The events of meiosis I in a living insect spermatocyte beginning at metaphase I with bivalents at the spindle equator followed by anaphase, segregation of half-bivalents diakinesis and commencement o...

Time series images showing the dynamics of kinetchore microtubules during meiosis I in primary spermatocytes of the crane-fly Nephrotoma suturalis that were experimentally flattened. Time-lapse polari...

The series of three vertical columns shows various aspects of mitotic anaphase in a live Barbulanympha (protist). The left column shows the birefringent spindle imaged by polarization microscopy; the...

Movie of anaphase A and B of meiosis I in primary spermatocytes of the crane-fly Nephrotoma suturalis. Time-lapse polarization microscopy using a Nikon Microphot SA, equipped for liquid crystal pola...

Time series of anaphase A and B of meiosis I in primary spermatocytes of the crane-fly Nephrotoma suturalis. Time-lapse polarization microscopy using a Nikon Microphot SA, equipped for liquid crysta...

This polarized photomicrograph shows the rows of suckers on the foreleg of a male Dytiscus marginalis, commonly known as the great diving beetle - the largest freshwater beetle in the UK. It has a lar...

Time series images showing the dynamics of kinetchore microtubules during meiosis I in primary spermatocytes of the crane-fly Nephrotoma suturalis that were experimentally flattened. Time-lapse polari...

The movie shows the effect of pressure on the spindle of the Chaetopteris egg. 100 Atm. of pressure induces depolymerization of spindle microtubules leading to the loss of birefringence in this polari...
