Science is a systematic discipline that builds and organises knowledge in the form of testable explanations about nature and society. It is driven by the scientific method: an empirical cycle that typically involves making observations, producing hypotheses, testing them with evidence, and drawing conclusions. Science encompasses this process and the body of knowledge it produces, which the scientific community continuously challenges, validates, and organises. (Full article...)
Cortinarius caperatus, commonly known as the wrinkled cort or gypsy mushroom, is a species of fungi of the genus Cortinarius. It was known as Rozites caperata for many years before genetic studies revealed that it belonged to the genus Cortinarius. The Latin specific name, caperatus, means wrinkled and refers to the distinctive texture of the cap. The ochre-coloured cap is up to 10cm (4in) across and has a fibrous surface. The clay-colored gills are attached to the stipe under the cap, and the stipe is whitish with a whitish ring. The flesh has a mild smell and flavor. It can resemble a number of other species, including the poisonous Inosperma erubescens in central Europe in summer. (Full article...)
Diagram of Fir Clump Stone Circle, based on Richard Reiss's 1965 measurements. The black marks represent stones recorded in the vicinity; the red lines demarcate the concentric rings of the putative circle.
The white-headed fruit dove (Ptilinopus eugeniae) is a species of bird in the pigeon family, Columbidae. It was described by the English ornithologist John Gould in 1856, and the specific nameeugeniae honours the French empress Eugénie de Montijo. Adults of the species have white heads, a purplish-red breast patch, a grey shoulder patch, olive-green upperparts, greenish underparts with a blue tinge, and a yellowish vent. Juveniles have green heads with the white restricted to the forehead and upper throat, a much smaller grey shoulder patch, and the red breast patch restricted to the centre of the breast.

Distribution of Transandinomys talamancae in southern Central America and northwestern South America
Transandinomys talamancae is a rodent in the familyCricetidae that occurs from Costa Rica to southwestern Ecuador and northern Venezuela. Its habitat consists of lowland forests up to 1,500m (5,000ft) above sea level. With a body mass of 38 to 74g (1.3 to 2.6oz), it is a medium-sized rice rat. The fur is soft and is reddish to brownish on the upperparts and white to buff on the underparts. The tail is dark brown above and lighter below and the ears and feet are long. The vibrissae (whiskers) are very long. In the skull, the rostrum (front part) is long and the braincase is low. The number of chromosomes varies from 34 to 54. (Full article...)

DNA nanotechnology involves forming artificial, designed nanostructures out of nucleic acids, such as this DNA tetrahedron. Each edge of the tetrahedron is a 20 base pair DNA double helix, and each vertex is a three-arm junction. The 4 DNA strands that form the 4 tetrahedral faces are color-coded.
The mandrill (Mandrillus sphinx) is a large Old World monkey native to west central Africa. It is one of the most colorful mammals in the world, with red and blue skin on its face and posterior. The species is sexually dimorphic, as males have a larger body, longer canine teeth and brighter coloring. Its closest living relative is the drill, with which it shares the genusMandrillus. Both species were traditionally thought to be baboons, but further evidence has shown that they are more closely related to white-eyelid mangabeys. (Full article...)
The Armero tragedy (Spanish: Tragedia de Armero[tɾaˈxeðjaðeaɾˈmeɾo]) occurred following the eruption of the Nevado del Ruizstratovolcano in Tolima, Colombia, on November 13, 1985. The volcano's eruption after 69 years of dormancy caught nearby towns unprepared, even though volcanological organizations had warned the government to evacuate the area after they had detected volcanic activity two months earlier.

Wōdejebato (formerly known as Sylvania) is a Cretaceousguyot or tablemount in the northern Marshall Islands, Pacific Ocean. Wōdejebato is probably a shield volcano and is connected through a submarine ridge to the smaller Pikinni Atoll 74 kilometres (46mi) southeast of the guyot; unlike Wōdejebato, Pikinni rises above sea level. The seamount rises for 4,420 metres (14,500ft) to 1,335 metres (4,380ft) depth and is formed by basaltic rocks. The name Wōdejebato refers to a sea god of Pikinni. (Full article...)
Writing is the act of creating a persistent, usually visual representation of language on a surface. As a structured system of communication, writing is also known as written language. Historically, written languages have emerged as a way to record corresponding spoken languages. A particular set of symbols, called a script, as well as the rules by which they encode a particular spoken language, is known as a writing system. In some rare cases, writing may be tactile rather than visual. (Full article...)
... that Na drugą planetę, published in 1895 as one of the earliest Polish science-fiction novels, was later criticized by communist-era censors for its perceived "adoration for America"?

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

Sci-Hub is a shadow library that provides free access to millions of research papers, regardless of copyright, by bypassing publishers' paywalls in various ways. Unlike Library Genesis, it does not provide access to books. Sci-Hub was founded in Kazakhstan by Alexandra Elbakyan in 2011, in response to the rising costs of research papers behind paywalls. The site is extensively used worldwide. In September 2019, the site's operator(s) said that it served approximately 400,000 requests per day. In addition to its intensive use, Sci-Hub stands out among other shadow libraries because of its easy use and reliability, as well as the enormous size of its collection. A 2018 study estimated that Sci-Hub provided access to almost all scholarly publications. On 15 July 2022, Sci-Hub reported that its collection comprised 88,343,822 files. In December 2020, the site paused uploads due to legal troubles. Since then, the site has archived a much lower fraction of new articles. (Full article...)

In biology, taxonomy (fromAncient Greekτάξις (taxis)'arrangement'and-νομία (-nomia)'method') is the scientific study of naming, defining (circumscribing) and classifying groups of biological organisms based on shared characteristics. Modern approaches prioritize common ancestry and evolutionary relationships. Organisms are grouped into taxa (singular: taxon), and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum (division is sometimes used in botany in place of phylum), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, having developed a ranked system known as Linnaean taxonomy for categorizing organisms.
