Figure 1. Fossilized nits of chewing lice, tightly affixed to feathers of an enantiornithine bird, entombed in mid-Cretaceous amber from northern Myanmar. (a) Isolated barbs and regularly arranged louse nits attached to two barbs of the same type. (b) Enlargement of six louse nits (indicated with black arrows). (c) Enlargement of five louse nits (indicated with white arrows). (d) and (e), Enlargement of louse nits. (f) Details of a nit, showing the placement, attachment, and details of the chorion. (g) Enlargement of two louse nits, showing the attachments to ramus. (h) Ecological reconstruction of Cretaceous chewing lice of an enantiornithine bird. (a–c) Under normal reflected light. (d–f) Under confocal laser scanning microscopy. (g) Under X-ray micro-computed tomography. Abbreviations: ch, chorion; eg, egg; ra, ramus.

This photograph of the Jovian moon Europa was taken in June 1997 at a range of 776,700 miles by NASA's Galileo spacecraft. Slightly smaller than Earth's moon, Europa has a very smooth surface and the solid ice crust has the appearance of a cracked eggshell. The interior has a global ocean with more water than found on Earth.

This caption explains the classification and grouping of hominin fossils: Homo juluensis (blue stars): Xujiayao, Xuchang, Xiahe, Penghu, Denisova, and Tam Ngu Hao 2. Homo longi (white triangles): Harbin, Dali, and Jinniushan. Homo floresiensis (pink diamond): Liang Bua. Homo luzonensis (green circle): Callao. Hualongdong (black inverted triangle), previously grouped with H. longi, is treated separately pending further investigation. Maba and Narmada (black squares), often considered a distinct population, may eventually be classified as H. neanderthalensis or given a new taxonomic name after further analysis. Details on type specimens and sites for the four species—H. floresiensis, H. luzonensis, H. longi, and H. juluensis—are provided in the accompanying box.
