Apatosaurus knee joint disease When researchers excavated the Apatosaurus femur specimen from the Morrison Formation in Wyoming (fossil number: UWGM 7213), they noticed that the lateral condyle and lateral epicondyle had inward erosion lesions. After preliminary determination, they believed that the lesion was the source of the disease. The inflammatory reaction caused by the erosion … Read more

Nature highlight May 11, 2023 Nature 6177960 The Bell inequality has helped shed light on the structure of correlations allowed by quantum mechanics and what this theory of physics says about the world. Experimental verification of the Bell inequality is also of practical importance, as it allows confirmation of the existence of true quantum correlations … Read more
Few creatures have pushed anatomy to its limits as much as sauropods. These giant dinosaurs moved on column-like legs that supported their massive bodies, wagging whip-like tails to ward off predators and using their long necks to devour foliage. This entire group of dinosaurs is commonly known as the long-necked dinosaurs, but the Mamenchisaurus, which … Read more
The study of archaic DNA brings new insights. Currently, scientists are focused on two personalities working at the German Max Planck Institute, namely Cosimo Post and Svante Pääb (Pääbo received the Nobel Prize last year for his work in the field of paleogenetics – late order.)focused on how the distribution of populations and their genetic … Read more
It has been known for a long time that the days at the end of the Mesozoic era were a little shorter than today’s, so that the solar year also had more days (various studies in the past reported a range of 370.3 to 375 days).[1] A more recent scientific work from 2020 probably definitively … Read more
