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.[page needed] Modern science is typically divided into two – or three – major branches: the natural sciences, which study the physical world, and the social sciences, which study individuals and societies. While referred to as the formal sciences, the study of logic, mathematics, and theoretical computer science are typically regarded as separate because they rely on deductive reasoning instead of the scientific method as their main methodology. Meanwhile, applied sciences are disciplines that use scientific knowledge for practical purposes, such as engineering and medicine. (Full article...)

  • Image 1 Specimen collected from the Japan Trench in 2022 Alicella gigantea is a giant, deep sea living species of amphipod. Sometimes referred to as the "supergiant amphipod", the largest of these crustaceans reach up to 34 cm (13 in) in length. The only species within the genus Alicella, it lives only at 4,850–7,000 m (15,910–22,970 ft) in depth. The species is white in colour and is distinguished from other deep-sea amphipods by minute anatomical differences, apart from size in the larger specimens. The large size of the species is often presented as an example of abyssal gigantism, though the specifics of this trait remain under investigation. Genetic studies into the species have found that it has an exceptionally large genome, which may be linked to its large body size. (Full article...)

  • Image 2 Apus is a small constellation in the southern sky. It represents a bird-of-paradise, and its name means "without feet" in Greek because the bird-of-paradise was once wrongly believed to lack feet. First depicted on a celestial globe by Petrus Plancius in 1598, it was charted on a star atlas by Johann Bayer in his 1603 Uranometria. The French explorer and astronomer Nicolas Louis de Lacaille charted and gave the brighter stars their Bayer designations in 1756. (Full article...)

  • Image 3 ☿ Mercury is the first planet from the Sun and the smallest in the Solar System. It is a rocky planet with a trace atmosphere and a surface gravity slightly higher than that of Mars. The surface of Mercury is similar to Earth's Moon, being heavily cratered, with an expansive rupes system generated from thrust faults, and bright ray systems, formed by ejecta. Its largest crater, Caloris Planitia, has a diameter of 1,550 km (960 mi), which is about one-third the diameter of the planet (4,880 km or 3,030 mi). Being the most inferior orbiting planet, it always appears close to the sun in Earth's sky, either as a "morning star" or an "evening star". It is the planet with the highest delta-v required for travel from Earth, as well as to and from the other planets in the Solar System. (Full article...)

  • Image 4 Bornean orangutan (Pongo pygmaeus) Orangutans are great apes native to the rainforests of Indonesia and Malaysia. They are now found only in parts of Borneo and Sumatra, but during the Pleistocene they ranged throughout Southeast Asia and South China. Classified in the genus Pongo, orangutans were originally considered to be one species. In 1996, they were divided into two species: the Bornean orangutan (P. pygmaeus, with three subspecies) and the Sumatran orangutan (P. abelii); a third species, the Tapanuli orangutan (P. tapanuliensis), was identified definitively in 2017. The orangutans are the only surviving members of the subfamily Ponginae, which diverged genetically from the other hominids (gorillas, chimpanzees, and humans) between 19.3 and 15.7 million years ago.

  • Image 5 Tricholoma pardinum, commonly known as spotted tricholoma, tiger tricholoma, tigertop, leopard knight, or dirty trich, is a species of gilled mushroom. First officially described by Christiaan Hendrik Persoon in 1801, it has had a confusing taxonomic history that extends over two centuries. In 1762, German naturalist Jacob Christian Schäffer described the species Agaricus tigrinus with an illustration corresponding to what is thought to be T. pardinum, and consequently, the name Tricholoma tigrinum has been used erroneously in some European field guides.

  • Image 6 The water rail, western water rail or European water rail (Rallus aquaticus) is a bird of the rail family which breeds in well-vegetated wetlands across Europe, Asia and North Africa. Northern and eastern populations are migratory, but this species is a permanent resident in the warmer parts of its breeding range. The adult is 23–28 cm (9–11 in) long, and, like other rails, has a body that is flattened laterally, allowing it easier passage through the reed beds it inhabits. It has mainly brown upperparts and blue-grey underparts, black barring on the flanks, long toes, a short tail and a long reddish bill. Immature birds are generally similar in appearance to the adults, but the blue-grey in the plumage is replaced by buff. The downy chicks are black, as with all rails. The former subspecies R. indicus has distinctive markings and a call that is very different from the pig-like squeal of the western races, and is now usually split as a separate species, the brown-cheeked rail.

