Wylie et al. investigated the metallicity, age, and orbital anatomy of the inner Milky Way, specifically focusing on the outer bar region. This image shows a metallicity map of the inner Milky Way, based on orbital data calculated by Wylie et al. The red star marks the position of the Sun, while the white dashed lines mark different sight lines. The red contours show specific density levels to highlight important features: a bar in the middle with a ring-like structure around it.

Odor preference rankings were collected from nine culturally and geographically diverse populations. These included the three hunter-gatherer groups, Seri from a coastal desert and Maniq and Semaq Beri from tropical rainforest, one shoreline forager, Mah Meri, from a tropical coast; one swidden-horticulturalist, Semelai, from tropical rainforest; one farmer-foraging community, Chachi, from tropical rainforest; one subsistence agriculturalist community, Imbabura Quichua, from temperate highlands; and two urban dwellers from industrial and postindustrial communities of bustling urban settings, Mexican and Thai. The data from these nine communities were then related to available data from a large dataset on odor preference collected from urban dwellers from New York City, the United States.
