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.
The anti-tumour properties of chemotherapy drugs could work twice as well if you take them at times when the body is most receptive, but that means different timetables for different people, according to researchers working to understand how to use the body’s daily rhythms to make medicine optimally effective and reduce unpleasant side effects.
Sleeping, eating and even going to the bathroom, our bodies are clearly affected by the time of day. But the cycle of the moon could also have impacts on our biological functions, according to Professor Kristin Teßmar-Raible, at the Max F. Perutz Laboratories, University of Vienna, Austria, who is leading LUNAR.CLOCK, a project funded by the EU's European Research Council exploring how the moon affects marine organisms.
Keeping calorie-burning brown fat cells running throughout the day rather than allowing them to switch on and off, possibly via tablets or injections, could help our bodies cope better with a modern day abundance of food, according to researchers who are investigating the link between the body clock and obesity.
Plants can override their own body clocks in times of stress, hijacking their programmed activities in a last-ditch attempt to survive, according to researchers who believe their work could change the way we think about internal timing.
It's been 15 years since the euro came into circulation and to mark the occasion Horizon is looking at what the future could have in store for finance. We talk to one economist who says the way to avoid another crisis is to keep banks small and boring, and we explore the effect of alternative local currencies on supporting small businesses. We also delve into some of the technology that could enable us to move to a cashless society, and we look at the growth of the so-called sharing economy, in which people share access to resources.
This December marks one year on from the Paris agreement, where world governments agreed to keep global warming to within 2 degrees Celsius of the average pre-industrial temperature. To mark the occasion, Horizon takes stock of the situation and examines the challenges ahead. We speak to scientists who are mapping a pathway for governments to cut back on emissions, we host a debate on steel - one of Europe’s most polluting industries, and we look the progress of carbon capture and storage. We also interview Professor Hans Joachim Schellnhuber, founder of the Potsdam Institute in Germany, who was the first to propose that 2 degrees should be set as a limit for global warming.
In the province of Limburg, in northeastern Belgium, residents earn points by helping out in the community which they can spend on cinema tickets or trips to the local swimming pool.
The increase is partly driven by climate challenges.
Neuroimaging techniques are helping us read the pictures in our heads.
There is unlimited kinetic energy all around us and harnessing it could change the way we interact with the world, says Dr Gonzalo Murillo.
