functions such as attention and language as well as emotional control such as regulating fear and pleasure responses, but its movement-related functions are the most solidly established. The human cerebellum does not initiate movement, but contributes to coordination, precision, and accurate timing: it receives input from sensory systems of the spinal cord and from other parts of the brain, and integrates these inputs to fine-tune motor activity. Cerebellar damage produces disorders in fine movement, equilibrium, posture, and motor learning in humans. (Full article...)

The white stork (Ciconia ciconia) is a large bird in the stork family, Ciconiidae. Its plumage is mainly white, with black on the bird's wings. Adults have long red legs and long pointed red beaks, and measure on average 100–115 cm (39–45 in) from beak tip to end of tail, with a 155–215 cm (61–85 in) wingspan. The two subspecies, which differ slightly in size, breed in Europe north to Finland, northwestern Africa, Palearctic east to southern Kazakhstan and southern Africa. The white stork is a long-distance migrant, wintering in Africa from tropical Sub-Saharan Africa to as far south as South Africa, or on the Indian subcontinent. When migrating between Europe and Africa, it avoids crossing the Mediterranean Sea and detours via the Levant in the east or the Strait of Gibraltar in the west, because the air thermals on which it depends for soaring do not form over water.

The asteroids of the inner Solar System and Jupiter: the belt is located between the orbits of Jupiter and Mars. The asteroid belt is a torus-shaped region in the Solar System, centered on the Sun and roughly spanning the space between the orbits of the planets Jupiter and Mars. It contains a great many solid, irregularly shaped bodies called asteroids or minor planets. The identified objects are of many sizes, but much smaller than planets, and, on average, are about one million kilometers (or six hundred thousand miles) apart. This asteroid belt is also called the main asteroid belt or main belt to distinguish it from other asteroid populations in the Solar System. (Full article...)
The first homosexual movement thrived in Germany from the late nineteenth century until 1933. The movement began in Germany because of a confluence of factors, including the criminalization of sex between men (Paragraph 175) and the country's relatively lax censorship. German writers in the mid-nineteenth century coined the word homosexual and criticized its criminalization. In 1897, Magnus Hirschfeld founded the world's first homosexual organization, the Scientific-Humanitarian Committee, whose aim was to use science to improve public tolerance of homosexuality and repeal Paragraph 175. During the German Empire, the movement was restricted to the wealthy elite, but it greatly expanded in the aftermath of World War I and the German Revolution. (Full article...)

The sarcophagus ofEshmunazar II is a 6th-century BC sarcophagus unearthed in 1855 in the grounds of an ancient necropolis southeast of the city of Sidon, in modern-day Lebanon, that contained the body of Eshmunazar II (Phoenician: 𐤀𐤔𐤌𐤍𐤏𐤆𐤓ʾšmnʿzr, r. c. 539 – c. 525 BC), PhoenicianKing of Sidon. One of only three Ancient Egyptian sarcophagi found outside Egypt – the other two belonged to Eshmunazar's father King Tabnit and to a woman, possibly Eshmunazar's mother Queen Amoashtart – it was likely carved in Egypt from local amphibolite, and captured as booty by the Sidonians during their participation in Cambyses II's conquest of Egypt in 525 BC. The sarcophagus has two sets of Phoenician inscriptions, one on its lid and a partial copy of it on the sarcophagus trough, around the curvature of the head. The lid inscription was of great significance upon its discovery, as it was the first Phoenician language inscription to be discovered in Phoenicia proper and the most detailed Phoenician text ever found anywhere up to that point, and is today the second longest extant Phoenician inscription, after the Karatepe bilingual.

Paxillus involutus, also known as the brown roll-rim or the common roll-rim, is a species of basidiomycete fungus. Although it has gills, it is more closely related to the pored boletes than to typical gilled mushrooms. It was first described by Pierre Bulliard in 1785, and was given its current binomial name by Elias Magnus Fries in 1838. Genetic testing suggests that Paxillus involutus may be a species complex rather than a single species. Various shades of brown in colour, the fruit body grows up to 6 cm (2+3⁄8 in) high and has a funnel-shaped cap up to 12 cm (4+3⁄4 in) wide with a distinctive inrolled rim and decurrent gills that may be pore-like close to the stipe.

Biology is the scientific study of life and living organisms. It is a broad natural science that encompasses a wide range of fields and unifying principles that explain the structure, function, growth, origin, evolution, and distribution of life. Central to biology are five fundamental themes: the cell as the basic unit of life, genes and heredity as the basis of inheritance, evolution as the driver of biological diversity, energy transformation for sustaining life processes, and the maintenance of internal stability (homeostasis).

A plot of normal distribution (or bell-shaped curve) where each band has a width of 1 standard deviation – See also: 68–95–99.7 rule. In statistics, the standard deviation is a measure of the amount of variation of the values of a variable about its mean. A low standard deviation indicates that the values tend to be close to the mean (also called the expected value) of the set, while a high standard deviation indicates that the values are spread out over a wider range. The standard deviation is commonly used in the determination of what constitutes an outlier and what does not. Standard deviation may be abbreviated SD or std dev, and is most commonly represented in mathematical texts and equations by the lowercase Greek letterσ (sigma), for the population standard deviation, or the Latin letters, for the sample standard deviation.

Sci-Hub is a shadow library that provides free access to millions of research papers, regardless of copyright, by bypassing publishers' paywalls in various ways. Unlike Library Genesis, it does not provide access to books. Sci-Hub was founded in Kazakhstan by Alexandra Elbakyan in 2011, in response to the rising costs of research papers behind paywalls. The site is extensively used worldwide. In September 2019, the site's operator(s) said that it served approximately 400,000 requests per day. In addition to its intensive use, Sci-Hub stands out among other shadow libraries because of its easy use/reliability and because of the enormous size of its collection; a 2018 study estimated that Sci-Hub provided access to most of the scholarly publications with issued DOI numbers. On 15 July 2022, Sci-Hub reported that its collection comprised 88,343,822 files. Since December 2020, the site has paused uploads due to legal troubles. (Full article...)
Personification of Music by Antonio Franchi, c. 1650 Anthropomorphism (from the Greek words "ánthrōpos" (ἄνθρωπος), meaning "human," and "morphē" (μορφή), meaning "form" or "shape") is the attribution of human form, character, or attributes to non-human entities. It is considered to be an innate tendency of human psychology. Personification is the related attribution of human form and characteristics to abstract concepts such as nations, emotions, and natural forces, such as seasons and weather. Both have ancient roots as storytelling and artistic devices, and most cultures have traditional fables with anthropomorphized animals as characters. People have also routinely attributed human emotions and behavioral traits to wild as well as domesticated animals. (Full article...)

In biology, taxonomy (from Ancient Greekτάξις (taxis)'arrangement' and -νομία (-nomia)'method') is the scientific study of naming, defining (circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon), and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum (division is sometimes used in botany in place of phylum), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, having developed a ranked system known as Linnaean taxonomy for categorizing organisms.
