Addition of ribonuclease to an actively growing culture of Escherichia coli B which has been exposed to ionizing radiation (Cobalt 60 γ-rays) results in a substantial increase in survivors. This paper discusses conditions under which this phenomenon

A variety of protein and RNA inhibitors were tested on habituation learning in the protozoan Spirostomum. Inhibition of protein synthesis up to values of 95% had no effect upon habituation, and RNA inhibition up to 89% by 5-fluorouracil had only slig

Paramecia sucked up into a small capillary tube eventually took less and less time to escape from it. This change in escape time over trials could be eliminated if the tubes were cleaned in a prescribed manner before use and the organisms were adapte

RNA changes accompanying learning have been found in rats, mice, goldfish and planaria1–8. We wanted to determine whether changes in the rate of RNA synthesis occurred during habituation in the protozoan Spirostomum ambiguum, for this would extend

An increase in protein and RNA synthesis is found during habituation in the protozoan Spirostomum . Habituation also occurs when all macronuclei and some of the cytoplasm is removed. RNA synthesis also increases but protein does not. Protein synthesi

THE protozoan Spirostomum habituates to a series of mechanical shocks so that it no longer contracts to the stimulus; after several minutes the organisms have returned to their pre-stimulus level of sensitivity1. We propose a preliminary theory to ex

VARIOUS higher plants make rapid movements in response to stimuli1–3, among them Mimosa which rapidly closes its leaves when touched. We wish to report a series of experiments demonstrating such fast closure in response to light alone. Usually, lig
