Experimental evidence that clay inhibits bacterial decomposers: Implications for preservation of organic fossils

Evidence of Double Dissociation in Auditory Agnosia: Implications for Rehabilition

Evidence for evolution from fossils

That is, carbon-14 decays into nitrogen-14, an electron, and an electron antineutrino. Laboratory experiments demonstrate that it is not possible to predict when any given nucleus will decay. In addition, the probability of decay in the next time interval dt is completely independent of how long the nucleus has lasted up to that point, be it an attosecond or a billion years. What this means is ...

Experimental Evidence for Abiotic Sulfurization of Marine Dissolved Organic Matter

Dissolved organic sulfur (DOS) is the largest pool of organic sulfur in the oceans, and as such it is an important component of the global sulfur cycle. DOS in the ocean is resistant against microbial degradation and turns over on a millennium time scale. However, sources and mechanisms behind its stability are largely unknown. Here, we hypothesize that in sulfate-reducing sediments sulfur is a...

Organic Synthesis using Clay Catalysts

One of the major current challenges before chemists is to develop synthetic methods that are less polluting, i.e., to design clean or ‘green’ chemical transformations. The chemical manufacturing processes should be such that they do not cause permanent damage to the environment or disturb the ecological balance. Ways to minimize the consumption of energy and raw materials used in synthesis must...

Characterization of a novel antibacterial agent that inhibits bacterial translation.

Bacterial protein synthesis is the target for several classes of established antibiotics. This report describes the characterization of a novel translation inhibitor produced by the soil bacterium Flexibacter. The dipeptide antibiotic TAN1057 A/B was synthesized and designated GS7128. As reported previously, TAN1057 inhibits protein synthesis in both Escherichia coli and Staphylococcus aureus, ...
