As Europeans head to the beaches for their summer holidays, Horizon takes a look at the science of the Mediterranean.
For our Sea, Sun … and Science issue we speak to the scientists who helped develop the idea for a synchrotron being built in the Middle East and bringing together researchers from across the region.
We interview a researcher who discovered unexpectedly large swarms of jellyfish in the Mediterranean while checking ocean acidity. And we find out how smart biosensors could help prevent contamination of drinking water.
We also look at the best way to avoid colliding with whales if you are navigating a cargo ship, and hear from Tim O’Higgins, a man who believes the value of the seas can’t just be measured by markets.
Dr Tim O'Higgins, coordinator of the EU-funded KnowSeas project, based in Oban, Scotland, argues that implementation of the EU Integrated Maritime Policy will require a delicate balance between the use of Europe’s seas and conservation of the maritime ecosystem.
A third of a million Europeans get ill every year from diseases caused by contaminated water. Researchers now hope that smart biosensors can help them develop an early warning system that can prevent infection by raising the alarm long before contaminated floodwater reaches people’s drinking water supplies.
In November, Horizon takes a deep dive into the captivating, diverse world of clouds to understand what they mean for climate change. We speak to atmospheric physicist Prof. Pier Siebesma about why clouds are still one of the biggest sources of uncertainty when it comes to climate change and how new field studies are helping to reduce some of the unknowns. We speak to a researcher about flying through tropical clouds to collect particles at high altitudes to paint a full picture of the role of clouds and aerosols in our planet’s climate. And we also delve into research investigating how global warming is changing clouds and why this could bring about extreme weather and rain, and we look at how aerosols – crucial for cloud formation - are changing due to anthropogenic pollution.
In October, Horizon discovers a futuristic world of transparent e-books, plastic solar cells and electronic skin with a look at some of the applications of organic electronics. We speak to organic chemist Prof. Andreas Hirsch about how using carbon rather than silicon in electronics can make them flexible, lightweight and biocompatible and could lead to a new generation of human-looking robots and ‘chemical’ computing. We take a look at work to create electronic skin – self-healing, stretchable material that can mimic some of the functions of human skin – and its potential uses. We discover how thin, flexible, plastic solar cells could turn surfaces such as cars and fabric into sources of renewable energy, and we uncover some novel approaches to charging wearable electronics.
Live vaccines can give health effects beyond just protecting us from a specific disease and may even help us combat other infections such as Covid-19, according to Christine Stabell Benn, a professor in global health at the University of Southern Denmark.
Using light as an energy source, photosynthetic microalgae can be used to produce products like biofuels and cosmetics. But algae grown in a reactor block out the light on which they feed. New reactor designs could solve this problem and help the industry move forward.
Prof. Christine Stabell Benn is studying the wider effects of common vaccines.
Stephan Borrmann’s detective work required help from a high-altitude former spy plane.
Dr Kate Rychert studies ocean plate structures.
