This month, Horizon explores the weird and wonderful world of 2D materials. We talk to researchers revving up for a nano car race on a track the size of a flu virus, and others who are splicing atom-thick layers to create materials with on-demand properties. We find out how one scientist is bending and stretching 2D materials to create ultra-small sensors, and discover some of the other potential applications creating a buzz, including energy storage and high-power computing.
Bending and stretching 2D materials to change their properties could lead to ultra-small sensors that can help us understand how gravity works at the microscopic scale, according to Professor Kirill Bolotin from Freie Universität Berlin, Germany, who leads the EU-funded Strained2DMaterials project to uncover what happens to 2D materials under strain.
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.
Even though we all spend about a third of our lives asleep, there's still plenty left for us to learn about the science of sleep. This month, Horizon looks at the importance of shuteye for our physical and mental health, and how sleep-deprived brains may be both awake and asleep at the same time. Plus, we investigate what exactly drives us to sleep and wake up, the effects of insomnia, and how the way our bodies use sleep to form memories is inspiring scientists to discover ways to improve our brains.
Mining isn’t the only way to extract valuable metals. Soon, they could increasingly be recovered from waste, reducing the need for new raw materials and helping Europe’s transition to a low-carbon economy.
The future of work is here – and it’s defined by flexibility, autonomy and pressure, according to Prof. Seán Ó Riain from Maynooth University, Ireland, who has been studying how workplaces have changed since 1995. He says we need to rethink public services to help people balance work and family in this new era.
Landfill trash is being turned into industrial treasure.
The 9 to 5 is in decline, presenting problems for work-family balance.
Sleep expert says that around 10 % of people are at risk of insomnia and it is genetically correlated with depression.
