hypnosec writes:Scientists have created a paint that provides self-cleaning surfaces and can maintain them even after being wiped, scratched, or scuffed. The paint, composed of titanium dioxide (TiO2) nanoparticles, is delivered as a suspension in ethanol containing the chemical perfluorooctyltriethoxysilane (abstract). Once the coating is applied to a surface, the ethanol must evaporate for 180 seconds before it is ready for use. Depending on the surface, the coating can be sprayed, dipped, or painted.

Presto Vivace writes:O’Reilly Radar has an article about how ubiquitous tracking and collection of data will fundamentally change how we live. Quoting: “This timeline — beginning for newborns at Year Zero — will be so intrinsic to life that it will quickly be taken for granted. Those without a timeline will be at a huge disadvantage. Those with a good one will have the tricks of a modern mentalist: perfect recall, suggestions for how to curry favor, ease maintaining friendships and influencing strangers, unthinkably higher Dunbar numbers — now, every interaction has a history. This isn’t just about lifelogging health data, like your Fitbit or Jawbone. It isn’t about financial data, like Mint. It isn’t just your social graph or photo feed. It isn’t about commuting data like Waze or Maps. It’s about all of these, together, along with the tools and user interfaces and agents to make sense of it.”
mspohr writes“The Guardian describes robocops used in Kinshasa to direct traffic: “The solar-powered aluminum robots are huge, towering over the jammed streets of Kinshasa, as cars and motorcycles jostle for road room, their horns blasting. Each hand on the odd-looking machines — built to withstand the year-round hot climate — is fitted with green and red lights that regulate the flow of traffic in the sprawling city of nine million. The robots are also equipped with rotating chests and surveillance cameras that record the flow of traffic and send real-time images to the police station. These are second generation robots designed by a Congolese association of women engineers. Although the humanoids look more like giant toys than real policemen, motorists have given them a thumbs up. ‘There are certain drivers who don’t respect the traffic police. But with the robot it will be different. We should respect the robot,’ taxi driver Poro Zidane told AFP.”
