May 2023
Stanford Magazine

Introduction
Dive into the heart of Senegal with Stanford ecologist Giulio De Leo, where the battle against the parasitic disease schistosomiasis is heating up. With a mix of sweat, science, and snail-eating prawns, De Leo's team is pioneering an eco-friendly solution to a problem that plagues over 200 million people worldwide. Forget conventional medicine; in this high-stakes fight, prawns are the unexpected heroes. Check out the full story in Stanford Magazine for an adventure in innovation and hope.

Prawns vs. Parasites - A Battle for Better Health
Imagine living in a place where a simple dip in the river to cool off or fetch water could lead to a lifetime battling a debilitating disease. This is the reality for millions in sub-Saharan Africa and increasingly elsewhere, due to the parasitic disease schistosomiasis. The story of how researchers, including Giulio De Leo and his team, are turning to nature - specifically, snail-eating prawns - to fight this 'disease of poverty' is not just fascinating, it's a critical lesson in the power of innovative ecological solutions to human health problems. Understanding this battle is crucial because it highlights the interconnectedness of our environment and health, and how changing one part of an ecosystem can have profound effects on disease prevalence. For you, it's a window into how science and creativity can converge to solve real-world problems, demonstrating the importance of thinking outside the box and the potential of ecological approaches to disease control.

Ecological restoration
The process of assisting the recovery of an ecosystem that has been degraded, damaged, or destroyed.
Independent Research Ideas

Exploring the impact of climate change on parasitic diseases
Investigate how rising global temperatures affect the distribution of diseases like schistosomiasis and the survival of their vectors and hosts.

The role of biodiversity in disease prevention
Study how maintaining or restoring biodiversity in certain areas can help in controlling diseases that affect humans.

The economics of biological disease control methods
Analyze the cost-effectiveness of using biological control methods, like prawn introduction, compared to traditional medical treatments.

Cultural perceptions and disease management
Research how local beliefs and practices in different communities affect the implementation and success of disease control measures.

Technology and disease monitoring
Investigate how modern technologies, such as drones and satellite imagery, can improve the monitoring and management of disease vectors in difficult-to-access areas.
