An aerial view of Ma'aleh Akrabim (Scorpions Pass), part of Israel's Route 227. This steep, twisted road is considered dangerous owing to its poor physical condition. Below the pass there is a dropoff of hundreds of metres, yet the road has no guard rails.Photo: אילן ארד
Mehmed VI (1861–1926) was the 36th and last Sultan of the Ottoman Empire. He was girded with the Sword of Osman in June 1918, with his reign beginning the following month after his brother's death. Following the Ottoman defeat in World War I, Mehmed VI was tasked with reconciliation with the Allies. However, his settlements were denounced by Turkish nationalists, and in 1922 the Grand National Assembly of Turkey abolished the sultanate. Mehmed VI spent the rest of his life in exile.Photo: Sébah & Joaillier; restoration: Adam Cuerden
The marsh frog (Pelophylax ridibundus) is a species of true frog and the largest frog native to Europe; females of this sexually dimorphic species may be up to 17 centimetres (6.7 in) long. The marsh frog feeds mainly on insects, but it also eats smaller amphibians, fish, and rodents.Photo: Marie-Lan Nguyen
The bush cockroach (Ellipsidion australe) is a cockroach of the order Blattodea, of which about 30 species out of 4,600 total are associated with human habitats. Living in a wide range of environments around the world, cockroaches are among the hardiest insects, capable of remaining active for a month without food and able to survive on limited resources.Photograph: Cyron Ray Macey
The white-necked petrel (Pterodroma cervicalis) is a seabird in the family Procellariidae; adults measure some 43 centimetres (17 in) in length, with a wingspan of 95–105 centimetres (37–41 in). Although the species is found in much of the South Pacific, it breeds on only three islands and is thus considered vulnerable by the IUCN.Photograph: JJ Harrison
The soursop is the fruit of Annona muricata, an evergreen from Central and South America adapted to areas of high humidity and relatively warm winters. The taste has been described as a combination of strawberry and pineapple, with sour citrus flavour notes contrasting with an underlying creamy flavour reminiscent of coconut or banana.Photograph: Muhammad Mahdi Karim
Rainy Season in the Tropics, an 1866 painting by the American landscape painter Frederic Edwin Church.

He traveled widely, including twice to South America (as here), but also around the Mediterranean and the Middle East.

An anatomical diagram of a hypothetical ancestral mollusc. Whether or not such a creature ever existed is a subject of debate among evolutionary biologists, but the construct or bauplan depicted here includes most of the physical attributes likely present in some form of shared molluscan ancestor, including a nervous system which is hypoathroid, an unsegmented, bilaterally symmetrical body, a single domed shell, and with organs occurring either singly or in pairs (i.e., with no metamerism).
Biologists began drawing bauplans of molluscs in the late 19th century in an attempt to summarize the common features of the molluscan phylum. As pictures, however, these illustrations sometimes may actually serve to constrain theoretical understanding rather than aid it, especially given the absence of any specific fossil evidence of such a creature having existed. Nevertheless, depictions continue to be made and revised: organs become rearranged, emphases shift and settle, and the pictures themselves become a subject of analysis (or meta-analysis) quite apart from their completeness or accuracy as scientific works.Diagram: K.D.

The grey-headed albatross (Thalassarche chrysostoma) is an albatross, averaging 81 cm (32 in) in length and 2.2 m (7.2 ft) in wingspan, which breeds further south than any other mollymawk. Though its common name derives from the species' ashy-grey head, throat and upper neck, the scientific name is a reference to the bright golden streaks on its bill.Photograph: JJ Harrison
A field of common sunflowers (Helianthus annuus) near Cardejón, Aragon, Spain. This species of sunflower, indigenous to the Americas, was brought to Europe in the 16th century and used widely (together with its oil) as a cooking ingredient, though it can also be used as bird food, as livestock forage, and in some industrial applications.Photograph: Diego Delso
"Weird Al" Yankovic (b. 1959) is an American musician known for his humorous songs which make light of popular culture and often parody specific songs by contemporary musical acts. His parodies often extend to his music videos, which may at times be scene-for-scene reinterpretations of the originals. He has won three Grammy Awards, sold more than 12 million albums between 1976 and 2007, and recorded over 150 songs.Photograph: Kyle Cassidy

The armies of the Mughal Emperor Humayun fighting those of Bahadur Shah of Gujarat in the year 1535, as depicted in an Akbarnama manuscript from the late 16th century. Bahadur, the Sultan of Gujarat, had allied with the Portuguese and planned an attack on the Mughals. To preempt such an attack, Humayun struck at Gujarat and conquered Mandu and Champaner before stopping his attack. Bahadur Shah was killed by the Portuguese two years later; Humayun was overthrown by Sher Shah Suri in 1540, retaking the throne fifteen years later.Illustration: Dharmdas, Manre Royale d’Aubusson
