The practical usefulness of biomarkers is limited by the complexity of linking their responses to life-history traits of the organisms (e.g., survival, growth, reproduction) over time. Here we present a first attempt to simultaneously model biomarker responses and survival over time with a toxicokinetic-toxicodynamic approach. Even though more work is ...

Organophosphonates are ancient molecules that contain the chemically stable C-P bond, which is considered a relic of the reducing atmosphere on primitive earth. Synthetic phosphonates now have a wide range of applications in the agricultural, chemical and pharmaceutical industries. However, the existence of C-P compounds as contemporary biogenic molecules was ...

High-throughput genomic technologies are revolutionizing human genetics. So far the focus has been on the 1.5% of the genome, which is coding, in spite of the fact that the great majority of genomic variants fall outside the coding regions. Recent efforts to annotate the non-coding sequence show that over 80% ...
