The green hairstreak (Callophrys rubi) is a small butterfly in the family Lycaenidae. It has a wingspan reaching about 26–30 millimetres (1.0–1.2 in) in length. The overside of the wings is a uniform dull brown, with two paler patches on the male's forewings made up of scent scales. The underside is bright green, with a thin white line that is often reduced to a faint row of dots or even missing altogether. The iridescent green colour of the underside is a structural colour caused by the diffraction and interference of light by microscopic repeating structures forming a diffraction grating in the wing scales. Green hairstreaks can be found at the end of March, with their flight time usually lasting until the end of June, but they are sometimes seen in July and early August. They never rest with their wings open, to maintain their green camouflage. The males exhibit territorial behaviour.
The Mystical Nativity is an oil-on-canvas painting by the Italian Renaissance master Sandro Botticelli, dated around 1500 to 1501. It is his only signed work and has unusual iconography for a painting of the Nativity. The Virgin Mary is shown kneeling before the Christ Child in the centre, in the presence of the shepherds and wise men who are visiting him. At the bottom of the work, three angels embrace three men, seeming to raise them up from the ground, while seven devils behind them flee to the underworld. In Renaissance times, paintings of the Last Judgement showed viewers the reckoning of the damned and the saved at the time of Christ's Second Coming. According to art historian Jonathan Nelson, "in echoing this kind of painting the Mystical Nativity is asking us to think not only of Christ's birth but of his return".
The Greek inscription at the top of the work, referencing the Book of Revelation, translates as: 'This picture, at the end of the year 1500, in the troubles of Italy, I, Alessandro, in the half-time after the time, painted, according to the eleventh [chapter] of Saint John, in the second woe of the Apocalypse, during the release of the devil for three and a half years; then he shall be bound in the twelfth [chapter] and we shall see [him buried] as in this picture'. It has been suggested that the work may be connected with the influence of the fanatical preacher Girolamo Savonarola, who was active in Florence at the time and whose influence appears in a number of late paintings by Botticelli. The painting is in the collection of the National Gallery in London.Painting credit: Sandro Botticelli
Allen Ginsberg (June 3, 1926 – April 5, 1997) was an American poet, philosopher and writer. He is considered to be one of the leading figures of both the Beat Generation during the 1950s and the counterculture that soon followed. Ginsberg vigorously opposed militarism, economic materialism and sexual repression; he was also known to embody various aspects of this counterculture, such as his views on drugs, hostility to bureaucracy and openness to Eastern religions. He was one of many influential American writers of his time who were associated with the Beat Generation, including Jack Kerouac and William S. Burroughs. Ginsberg is best known for his poem "Howl", in which he denounced what he saw as the destructive forces of capitalism and conformity in the United States.
The Portrait of Marchesa Brigida Spinola-Doria is an oil-on-canvas painting by Flemish artist Sir Peter Paul Rubens, dating to 1606. It was commissioned by Marchese Giacomo Massimiliano Doria of Genoa and depicts his wife, Marchesa Brigida, shortly after their wedding in 1605. Both the Marchese and the Marchesa were members of prominent families: the Doria and the Spinola, respectively. In the painting, the Marchesa is shown in an opulent setting to convey luxury; adorned with jewels, she wears a satin and lace dress, with a broad ruff around her neck. Lighting is used to emphasise the drapery of her bulky wedding gown, while she looks down on the viewer, establishing the necessity to hang the finished portrait above the height of viewers. It has been trimmed several times on each side, removing the garden shown in the background and the lower part of the figure, including the bottom of the Marchesa's floor-length gown. The painting, part of the Samuel H. Kress Collection, now hangs in the National Gallery of Art in Washington, D.C.Painting credit: Peter Paul Rubens
The European paper wasp (Polistes dominula or Polistes dominulus) is one of the most common species of wasps in the genus Polistes. Originally described in 1791 by German naturalist Johann Ludwig Christ as Vespa dominula, it is native to southern Europe and North Africa, as well as temperate parts of Asia as far east as China. It has also been introduced to Australia, New Zealand, South Africa and the Americas. The species is common and cosmopolitan due to its exceptional survival features, such as a productive colony cycle, a short development time and a higher ability to endure predator attacks. It generally lives in temperate, terrestrial habitats, such as chaparral, forest and grassland biomes.

