Abstract The phenomenonof apoptosisobserved in cell cultures consists in the fact that unless cellspermanently receive a “Stay alive” signal from their neighb ors, they are bound to die. A natural ques-tion is whether manifestations of this apoptosis paradigm can also be observed in other organizationsof living organisms. In this paper we report results from a two-year long campaign of experiments onthree species of ants and one species of (tephritid) fruit fli es. In these experiments… 



The Nonlinear Dynamics of Survival and Social Facilitation in Termites

It was found that survival was significantly lower for isolated individuals and higher for individuals in bigger group sizes, suggesting that social interactions play an important role in the mechanisms leading to longer survival.

Autocrine signals enable chondrocytes to survive in culture

The hypothesis that most mammalian cells require signals from other cells to avoid programmed cell death (PCD) is supported, although the signals can sometimes be provided by cells of the same type, at least in tissues that contain only one cell type.

Control of lens epithelial cell survival

Lens epithelial cells survived for weeks in both explant cultures and high-density dissociated cell cultures in the absence of other cells or added serum or protein, suggesting that they do not require signals from other cell types to survive.

Colony life history and lifetime reproductive success of red harvester ant colonies.

The results provide the first estimate of a life table for a population of ant colonies and the first estimates of the female component of colony lifetime reproductive success, and suggest that commonly used measures of reproductive output may not be correlated with realized reproductive success.

La «Survivone» substance qui induit la suvie des abeilles isolées

Honeybees isolated with some dead bees live longer than strictly isolated controls and all extracts are toxic for isolated bees, with the exception of ethylic ether extracts.

High-Tech Business Survivorship: An Analysis By Organization Type

Previous studies have shown that organizational and environmental factors such as start-up size, number of establishments, start-up year, geographic location, and industry are all significant

Cell suicide for beginners

An overview of recent progress in understanding the nature of the suicide process and how it is controlled is considered.

Les variations annuelles dans l'effet de groupe chez l'abeille et l'origine de la mort précoce des isolées

Observations of young bees showed that, during winter particularly, the mortality of isolated bees occurs in two stages, the junction between which was about the seventh day of age.

Resultate kalorimetrischer Studien

Bekanntlich besteht zwischen Mischungswärmen und spezifischen Wärmen ein thermodynamischer Zusammenhang derart, dass die Differenz der Wärmekapazitäten der ungemischten und gemischten Substanzen

It has been found that vertical surfaces which have been coated with a dispersion of polytetrafluorethylene constitute a barrier over which ants and certain other insects are unable to climb.
