Chemical Evolution of a Bacterium’s Genome [PDF]

Angewandte Chemie International Edition, 2011
We set out to develop a generic technology for evolving the chemical constitution of microbial populations by using the simplest possible algorithm. Extant living cells polymerize a restricted set of nucleic acid precursors, namely, four nucleoside triphosphates (UTP, CTP, ATP, GTP) and four deoxynucleoside triphosphates (dTTP, dCTP, dATP, dGTP ...

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

Nano 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 ...

The effect of polyploidy and hybridization on the evolution of floral colour in Nicotiana (Solanaceae). [PDF]

, 2015
Speciation in angiosperms can be accompanied by changes in floral colour that may influence pollinator preference and reproductive isolation. This study investigates whether changes in floral colour can accompany polyploid and homoploid hybridization ...

Chemical Reaction Networks Explain Gas Evolution Mechanisms in Mg-Ion Batteries

, 2023
Out-of-equilibrium electrochemical reaction mechanisms are notoriously difficult to characterize. However, such reactions are critical for a range of technological applications.

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

Nature 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 ...

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.
