For thousands of years indigenous peoples have invented ingenious, often strikingly beautiful ways to harvest marine resources that, in combination with their belief systems, prevented overharvesting. But today, commercial fisheries and skyrocketing human populations are driving the future of resources from the sea toward a dangerous tipping point. Inspired by marine biologist Daniel Pauly, a group of indigenous knowledge holders and community members, scientists and artists led by Anne Salomon, a Simon Fraser University professor, formed the Pacific Sea Garden Collective and created an elegantly simple interactive map to share traditional ways that people interacted with the sea, hoping to inspire a more sustainable future.

Social networks are used more often in poor neighbourhoods than in affluent neighbourhoods, while the latter tend to consume more information from traditional online media. This is one of the conclusions of a scientific study undertaken by researchers at the Universidad Carlos III de Madrid (UC3M), the IMDEA Networks Institute, and Orange Innovation which analyses the relationship between internet usage and variables such as education, income, or inequality in a specific area.

Most modern cultures practice some form of dental modification, for health, therapeutic or aesthetic purposes: whether it’s filling a cavity, removing wisdom teeth, adding veneers or braces or whitening teeth.

Sweat baths have a long history of use in Mesoamerica. Commonly used by midwives in postpartum and perinatal care in contemporary Maya communities, these structures are viewed as grandmother figures, a pattern that can also be traced to earlier periods of history. At the site of Xultun, Guatemala, a Classic Maya sweat bath with an unusual collection of artifacts led archaeologists from the Smithsonian Tropical Research Institute (STRI), the Archaeology Program at Boston University and other collaborating institutions to gather new evidence of these beliefs and an early example of the related ritual practices.

More than 35,000 bone and shell fragments from a Maya settlement in Ceibal, Guatemala tell the tale of animal use through the ups and downs of a great civilization according to a new report in the journal PLOS One by Ashley Sharpe, staff archaeologist at the Smithsonian Tropical Research Institute, with colleagues from the University of Arizona, the University of Ibaraki, Japan and Guatemala’s Institute of Anthropology and History and Universidad de San Carlos.
