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.
Most children are able to learn language almost effortlessly. But for those with communication disorders such as dyslexia, mastering their native tongue can be a challenge. Researchers are exploring how links with noise, language and motion could help diagnose problems earlier and pave the way for better treatment.
Europe’s minority languages have been squeezed by nation-building, urbanisation and the ‘lingua francas’ of the internet, according to Professor Anneli Sarhimaa, specialist in Northern European and Baltic languages and cultures at the University of Mainz, Germany. But one lesson she has learned from researching the fate of the Finnic language Karelian, spoken in Finland and north-western Russia, is that digital media can also help revitalise them.
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.
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.
From high winds and heavy rainfall to droughts and plummeting temperatures, people in Europe have already begun to feel the effects of extreme weather. As we get used to this new reality, scientists are investigating how it will affect how we get around and whether our infrastructure can cope.
Increasingly severe weather could cripple our roads and railways. Here’s how we’re getting ready.
There is no evidence that language skills prevent cognitive decline, say researchers.
More regulations won't prevent drone disruption, says security expert Dan Hermansen.
