As fundamental components of our electronic and optical devices, semiconductors are essential to our modern way of life. Dr Yasuo Koide of the National Institute for Material Science in Japan has an extensive history of researching and developing these unique materials. Alongside his colleagues, Dr Koide continues to break through the boundaries of our existing knowledge to create new and exciting technologies.

For thousands of years, the notion of a one-way flow of cause-and-effect has underpinned virtually every scientific theory. Yet Dr Martin Tamm at the University of Stockholm argues that this notion of ‘causality’ may be holding back our understanding of how the Universe really works. Through his research, he suggests an alternative approach, based around a mathematical construct named ‘probability space’. His ideas could ultimately lead to new solutions to problems that physicists have struggled with for decades.

Synapse elimination is a tightly regulated process, and an aberrant number of synapses both during the early stages of development or later in aging, has been observed in several neurological conditions, including Alzheimer’s disease, schizophrenia or autism. Effective methodological approaches for investigating how supernumerary synapses and apoptotic material are removed from the brain are vital for understanding the underlying mechanisms, and this, in turn, may provide exciting avenues for the development of new treatments. Dr Morini, Dr Filipello and colleagues at Humanitas University and at Washington University in St Louis have recently published a review about the different strategies and tools available to study the role of microglia, the phagocytes of the brain, in neuronal and synaptic substrates phagocytosis.

Enshrouding the Martian surface with thick clouds of dust, the Red Planet’s unique global dust storms have long mystified astronomers and planetary scientists. James Shirley, at NASA’s Jet Propulsion Laboratory, has shown through his research that the occurrence of these global storms is strongly linked to the changes in Mars’ motion about the gravitational centre of the solar system. Already boasting strong observational evidence, his results could not only improve our understanding of the Mars atmosphere – they may also lead to a better understanding of turbulent weather patterns on Earth.

Although the number of women enrolling in science, technology, engineering and math (STEM) courses has increased over the past few years, women still remain widely underrepresented in STEM fields. To address this serious issue, the HBCU-HDI Women in STEM Conference, an event organised by Dr Sonya Smith and her colleagues at Howard University, brings female scientists and graduate students from the US and South Africa together to openly discuss the challenges and opportunities for women pursuing careers in STEM-related fields.

The Galapagos Islands are facing increasing danger. Local and global forces – including tourism and climate change – threaten the fragile island ecosystems. The high number of unique plants and animals on the islands means that the loss of a Galapagos species may represent a global extinction event. The Galapagos Initiative, founded by Dr Stephen Walsh of the University of North Carolina at Chapel Hill and Dr Carlos Mena of the Universidad San Francisco de Quito, aims to save the Galapagos Islands with an innovative, sustainable strategy combining evidence from key interdisciplinary projects and a robust mapping and modelling program.

Being overweight is a well-recognised risk factor for the development of chronic diseases such as diabetes, heart diseases, and certain types of cancer. As such, obesity represents a significant public health issue worldwide. It is the leading cause of death in the USA, notably in Arkansas, where Dr Jamie I. Baum, at the Department of Food Science at the University of Arkansas, is exploring, with her colleagues, the relationship between dietary protein intake and its impact on body composition and metabolism to develop efficient nutritional guidelines to prevent and treat obesity.

Magnetic monopoles have long been dismissed as impossible by many physicists, but their existence has nonetheless been theorised for many decades. Through their extensive research, scientists at Terra Quantum AG, the University of Perugia, and SwissScientific Technologies, show that the end could soon be in sight for this conflict. The team’s investigations into superconducting materials not only show that magnetic monopoles must be real – their discoveries also set the stage for exciting technological advances.

The far-reaching benefits of nanopore research encompass fields as diverse as physics, healthcare, big data processing and environmental studies. At the University of Illinois at Urbana-Champaign, Dr Jean-Pierre Leburton is conducting research focused on the use of nanopores in ultrathin solid-state molecular materials, such as graphene and 2D transition-metal dichalcogenides, for DNA sensing applications. This offers a low-cost and highly effective method of identifying biomolecules, and could have widespread medical applications, enabling rapid, early and effective disease diagnosis and prompting effective treatment, as well as providing invaluable technologies for assisting with DNA sequencing.

The spaces in between galaxies may be unimaginably vast, but within galactic clusters, they are far from empty. Rather, these expanses are home to a wide range of interplaying, often violent plasma dynamics. In his research, Dr Tom Jones at the University of Minnesota plans to use cutting-edge computer techniques to simulate these processes – shedding new light on physical properties that have eluded astronomers so far. His team’s research will not only give crucial insights into some of the largest structures in the known universe, but will also capture the public imagination, and inspire a diverse new generation of astronomers.
