This month’s issue of How It Works is super hot thanks to our in-depth coverage of the brand new Amazon Kindle Fire, a revolutionary new eReader/tablet hybrid that is opening up a new chapter in digital content consumption. Adding to the heat further is an explosive feature on supernovas, where we explain how these world-ending events generate more energy than a billion suns and can stretch distances greater than our entire solar system. In addition, we continue to push towards critical temperature with an high-energy feature on laser power fusion – a potential replacement for fossil fuels – and get red hot in a feature dedicated to unlocking the secrets of supercar construction. All that and much, much more in issue 28 of How It Works, available from WHSmiths, supermarkets and all good newsagents.
