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 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.
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.
Earthworms and tiny water fleas could help deliver clean water to billions of people living in remote areas of the world by eating up sewage and other pollution.
A sister and brother who created shock-activated protective gear featuring a starch liquid for people who in-line skate, motorcycle and do other risky sports, won one of the three first prizes at this year’s European Union Contest for Young Scientists (EUCYS).
Biofilters offer in-situ low-maintenance ways of treating wastewater.
Winners from Germany and Canada take home top prizes.
Electric cars with liquid batteries could be charged in minutes, says Prof. Cronin.
