Dr Benjamin Bradley | Cause, Consequence, and Natural Selection: A New Vision of Darwin’s Psychological Work
The theory of evolution by natural selection stands at the heart of modern biology. But what exactly is the causal status of natural selection in evolution? Dr Benjamin Bradley from Charles Sturt University in Australia is challenging long-held assumptions, arguing that Darwin himself saw natural selection as a consequence of other processes, not a cause of evolution in its own right. This crucial distinction opens up new perspectives on how evolution relates to psychology and behaviour.
Dr David Nairn | Time-Interleaved Analogue-to-Digital Converters: Breaking Speed Barriers in Digital Signal Processing
In our increasingly digital world, the ability to convert analogue signals into digital data quickly and accurately is crucial for everything from mobile phones to medical devices. Dr David Nairn from the University of Waterloo, Ontario, has been at the forefront of developing and improving time-interleaved analogue-to-digital converter technology to enable faster and more efficient digital signal processing. His work is helping to overcome key challenges in high-speed digital systems, paving the way for more advanced electronic devices.
Dr. Petr Kelbich | Investigating Inflammatory Conditions in Extravascular Body Fluids: An Important New Parameter
Diagnosing disorders of the brain and other organs can often feel like solving a challenging puzzle. Analyzing non-blood body fluids provides valuable clues that can help address this complexity. To enhance this process, Dr. Petr Kelbich from Jan Evangelista Purkyně University and Masaryk Hospital in Ústí nad Labem, Czech Republic, introduced an innovative method called Cytological-Energy Analysis.
Dr Michelle Pantoya | More Bang for Your Buck: How Changing the Chemical Properties of Aluminum Particles Increases their Power
Aluminum particles are widely used in various energy generating applications, such as fuels. However, due to their high reactivity with atmospheric oxygen, they must be coated in a chemical ‘shell’ in order to prevent spontaneous combustion. This highly protective shell obstructs oxygen from reaching the aluminum core, limiting aluminum’s potential to produce power. Dr Michelle Pantoya from Texas Tech University has led a research team to explore alternative shell compositions. New shell chemistry has exciting implications for aluminum use in rocket fuels and other propellants.

Lisa Smith – Timothy Frankenberger | Building Resilience in Ethiopia’s Drylands: Evaluating Programme Impacts
Developing countries face increasingly destructive crises, including climate, economic, political and health shocks. To improve quality of life and encourage further international development, it is imperative to improve resilience in communities. In recent research, Lisa Smith and Timothy Frankenberger at TANGO International evaluated a programme which aimed to increase resilience among pastoralists and agro-pastoralists in the drylands of Ethiopia. Their discussion includes important recommendations for the design of future programmes.
Dr Susan Kennedy | Understanding Substance Abuse in College Students
Substance abuse in college students is a particular concern. Dr Susan Kennedy, Department of Psychology at Denison University in Ohio, USA, recently led a collaboration with colleagues from the Ohio State University and Kenyon College to explore alcohol and drug use in college students. More specifically, Dr Kennedy and the team wanted to identify at-risk groups and promote student well-being.

Open access vs Public access the case for democratic outreach in academic communication
While the move towards open access and its benefit to the wider scientific community is laudable, it comes at a cost—a cost, like most publishing costs in academia, that is ultimately funded by the general public. In 2023, approximately 45% of academic papers were published as open access. This figure represents a continuation of the growth trend seen in open access publishing over the past decade. This figure is based on all OA models: fully open access (gold), green (self-archived), bronze (free to read without a clear license), and hybrid models. Approximately $2.25 billion of public funds were spent to make those academic papers open access.
