After months of critical deliberation, the Survey Science Group (SSG), along with its community working groups, have focused in on the following survey definition for the VLA Sky Survey (VLASS), culminating in a cohesive science program that has been identified to simultaneously provide the largest scientific impact, generate substantial involvement from all astronomical communities, and leave ...

The relationship between autocrine interferon (IFN) production and the expression of class I Major Histocompatibility Complex (MHC) membrane glycoproteins in vitro was investigated in a panel of murine transformed cells of nonhaemopoietic origin. The panel included 11 cell lines of H-2Kb haplotype derived from fibrosarcomas, carcinomas and melanoma, and from transformed fibroblasts. IFN activit...

Amalgam has, ever since its introduction 150 years ago, been the subject of recurrent controversies because of its mercury content. Amalgam is an unstable alloy and continuously gives off mercury (Hg) in the form of gas, ions and abraded particles (Stock, 1939 a, Radics et al., 1970, Mocke, 1971, Till and Wagner, 1973, Svare et al., 1981). Amalgam contains an especially cor-rodible gamma-2-phas...

Refuge theory postulates that repeated oscillation of dry and moist climatic periods during the Pleistocene caused an alternating fragmentation and coalescence of areas of lowland tropical rainforest vegetation, leading to genetic differentiation and speciation in isolated populations of rainforest organisms and hence accounting for much of the high diversity now apparent in these habitats. The...

Ideally, any experienced investigator with the right tools should be able to reproduce a finding published in a peer-reviewed biomedical science journal. In fact, the reproducibility of a large percentage of published findings has been questioned. Undoubtedly, there are many reasons for this, but one reason may be that investigators fool themselves due to a poor understanding of statistical con...

The format of communicating scientific, technical, and medical (STM) information through professional journals has changed relatively little since the publication in 1665 of the Philosophical Transactions of the Royal Society, the world’s first journal devoted exclusively to science. Although advances in information technology have dramatically altered the search and discovery of scientific inf...
