Fecal incontinence, arising from a myriad of pathogenic mechanisms, has attracted considerable global attention. Despite its significance, the replication of the defecatory system for studying fecal incontinence mechanisms remains limited largely due to social stigma and taboos. Inspired by the rectum's functionalities, we have developed a soft robotic system, encompassing a power supply, pressure sensing, data acquisition systems, a flushing mechanism, a stage, and a rectal module. The innovative soft rectal module includes actuators inspired by sphincter muscles, both soft and rigid covers, and soft rectum mold. The rectal mold, fabricated from materials that closely mimic human rectal tissue, is produced using the mold replication fabrication method. Both the soft and rigid components of the mold are realized through the application of 3D-printing technology. The sphincter muscles-inspired actuators featuring double-layer pouch structures are modeled and optimized based on multilayer perceptron methods aiming to obtain high contractions ratios (100 %), high generated pressure (9.8 kPa), and small recovery time (3 s). Upon assembly, this defecation robot is capable of smoothly expelling liquid faeces, performing controlled solid fecal cutting, and defecating extremely solid long faeces, thus closely replicating the human rectum and anal canal's functions. This defecation robot has the potential to assist humans in understanding the complex defecation system and contribute to the development of well-being devices related to defecation.

These'poopocalypses' were a disgusting problem that even the manufacturers admitted back in 2016 was'seen a lot' and needed a solution. The Roomba j7 can also avoid getting tangled in cables, automatically clean only when everyone has left the house and learn from the feedback you give it. And each robot is covered by POOP -- the'Pet Owners' Official Promise -- with iRobot offering to replace any Roomba j7 that doesn't avoid solid pet waste. The WiFi-enabled Roomba j7, which comes with a'clean base' automatic dirt disposal system is retailing in the UK, US, Canada and Europe now from £899.99. Each Roomba j7 model is covered by POOP -- the'Pet Owners' Official Promise -- with iRobot offering to replace any Roomba j7 that doesn't avoid solid pet waste.

The intestines and their bacteria are sometimes called our'second brain', but studying these bacteria in their natural environment is difficult. Now researchers from the University of Copenhagen have developed a method that uses artificial intelligence to map intestinal bacteria using faeces. The researchers thus hope to gain more knowledge of the role played by these bacteria in various diseases. Both past and present-day scientists have suspected the intestines of playing a role in various diseases. Present-day studies focus on the intestinal flora's role in physical diseases such as diabetes and overweight, while others seek to establish a connection between the intestinal flora and e.g.

Dog faeces can still be troublesome thousands of years after being dumped. Archaeologists can end up in deep doodoo if they mistake it for human faeces. But now an artificial intelligence system has been developed to discern the two. Ancient faeces, or coprolites, can be a valuable source of information about the identity, diet and health of people who lived thousands of years ago. But dog faeces, which are a similar size and shape, are also common at many archaeological sites.
