Traditional Chinese Medicine has been used in the treatment of disease for centuries, although its potency is often overlooked by researchers. Dr Yu-Ling Ma and colleagues in the Oxford Chinese Medicine Research Centre at the University of Oxford have focused on a multi-component herbal medicine called Xin Su Ning in the treatment of cardiac arrhythmia to elucidate the mechanism of action and pharmacological properties of its components.

By stacking layers of atom-thick materials on top of each other, researchers are opening up a whole host of exciting new possibilities for technology and scientific research. Particularly interesting properties in these 2D materials could be achieved by stacking three or more of these layers – but so far, the large-scale production of these structures has proven difficult. Using carefully applied techniques, Dr Jakub Sitek and his team at Warsaw University of Technology have made important steps towards overcoming this challenge.

Interactions between positive and negative ions are important processes in nature. However, there is a lack of experimental facilities designed to study them in detail. This picture could now be changing thanks to DESIREE: a facility where different ion beams can be stored and cooled for extensive periods within separate rings, before colliding with each other. Run by an extensive team of physicists at Stockholm University, the instrument is shedding new light on how ions interact in a wide range of environments – from dynamic stellar atmospheres, to interstellar space.

Over recent decades, the use of digital technologies has increased exponentially worldwide, bringing significant changes to daily life. Like most societal transformations, this process of ‘digitalisation’ has had both positive and negative aspects. Dr Jens Allwood, Professor Emeritus at the University of Gothenburg, has recently published a paper exploring some of the darker elements of digitalisation, particularly focusing on its tendency to dehumanise our daily activities.

The introduction of new research or technologies for public health into a community is often challenging since complex scientific concepts coupled with jargon can cause disengagement and mistrust, whilst language barriers and cultural differences can complicate things further. Target Malaria is a not-for-profit research consortium that aims to develop and share new, cost-effective and sustainable genetic technologies to modify mosquitoes and reduce malaria transmission. Stakeholder engagement is one of Target Malaria’s three pillars. Researchers at Target Malaria co-developed with local communities a common glossary to improve engagement on new genetic approaches for malaria control in Burkina Faso, Mali and Uganda.

The broad dissemination of information online has made students more inclined to question what they are being taught in the classroom. Many educators are thus trying to adapt their teaching strategies to ensure that new generations successfully acquire new skills and learn new knowledge. Dr Brenton Fredericks, Head of the Communication Sciences Department at Central University of Technology in South Africa, recently developed a framework that could improve communication between educators and students in the classroom, promoting more constructive and effective learning.

Our daily lives involve periods fluctuating between physical activity and sedentary behaviour, but few studies have researched what motivates us to take on these states from one moment to another. Dr Matthew Stults-Kolehmainen at Yale-New Haven Hospital and Columbia University in the USA, has analysed research from a range of scientific fields to assess the role of urges, cravings, wants and desires on our motivation for physical activity, exercise and sedentarism. He has developed a model to explain how these factors interact, as well as a tool to measure the subjective feeling of these states.

Gyroscopes are widely used to measure the orientations and rotation speeds of moving objects – but according to one pair of researchers, the techniques we currently use to measure them are introducing significant and easily avoidable errors. Through their research, Dr Sara Stančin | Dr Sašo Tomažič, both at the University of Ljubljana in Slovenia, introduce a mathematical framework which accounts for how all three rotations measured by a gyroscope happen simultaneously, rather than in a sequence.

The magnetic field that enshrouds Earth is generated by processes deep within the planet’s interior, which geologists still don’t fully understand. Among the effects that remain poorly studied are brief variations in the strength of the magnetic field, which occur over timescales of several decades. Through detailed mathematical analysis, Dr Klaudio Peqini and Professor Bejo Duka, both at the University of Tirana in Albania, explore how these variations could arise from changes in the flows of material at the boundary between Earth’s core, and its thick layer of mantle.

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.
