Our species, Homo sapiens, dispersed from Africa into Eurasia multiple times in the Middle and Late Pleistocene. According to new research led by Shantou University scientists, the now arid zone of the Eastern Mediterranean was once green savannahs and grasslands that provided an ideal passage for these migrations. Abbas et al. support the growing consensus for a well-watered Jordan Rift Valley that funneled migrants into western Asia and northern...

This image from Webb’s NIRCam short-wavelength channel shows the Orion Nebula, its stars, and many other objects in unprecedented high definition in the near infrared. Many of the young stars are surrounded by dense disks of gas and dust which may be forming planets. In other cases, those disks are being destroyed by the intense ultraviolet radiation and strong winds from the most massive stars in the region. Many of these photoevaporating disks are visible if you zoom into the image. Image credit: NASA / ESA / CSA / M. McCaughrean / S. Pearson.

Artistic representation of the opportunistic burrowing behavior of the hypothetical ancestor of crown snakes, as predicted from reconstructed high-definition 3D whole-brain models (highlighted middle right) shown in dorsal (top) and lateral (bottom) views. In comparison, the reconstruction of the first natural endocast of a fossil snake (Dinilysia patagonica, top right) displays a divergent morphological configuration of the telencephalon (Tel) and provides no or limited information about the diencephalon (Dien), mesencephalon (Mes), cerebellum (Cb), and medulla oblongata (MO) regions. In contrast, the estimated endocast of Najash rionegrina (bottom right) shows similarities with the hypothetical ancestor of crown snakes in several distinguishable telencephalic regions, including cerebral hemisphere (CH), olfactory bulb (OB), and olfactory tract (OT). Reconstructions of the fossil skulls (purple color) are shown around the cranial endocasts. Image credit: Macrì et al., doi: 10.1126/sciadv.adi6888 / Neptalí Ramírez Marcial.
