Johan Bollen and his colleagues at Indiana University in Bloomington have created an anxiety rating based on an analysis of hundreds of millions of tweets by people in the US. Their paper has not yet been published, but Bollen says they too found that increases in anxiety on their scale correlated with lower than expected stock prices. “We’re astounded,” he says. “We didn’t think it would be a predictive relationship.” - New Scientist
By embedding a nano-sized transistor inside a cell-like membrane, scientists link humans and machines more intimately than ever.
Scientists embedded a biologically powered transistor inside a cell membrane.
The device is the most intimate binding of man and machine yet achieved.
The research could lead to new man-machine interfaces.
