The movie shows two sequences that begin with an unfertilized Arbacia (sea urchin) egg in which the contents have been stratified using the centrifuge polarizing microscope (CPM) developed by S. Inoue...

This is one of 4 grouped time lapse movies (CIL 11958-11962) revealing the responses of a meiotic oocyte spindle to various forms of micromanipulation by a glass microneedle. The needle is inserted, ...

Desmid Micrasterias, a chlorophyceae alga of extraordinary beauty, beginning to divide. Micrasterias have bilateral symmetry, with two mirror image semi-cells joined by a narrow isthmus containing th...

The movie shows several sequences showing changes in birefringence in oocytes of the marine annelid Chaetopteris that had formed meiotic spindles before exposure to centrifugal force in the Centrifuge...

Time lapse movie showing several sequences of mitosis in pollen mother cells of the Easter Lily recorded in 1951 on 16 mm film with an early polarizing microscope developed by Shinya Inoue. The work w...

This is one of 4 grouped time lapse movies (CIL 11958-11962) revealing the responses of a meiotic oocyte spindle to various forms of micromanipulation by a glass microneedle. The needle is inserted, ...

The time lapse movie shows the rocking motion of the spindle that appears to play a role in the unequal cleavage divisions in a fertilized Spisula solidissima (Clam) egg. Eventually, this leads to t...

This sequence taken with the polarizing microscope in 1967 shows the reversible enhancement of spindle volume and birefringence by heavy water in arrested metaphase oocyte of Pectinaria gouldi (ice cr...

Dividing eggs of the medusa Clypeaster japonicus showing birefringent spindles and fertilization envelopes. The arrow indicates the direction of the compensator slow axis. As the direction of compensa...

This is a live image of the bdelloid rotifer Philodina roseola under 20x magnification. Bdelloid rotifers are microscopic freshwater invertebrates best known for their capacity to undergo frequent cyc...
