STIMulating Ca2+ influx

736 L ike rowdy bar patrons, centro-somes must be booted from the cell during oogenesis. To achieve this, a cell cycle regulator moonlights as a bouncer for centrosomes, as shown by Kim and Roy on page 751. In most organisms, centrosomes are removed from the developing egg to prevent the fertilized zygote from inheriting redundant sets from both the egg and the sperm. But too many of these micr...

Polar cap influx

This study uses digital ionosonde data from a cusp latitude station (Cambridge Bay, 77 CGM lat.) to study the convection into the polar cap. Days when the IMF magnetic field was relatively steady were used. On many days it was possible to distinguish an interval near noon MLT when the ionosonde data had a different character from that at earlier and later times. Based on our data, and other pub...

Influx into Fly Photoreceptors

Ion-selective calcium microelectrodes were inserted into the compound eyes of the wild-type sheep blowfly Lucilia or into the retina of the no steady state (ms) mutant of Lucilia. These electrodes monitored light-induced changes in the extracellular concentration of calcium (A[Ca2+]o) together with the extracellularly recorded receptor potential. Prolonged dim lights induced a steady reduction ...
