The Chemical Evolution of the Galaxy [PDF]
Symposium - International Astronomical Union, 1985 Over the last few years, our picture of the chemical evolution of the Galaxy has changed substantially. These changes are of interest because chemical evolution provides a common point of contact for most astrophysical processes of importance to galaxy evolution.

A small molecule screen identifies novel inhibitors of mechanosensory nematocyst discharge in Hydra
Scientific Reports, 2021 Cnidarians are characterized by the possession of stinging organelles, called nematocysts, which they use for prey capture and defense. Nematocyst discharge is controlled by a mechanosensory apparatus with analogies to vertebrate hair cells.

Evolution of the Mass–Metallicity Relation from Redshift z ≈ 8 to the Local Universe
The Astrophysical Journal, 2023 A tight positive correlation between the stellar mass and the gas-phase metallicity of galaxies has been observed at low redshifts. The redshift evolution of this correlation can strongly constrain theories of galaxy evolution.

CHEMICAL EVOLUTION IN VeLLOs [PDF]
Journal of The Korean Astronomical Society, 2007 A new type of object called "Very Low Luminosity Objects (VeLLOs)" has been discovered by the Spitzer Space Telescope. VeLLOs might be substellar objects forming by accretion. However, some VeLLOs are associated with strong outflows, indicating the previous existence of massive accretion.