The Alba Madonna is an oil painting by the Italian High Renaissance artist Raphael, produced around 1510. A circular piece, it depicts the Virgin Mary, the Christ Child and a young John the Baptist in a typical Italian countryside. John is holding up a cross to Jesus, which the latter is grasping. All three figures are staring at the cross. They are grouped to the left of the round design, but Mary's outstretched arm and billowing cloak balance the image. Originally painted on a circular wooden panel, the painting was transferred to a square canvas in the early nineteenth century, while in the collection of the Hermitage Museum in Saint Petersburg. Through analysis of the painting, it has been determined that the original panel was severely splitting down the center and on the right side. The landscape on the far right of the work was damaged during the transfer process. The painting is now in the permanent collection of the National Gallery of Art in Washington, D.C.Painting credit: Raphael
Millicent Fawcett (11 June 1847 – 5 August 1929) was a British intellectual, political leader, activist and writer, known primarily for her work as a campaigner for women's suffrage. She took a moderate line regarding women's rights but was a tireless campaigner. In 1897 she became the president of the National Union of Women's Suffrage Societies, a position she held until 1919. She placed much of her focus on improving women's opportunities for higher education and served as a governor of Bedford College, London (now part of Royal Holloway), as well as co-founding Newnham College, Cambridge. As a politician, Fawcett was appointed to lead the British government's commission to South Africa in July 1901, investigating conditions in the concentration camps that had been created there in the wake of the Second Boer War. Her report corroborated what campaigner Emily Hobhouse had said about the terrible conditions in the camps.

Manuel Osorio Manrique de Zúñiga, also known as the "Red Boy", is an oil-on-canvas portrait by Spanish artist Francisco Goya, produced in 1787–88. It was commissioned by Vicente Joaquín Osorio de Moscoso, conde de Altamira, who had hired Goya to paint several family portraits. The eponymous subject of the painting is Altamira's youngest son, Manuel, who was born in April 1784 and later died aged eight in June 1792. He is depicted in a red costume, holding a string attached to his pet magpie, with Goya's visiting card in its beak. On Manuel's left is a cage of finches, while three cats intently watch the magpie on his right, which may symbolize the innocent soul and evil forces, respectively. The painting now hangs in the Metropolitan Museum of Art in New York, part of the Jules Bache Collection.Painting credit: Francisco Goya
Stellagama stellio, also known as the starred agama or the roughtail rock agama, is a species of agamid lizard, the only member of the monotypic genus Stellagama. The species can be found in Greece, western Asia and northern Egypt; it has also been introduced to Malta. It can reach a total length of 35 centimetres (14 in) or slightly longer. Like many agamids, the species can change its colour to express its mood. It basks on stone walls, rocks and trees. The species is usually found in rocky habitats and is quite shy, being very ready to dive into cracks to hide from potential predators.
A binary black hole is a system consisting of two black holes in close orbit around each other. For many years, proving the existence of such binaries was made difficult because of the nature of black holes themselves and the limited means of detection available. However, in the event that a pair of black holes were to merge, an immense amount of energy should be given off as gravitational waves, with distinctive waveforms that can be calculated using general relativity.
This video is a computer simulation of the binary black hole system GW150914 during its final inspiral, merge and ringdown, as it would have been seen by a nearby observer. The star field behind the black holes is heavily distorted and appears to rotate and move, due to extreme gravitational lensing caused by spacetime being warped by the orbiting black holes. This event, observed by LIGO in 2015, was the first observation of a binary black hole merger, as well as the first direct detection of gravitational waves, confirming Einstein's predictions.Video credit: Simulating eXtreme Spacetimes
Barbara McClintock (June 16, 1902 – September 2, 1992) was an American scientist and one of the world's most distinguished cytogeneticists. After receiving her PhD in botany from Cornell University in 1927, McClintock began studying chromosomes and how they change during reproduction in maize. She developed the technique for visualizing maize chromosomes and used microscopic analysis to demonstrate many fundamental genetic ideas. One of these was the notion of genetic recombination by crossing over during meiosis – a mechanism by which chromosomes exchange information. McClintock produced the first genetic map for maize, linking regions of the chromosome to physical traits. She also demonstrated the role of the telomere and the centromere, regions of the chromosome that are important in the conservation of genetic information. Recognized as among the best in the field, she received the 1983 Nobel Prize in Physiology or Medicine.
