BuzzFeed collects Reddit anecdotes and expert notes to highlight 21 enduring puzzles about the human body—ranging from colic and labor triggers to how anesthesia or sleep truly works and why autoimmune diseases or brain injuries defy easy prediction—illustrating that much of biology remains not fully understood.
Life’s Little Mysteries examines how much of the body a person can lose and still survive, explaining the limits of bodily tolerances for tissue and blood loss, and it features an interactive bones quiz that tests readers on skeletal facts (e.g., the adult skeleton has about 206 bones; largest bone is the femur; smallest is the stapes) and other anatomy trivia.
A Guardian briefing questions sensational claims of large amounts of microplastics in the human body, highlighting measurement challenges and potential false positives in early studies. While microplastics are pervasive environmentally, the exact levels in people remain uncertain and methods are still being refined; the health risks are not yet clear, but the broader case for cutting plastic pollution remains strong.
A wave of high-profile claims that microplastics permeate human tissues—from brain to blood—faces fresh scrutiny, with researchers citing contamination, blanks and inadequate validation as likely causes; experts urge robust, multi-method verification as the field matures and warn against policy decisions based on fragile findings.
The article showcases a collection of 57 striking and sometimes unsettling medical images and stories that highlight the complexity, resilience, and mysteries of the human body, from rare conditions and remarkable recoveries to advances in medical technology and ongoing scientific questions.
Scientists at Stanford have developed a new imaging technique called computational scattered light imaging (ComSLI) that allows detailed visualization of microscopic fiber networks in human tissues, which could lead to better understanding of diseases like Alzheimer's and other neurological disorders. The method is accessible, requiring only a simple setup with a light source and microscope camera, and can analyze existing tissue samples with high resolution, opening new avenues for research and diagnosis.
Dutch researchers conducted experiments where couples had sex inside MRI machines to study bodily responses, discovering that the penis bends to fit the vaginal canal and that women's bladders fill rapidly during sex, though the reasons for these phenomena remain unclear.
The human body has approximately seven or eight topologically distinct holes, including the mouth, anus, nostrils, tear ducts, and possibly the vagina and fallopian tubes, depending on how connections are counted, with the count influenced by the topological perspective that considers how openings connect internally.
Modern research suggests humans have between 22 and 33 senses, including traditional senses like sight and hearing, as well as others like proprioception, interoception, and the sense of ownership, all working together to create a unified perception of the world.
Scientists from the University of Pennsylvania and Michigan have developed a sub-millimeter robot capable of sensing, thinking, and acting, which could eventually be used inside the human body for medical purposes, although it is still in the experimental stage.
Gold is more widespread than commonly thought, found in the human body, oceans, space, and even plants, revealing its surprising presence in various natural and extraterrestrial environments.
Gold can be found in unexpected places such as the human body, seawater, meteorites, volcanoes, and even within plants, highlighting its diverse natural presence beyond traditional mining sources.
The article showcases 48 fascinating photos of the human body, highlighting its incredible ability to heal, adapt, and the various medical conditions and procedures, from wrinkles and extra teeth to complex surgeries and injuries.
Scientists have confirmed that living organisms, including humans, emit faint biophotons due to oxidative metabolic processes in mitochondria, and this emission ceases after death. The phenomenon, observable in both animals and plants, is purely biochemical and could have applications in health and ecological monitoring.
A study has found that the human body emits a faint visible light, called biophotons, which ceases at death, indicating a link to metabolic activity; this discovery could have future applications in medical and agricultural diagnostics.
