Detecting diseases, removing CO2 from chemicals and uncovering the composition of the earth’s core: diamonds have many more uses than just decorating our hands. This January, Horizon talks to the researchers who are unearthing new ways of using one of nature’s most treasured materials.
New experiments that crush material between two diamonds to simulate the extraordinarily high temperatures and pressures found in the earth's interior are providing answers to the age-old questions of what our planet is made of, and where its ingredients came from.
As the clocks go back this October, Horizon takes a moment to look at the 24-hour rhythms that govern life. We talk to scientists trying to alter the internal clocks of our cells to help fight obesity and diabetes, and others working out the best time for each patient to take medicines. We also learn how tobacco plants can change their body clocks in a last-ditch attempt to survive when they’re threatened by predators or food scarcity.
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.
The United Nation’s declaration on the future of the world’s cities, known as the Quito Declaration, will mean that citizens’ needs are placed at the heart of the urban development process, according to Dr Niki Frantzeskaki, an associate professor at the Dutch Research Institute for Transitions (DRIFT) at Erasmus University in Rotterdam, the Netherlands.
In Rotterdam, residents have helped create floating buildings.
Prof. Kristin Teßmar-Raible is studying how the lunar clock affects bristle worms and what that could mean for us.
