The world’s oceans are overfished, polluted and – for something that makes up 70% of the Earth’s surface – still little understood. This month, Horizon looks at some of the science that could help us take better care of our oceans, from robots trash collectors out at sea to finding ways to track the plastic that enters our waters. Plus, we look at how climate change is affecting plans for sustainable aquaculture, tech that can help divers reduce the cost of their dives by more than 50%, and the challenges facing research in the Black Sea.
A team of experienced science divers has created the world’s first submersible touchscreen for a tablet computer, whose applications are already helping marine scientists, law enforcement, explorers and other professionals toil beneath the waves and could usher in a new era of underwater ICT.
Aquaculture, or fish farming, is one of the world's fastest growing food sectors, providing about half of all the fish we eat. As it stands, climate change is altering our ocean’s environment, causing the seawater to become warmer and impacting the marine ecosystems profoundly. How will these changes affect marine species, consumers and industries that rely on them?
A Roomba-like ocean trash collector modelled on a whale shark and a microplastic filter made from jellyfish slime could prevent litter from entering our oceans and help tackle a growing problem that poses threats to wildlife, deters tourists and impacts on coastal economies.
To mark the European year of cultural heritage, Horizon explores how science is helping to uncover more about our past and to preserve our art, landscapes, buildings and ways of life for the future. We discover why prehistoric humans chose to paint rock art where they did, and how farming techniques from hundreds of years ago could help fight climate change today. Plus, we learn how cultural heritage feeds into European identities and what can be done to prevent the destruction of historical sites during wartime.
The way we work is undergoing a major shift thanks to technological development and demographic change and, this month, Horizon looks at how research is helping us stay ahead of the game. We find out how decisions made early in your career could determine when you retire, and how to get the most out of the relationship between humans and machines in factories. We also investigate some of the ethical issues that could arise in the jobs of the future and how best to take them into account.
Tiny pieces of plastic, now ubiquitous in the marine environment, have long been a cause of concern for their ability to absorb toxic substances and potentially penetrate the food chain. Now scientists are beginning to understand the level of threat posed to life, by gauging the extent of marine accumulation and tracking the movement of these contaminants.
The world’s largest radio telescope, known as the Square Kilometre Array (SKA) and situated over two continents, will be able to detect the first stars and galaxies emerging from the ‘murk’ at the beginning of the universe and much more besides, according to Professor Phil Diamond, Director General of SKA. He spoke to Horizon at the opening of the Shared Sky art exhibition in Brussels, Belgium on 16 April, where indigenous artists from SKA host nations South Africa and Australia use traditional painting and folk art to explore the themes of astronomy, spirituality and a borderless sky.
