“The secret of the blue fog” might sound like a Tintin book, but it’s all about a strange form of liquid crystal that’s the cover story in the April 2017 issue of Physics World magazine, which is now live in the Physics World app for mobile and desktop.
First observed in the late 1800s, only recently have we finally uncovered the structure of these materials, which turn blue when cooled. As Oliver Henrich and Davide Marenduzzo explain, blue liquid crystals could be used for new kinds of display devices.
Elsewhere in the issue, mathematical physicist Jason Lotay explains his work in seven extra dimensions, while science writer Benjamin Skuse examines the challenge for respected physicists with theories outside the mainstream.
Don’t miss either our latest look at Donald Trump’s scientific shenanigans, including an interview with Rush Holt – the physicist-turned-politician who’s now head of the American Association for the Advancement of Science.
