Across the globe, climate change is driving extreme weather events, such as floods and droughts, with increasing frequency, duration, and intensity. Accurately assessing the flow of water through rivers – or river discharge – could help us forecast extreme weather events and prevent loss of life. Sensors onboard satellites could provide more accurate and in-depth measurements of river variables than ever before. As part of the RIDESAT project, funded by the European Space Agency, Dr Angelica Tarpanelli and her team of researchers from Italy and Denmark investigate how combining remote sensing data from satellites could support river discharge assessments.

This is a recounting of a scientific investigation into a mysterious but potentially deadly disease that first came to light principally in the Balkan states, and then several Asian countries. It manifests itself first as a nephropathy resulting in the destruction of kidney tissue often followed by a cancer of the upper urothelial tract. Professors Arthur Grollman and Francis Johnson at Stony Brook University have achieved a revolutionary understanding of the molecular biology, epidemiology and root cause of both diseases. Their findings have critical implications for medical and scientific communities, as well as the general public.

Since the beginning of the COVID-19 pandemic, billions of plastic facemasks have been used and disposed of, with the majority destined for landfill. Professor Andrew R. Barron and his team at the Energy Safety Research Institute in Swansea, Wales, have developed an innovative method for repurposing these used facemasks. By transforming them into a powdered material that acts as a reducing agent, Professor Barron’s team aim to make the steel-making process more energy-efficient and sustainable.

Wide-area scans of the sky are an important tool for astronomers as they seek to learn more about the universe. However, as the latest observation techniques have become increasingly sensitive, faint objects within these surveys can appear to blend together. Through his research, Dr Peter Melchior at Princeton University presents a computer-based framework for disentangling these blended sources, and for artificially reconstructing the components they contain. Named SCARLET, the technique could soon help astronomers to study the depths of the observable universe in unprecedented levels of detail.

Dr Brett Lidbury from the Australian National University worked with colleagues to utilise machine learning techniques in a new strategy to identify biomarkers that could be used to help diagnose myalgic encephalomyelitis/chronic fatigue syndrome in patients. Their work represents a significant step forward in understanding, diagnosing and treating this challenging condition, particularly in relation to pathology, the results of which form a routine but important part of general health assessment.

An ancient relationship between plants and fungi could help us improve forestry and agriculture, while also responding to the challenges posed by climate change. These beneficial fungi, along with their bacteria helpers, help plants to grow bigger and healthier, and survive droughts. An international team of researchers has been investigating how these fungi and bacteria increase mineral availability for Scots pine and red pine seedlings through mineral weathering.

The term literature refers to a wide and diverse range of work, including novels, poems, plays, and essays. While literary experts agree that all literature is composed of language, they often argue about which texts can or should be considered as a part of the literature that we value. In recent years, technological advances have led to the creation of innovative works that merge language with digital media, state-of-the-art technologies and computation itself. In a fascinating book called Grammalepsy, Professor John Cayley of Brown University introduces a new theory of aesthetic linguistic practice that could shed new light on digital literature or, more comprehensively, language art.

Rises in population and demographic changes can have significant effects on the development and governance of urban environments. Associate Professor Glen Searle of the University of Sydney recently published a paper that highlights the ways in which Sydney’s rapid population growth is supported by national immigration targets and the state government’s desire to keep Sydney ahead of other Australian cities as a global city. This population growth then drives important governance decisions at state and national levels, particularly relating to development. By prioritising rapid dwelling construction to accommodate Sydney’s rising population, but lacking adequate funding for new transport, the state government has had to reduce checks and balances needed for more democratic planning and sustainable development.

Italy was the first European country to experience a major outbreak of COVID-19. Across the country, intriguingly different patterns of mortality were seen across regions. Dr. Marzia Cremona from Université Laval, in collaboration with a global team of researchers from the Pennsylvania State University and the Sant’Anna School of Advanced Studies, used novel statistical tools from the field of functional data analysis (FDA) to identify several important factors contributing to these differences. This work has critical implications for policymaking and also demonstrates the useful application of FDA techniques to epidemiological research.

From its early days, the field of chemistry has been exploring nature at the molecular level. As such, chemistry is also used to explore natural resources and possible ways of exploiting them. As Earth’s environment is now rapidly deteriorating, chemists need to adapt their practices with the aim of contributing to its protection. Dr Surjani Wonorahardjo, Dr Suharti Suharti and Dr I Wayan Dasna, three researchers in Indonesia, have recently conducted a study exploring the ethical and environmental issues associated with current chemistry practices, in the hope to inspire reflection and positive change in the field.
