The European Strategy for Particle Physics is the decision-making process underpinning the long-term future of particle physics in Europe. This Focus issue outlines the main proposals under consideration for the 2020 update to the strategy.
We present this Collection of research, review and comment from Nature Research to celebrate the award of the 2019 Nobel Prize in Physics to James Peebles “for theoretical discoveries in physical cosmology” and to Michel Mayor and Didier Queloz “for the discovery of an exoplanet orbiting a solar-type star”. Together, these discoveries have changed the way we view the Universe, and our place within it.

Perovskite materials have become very promising candidates for a new generation of potentially printable and efficient optoelectronic devices. Photovoltaic devices based on hybrid perovskites now achieve more than 20% photoconversion efficiency, and applications in solid-state lighting, photodetection and lasing are soaring. Their optoelectronic and photophysical properties are under intense scrutiny.
This web-collection brings together a selection of multi-disciplinary research and comments published in the Nature journals that explores the basic properties of halide-based perovskite materials and their potential for application in optoelectronics, from solar cells to lasers. It serves to illustrate the road to easily processable and efficient devices by presenting both historical milestones and the crucial landmark studies published in the last 12 months in the Nature journals.
The increased sharing of data and code is often presented as an important part of the future of research, but the details of how best to implement this can be difficult to determine. In February, we published and editorial where we discussed our view on these issues and asked the physics community to share their opinions with us. Here, we collect the feedback that we published along with a second editorial that summarises our response and our plans to encourage more extensive sharing of data in the future.
