The insecticide DDT is an omnipresent environmental contaminant and an ongoing toxicological concern. The recent discovery that methylenetetrahydrofolate (MTHF) models are capable of reducing a range of halocarbons to hydrocarbons under biomimetic co

Assessment of the compressibility of marine mammal airways at depth is crucial to understanding vital physiologic processes such as gas exchange during diving. Very few studies have directly assessed changes in cetacean and pinniped trachea-bronchial

The reduction of halocarbons by NADH models and NADH under ambient conditions is reported as a new type of reactivity pointing towards a hitherto unknown disruptive pathway for NADH/NADPH-dependent processes. The reaction was studied with the omnipre

Methylenetetrahydrofolate models (green substructure) reduce organohalides to the respective hydrocarbons under biomimetic conditions and mimic the activity of dehalohydrogenases.

Replacement of fish species by their congeners along gradients of stream size is common in warm-water streams, but the causative environmental factors driving this turnover are not fully understood. We used laboratory experiments to test for differen

Experimental values for the strength of the sulfur–sulfur bond scatter over a wide range and are frequently in disagreement with each other. For S8, reliable experimental data seem to lack entirely. To check experimental data and establish the stre
