Giant Octopuses May Have Ruled the Oceans 100 Million Years Ago Fossilized jaws of ancient octopuses, discovered in Japan and Vancouver Island, have revealed that these creatures may have been apex predators in the oceans 100 million years ago. A study led by researchers at Hokkaido University, published in Science, challenges previous assumptions about the role of invertebrates in marine ecosystems, suggesting that early octopuses occupied the top of the food web alongside large marine vertebrates. The findings, based on advanced imaging and artificial intelligence analysis, indicate that these ancient octopuses were not merely elusive, soft-bodied animals but powerful hunters capable of crushing hard prey with immense force. The study focused on fossilized jaws from the Late Cretaceous period, spanning 100 to 72 million years ago. These fossils, preserved in calm seafloor sediments, retained fine wear patterns that provided insights into the feeding behavior of these extinct creatures. The researchers used high-resolution grinding tomography and a zero-shot learning AI model to digitally mine the fossils, revealing intricate details of their structure. The jaws belonged to a group of extinct finned octopuses known as Cirrata, which were likely active predators. The analysis of jaw size, shape, and wear patterns suggested that these animals could have grown to nearly 20 meters in length, surpassing the size of contemporary marine reptiles. Professor Yasuhiro Iba of Hokkaido University emphasized the significance of the findings, noting that the fossilized jaws showed extensive damage, including chipping, scratching, cracking, and polishing. These signs of wear indicated a strong biting force, with up to 10% of the jaw tip relative to the total length worn away in well-developed specimens.#science #japan #vancouver_island #hokkaido_university #cirrata
This is an X-ray of a #woman who ate raw pork for 10 years A woman who regularly ate raw pork for ten years ended up with a severe #parasitic #infection . The larvae entered her intestines and gradually spread throughout her body into muscles, soft tissues, and even around the joints. There, they turned into dense, capsule-like formations that went unnoticed for years while slowly destroying the surrounding tissues. On images like X-rays and CT scans, infections like this look terrifying: dozens of calcified “dots,” resembling scattered foreign objects. These are hardened parasite capsules that once migrated through the body. Over time, a person begins to experience muscle pain, swelling, weakness, headaches, and constant fatigue. If left untreated for years, the consequences can become nearly irreversible. This story is a reminder that even a small habit repeated day after day can quietly undermine your #health . Properly cooking meat isn’t a formality, it’s real protection against parasites that are invisible to the naked eye but capable of changing a life forever. #science #MedicalEducation

The ‘Universe 25’ experiment is one of the most disturbing studies in the history of science, carried out by American scientist John Calhoun between 1958 & 1962. Calhoun designed an ideal environment for rats, called “Mouse Paradise”, with abundant food, water and space, in order to study the social dynamics of a growing population. Initially, the colony prospered, but after 317 days, population growth began to stagnate. Upon reaching 600 mice, serious social problems arose: hierarchies were established, the strongest individuals began to attack others, and aggressive and maladaptive behaviors emerged, such as violence between females and a lack of reproductive interest in males. As passive, non-reproductive (beautiful mice) males dominated, the birth rate plummeted, juvenile mortality reached 100%, and the colony collapsed into cannibalism and homosexuality. The experiment was repeated 25 times, each time with similar results, and has been used to model the study of social collapse and urban sociology. #Universe25Experiment #science #ScienceExperiment
