The Divje Babe flute, also sometimes called the tidldibab or Neanderthal flute, is the femur of a cave bear, which is pierced by spaced holes similar to those found on a flute. The object was unearthed at Divje Babe I, a cave site near Cerkno in northwestern Slovenia in 1995, during systematic archaeological excavations in the area. It is possible that it was made by Neanderthals as a form of musical instrument, although this theory is debated by scientists: some argue that the holes in the bone were artificially made by Neanderthals, while others say they were made by carnivores. If confirmed as a musical instrument, it would be the oldest-known Paleolithic flute and musical instrument. The object is now in the collection of the National Museum of Slovenia in Ljubljana.

La Fuensanta is a portrait painting by Spanish artist Julio Romero de Torres depicting Maria Teresa López González, one of his models. The painting was made in the autumn of 1929, when Torres completed another two artworks, La Chiquita Piconera and Bodegas Cruz Conde. González was one of Torres's favourite models, having first sat for him at the age of fourteen. According to Sotheby's, the work has been "proclaimed as a quintessential rendition of Andalucian beauty", and it was depicted for 25 years on the 100 peseta banknote. The work was exhibited at the Ibero-American Exposition in Seville in 1930, and is now in a private collection. Painting credit: Julio Romero de Torres

The Palácio Rio Negro is a palace in Petrópolis in the state of Rio de Janeiro, Brazil. One of the official residences of the president of Brazil, it is used mainly as a country retreat. The palace was designed by the Italian architect Antonio Jannuzzi in 1889 and built in the same year as a summer residence for Manuel Gomes de Carvalho, Baron of Rio Negro. He moved to Paris in 1894, leaving the building empty, and in February 1896 the palace and adjacent buildings were sold to the state of Rio de Janeiro to serve as the official residence of the state governor. It was then acquired by the federal government of Brazil in 1903, becoming the official presidential summer residence. This photograph depicts the façade of the Palácio Rio Negro in 2015.

The General is a 1926 American silent film released by United Artists. It was inspired by the Great Locomotive Chase, a true story of an event that occurred during the American Civil War. The story was adapted from the 1889 memoir The Great Locomotive Chase by William Pittenger. The film stars Buster Keaton in the leading role; Keaton co-directed it with Clyde Bruckman. The General was not well received by critics or audiences at the time of its release, but it has since been reevaluated and is now often ranked among the greatest American films.

The Belle Tout Lighthouse is a decommissioned lighthouse and British landmark located at Beachy Head, East Sussex, close to the town of Eastbourne. The cliffs near Beachy Head saw numerous shipwrecks in the 17th and early 18th centuries and a petition to erect a lighthouse started around 1691. Despite this, the lighthouse was not built until 1828, initially as a temporary wooden structure, and then as a permanent granite lighthouse which was designed by Thomas Stevenson and became operational in 1834. The light was provided by a three-sided rotating array of oil lamps with ten lamps on each side, each lamp mounted within a parabolic reflector. The Belle Tout lighthouse was decommissioned in 1902, when the replacement Beachy Head Lighthouse was built at the bottom of the cliffs. In 1999, the Grade II listed building was moved in one piece to prevent it from succumbing to coastal erosion, and since 2010 it has operated as a bed and breakfast. Photograph credit: Kallerna

Alsace–Lorraine, now known as Alsace–Moselle, is a historical region in modern-day France. It was created by the German Empire in 1871, after it had seized the region from France in the Franco-Prussian War with the Treaty of Frankfurt and forced France to pay an indemnity of five billion francs. Anger in the French Third Republic about the loss of the territory was one of the contributing factors that led to World War I, and the region reverted to France in 1918 as part of the Treaty of Versailles and Germany's defeat in the war. This oil-on-canvas painting, titled The Geography Lesson or The Black Spot, was painted around 1887 by Albert Bettannier. It depicts a school teacher showing pupils a map of France in which Alsace–Lorraine is coloured black, portraying French resentment of the loss of the region to Germany. The painting is in the collection of the German Historical Museum in Berlin. Painting credit: Albert Bettannier

