Neural and cognitive characteristics of extraordinary altruists.
Altruistic behavior improves the welfare of another individual while reducing the altruist's welfare. Humans' tendency to engage in altruistic behaviors is unevenly distributed across the population, and individual variation in altruistic tendencies may be genetically mediated. Although neural endophenotypes of heightened or extreme antisocial behavior tendencies have been identified in, for ex...
متن کاملAltruists in the PicoRadio Sensor Network
Self-configuring wireless sensor networks are a fascinating emerging technology: the vision is to spread out hundreds or thousands of small, cheap, battery-driven, and self-configuring nodes bearing a wireless modem to accomplish a given task jointly. An important concern is the network lifetime: as nodes run out of power, the connectivity decreases and the network can finally be partitioned an...
متن کاملStrategic Behavior of Moralists and Altruists
Does altruism and morality lead to socially better outcomes in strategic interactions than selfishness? We shed some light on this complex and non-trivial issue by examining a few canonical strategic interactions played by egoists, altruists and moralists. By altruists, we mean people who do not only care about their own material payoffs but also about those to others, and, by a moralist, we me...
متن کاملChemoattractants attract HIV researchers
I n this issue of the Journal of ExperimentaI Medicine, Loetscher et al. show that receptors for ~-chemokines are upregulated when T lymphocytes are activated by interleukin-2 (1). This paper will be of considerable interest not just to those who have worked for some years to identify conditions whereby chemokines could attract T ceils, but also to HIV researchers and conceivably to retrovirolo...

Axons have their own translational machinery that allows them to respond to stimuli rapidly. Store...
