Members of the Academy in 1667 with Louis XIV

Science is a systematic discipline that builds and organises knowledge in the form of testable hypotheses and predictions about the universe. Modern science is typically divided into two or three major branches: the natural sciences (e.g., physics, chemistry, and biology), which study the physical world; and the behavioural sciences (e.g., economics, psychology, and sociology), which study individuals and societies. The formal sciences (e.g., logic, mathematics, and theoretical computer science), which study formal systems governed by axioms and rules, are sometimes described as being sciences as well; however, they are often regarded as a separate field because they rely on deductive reasoning instead of the scientific method or empirical evidence as their main methodology. Applied sciences are disciplines that use scientific knowledge for practical purposes, such as engineering and medicine. (Full article...)

  • Image 1 Two sheep on the shoreline of North Ronaldsay The North Ronaldsay or Orkney is a breed of sheep from North Ronaldsay, the northernmost island of Orkney, off the north coast of Scotland. It belongs to the Northern European short-tailed sheep group of breeds, and has evolved without much cross-breeding with modern breeds. It is a smaller sheep than most, with the rams (males) horned and ewes (females) mostly hornless. It was formerly kept primarily for wool, but now the two largest flocks are feral, one on North Ronaldsay and another on the Orkney island of Auskerry. The Rare Breeds Survival Trust lists the breed as a priority on its 2021–2022 watchlist, and they are in danger of extinction, with fewer than 600 registered breeding females in the United Kingdom.

  • Image 2 Tomb of Philippe Pot with life-sized hooded pleurants, c. 1477–80, now in the Louvre, Paris Funerary art is any work of art forming, or placed in, a repository for the remains of the dead. The term encompasses a wide variety of forms, including cenotaphs ("empty tombs"), tomb-like monuments which do not contain human remains, and communal memorials to the dead, such as war memorials, which may or may not contain remains, and a range of prehistoric megalithic constructs. Funerary art may serve many cultural functions. It can play a role in burial rites, serve as an article for use by the dead in the afterlife, and celebrate the life and accomplishments of the dead, whether as part of kinship-centred practices of ancestor veneration or as a publicly directed dynastic display. It can also function as a reminder of the mortality of humankind, as an expression of cultural values and roles, and help to propitiate the spirits of the dead, maintaining their benevolence and preventing their unwelcome intrusion into the lives of the living.

  • Image 3 Female near Kaktovik, Barter Island, Alaska, United States The polar bear (Ursus maritimus) is a large bear native to the Arctic and nearby areas. It is closely related to the brown bear, and the two species can interbreed. The polar bear is the largest extant species of bear and land carnivore, with adult males weighing 300–800 kg (660–1,760 lb). The species is sexually dimorphic, as adult females are much smaller. The polar bear is white- or yellowish-furred with black skin and a thick layer of fat. It is more slender than the brown bear, with a narrower skull, longer neck and lower shoulder hump. Its teeth are sharper and more adapted to cutting meat. The paws are large and allow the bear to walk on ice and paddle in the water. (Full article...)

They comprise the extant families Odobenidae (whose only living member is the walrus), Otariidae (the eared seals: sea lions and fur seals), and Phocidae (the earless seals, or true seals), with 34 extant species and more than 50 extinct species described from fossils. While seals were historically thought to have descended from two ancestral lines, molecular evidence supports them as a monophyletic group (descended from one ancestor). Pinnipeds belong to the suborder Caniformia of the order Carnivora; their closest living relatives are musteloids (weasels, raccoons, skunks and red pandas), having diverged about 50 million years ago.

  • Image 6 Ice core sample taken from drill An ice core is a core sample that is typically removed from an ice sheet or a high mountain glacier. Since the ice forms from the incremental buildup of annual layers of snow, lower layers are older than upper ones, and an ice core contains ice formed over a range of years. Cores are drilled with hand augers (for shallow holes) or powered drills; they can reach depths of over two miles (3.2 km), and contain ice up to 800,000 years old. (Full article...)

