Shipboard system that uses limestone and seawater could cut CO₂ emissions by half
Scientists at USC and Caltech, in collaboration with startup company Calcarea, have developed a promising shipboard system that could remove up to half of carbon dioxide emitted from shipping vessels by converting it into an ocean-safe solution.

XRISM Spectroscopy of the Stellar-Mass Black Hole 4U 1630-472 in Outburst
We report on XRISM/Resolve spectroscopy of the recurrent transient and well-known black hole candidate 4U 1630$-$472 during its 2024 outburst. The source was captured at the end of a disk-dominated high/soft state, at an Eddington fraction of $λ_\mathrm{Edd} \sim 0.05~(10 M_{\odot}/M_\mathrm{BH})$. A variable absorption spectrum with unprecedented complexity is revealed with the Resolve calorimeter. This marks one of the lowest Eddington fractions at which highly ionized absorption has been de…
