Survival of the Sawfly Athalia rosae Upon Infection by an Entomopathogenic Fungus and in Relation to Clerodanoid Uptake

open access: yesFrontiers in Physiology, 2021
Larvae of the turnip sawfly Athalia rosae are a pest of Brassicacae plants, as their feeding can cause defoliation of various crops of economic importance.

CHEMICAL EVOLUTION IN VeLLOs [PDF]

open access: yesJournal 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.

Surface force analysis of glycine adsorption on different crystal surfaces of titanium dioxide (TiO2)

open access: yesNano Convergence, 2017
Surface force analysis with atomic force microscope (AFM) in which a single amino acid residue was mounted on the tip apex of AFM probe was carried out for the first time at the molecular level on titanium dioxide (TiO2) as a representative mineral ...

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

open access: yesScientific 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.

Linked cycles of oxidative decarboxylation of glyoxylate as protometabolic analogs of the citric acid cycle

open access: yesNature Communications, 2018
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

open access: yesThe 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.

Stellar Chemical Evolution [PDF]

open access: yesSymposium - International Astronomical Union, 1997
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 ...
