Unexpectedly high ultrafine aerosol concentrations above East Antarctic sea ice [PDF]

Atmospheric Chemistry and Physics, 2016
Better characterisation of aerosol processes in pristine, natural environments, such as Antarctica, have recently been shown to lead to the largest reduction in uncertainties in our understanding of radiative forcing.

Divalent metal transporter-related protein restricts animals to marine habitats

Communications Biology, 2021
Mieko Sassa et al. report a novel divalent metal transporter protein (DMTRP) in the crown-of-thorns starfish genome and determine that all organisms with a DMTRP gene are located in marine habitats.

Comparative genomics highlight the importance of lineage-specific gene families in evolutionary divergence of the coral genus, Montipora

BMC Ecology and Evolution, 2022
Background Scleractinian corals of the genus Montipora (Anthozoa, Cnidaria) possess some unusual biological traits, such as vertical transmission of algal symbionts; however, the genetic bases for those traits remain unknown.

Atmospheric Mass Loss During Planet Formation: The Importance of Planetesimal Impacts [PDF]

, 2014
We quantify the atmospheric mass loss during planet formation by examining the contributions to atmospheric loss from both giant impacts and planetesimal accretion. Giant impacts cause global motion of the ground.
