Even though we all spend about a third of our lives asleep, there's still plenty left for us to learn about the science of sleep. This month, Horizon looks at the importance of shuteye for our physical and mental health, and how sleep-deprived brains may be both awake and asleep at the same time. Plus, we investigate what exactly drives us to sleep and wake up, the effects of insomnia, and how the way our bodies use sleep to form memories is inspiring scientists to discover ways to improve our brains.
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.
Did you know there are 200 million insects for each human on the planet? This October, Horizon delves into the mysteries of this diverse set of creatures and their seemingly infinite survival skills. We talk to researchers about why it's vital to maintain the diverse range of insect species, find out how robots and ants can work together to solve problems and explore how the superpowers of bugs could be put to use for humans.
Heart disease kills almost two million people a year in the EU, so it is important to find different ways of keeping your heart healthy. This September, Horizon examines innovative ways of treating heart disease, including electric gene therapy to prevent heart attacks and a miniature heart implant. Plus, we look at how 4D imaging of mice and zebrafish can help regenerate human hearts.
Rare diseases are uncommon, but there are still thousands of different conditions which together affect between 27-36 million people in the EU. This month, Horizon examines the latest efforts to tackle rare diseases as well as new technology to better diagnose uncommon conditions and novel ways to reduce the socioeconomic burden of unusual disorders.
This July, Horizon goes on an investigation to find the latest in how science can catch the bad guys, from recreating crime scenes in virtual reality to hidden cameras that turn on when they spot crime in rural areas. Plus we hear how looking at organised crime could help track down terrorists, and how to keep your information safe, such as through a phone that could recognise the way you swipe.
Robots won’t replace doctors any day soon, but they can already help medical professionals do amazing things. This month, Horizon looks at how robots will someday perform remote physical and ultrasound examinations so doctors can make a diagnosis from a distance, and medical avatars for elderly people that help them stay fit and safe. Plus, we see how computer games could make young people lead healthier lifestyles and how to give self-help apps more scientific merit.
How will we have enough food to feed another 2 billion people by the middle of this century without destroying our planet? Agriculture is already one of the biggest contributors to climate change. This month, we hear from scientists designing disease-resistant crops using gene editing, packing more calcium into finger millet, and resurrecting ancient crop varieties to offset the sector’s environmental impact. Plus, we hear from Dr Manoj Dora about so-called lean agriculture, which is looking to make agriculture more sustainable by eliminating waste from the production process.
Extremophile bacteria have adapted to survive inhospitable niches.
A better understanding of sleep pressure could advance therapies.
Sleep expert says that around 10 % of people are at risk of insomnia and employers should invest in therapy for those affected.
