  1. Out of Africa: Black Power!

    Last Wednesday evening, I dined in a fashionable Nairobi restaurant with three recent graduates from the California Institute of Technology in Pasadena. Big brains, these three young men have chosen to pursue a distinctly unusual set of inventive possibilities. They are seeking to design, engineer and implement new sources of energy for people in the developing world living "off the grid." Step back a moment. For generations, the "grid" referred to the national electricity grid, the cornerstone of all power-generating activities in a given country. Throughout Africa and Asia, national grids are now straining to generate sufficient electricity to …

  2. Caltech engineers developing MEMS robots to position electrodes in the brain

    Spectrum reports that Caltech researchers are developing a MEMS robotic device to insert and position electrodes in the brain. The system could enhance the performance of neural prosthetics, which have proved hard to implant accurately. The researchers haven't built the device yet, but they've devised control algorithms to guide the miniature robots to make good neural connections. From the article: The Caltech team has designed a system that would make the procedure more predictable by attaching a tiny MEMS-based motor to each electrode on a multichannel electrode array and using an algorithm to direct the electrodes to individual neurons. [...] …
