Weakly electric gymnotiform and mormyrid fish generate and detect weak electric fields to image their worlds and communicate. These multi-purpose electric signals are generated by electrocytes, the specialized electric organ (EO) cells that produce the electric organ discharge (EOD). Just over 50 years ago the first experimental analyses of electrocyte physiology demonstrated that the EOD is pr...

Our understanding of the nature of interstellar grains has evolved considerably over the past half century with the present author and Fred Hoyle being intimately involved at several key stages of progress. The currently fashionable graphite-silicate-organic grain model has all its essential aspects unequivocally traceable to original peer-reviewed publications by the author and/or Fred Hoyle. ...

quate to express the impact that these advances have Even in their wildest dreams, it seems unlikely that back had on science as we now know it. The Royal Society in 1953 Watson and Crick could have imagined how far meeting in London showcased the current status of DNA DNA science would develop in 50 years. We’ve come research. David Sherratt and Steve West organized a all the way from their in...
