Scientists from across the globe met in Switzerland last month for the launch of the Human Brain Project. However, building a computer to simulate the human brain is no easy task: in each cubic millimeter of brain tissue there are around 100,000 neurons, and each one makes contact with around 10,000 other neurons. Markus Diesmann, from Germany’s Jülich Research Centre, provides insight into the complexities surrounding this epic undertaking. He speaks about his work on simulating a circuit of the whole-brain network and discusses how specialized software can help represent the neurons and synapses of the full circuit. 


With the advent of high-frequency trading, traders can compete in the market, taking advantage of brief price differences to clean up on profit. Last year, iSGTW published a story about how supercomputers were helping to analyze market data to uncover the unfair trading practices. This article is a follow-up to the 2012 article and discusses two common practices high-frequency traders use and the policy change implemented in October 2013 to level the playing field.
