Viv — another step in the cognition race. Wolfram Alpha was first out the gate, but Watson, Viv, and others are hot on heels of being able to parse complex requests, then seek and use information to fulfil them.
Universal Mobile Electrochemical Detector Designed for Use in Resource-limited Applications (PNAS) — $35 handheld sensor with mobile phone connection. The electrochemical methods that we demonstrate enable quantitative, broadly applicable, and inexpensive sensing with flexibility based on a wide variety of important electroanalytical techniques (chronoamperometry, cyclic voltammetry, differential pulse voltammetry, square wave voltammetry, and potentiometry), each with different uses. Four applications demonstrate the analytical performance of the device: these involve the detection of (i) glucose in the blood for personal health, (ii) trace heavy metals (lead, cadmium, and zinc) in water for in-field environmental monitoring, (iii) sodium in urine for clinical analysis, and (iv) a malarial antigen (Plasmodium falciparum histidine-rich protein 2) for clinical research.
