Turbulent mixing resolves decades-old puzzle of excess interstellar carbon
A new simulation code shows gas never reaches chemical equilibrium in turbulent PDRs, matching observed C I and CO columns.

Hawking evaporation needs write
A conditional no-go shows why most memory schemes fail, and hysteresis opens new tests for black holes.
· “The Forgetful Black Hole: Memory Burden and Hysteresis in Hawking Evaporation”
Water megamasers could map black holes out to 300 Mpc
Tenfold sensitivity plus VLBI would let sub-mm masers deliver black-hole masses and geometric distances alone.
