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.
The world’s oceans are overfished, polluted and – for something that makes up 70% of the Earth’s surface – still little understood. This month, Horizon looks at some of the science that could help us take better care of our oceans, from robots trash collectors out at sea to finding ways to track the plastic that enters our waters. Plus, we look at how climate change is affecting plans for sustainable aquaculture, tech that can help divers reduce the cost of their dives by more than 50%, and the challenges facing research in the Black Sea.
To mark the European year of cultural heritage, Horizon explores how science is helping to uncover more about our past and to preserve our art, landscapes, buildings and ways of life for the future. We discover why prehistoric humans chose to paint rock art where they did, and how farming techniques from hundreds of years ago could help fight climate change today. Plus, we learn how cultural heritage feeds into European identities and what can be done to prevent the destruction of historical sites during wartime.
The world’s largest radio telescope, known as the Square Kilometre Array (SKA) and situated over two continents, will be able to detect the first stars and galaxies emerging from the ‘murk’ at the beginning of the universe and much more besides, according to Professor Phil Diamond, Director General of SKA. He spoke to Horizon at the opening of the Shared Sky art exhibition in Brussels, Belgium on 16 April, where indigenous artists from SKA host nations South Africa and Australia use traditional painting and folk art to explore the themes of astronomy, spirituality and a borderless sky.
Electric ferries and digital communication between ships could help in the quest to decarbonise maritime transport, a sector which is often perceived as being the green option but could still do much to lower its environmental footprint.
Astronomers could use giant radio telescope from 2025.
New tech could help shrink shipping emissions.
