Regular naps may be one of the privileges of retirement but research is pointing to napping as a contributor to cognitive decline. Scientists are now testing the idea that older people should instead meditate or learn a language to preserve brainpower and wellbeing.
A study of more than half a million blood samples has allowed scientists to pinpoint the risk factors for a rare type of leukaemia, enabling them to predict if someone will develop the disease eight years before symptoms appear and opening the door to preventative treatments.
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.
Melting sea ice, plastic waste, biodiversity loss – the Arctic is facing unprecedented environmental pressure and will continue to change until 2050 even if we meet targets to limit global warming, according to Marianne Kroglund from the Arctic Council, an intergovernmental forum addressing the challenges faced by Arctic governments and indigenous peoples.
The fight against terrorism-related content and illegal financing online is speeding up thanks to new platforms that join up different internet-scouring technologies to create a comprehensive picture of terrorist activity.
An ‘internet of electricity’, zero-carbon cities and turning European soils into carbon sinks are among a slew of ambitious ideas to decarbonise our society and slash greenhouse gas emissions proposed by environmental experts in a report published on 28 November.
At first glance, it almost sounds crazy. Can we really take carbon dioxide emissions from an industrial plant and store them underground? To find out, research is currently taking place to test if such an idea is not only viable but safe, and prove that to the public.
The European Open Science Cloud (EOSC), a virtual one-stop shop for researchers to share, access and reuse data, was officially unveiled at the University of Vienna, Austria, on 23 November, giving scientists, open data advocates, research institutions and policymakers a first glimpse of the portal.
Scientists have created a solar atlas of Egypt, revealing where the sun’s rays shine most brilliantly and where dust storms obstruct its light. And in Niger, forecasters are guiding pastoralists towards grazing areas and water sources – and away from conflict with sedentary farmers.
Sandwiching an oxygen-rich layer of silicon between a solar cell and its metal contact has allowed researchers in Europe to break performance records for the efficiency with which silicon solar cells convert sunlight into electricity. But the challenge now is how to make these so-called passivating contacts suitable for mass production.
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.
