Paleoanthropologists have found 1.95-million-year-old cut-marked bones that appear to have been made by early hominins using stone tools at the site of Grăunceanu in Romania. The discovery sheds new light on the timing and extent of hominin dispersal across Eurasia. This is an artist’s reconstruction of female Homo from Dmanisi, Georgia.

Planck’s law ignores but does not prohibit black-body radiation (BBR) from being circularly polarized. BBR from nanostructured filaments with twisted geometry from nanocarbon or metal has strong ellipticity from 500 to 3000 nanometers. The submicrometer-scale chirality of these filaments satisfies the dimensionality requirements imposed by fluctuation-dissipation theorem and requires symmetry breaking in absorptivity and emissivity according to Kirchhoff’s law. The resulting BBR shows emission anisotropy and brightness exceeding those of conventional chiral photon emitters by factors of 10 to 100. Image credit: Lu et al., doi: 10.1126/science.adq4068.
