Noisier waters linked to behaviour change, hearing loss in whales

Studies investigating whale-watching boats and the inner ears of marine mammals could soon provide new insight into the effects of noisier oceans on cetaceans – dolphins, whales and porpoises – who depend on their hearing for navigating, finding food and communicating underwater.

Why we may be able to save the Greenland ice sheet

Studies of ice melt in the Arctic suggest that the world may have a fighting chance of preventing huge sea level changes that would result from the dramatic collapse of the vast ice sheets that cover Greenland, but that more work is needed to understand the wider effects.

Offshore wind farms to test business in deep water

As wind turbines become increasingly familiar sights along shorelines, developers of offshore floating platforms, which harness the powerful winds further out to sea, are seeking to establish their technologies as a major viable source of clean energy.

Hydrogen-powered boat plots course for the future of ocean travel

The first day that Jérôme Delafosse stepped aboard the Energy Observer, an experimental catamaran run on hydrogen, he knew the plan of sailing around the world on clean energy was a realistic one, he says. Now, the explorer and documentary maker is one year into a six-year odyssey around the globe with his friend Victorien Erussard, an ocean racer and former cruise ship officer, to prove that the technology can be used for pollution-free ocean travel in the future.

Lessons from a real Atlantis

Traces of long-forgotten human settlements claimed by the sea thousands of years ago are being uncovered by researchers along the coastlines of Europe.

Sticky tape and simulations help assess microplastic risk

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.

Electric ferries and joined-up shipping to turn sea travel green

Electric ferries and digital communication between ships could help in the quest to decarbonise maritime transport, a sector which is often perceived as being the green option but could still do much to lower its environmental footprint.

Scientists explore underwater frontiers with submersible tablet computers

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.

Europe must sea food in a new way thanks to warming waters

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?

Modern-day malnutrition

How did European eating habits go so wrong? We have a plentiful supply of fresh food yet, according to Eurostat, one in every two people in Europe is either overweight or obese, leading to problems such as cardiovascular disease, high blood pressure and lifestyle-related diabetes. In May, we delve into the complex science of healthy eating to understand how to tackle modern-day malnutrition. We speak to public health expert Knut-Inge Klepp about the complex factors determining food choice and how to improve the diet of teenagers. We find out how scientists are working to improve the zinc content of crops to prevent the ‘hidden hunger’ of micronutrient deficiency and look at the importance of widening the diversity of grains that we eat – both for our health and for the environment. We also explore what’s behind the nutritional self-sabotage of eating disorders.

Political science

As May’s European elections approach, Horizon takes a step back to see what science can tell us about European politics. We look at the latest research into people’s opinions about the EU and how they’ve changed, particularly in response to the financial crisis of 2008, and ask what needs to be done to bring the public closer to politicians. We speak to cryptography expert Dr Steve Kremer about why most of us can’t vote online yet, and democracy specialist Prof. Wolfgang Merkel about the changing political party structures in Europe and whether this is a threat to democracy. We also find out how scientists are working to detect and flag fake news on social media in order to increase the transparency of the information people encounter online.

Chemical mixtures pose ‘underestimated’ risk to human health say scientists

Each of us harbours hundreds of man-made chemicals inside our bodies because we are exposed to them in our daily lives. While individual chemicals may not be of immediate concern to public health, scientists now worry that certain mixtures of them may pose previously underestimated risks to health.

‘Teenagers are going to be the ones to beat childhood obesity’

Teenagers rarely have a say in the public health policies that concern them, but we can’t halt the childhood obesity problem without working with them, says Professor Knut-Inge Klepp, executive director of the mental and physical health division at the Norwegian Institute of Public Health.
