2:17 AM | Is There Such a Thing as ‘Facebook Murder’?
Investigators recently set out to consider whether homicides involving social networking sites were unique and worthy of labels such as ‘Facebook Murder’, and to explore the ways in which perpetrators had used such sites in the homicides they had committed. The cases they identified were not collectively unique or unusual when compared with general trends […] The post Is There Such a Thing as ‘Facebook Murder’? appeared first on Wiley Asia Blog.

6:15 PM | From H. pylori to Spanish colonialism: the scales of cancer.
Yesterday was the first day of the 4th Integrated Mathematical Oncology Workshop here at Moffitt. This year, it is run jointly with the Center for Infection Research in Cancer and is thus focused on the interaction of infection disease and cancer. This is a topic that I have not focused much attention on — except […]

9:51 AM | How guessing the wrong answer helps you learn the right answer
Guessing, even wrongly, is thought toactivate webs of knowledge, which leadsto richer encoding of the correct answer. It's well known that taking tests helps us learn. The act of retrieving information from memory helps that information stick. This seems intuitive. More surprising is the recent discovery that guessing aids subsequent learning of the correct answer, even if your initial guess was wrong.Let's consider a simple example in the context of learning capital cities. Imagine you […]
