    Interesting. The article doesn’t actually say that fluoridation in water supplies is dangerous but that some researchers are questioning. Generally code for lack of scientific evidence. It also finds that early studies may have had a flawed basis (pretty much all early studies have been found wanting by later scientists) but doesn’t refute the results.The study mentioned in the article talks about high levels of fluoridation which I assume is in lab tests however these levels are not the case in water supplies.

    The correct way forward is more actual science based studies.


















  • As I recall it, the system used cameras or maybe radar to detect the cars some distance away so it had time to optimise the lights. The Google system seems to be based on historical data which probably the quickest way to improve using the current technology. My observation is that most traffic lights are set and forget so there are probably huge improvements possible.

    As google data is based on mobile phones, they probably do have data on pedestrians as well as cars which could be promising.

    To really fix things there will need to be new technology to allow realtime adjustments which introduces the opportunity to detect bikes and pedestrians.
