Language lessons

The languages we speak and how we speak them are an integral part of our identity, shaping not only how we see the world but also how people see us. In January, Horizon puts language under the spotlight, kicking off the month with a look at Europe’s minority languages and how to preserve them. We also delve into the social and cognitive aspects of language use, finding out how accents arise and how they affect people’s perception of the speaker, and discovering how ageing affects linguistic capacity in bilingual people – and vice versa. We also speak to researchers looking into the language impairment dyslexia and potential options for early diagnosis.

On thin ice

When it comes to climate change, it is often said that what happens in the Arctic does not stay in the Arctic. This month, with the COP24 UN climate change conference taking place in Katowice, Poland, Horizon looks north to the region of the world that is feeling the effects of global warming most acutely. We speak to Marianne Kroglund from the Arctic Council about whether it is too late to save the fragile ecosystems there and examine how studies of ice melt show that the world may still have a fighting chance of limiting sea level rise. We find out how the Arctic environment could be protected in the face of increased maritime traffic and look at the effect of melting permafrost – soil, sediment or rock that’s been frozen for at least two years – on the environment and local communities.

Capturing carbon

In its landmark report in October, the UN's International Panel on Climate Change said that every package of measures we choose to limit global temperature rises to 1.5°C must include a way of removing carbon dioxide emissions from the air and reusing or storing them. This month, Horizon looks at what's being done to advance these carbon capture, storage and utilisation technologies. We talk to one expert who is trying to trap emissions from the cement industry before they are released, and find out how International Space Station technology is inspiring the capture of ambient carbon dioxide. We also investigate how captured CO2 can be reused, and examine just how safe it is to store the gas underground.

Turning trash into treasure

Dumped waste, from used nappies to industrial by-products, have long wound up in landfills and can take hundreds of years to decay. In October we speak to the scientists figuring out how to keep such items in use to reduce rubbish and create a so-called circular economy. We learn about new efforts to mine industrial waste for the rare metals that go into making aircraft parts, pacemakers and bicycle gears, and find out about the culture shift needed to develop a zero-waste society. We also speak to the researchers building a biorefinery to turn soiled nappies into fertilisers and raw materials, and look at whether seaweed could become the next plastic.

The expanding universe

The model of our universe as expanding at an accelerated rate has given rise to theoretical constructs such as dark energy and dark matter, which scientists believe could make up 95% of the universe. In September, Horizon takes a deeper look at what we really know about the expanding universe. We speak to Prof. Subir Sarkar, who believes that the Nobel-winning discovery that universe expansion acceleration could be a fluke, and the scientists who are trying to answer the question by allowing us to better measure the expansion rate. We also look at the significance of accurately measuring gravity in deep space, and what dark matter haloes can tell us about the existence of dark energy.

More than a feeling

This month, Horizon takes an in-depth look at a shared human trait – our emotions. We find out how science is seeking to better understand and regulate human emotions across a range of applications, from mental health to politics. We uncover the implications of a neuroscientist’s efforts to determine how the brain controls fear and anxiety, with possible implications for treating mental health disorders and autism. We explore how emotions shape our politics and ask whether this can help provide a different perspective on the Israeli-Palestinian conflict. And we look at research examining how apps and online games can help people manage their emotional sides.

What’s the matter?

Neon lights, astrophysics, lightning and, of course, televisions – plasma is all around us. But what exactly is it and how can we harness its power? This month, Horizon takes an in-depth look at the fourth state of matter, finding out how it could be used to fix environmental problems such as wastewater contamination and factory emissions. We speak to the scientists who are attempting to use plasma energy to create more powerful particle accelerators and probe the mysteries of the universe. We also find out how researchers are trying to recreate astrophysical plasma in their labs and investigate the potential of cold plasma to save lives.

Body re-building

Regenerative medicine takes a different approach to treating disease by aiming to regrow, repair or replace tissues and organs to restore their normal functions instead of just treating symptoms. This month, Horizon takes a deeper look at the promise of this emerging field and takes stock of where we are now. We look at how scientists are beginning human trials of a technique that repurposes cells from one part of the body to treat disorders in another, and find out how 3D printing is helping to tackle arthritis. We also look at the challenges of mass producing the raw materials for regenerative medicine - stem cells - and some of the regulatory and ethical issues that are emerging as the industry develops.

Keeping an eye on Earth

Every minute, satellites and sensors collect enormous amounts of data about the world around us – from temperature to pollution and forest cover to soil quality. This month, Horizon looks into the technologies behind Earth observation and how we can make best use of the vast amounts of information produced. We find out how measurements taken by people with smartphones on the ground can feed into local datasets and how the minituarisation of satellites is creating opportunities for start-ups to enter the Earth observation market. We also discover how measurements are being used to protect ecosystems and what historical data can tell us about extreme weather such as hurricanes and droughts.

In deep water

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.
