So far, approaches to mapping the density of cities have often been oversimplified, causing them to overlook many key aspects of everyday urban life. Through his research, Dr Elek Pafka at the University of Melbourne introduces two new metrics for measuring urban density, which better capture its complex, multi-scale variations. His research offers deeper insights into how people experience and interact with cities, and could lead to new strategies to make our cities more productive, sustainable, and better places to live.

In principle, travelling wave reactors offer a safe, highly efficient approach to generating nuclear power. However, development has been held back by a variety of challenges linked to the need for extensively high burn-up in the reactor core, meaning very high rates of generated energy which can damage the reactor. Inspired by the principles of Tai-Chi, a team led by Di Yun from Xi’an Jiaotong University has shown that with the right approach, a high temperature operation, usually deemed as a threat, can be transformed into useful advantages, bringing the practical rollout of travelling wave reactors one step closer to reality.

The full extent of the labour and resources which go into creating a modern house is hidden deeply within the buildings we call home. Professor Mark Jarzombek of MIT and Professor Vikramaditya Prakash of the University of Washington are co-founders of the Office of Uncertainty Research, a research collaboration that is dedicated to rethinking architecture in a modern context. Through their research, Jarzombek and Prakash investigate these hidden stories by exploring the history of a recently built modern house in Seattle. Their findings reveal that the presumed transparency of modern architecture conceals deep ethical and environmental challenges, inspiring a call for a critical reassessment of how our current construction practices should be understood and approached.

Studying single molecules provides researchers with unique insights into biological mechanisms and processes and allows them to visualise microscopic structural and functional differences. However, results can be unpredictable, and investigations are labour-intensive and expensive, often requiring extensive training and highly specialised laboratory equipment. Dr Rishabh Shetty and colleagues at Arizona State University, the California Institute of Technology, and the Massachusetts Institute of Technology, USA, have recently developed a simplified single-molecule assessment technique to overcome these limitations with a view to increasing accessibility and precision in molecular-level research.

Today, the success of businesses and technologies relies on their ability to make quick decisions to address complex problems. To make matters more complex, these problems often involve a vast amount of data. Dr Marius Nagy at Prince Mohammad Bin Fahd University, together with Dr Naya Nagy, Imam Abdulrahman Bin Faisal University, investigate the ability of quantum computers to act as an ‘oracle’, and provide quality decisions even after just one invocation. Dr. Nagy and Nagy showed that quantum oracles give richer decision proposals and outperform classical computing oracle versions.

AI appears all-powerful when playing sophisticated games such as Chess and Go against human opponents. Moreover, recent developments in AI have allowed it to summarize bodies of complex text, generate images and even video. These developments come with warnings that AI could replace many jobs, undermine democratic elections or even pose a threat to the existence of humanity. However, AI is largely based on observing and learning patterns; so, what happens when there are no patterns? Professor Steven Brams of New York University and colleagues have analyzed the potential of beating AI when playing a deceptively simple game called Catch-Up, simply by making random moves.
