It’s time to tuck into the April 2019 issue of Physics World magazine, which is now out in print and digital formats.

We have a great feature for you this month by Niladri Banerjee from Loughborough University about the new field of “superconducting spintronics”, which could lead to a new generation of “green” supercomputers (see more in the video above).

The cover feature, meanwhile, looks at a spectroscopy technique, developed by scientists at the UK’s’ National Physical Laboratory, which could help pharmaceutical firms to discover new drugs quickly and more cheaply.

Plus there’s all your other favourites, including Critical Point, Reviews, Careers, Lateral Thoughts and – with the UK’s impending departure from the EU – a couple of pieces about Brexit.

You can enjoy the April 2019 issue of Physics World magazine via our digital apps for iOS, Android and Web browsers (membership of the Institute of Physics required). Let us know what you think about the issue on Twitter, Facebook or by e-mailing us at pwld@iop.org.

For the record, here’s a run-down of what’s in the issue. For the record, here’s a run-down of what’s in the issue.

• Uncertainty principle – James McKenzie reflects on how the UK can improve the long-term prospects for physics-based firms after Brexit

• The new big science – Neutron-scattering facilities exemplify the changing face of big science, as Robert P Crease discovers on a visit to Oak Ridge

• The importance of archives – Valerie Higgins says that the contributions of support staff should not be forgotten when it comes to celebrating scientific breakthroughs

• Dealing with Brexit – Matin Durrani says Brexit is a chance for the uK to reset and reinvigorate its support for physics

• CERN beyond the LHC – CERN director-general Fabiola Gianotti talks to Physics World about how the lab is planning the next big experiment in particle physics beyond the Large Hadron Collider

• High-spec mass spec – Big pharmaceutical firms have to make big-risk investments when inventing new drugs. But one physicist’s new spectroscopy tool could radically change that, as Jon Cartwright reports

• A cool spin on supercomputers – Niladri Banerjee explains how the emerging field of “superconducting spintronics” could lead to a new generation of green supercomputers that use far less energy than previous devices

• Bringing the cosmos down to Earth – In Our Universe: an Astronomer’s Guide, Jo Dunkley condenses the history of the cosmos into an accessible page-turner. James Dacey catches up with the Princeton University astronomer to find out why she believes cutting-edge astronomy should be accessible to all readers

• As real as it gets – Philip Ball reviews Einstein’s Unfinished Revolution: the Search For What Lies Beyond the Quantum by Lee Smolin

• Seeing past the ordinary –Margaret Harris catches up with founder Ralf Kaiser and director David Mahon of Lynkeos Technology, a company that develops muon tomography systems for applications in the nuclear industry and beyond

• Once a physicist – Meet Mike DeArmond, a sales engineer for MANTIS-SIGMA, who works with researchers to define and provide solutions for experimental programmes focusing on materials, condensed matter and surface science

• A tale of two theories – Oliver Linton muses on the striking parallel between the current debate on the multiple interpretations of quantum mechanics, and the arguments that raged over the astronomical theories of the solar system, nearly 400 years ago.
