Harvard relaxes COI rules for clinical researchers.

Harvard Medical School has relaxed its conflicts of interest (COI) rules for faculty members who conduct clinical research, more than doubling the amount they can receive from the companies whose products they are investigating. Previous rules allowed faculty members to receive nomore than $10 000 from each company whose technology they were studying. But under new rules issued on 12 May, facul...

Short COI markers for freshwater macroinvertebrate metabarcoding

Species diversity of metazoan bulk samples can be rapidly assessed using Cytochrome c oxidase I (COI) metabarcoding. However, in cases where only degraded DNA is available, e.g. from poorly conserved museum specimens, eDNA filtered from water or gut content analyses, universal primer sets that amplify only a short COI fragment are advantageous. Using PrimerMiner, we optimised two universal prim...

Measles vaccine deaths: the IAP-COI stand.

COI oxidation on a single Pd atom supported on magnesia.

The oxidation of CO on single Pd atoms anchored to MgO(100) surface oxygen vacancies is studied with temperature-programmed-reaction mass spectrometry and infrared spectroscopy. In one-heating-cycle experiments, CO(2), formed from O(2) and CO preadsorbed at 90 K, is detected at 260 and 500 K. Ab-initio simulations suggest two reaction routes, with Pd(CO)(2)O(2) and PdCO(3)CO found as precursors...

COI Stories: Explanation and Evidence in the History of Science

This paper takes as its point of departure two striking incongruities between scientiac practice and trends in modern history and philosophy of science. (1) Many modern historians of science are so preoccupied with local scientiac practices that they fail to recognize important non-local elements. (2) Many modern philosophers of science make a sharp distinction between explanation and evidence,...
