Cointegration of causes of mortality as a possible measure of human ageing
Many of us can expect to live longer than previous generations. We might also surmise that one of the top five causes of mortality will prove our demise. Ultimately, however, most causes of death are linked to ageing, an inevitable process for which we have no direct measurement. Professor Séverine Arnold, of the University of Lausanne, has provided a potential […]
Electron paramagnetic resonance: EPR everywhere
Electron paramagnetic resonance (EPR) measures the signal from unpaired electrons and is a technique already widely used in the bioscience and pharmaceutical industries. Dr Joshua R. Biller of TDA Research, Inc, USA is championing the novel use of EPR to answer research questions. He explains that rapid innovations in EPR will allow a wider group of researchers to image tumours, […]
When the body turns against itself: Amyloid-based diseases
Often, the body is its own worst enemy. Diseases such as cancer are caused by faults in the natural replication processes of our own cells. It is thought that both Parkinson’s and Alzheimer’s disease may be caused by amyloids – aggregates of our own proteins that can disrupt nerve signalling and other functions. Dr H. Robert Guy of Amyloid Research […]
Protecting bottlenose dolphins from coastal construction
Professor Ann Weaver of Good-Natured Statistics Consulting, USA, has studied dolphins living free at sea for 20 years. Her numerous scientific discoveries about dolphin behaviour yield ample evidence of intelligence and of sophisticated social behaviour at sea. Drawing from many years of intensive studies in primates, she undertook an impressive 18-year ethological study of the social behaviour and impact of […]
Covid-19 highlights the importance of defibrillation in in-hospital resuscitation
Many aspects of the healthcare system have changed as a result of the COVID-19 pandemic, including the response to cardiac arrests both outside and within hospitals. Early recognition of cardiopulmonary arrest, early defibrillation when indicated, and early advanced life support (ALS) are some of the common practices that fall under in-hospital resuscitation. John A. Stewart, an independent researcher and retired […]
The role of values in social innovation transfer
What role do values play in knowledge transfer between social enterprises, and what are the factors which facilitate or inhibit the exchange of innovative practice? Those are the questions behind new research by Imran Chowdhury of Wheaton College in Massachusetts, USA. Looking at social entrepreneurship through the lens of a partnership to transfer a model of affordable eye-care services from […]
Training a new generation of problem solvers: Innovation in STEM education
Humankind faces unprecedented environmental, social, and economic challenges. There is a critical need for STEM education to foster both science learning and the application of learning to problem solving. At the University of Utah, Professor Nancy Butler Songer and her collaborators have developed a suite of interdisciplinary instructional and field-based data collection resources offering elementary and secondary students the chance […]
Online laboratories and Cross-Reality in engineering education
COVID-19 has compelled educators to rapidly transition to online learning methods. This shift is particularly challenging for instructors whose courses involve hands-on laboratory instruction. In his research, Dr Dominik May, an Assistant Professor in the Engineering Education Transformations Institute at the University of Georgia, has been focusing on online laboratories and Cross-Reality learning spaces in engineering education for over a […]
Synchronisation in symmetrically and asymmetrically coupled oscillators
Complex networks are systems composed of several components which may interact with each other. Examples range from laser arrays to the human brain, global climate, and digital communication forms. The behaviour of complex systems depends upon the internal dynamics of the individual unit, communication among cells, type of coupling between them, and symmetry. Dr Antonio Palacios from San Diego State […]
Nonoverlap proportion and the point-biserial association problem
Dr Stanley Luck, a statistics consultant and founding member of Vector Analytics LLC, has developed a novel algorithm for cloud computing technology. Dr Luck demonstrates the use of his improved CART association algorithm in a high-dimensional search problem of nursing home performance, based on the publicly accessible Nursing Home Compare (NHC) database. The results highlight the importance of constructing a […]
