This month we also have an Insight on Ultracold atom technologies go.nature.com/31LXKpP The Insight is briefly introduced in this editorial by our editors Richard Brierley and Yun Li go.nature.com/3GswKdO

Sweet fifteen | Nature Physics turns 15 this month, so we thought we'd celebrate 🎉

go.nature.com/34k8IjI Feature | Over the last 15 years, the content of Nature Physics has covered an enormous breadth of subjects at the forefront of physics. The journal’s past and present editors recount their favourite papers go.nature.com/2GsD77a

Our September editorial is our a little early (rest of the issue isn't due until Thursday!) This month, we take time to check in on the progress at ITER and nuclear fusion research more broadly | The way ahead for fusion go.nature.com/2ESdQCQ Inside ITER | Q&A with @iterorg’s Director-General, Bernard Bigot, and Tim Luce, head of its Science & Operations Department go.nature.com/3lFoAoP

This month, a Focus issue highlights recent developments in fundamental research on superconductivity

Editorial | go.nature.com/2DcQfM8 Review by Benjamin Sacépé, Mikhail Feigel’man & Teunis M. Klapwijk | Quantum breakdown of superconductivity in low-dimensional materials go.nature.com/3gzElu9

This month, we Focus on the European Strategy for Particle Physics go.nature.com/39KAery This is the decision-making process underpinning the long-term future of particle physics in Europe, and it is due to be updated in 2020 | Read more in our editorial: Strategy for the future go.nature.com/2whwbFi

Check out our Focus issue on cavity quantum electrodynamics (cQED) go.nature.com/cQED What is cQED? Roughly, a platform to study and manipulate light-matter interactions at the quantum level | Read more in our Editorial: The ABC of cQED go.nature.com/ABCcQED

Quantum phases on demand | The need to control the properties of quantum materials has led to a burst of interest in their properties out of equilibrium. Understanding this regime represents an opportunity for theorists and experimentalists alike go.nature.com/2R1bVyh On the January cover: Light-induced anomalous Hall effect in graphene go.nature.com/37ZXotY

We asked the physics community their opinion on data and code sharing, and their implementation. We've published the feedback we've received in our August issue, but you can also find them collected here go.nature.com/2YgQ38g A problem halved is a problem shared -- the editorial that kicked it off go.nature.com/2G6mmxv

Happy World Metrology Day! Today, 7 fundamental constants of nature are redefined as exact numerical values, in turn redefining base units such as the metre and the kilogram. Find out more about this reformation in Bill Philips' #MeasureForMeasure column | go.nature.com/endofartefacts Metrology is a fascinating, and hugely important, discipline - one that underpins our fundamental understanding of science as much as the practical foundations of all international commerce throughout human history. It is worth celebrating in full: go.nature.com/2HqOs5P

Today is #SIRedefinition day. Read up on why this has come about in the Commentary by Joachim Fischer & Joachim Ullrich rdcu.be/bbusO Dedicated readers will also known that for the past few years we've been running a dedicated column on metrology, Measure for Measure: nature.com/articles/nphys…

This month we have a Focus issue exploring quantum thermalization across different length scales go.nature.com/2xZ1Ed1 Editorial | New horizons on quantum thermalization go.nature.com/2DVT9Vu

Insight on the physics of living systems | Our latest Insight showcases research across the many length scales relevant to living systems — from molecules and cells to tissues, organisms and populations. go.nature.com/physicsoflivin… Editorial by @avklopper go.nature.com/2KQdhYn
