Laserocarpum, a new genus of Apiaceae endemic to Greece
Acta Societatis Botanicorum Poloniae, 2019 Laserpitium pseudomeum is an endemic umbellifer of Greece occurring in the mountains of Sterea Ellas and northern Peloponnese. Molecular data indicate that it is not related to its putative congeners, but instead constitutes an isolated lineage.

Bacterial symbionts support larval sap feeding and adult folivory in (semi-)aquatic reed beetles
Nature Communications, 2020 Symbiotic microbes in insects can enable their hosts to access untapped nutritional resources. Here, the authors show that symbiotic bacteria in reed beetles can provide essential amino acids to sap-feeding larvae and help leaf-feeding adults to degrade ...

The Astrophysical JournalWithin the Milky Way (MW), younger stellar populations exhibit steeper (more negative) metallicity radial gradients; the origin of this trend remains debated. The FIRE-2 cosmological simulations of MW-mass galaxies show the same trend as the MW, which in

Searching for lost nucleotides of the pre-RNA World with a self-refining model of early Earth
Nature Communications, 2018 The nucleotides of RNA appear to be products of evolution. Experimental studies are showing that plausible proto-nucleotides can be formed in simulated early Earth environments.

, 1965 How did life come to be on the surface of the earth? Darwin himself recognized that his basic idea of evolution by variation and natural selection must be a continuous process extending backward in time through that period in which the first living things arose and into the period of 'Chemical Evolution' which preceded it.