Kumquats are a group of small fruit-bearing trees in the flowering plant family Rutaceae. Their taxonomy is disputed. They were previously classified as forming the now-historical genus Fortunella or placed within the genus Citrus, sensu lato. Different classifications have alternatively assigned them to anywhere from a single species, C. japonica, to numerous species representing each cultivar. This photograph, depicting one halved and two whole kumquats, was focus-stacked from 22 separate images. Photograph credit: Ivar Leidus

Sándor Vay (1859–1918) was a Hungarian poet and journalist. Born as a female named Sarolta, Vay was one of the first Hungarian women to complete university studies. Vay then began identifying as a male journalist, both before and after the sensational trial for his marriage to another woman in 1889. The case drew the attention of noted sexologists of the period, including Havelock Ellis and Richard von Krafft-Ebing, who used it to explore female inversion in the emerging field of sexology. During his lifetime, he was well respected as an author of historical articles on notable figures and cultural topics related to Hungary. Many of his works have been posthumously republished and are considered an important part of his country's literary heritage. Unknown author; restored by Adam Cuerden

The Sleeping Gypsy is an 1897 oil-on-canvas by the French Naïve artist Henri Rousseau. It is a fantastical depiction of a lion musing over a sleeping woman on a moonlit night. Rousseau first exhibited the painting at the 13th Salon des Indépendants, and tried unsuccessfully to sell it to the mayor of his hometown, Laval. It instead entered the private collection of a Parisian charcoal merchant, where it remained until 1924, when it was discovered by the art critic Louis Vauxcelles. The Paris-based art dealer Daniel-Henry Kahnweiler purchased the painting in 1924, although a controversy arose over whether the painting was a forgery. It was acquired by art historian Alfred H. Barr Jr. for the Museum of Modern Art in New York, where it remains. Painting credit: Henri Rousseau

Vanadinite is a mineral belonging to the apatite group of phosphates. It is one of the main industrial ores of the metal vanadium and a minor source of lead. A dense, brittle mineral, it is usually found in the form of red hexagonal crystals. It is an uncommon mineral, formed by the oxidation of lead ore deposits such as galena. First discovered in 1801 in Mexico, vanadinite deposits have since been unearthed in South America, Europe, Africa, and North America. This cluster of reddish brown tabular vanadinite crystals, measuring 4.0 cm × 2.5 cm × 2.3 cm (1.57 in × 0.98 in × 0.91 in), was found in a mine in Mibladen, Morocco. The photograph was focus-stacked from 212 separate images using software. Photograph credit: Ivar Leidus

Thyroid hormones are hormones produced and released by the thyroid gland, namely triiodothyronine (T3) and thyroxine (T4). They are tyrosine-based hormones that are primarily responsible for regulation of metabolism. T3 and T4 are partially composed of iodine, derived from food. A deficiency of iodine leads to decreased production of T3 and T4, enlarges the thyroid tissue and will cause the disease known as simple goitre. This illustration shows the synthesis of thyroid hormones, as seen on an individual thyroid follicular cell. Illustration credit: Mikael Häggström

The Eurasian brown bear (Ursus arctos arctos) is one of the most common subspecies of the brown bear, and is found in much of Eurasia. It is also called the European brown bear, common brown bear, common bear, and colloquially by many other names. The genetic diversity of present-day brown bears (Ursus arctos) has been extensively studied over the years and appears to be geographically structured into five main clades based upon analysis of the mitochondrial DNA. This adult female was photographed near Stari Kot, Slovenia. Photograph credit: Charles J. Sharp

Valerian (Valeriana officinalis) is a perennial flowering plant in the family Caprifoliaceae, native to Europe and Asia. In the summer when the mature plant may have a height of 1.5 metres (5 feet), it bears sweetly scented pink or white flowers that attract many fly species, especially hoverflies of the genus Eristalis. Valerian has been used as a herb in traditional medicine since at least the time of ancient Greece and Rome; Hippocrates described its properties and Galen later prescribed it as a remedy for insomnia. This valerian flower was photographed in Niitvälja, Estonia, in 2021. Photograph credit: Ivar Leidus
