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.
Hormones are blamed for everything from weight gain to mood swings and this December, Horizon takes a closer look at these chemical regulators and their effects on our bodies and minds. We explore the impact of the so-called love hormone on the human-dog relationship and what it can tell us about social disorders. We find out what’s being done to neutralise the hormone-disrupting chemicals that are found in water and sewage, and we discover the importance of hormonal rhythms in tracking disorders that can lead to obesity, heart disease and osteoporosis.
Forests cover around 30 % of the Earth’s surface, are home to millions of species, capture and store carbon dioxide (CO2), influence the local climate and provide us with water. This month, Horizon examines how the health of the world’s forests impacts on climate change. We explore the link between deforestation, forest degradation and CO2 emissions, examine the push to combine farming and forestry for better land management, and find out how scientists are using tree rings and DNA to combat illegal logging.
Hormonal disorders can affect people's immune systems, metabolism and even bones, and unravelling the mystery around something called ultradian rhythms could help improve diagnosis and lead to better treatments, according to Professor Eystein Sverre Husebye, who works at the Department of Clinical Science at the University of Bergen (UiB) in Norway.
Monitoring ultradian rhythms could speed up diagnosis.
