Every now and then sociologist Phil Howard writes messages to social media accounts accusing them of being bots. It’s like a Turing test of the state of online political propaganda. “Once in a while a human will come out and say, ‘I’m not a bot,’ and then we have a conversation,” he said at the European Conference for Science Journalists in Copenhagen on June 29.

Soil in the Forecast
For several days in late September 2015, heavy rains soaked the earth surrounding the district of El Cambray II in Guatemala. On the first night of the following month, steep slopes, long held in place by thick, tropical tree roots, suddenly gave way, burying hundreds of homes in mud up to 15 meters deep. At least 280 people died.
Officials had warned residents for years that the area was at risk, but a mixture of poverty and mistrust leads some of the poorest people in Central America and beyond to build and live on marginal land. Still, residents of El Cambray II might have been willing to temporarily evacuate, if they had received a credible and precise warning.

Ashley Madison was using more than 70,000 bots to lure in users, Gizmodo found in a 2015 investigation.
The message-sending profiles were one iteration of a growing army of bots that populate our online social networks, affecting everything from our wallets to our politics. Now they are attracting academic study and government research dollars. Continue reading Taxonomy Goes Digital: Getting a Handle on Social Bots
Big Data vs. Bad Air
In mid-October 2016, officials from China’s Ministry of Environmental Protection counted five illegal trash-burning sites and hundreds of thousands of vehicles exceeding emission standards in Beijing alone. For the first time since last winter’s pollution high season, city officials issued a yellow air-quality alert, which required shutting down power plants and reining in Beijing’s frenetic factories and road traffic. If this winter is anything like past winters, the city will have to pull out the yellow card again—and may even have to reach for its red card.
