In our mission of connecting science and society, our new format celebrates the critical role of multi- and interdisciplinary approaches in propelling creativity and innovation, as well as the fundamental importance of advancing the expansion of ideas, broadening perspectives, and promoting new ways of thinking by furthering inclusivity and diversity.

Restoring Earth’s ecosystems and ensuring global food security are two of the greatest challenges humanity has ever faced. These puzzles are even more challenging in the face of climate change and a growing human population. In this important issue of Scientia, we meet scientists who are tackling these challenges head on. The first half of the issue showcases the work of ecologists and conservation scientists, whose research is informing new strategies to protect and restore Earth’s precious biodiversity.

We open this section by speaking with Professor Astrid Groot, President of The European Society for Evolutionary Biology, who explains how evolutionary insights are essential for devising effective conservation plans. Next, we meet many fascinating scientists, each conducting important research in the areas of ecology or evolutionary biology – from identifying the best strategies to protect Louisiana’s wetlands, to exploring how ‘genetic rescue’ can save inbred populations of animals and plants from extinction.

This riveting issue of Scientia provides an exciting insight into the future of health and healthcare with a vast array of new discoveries and innovative technologies in medical science.

This riveting and thought-provoking issue of Scientia showcases the work of scientists charting new frontiers in psychological and brain sciences. The brain is, by far, the most complex organ in the human body. It is responsible for our thoughts, what we do and what we don’t do, our external experience of the world and our internal sense of self. It should not, then, be unexpected that conditions affecting the brain can have deleteriously severe impacts on people’s lives. And at the same time, conditions affecting the brain are notoriously difficult to treat. In our first section, we meet the researchers working to ameliorate the negative impacts of adversity and trauma on mental health. From advances in understanding how childhood trauma impacts brain development to recognition of the complex and interacting factors associated with alcohol use disorders, this section highlights critical advancements being made in building brighter futures through scientific endeavour. Our second section showcases the work of researchers unravelling the complex and multifaceted causes of disease.

This special issue of Scientia is dedicated to the scientists working to confront cancer, one of the biggest challenges facing medical science in the 21st century. Although research into cancer has taken place in some form for over 200 years, still to this day we do not have a cure and cancer remains a leading cause of mortality across the globe. The first section in this special issue is dedicated to research on the causes and risk factors that may lead to cancer, with a focus on the need for public health interventions to reduce preventable deaths. Our second section focuses on the work of researchers striving to improve the timing and accuracy of diagnosing cancer. This is a critical area of research because early diagnosis is associated with much better rates of survival than later diagnosis. Our final section is dedicated to the development of treatments for cancer. In acknowledgement of the need to develop a broad range of therapies to cover the whole spectrum of cancer, we meet the researchers dedicated to the development of novel and innovative therapeutics.

Scientists, engineers, medical professionals and statisticians are all at the forefront of our battle against SARS-CoV-2. As a result, the fields of science, technology, engineering and mathematics (STEM) have perhaps never seemed so important. In addition to eradicating this devastating virus, many other challenges facing society, such as climate change and biodiversity loss, can only be addressed by a strong and diverse STEM workforce. Building a robust STEM community is dependent upon innovative and inclusive education, from primary school to university and beyond. Therefore, this issue showcases an inspiring collection of projects, each seeking to enhance STEM education worldwide.
