A single tooth from the Popol Vuh Museum is attracting the attention of researchers studying ancient Maya remains..... The specimen is a lower molar featuring a small green stone set into the centre of its occlusal (chewing) surface. The material has been identified as jadeite. While stone inlays are well attested in Maya contexts, they are almost exclusively found in anterior (front) teeth; placement within a molar appears to be previously undocumented. The tooth comes from a collection of archaeological material gathered in Guatemala during the 20th century. It is not tied to a specific excavation, but its characteristics match known examples of Maya dental work. The crown shows a shaped cavity where the stone sits, held in place by a bonding substance. Imaging was carried out using cone beam computed tomography. The scans show changes inside the tooth that occur in living tissue. The pulp chamber displays heavy calcification, a response that develops over time. This indicates the procedure took place while the individual was alive. The internal structure is intact, with visible pulp horns and root canals. These features point to a young adult. There is no sign of advanced wear that would suggest old age. The position of the inlay is notable. Molar teeth are not visible during speech or display. Known Maya dental modifications usually focus on visible areas and are linked to appearance or identity. This example does not fit that pattern. One explanation is that the stone was placed for practical reasons. Tooth decay and infection were common in ancient populations, especially where diets relied heavily on maize. In other regions, there is evidence of drilling or filling teeth to manage pain or damage. Cases from Europe and Asia show early attempts to treat dental problems, including the use of plant fibres, bitumen or wax. In the Americas, similar work has been recorded, though examples are few. Most involve drilling rather than filling. The Maya had the technical skill to work teeth with precision. Decorative inlays show controlled shaping and placement without damaging the inner structure. This molar suggests that such skill may also have been applied in other contexts. There is no direct proof that the stone addressed a cavity or injury. The tooth does not preserve clear evidence of decay at the site of the inlay. Other motives cannot be excluded, though the location makes a display function unlikely. The find adds a rare example to the record of dental intervention in ancient Mesoamerica. It shows that work on teeth was not only limited to visible modification and aesthetic purpose. #archaeohistories

Opossums are among the most unfairly maligned animals in North America. Their nocturnal habits, hissing, and toothy displays often lead people to view them as pests or threats. In reality, these quiet marsupials provide some of the most valuable services in urban and suburban ecosystems. Contrary to popular belief, opossums very rarely carry or transmit rabies. Their lower body temperature makes it difficult for the virus to survive, making cases extremely uncommon. They are also highly effective pest controllers. A single opossum can consume thousands of ticks per season, helping reduce the spread of dangerous tick-borne illnesses like Lyme disease. Beyond ticks, they act as nature’s sanitation workers, scavenging on carrion, insects, fallen fruit, and organic waste. This cleanup work helps limit bacteria and disease while keeping ecosystems balanced. Their dramatic defensive displays, hissing, baring teeth, and even “playing dead” with a foul odor, are mostly bluffs designed to deter predators rather than signs of aggression. Far from being a nuisance, opossums are beneficial neighbors quietly doing the dirty work that keeps our environment cleaner and healthier. The next time you spot one, there’s no need to fear or harm it, just let it continue its important nighttime duties.
