Brain Research: Exploring the mind of a cyberterrorist ♦ How brain architecture leads to abstract thought ♦ Certain antidepressants linked to heightened risk of mania and bipolar disorder

Brain cancer self-organizes into streams, swirls, and spheres Brain cancer is not anarchy, say researchers but highly organized--self-organized. Researchers report that glioma cells build tumors by self-organizing into streams,10-20 cells wide, that obey a mathematically predicted pattern for autonomous agents flowing together. These streams drag along slower gliomas, may block entry of immune cells, and swirl around a central axis containing glioma stem cells that feed the tumor's growth.
Exploring the mind of a cyberterrorist A new study is delving into an aspect of cybersecurity rarely explored before now: the human component.
How brain architecture leads to abstract thought Using 20 years of functional magnetic resonance imaging (fMRI) data from tens of thousands of brain imaging experiments, computational neuroscientists have created a geometry-based method for massive data analysis to reach a new understanding of how thought arises from brain structure.
Certain antidepressants linked to heightened risk of mania and bipolar disorder Taking certain antidepressants for depression is linked to a heightened risk of subsequent mania and bipolar disorder, new research reveals. The strongest association seemed to be for serotonin reuptake inhibitors, or SSRIs for short, and the dual action antidepressant venlafaxine, the analysis indicated.