Christ in the Desert is an 1872 oil-on-canvas painting by Russian artist Ivan Kramskoi, reflecting the temptation of Christ. This theme had attracted Kramskoi since the early 1860s, when he made the first sketch of the composition. The first version of the painting is dated 1867, but turned out to be unsuccessful. In the revised version, he opted for a horizontal rather than vertical format and introduced the pallid rocky desert in the background. Kramskoi used primarily cool colours to reflect the chill dawn in the background; the thoughtful figure of Christ, wearing a dark wrap with a red tunic underneath, is slightly shifted to the right of centre. He wrote: "To the question 'this is not Christ, how do you know he looked like that?', I permitted myself to reply 'but even the actual, living Christ has not been recognised'." The painting is in the collection of the Tretyakov Gallery in Moscow.Painting credit: Ivan Kramskoi

The Yugoslav dinar was the currency of the three Yugoslav states: the Kingdom of Yugoslavia, the Socialist Federal Republic of Yugoslavia and the Federal Republic of Yugoslavia (Serbia and Montenegro), between 1918 and 2006. It was subdivided into 100 para. The currency was inaugurated in 1918, with the establishment of the Kingdom of Serbs, Croats and Slovenes, replacing the Serbian dinar. In the early years, it circulated alongside the Yugoslav krone, the successor of the Austro-Hungarian krone. In the early 1990s, the currency was subject to what has been described as the worst hyperinflation in history, as economic mismanagement made the government bankrupt and forced it to take money from the savings of the country's citizens. Inflation rates reached over one billion per cent per year, which led to five revaluations of the currency between 1990 and 1994. In total, there were eight distinct dinari, six of which were given distinguishing names and separate ISO 4217 codes.
This picture shows the obverse (top) and reverse (bottom) sides of a ten-dinara banknote of the Kingdom of Serbs, Croats and Slovenes, dated 1920. It was engraved and printed by the American Bank Note Company. The obverse features an allegory engraved by Robert Savage, entitled "Progress".Banknote credit: American Bank Note Company; imaged by Andrew Shiva
The polar bear (Ursus maritimus) is a hypercarnivorous bear whose native range lies largely within the Arctic Circle, encompassing the Arctic Ocean, its surrounding seas and surrounding land masses. A boar (adult male) weighs around 350–750 kilograms (770–1,650 lb), while a sow (adult female) is about half that size. Polar bears are the largest land carnivores currently in existence, rivalled only by the omnivorous Kodiak bear. Although it is the sister species of the brown bear, it has evolved to occupy a narrower ecological niche, with many body characteristics adapted for cold temperatures, for moving across snow, ice and open water, as well as for hunting seals, which make up most of its diet. Although most polar bears are born on land, they spend most of their time on sea ice. The species's scientific name, which is derived from this fact, means 'maritime bear'. Because of their dependence on sea ice, polar bears are categorized as marine mammals. Due to expected habitat loss caused by global warming, the polar bear is classified as a vulnerable species. For decades, large-scale hunting raised international concern for the future of the species, but populations have rebounded after controls and quotas began to take effect.
The Royal Mail is a postal service and courier company in the United Kingdom, originally established in 1516 when Henry VIII created a "Master of the Posts" position. For most of its history the Royal Mail has been a public service, operating as a government department or a state-owned enterprise. It was privatised in 2013 when a majority of its shares were floated on the London Stock Exchange. The Royal Mail owns and maintains the UK's distinctive red pillar boxes, first introduced in 1852, many of which bear the initials of the monarch. The company's subsidiary, Royal Mail Group Limited, operates the brands Royal Mail and Parcelforce Worldwide, which process letters and parcels respectively. General Logistics Systems, an international logistics company, is a wholly owned subsidiary of the Royal Mail Group.
Glacier Point is a viewpoint above Yosemite Valley in the U.S. state of California. It is located on the south wall of the valley at an elevation of 7,214 feet (2,199 m), 3,200 feet (980 m) above Half Dome Village. The point offers a superb view of several of Yosemite National Park's well-known landmarks. Between 1872 and 1968, it was the site of the Yosemite Firefall. The extreme point of the promontory of Glacier Point is wholly bare, but glacial material is abundant on the slopes below, in the hollow to the west and on the wooded slope above. Its glacial origin is definitely proved by the presence in it of rocks derived from Little Yosemite Valley and the Sierra Nevada.

Panggilan Darah (Indonesian for 'Call of Blood') is a film from the Dutch East Indies (now Indonesia), written and directed by Sutan Usman Karim and produced by Tjho Seng Han for Oriental Film. Released on 30 June 1941, the black-and-white film starred Dhalia and Soerip as orphaned sisters trying to make a living in the colonial capital of Batavia (now Jakarta) as housemaids for a man named Iskak, before moving to Kudus to work at a clove cigarette factory. They later discover that they are Iskak's nieces and are welcomed into his home. The film was shot on location at an orphanage and two factories in Central Java and was a modest commercial success in the Dutch East Indies and Singapore. The acting drew critical praise, while the soundtrack, with nine kroncong songs, was reviewed favourably. Despite this success, Oriental was unable to meet its expenses; the company merged with Multi Film soon afterwards. Panggilan Darah, which was screened as late as 1952, may now be a lost film.