  • Image 8 A scan of the first page of the notes from the interrogation of John/Eleanor Rykener at The Guildhall, London, in December 1394 – January 1395 John Rykener, also known as Eleanor, was a 14th-century sex worker arrested in December 1394 for performing a sex act with John Britby, in London's Cheapside, while wearing female attire. Although historians tentatively link Rykener, who was male, to a prisoner of the same name, the only known facts of Rykener's life come from an interrogation made by the mayor of London. Rykener was questioned on two offences: prostitution and sodomy. Prostitutes were not usually arrested in London during this period, while sodomy was an offence against morality rather than common law and so pursued in ecclesiastical courts. There is no evidence that Rykener was prosecuted for either crime. (Full article...)

  • Image 9 Dürer's Rhinoceros is the name commonly given to a woodcut executed by German artist Albrecht Dürer in 1515. Dürer never saw the actual rhinoceros, which was the first living example seen in Europe since Roman times. Instead the image is based on an anonymous written description and brief sketch of an Indian rhinoceros brought to Lisbon in 1515. Later that year, the King of Portugal, Manuel I, sent the animal as a gift for Pope Leo X, but it died in a shipwreck off the coast of Italy. Another live rhinoceros was not seen again in Europe until Abada arrived from India to the court of Sebastian of Portugal in 1577. (Full article...)

  • Image 10 Musca (Latin for 'the fly') is a small constellation in the deep southern sky. It was one of 12 constellations created by Petrus Plancius from the observations of Pieter Dirkszoon Keyser and Frederick de Houtman, and it first appeared on a celestial globe 35 cm (14 in) in diameter published in 1597 (or 1598) in Amsterdam by Plancius and Jodocus Hondius. The first depiction of this constellation in a celestial atlas was in Johann Bayer's Uranometria of 1603. It was also known as Apis (Latin for 'the bee') for 200 years. Musca remains below the horizon for most Northern Hemisphere observers. (Full article...)

  • Image 11 Agaricus deserticola, commonly known as the gasteroid agaricus, is a species of fungus in the family Agaricaceae. Formerly named Longula texensis (among several other synonyms), the fungus was transferred to the genus Agaricus in 2004 after molecular analysis showed it to be closely related to species in that genus. In 2010, its specific epithet was changed to deserticola after it was discovered that the name Agaricus texensis was illegitimate, having been previously published for a different species.

  • Image 12 Suillus pungens, commonly known as the pungent slippery jack or the pungent suillus, is a species of fungus in the genus Suillus. The fruit bodies of the fungus have slimy convex caps up to 14 cm (5.5 in) wide. The mushroom is characterized by the very distinct color changes that occur in the cap throughout development. Typically, the young cap is whitish, later becoming grayish-olive to reddish-brown or a mottled combination of these colors. The mushroom has a dotted stem (stipe) up to 7 cm (2.8 in) long, and 2 cm (0.8 in) thick. On the underside on the cap is the spore-bearing tissue consisting of minute vertically arranged tubes that appear as a surface of angular, yellowish pores. The presence of milky droplets on the pore surface of young individuals, especially in humid environments, is a characteristic feature of this species. S. pungens can usually be distinguished from other similar Suillus species by differences in distribution, odor and taste. (Full article...)

  • Image 14 Herbig–Haro (HH) objects are bright patches of nebulosity associated with newborn stars. They are formed when narrow jets of partially ionised gas ejected by stars collide with nearby clouds of gas and dust at several hundred kilometers per second. Herbig–Haro objects are commonly found in star-forming regions, and several are often seen around a single star, aligned with its rotational axis. Most of them lie within about one parsec (3.26 light-years) of the source, although some have been observed several parsecs away. HH objects are transient phenomena that last around a few tens of thousands of years. They can change visibly over timescales of a few years as they move rapidly away from their parent star into the gas clouds of interstellar space (the interstellar medium or ISM). Hubble Space Telescope observations have revealed the complex evolution of HH objects over the period of a few years, as parts of the nebula fade while others brighten as they collide with the clumpy material of the interstellar medium.

Ecology (from Ancient Greek οἶκος (oîkos)  'house' and -λογία (-logía)  'study of') is the natural science of the relationships among living organisms and their environment. Ecology considers organisms at the individual, population, community, ecosystem, and biosphere levels. Ecology overlaps with the closely related sciences of biogeography, evolutionary biology, genetics, ethology, and natural history. (Full article...)

Science things you can do
Many naturally occurring phenomena approximate a normal distribution.
Many naturally occurring phenomena approximate a normal distribution.
  • Integrate relatively new scientific knowledge and findings (major studies reported on by RS) into relevant articles
  • Expand 2025 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 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
