Back on YouTube channels again - you may have heard of the YouTube channel Veritasium. This one is a generally good science channel which has nearly 11 million subscribers.

Stuff published an article recently about the dangers of LED light bulbs, arguing that the blue light from LED bulbs disturbs our circadian rhythm and disrupts our sleep, with wide ranging knock-on effects to our health.

It seems that every new advance in technology is accompanied by people who are willing to warn the world of made up dangers.

People have warned others about the dangers of artificial sweeteners, GM foods and the LHC - all of which have a very low risk profile, and confer major benefits to society.
