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… Expand
Predictive implications of Gompertz’s law
Gompertz’s law tells us that for humans above the age of 35 the death rate increases exponentially with a doubling time of about 10 years. Here, we show that the same law continues to hold up to ageExpand
Effect of marital status on death rates. Part 1: High accuracy exploration of the Farr–Bertillon effect
The Farr–Bertillon law says that for all age-groups the death rate of married people is lower than the death rate of people who are not married (i.e. single, widowed or divorced). Although this lawExpand
Deciphering infant mortality
This paper is about infant mortality. In line with reliability theory, “infant” refers to the time interval following birth during which the mortality (or failure) rate decreases. This definitionExpand

The Nonlinear Dynamics of Survival and Social Facilitation in Termites
TLDR
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. Expand
Autocrine signals enable chondrocytes to survive in culture
TLDR
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. Expand
Control of lens epithelial cell survival
TLDR
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. Expand
Colony life history and lifetime reproductive success of red harvester ant colonies.
TLDR
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.
