Rob Fredrick at American Scientist interviewed me for a podcast he made on one of the talks at the European Conference for Science Journalists in Copenhagen. I told him about my 2009 Nature story “Fake Facebook pages spin web of deceit” and we discussed the talk.

Copenhagen’s public electric bikes are kind of a pain to get started: they are heavy and their coaster brake prevents riders from kicking the pedal around to a convenient starting place. The business side of the operation has also had a rough start, marked by delivery delays, bankruptcy, and restructuring. Once you do manage to push the bikes to a start, however, their 250-W electric motors kick in and they are a breeze to power around Copenhagen’s well-marked and protected bike lanes.
It may not have been electricity, but something has also boosted the Copenhagen bike-sharing program: Usage grew from just 169,000 rides in 2015 to 933,000 last year and the program, called Bycyklen, is on track for similar usage this year. That might be just enough to keep Bycyklen from falling over. Continue reading Danish Electric Bike-Sharing Dodges Failure
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. Continue reading How Bots Win Friends and Influence People
Copenhagen, the city that popularized bike sharing in the 1990s, is replacing its coin-operated clunkers with electric motor–assisted bicycles with their own touch-screen instrument panels. The bikes, which the city beta-tested this past September and October, house motors that can provide up to 450 watts of power from a battery pack that’s rechargeable at dozens of docking stations around the city. But all that power may be too much of a good thing.
Beta testers last month “got very good at keeping [their] momentum to where the engine does most of the work,” reports Niklas Marschall, CEO of Cykel DK, the program’s operator. That was the first lesson Cykel DK learned: Riders will go to great lengths to avoid exerting themselves. Continue reading Copenhagen Pioneers Smart Electric-Bike Sharing
