Dendrocnide moroides, also known as the stinging brush, mulberry-leaved stinger, gympie, gympie stinger,[1] stinger, the suicide plant, or moonlighter, is a plant in the nettle family Urticaceae common to rainforest areas in the north-east of Australia.[2][3][4] Gympie-gympie, its common and original name, comes from the language of the indigenous Gubbi Gubbi people of South Queensland. It is also found in Indonesia. It has stinging hairs which cover the whole plant and delivers a potent neurotoxin when touched, by the small bulb that is found on the tip of the stinging hairs being broken off and penetrating the skin to inject the toxin.[5] It is the most toxic of the Australian species of stinging trees.[2][4] The fruit is edible to humans if the stinging hairs that cover it are removed.[6] D. moroides usually grows as a single-stemmed plant reaching 1–3 m (3 ft 3 in–9 ft 10 in) in height. It has large, heart-shaped leaves about 12–22 cm (5–9 in) long and 11–18 cm (4–7 in) wide, with finely toothed margins.
The New Mexico whiptail (Aspidoscelis neomexicanus) is a female-only species of lizard found in the southwestern United States in New Mexico and Arizona, and in northern Mexico in Chihuahua. It is the official state reptile of New Mexico.

Retrocausality, or backwards causation, is a concept of cause and effect in which an effect precedes its cause in time and so a later event affects an earlier one.

nonas trying to learn calculus or just interested i recommend this video https://youtu.be/WUvTyaaNkzM and the whole series, it's really good explaining what is calculus i honestly believe they should teach it in this way.

Reptiles, as most commonly defined, are the animals in the class Reptilia /rɛpˈtɪliə/, a paraphyletic grouping comprising all amniotes except synapsids (mammals and their extinct relatives) and Aves (birds).[1] The class comprises turtles, crocodilians, snakes, amphisbaenians, lizards, tuatara, and their extinct relatives. In the traditional Linnaean classification system, birds are considered a separate class to reptiles. However, crocodilians are more closely related to birds than they are to other living reptiles, and so modern cladistic classification systems include birds within Reptilia, redefining the term as a clade. Other cladistic definitions abandon the term reptile altogether in favor of the clade Sauropsida, which refers to all animals more closely related to modern reptiles than to mammals. The study of the traditional reptile orders, historically combined with that of modern amphibians, is called herpetology. The earliest known proto-reptiles originated around 312 million years ago during the Carboniferous period, having evolved from advanced reptiliomorph tetrapods which became increasingly adapted to life on dry land. The earliest known eureptile ("true reptile") was Hylonomus, a small and superficially lizard-like animal. Genetic and fossil data argues that the two largest lineages of reptiles, Archosauromorpha (crocodilians, birds and kin) and Lepidosauromorpha (lizards and kin), diverged near the end of the Permian period.[2] In addition to the living reptiles, there are many diverse groups that are now extinct, in some cases due to mass extinction events. In particular, the Cretaceous–Paleogene extinction event wiped out the pterosaurs, plesiosaurs, ornithischians, and sauropods, alongside many species of theropods, crocodyliforms, and squamates (e.g., mosasaurs).

Quantum physics is very interesting, why small particles act so different and what does everything mean. https://www.youtube.com/watch?v=UjaAxUO6-Uw this video explains well the Schrodinger cat though experiment and superposition
quantum entanglement is also such an interesting phenomenon, where particles after interacting remain "entangled" and work the same even if they are light years apart https://www.youtube.com/watch?v=fkAAbXPEAtU
and last why such an important thing like the laws of nature are ruled by probability? quantum physics has mathematics said shit like “The idea of an objective real world whose smallest parts exist objectively in the same sense as stones or trees exist, independently of whether or not we observe them ... is impossible,”, science so removed and hard to look for the facts that we have things like "interpretation of quantum physics" to make sense out of it, it's been almost 100 years since the foundation of quantum physics was layout by great minds like Einstein and Bohr, Feynman and Schrodinger. i personally like to believe in the many worlds interpretation even when it has problems because well it makes sense to me hopefully one day we as a human species can discovered such mysteries https://www.youtube.com/watch?v=kTXTPe3wahc parallel worlds explanation
>>206107 >>206110 >>206116 thanks for bumping (?)
>>206119 kek i wanted to post it on dst but i realized that this is the most appropriate place for my quantum physics ramblings

>>206132 >https://www.independent.co.uk/news/science/archaeology/news/brain-magnets-decrease-faith-god-religion-immigrants-a6695291.html i just started to check this stuff and it's so fascinating!, thank you so much for posting this. how i never thought about it before obviously electromagnetism affects neurons since the way they communicate is between electric impulses/ions, i'm going to post interesting stuff i find during my research

Magnetic-field-induced DNA strand breaks in brain cells of the rat. Henry Lai and Narendra P Singh Author information Copyright and License information Disclaimer See letter "Electromagnetic Fields and Free Radicals" on page A726a. This article has been cited by other articles in PMC. Abstract In previous research, we found that rats acutely (2 hr) exposed to a 60-Hz sinusoidal magnetic field at intensities of 0.1-0.5 millitesla (mT) showed increases in DNA single- and double-strand breaks in their brain cells. Further research showed that these effects could be blocked by pretreating the rats with the free radical scavengers melatonin and N-tert-butyl-alpha-phenylnitrone, suggesting the involvement of free radicals. In the present study, effects of magnetic field exposure on brain cell DNA in the rat were further investigated. Exposure to a 60-Hz magnetic field at 0.01 mT for 24 hr caused a significant increase in DNA single- and double-strand breaks. Prolonging the exposure to 48 hr caused a larger increase. This indicates that the effect is cumulative. In addition, treatment with Trolox (a vitamin E analog) or 7-nitroindazole (a nitric oxide synthase inhibitor) blocked magnetic-field-induced DNA strand breaks. These data further support a role of free radicals on the effects of magnetic fields. Treatment with the iron chelator deferiprone also blocked the effects of magnetic fields on brain cell DNA, suggesting the involvement of iron. Acute magnetic field exposure increased apoptosis and necrosis of brain cells in the rat. We hypothesize that exposure to a 60-Hz magnetic field initiates an iron-mediated process (e.g., the Fenton reaction) that increases free radical formation in brain cells, leading to DNA strand breaks and cell death. This hypothesis could have an important implication for the possible health effects associated with exposure to extremely low-frequency magnetic fields in the public and occupational environments. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1241963/ This one is cited in 37 articles, i'm going to try to read them and what i find interesting, but basically this article says that prolonged exposure to low-level magnetic fields,can damage brain cell DNA. https://www.washington.edu/news/2004/02/18/exposure-to-low-level-magnetic-fields-causes-dna-damage-in-rat-brain-cells-researchers-find/ it's the same research but explained in terms a little more simple
>>206246 this was interesting especially about how the treatment could make it worse or better and how iron blocked some effects. fascinating stuff good find anon

does anyone here believes in ancient aliens?
>>703816 not really but i love to watch docus/read about it i just think some ancient civilizations were really advanced and because of our linear view of time and history it seems hard to believe that they achieved it all by themselves. i’m more interested in anunakis or in general the idea of some human cousins that went a different evolution route and then disappeared. it is a really recurrent theme in a lot of ancient traditions
>>704508 i believe that aliens were gods
is there any anonymous ib for science heads or engineers?
>>706142 i believe that too. more so i believe that we become those aliens in the future with better technology and create ourselves. more like a loop of time. and hence a god
