Rethinking the roots of altruism For decades, researchers working to understand how altruistic behavior evolved have relied on a concept known as inclusive fitness, which holds that organisms receive an evolutionary benefit—and are able to pass on their genes—through cooperative behavior. Now Harvard scientists say the theory is mathematically flawed and unnecessarily complicates the story of altruism's evolution. In a new study, Martin Nowak, a professor of mathematics and of biology, E.O. Wilson, the Pellegrino University Professor Emeritus, and Benjamin Allen, a research associate in mathematical biology and an assistant professor at Emmanuel College, find that not only is inclusive fitness impossible to calculate in most cases, but also that it often leads to incorrect conclusions. The research is described in a paper published in the Proceedings of the National Academy of Sciences. "Our main goal is to develop a rigorous mathematical theory of evolution," Nowak said.
Trust Me This is what trust looks like inside your head. In the late 1930s, a teenaged boy named Ferdinand Waldo Demara, Jr. ran away from his family home in Lawrence, Mass., to embark upon an extraordinary career of deception that earned his the nickname "The Great Imposter." Over the next couple of decades, Demara managed to pass himself off as a college psychology professor, a Catholic priest, a high school teacher, and even as a Canadian Royal Navy surgeon who was trusted to perform delicate operations. How did Demara, who had no qualifications for any of these jobs, manage to convince other people to believe in him and trust him with lofty responsibilities? Judging from photographs, Demara's biggest asset—besides his high intelligence and brazenness—may have been his appearance. And as it turns out, evaluating facial features generally is a fairly effective way to make a quick judgment about whether or not a person is worthy of trust.

Topographical disorientation Topographical Disorientation, also known as Topographical agnosia and Topographagnosia, is the inability to orient oneself in one's surroundings as a result of focal brain damage.[1] This disability may result from the inability to make use of selective spatial information (e.g., environmental landmarks) or to orient by means of specific cognitive strategies such as the ability to form a mental representation of the environment, also known as a cognitive map. It may be part of a syndrome known as visuospatial dysgnosia. Classification[edit] Topographical Disorientation is the inability to orient in the surrounding as a result of focal brain damage.[1] Topographical Disorientation has been studied for decades using case studies of patients who have selectively lost their ability to find their way within large-scale, locomotor environments. Several dozen case reports of topographical disorientation have been presented over the last century. Developmental Topographical Disorientation[edit]
