a, The direction-dependent optical properties of Ta2PdS6. Theoretical simulations of the polarized optical absorption of Ta2PdS6. Ta2PdS6 exhibits significant polarized absorption properties under optical excitation at 1.56 μm (corresponding to a photon energy of about 0.8 eV). b, The polarization-dependent transmission at various incidence powers. The anisotropic transmittance of Ta2PdS6 was experimentally measured under laser … Read more

Southern Keeled Octopus hatchling, a study species for the aging guide. Credit: Erica Durante Octopuses have been around for hundreds of millions of years, but did you know that most only live for a few years, dying soon after mating or laying eggs? Until now that hasn’t been a problem, but octopus catches have doubled … Read more

A graph from the BBB study showing the distribution of angiosperm fossils over time. Credit: Daniele Silvestro et al Flowers may look delicate—but flowering plants, what scientists call angiosperms, are one of the most successful evolutionary organisms on the planet. Including more than 350,000 known species, they dominate the ecological system, shape food webs and … Read more
