You’ll be delighted to know that the February 2018 issue of Physics World is now out in print and digital format.

In our cover feature this month, science writer Jennifer Ouellette discovers how tiny midges can shed light on collective behaviour in physics. You can also discover from Helen Gleeson how physicists are seeking to create liquid-crystal contact lenses – and learn from Stephen Ornes more about the technological challenges of going to Mars.

Don’t miss either our interview with the physicist who heads Japan’s leading funding agency and find out from astrophysicist Elizabeth Tasker about her experiences as an overseas scientist in the country.

And our veteran North America correspondent Peter Gwynne assesses the impact that Donald Trump has had on US science, one year into his presidency.

Remember that if you’re a member of the Institute of Physics, you can read the whole of Physics World magazine every month via our digital apps for iOS, Android and Web browsers.
