CHEMICAL EVOLUTION IN VeLLOs [PDF]
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.

A small molecule screen identifies novel inhibitors of mechanosensory nematocyst discharge in Hydra
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.

The citric acid cycle (TCA) is a fundamental metabolic pathway to release stored energy in living organisms. Here, the authors report two linked cycles of reactions that each oxidize glyoxylate into CO2 and generate intermediates shared with the modern ...

Evolution of the Mass–Metallicity Relation from Redshift z ≈ 8 to the Local Universe
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.

Stellar Chemical Evolution [PDF]
One of the major achievements of astrophysics has been the demonstration that most of the chemical elements have been synthesized in stars: nucleosynthesis calculations of homogeneous and inhomogeneous big bang cosmologies show that, in comparison with the most metal-poor stars currently known, essentially no elements heavier than B existed at the era ...