  • Image 7 Splitting of the slate blocks with hammer and chisel to produce roofing slates requires great skill. This process was not mechanised until the second half of the 20th century, and some slate is still produced in this way. These quarrymen are working at the Dinorwic Quarry, Wales, about 1910. The existence of a slate industry in Wales is attested since the Roman period, when slate was used to roof the fort at Segontium, now Caernarfon. The slate industry grew slowly until the early 18th century, then rapidly during the Industrial Revolution in Wales until the late 19th century, at which time the most important slate producing areas were in northwest Wales. These sites included the Penrhyn Quarry near Bethesda, the Dinorwic Quarry near Llanberis, the Nantlle Valley quarries, and Blaenau Ffestiniog, where the slate was mined rather than quarried. Penrhyn and Dinorwig were the two largest slate quarries in the world, and the Oakeley mine at Blaenau Ffestiniog was the largest slate mine in the world. Slate is mainly used for roofing, but is also produced as thicker slab for a variety of uses including flooring, worktops and headstones. (Full article...)

  • Image 8 An early volume of the General Stud Book, Volume 6 The Jersey Act was a regulation introduced to prevent the registration of most American-bred Thoroughbred horses in the British General Stud Book. It had its roots in the desire of British horse breeders to halt the influx of American-bred racehorses of possibly impure bloodlines during the early 20th century. Many American-bred horses were exported to Europe to race and retire to a breeding career after a number of U.S. states banned gambling, which depressed Thoroughbred racing—and thus breeding—in the United States. The loss of breeding records during the American Civil War and the late beginning of the registration of American Thoroughbreds led many in the British racing establishment to doubt that the American-bred horses were purebred.

  • Image 12 The large fruit body discovered in 2008 Phellinus ellipsoideus (formerly Fomitiporia ellipsoidea) is a species of polypore fungus in the family Hymenochaetaceae, a specimen of which produced the largest fungal fruit body ever recorded. Found in China, the fruit bodies produced by the species are brown, woody basidiocarps that grow on dead wood, where the fungus feeds as a saprotroph. The basidiocarps are perennial, allowing them to grow very large under favourable circumstances. They are resupinate, measuring 30 centimetres (12 in) or more in length, though typically extending less than a centimetre from the surface of the wood. P. ellipsoideus produces distinct ellipsoidal spores, after which it is named, and unusual setae. These two features allow it to be readily differentiated microscopically from other, similar species. Chemical compounds isolated from the species include several steroidal compounds. These may have pharmacological applications, but further research is needed. (Full article...)

Language is a structured system of communication that consists of grammar and vocabulary. It is the primary means by which humans convey meaning, both in spoken and signed forms, and may also be conveyed through writing. Human language is characterized by its cultural and historical diversity, with significant variations observed between cultures and across time. Human languages possess the properties of productivity and displacement, which enable the creation of an infinite number of sentences, and the ability to refer to objects, events, and ideas that are not immediately present in the discourse. The use of human language relies on social convention and is acquired through learning. (Full article...)

  • Integrate relatively new scientific knowledge and findings (major studies reported on by RS) into relevant articles
  • Expand 2024 in science and/or other articles for science-related topics of the year (in the box on the right)
    • Create new articles for items of this article, mostly articles relating to new scientific fields/topics/findings (the page does not use redlinks anymore but you will quickly identify possible new articles when reading it; here you can find a version with over 60 redlinked examples)
    • Some of the lists' items have not yet been integrated into their wikilinked articles; if you add a study there it should also be relevant to at least one other article
    • Maybe this could be done as part of an organized effort
  • Find[how?] studies published under a compatible open license (like CC BY 4.0) and upload the studies' images with descriptions from the study and add these images to articles if they are relevant and useful there
    • When a study with a useful image is published under an incompatible or unclear license (or the image is published not in a study but elsewhere), you could contact its authors (Twitter/Mail) and ask them to give you the permission to upload them under CC BY 4.0 (or whether they could upload the image/s under a compatible license)
    • You can also think about whether images would be useful as you read a science-related article and then search for such images:
      • if they already exist add them (if already on WMCommons) or upload them (if the license is ok) or ask their authors for permissions
      • if they don't, you could create (or request) them
