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.
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.
The chemistry behind social behaviour in animals, including the bond between people and dogs – and the lack of one between humans and wolves – could help scientists identify new ways of treating social disorders such as autism and schizophrenia.
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.
Decades of scientific research into areas including plant genetics and data science helped doctors successfully carry out an experimental therapy to create a new skin for a seven-year-old boy suffering from a rare genetic disorder.
Rising populations and climate change are putting pressure on the water needed for agriculture but a solar-powered irrigation system may reduce the amount that farmers use – while simultaneously slashing the sector’s greenhouse gas emissions.
How plant genetics and data science helped doctors replace 80 % of a boy’s skin.
Solar-powered irrigation could offset 16 mn tonnes of CO2 a year.
A new device to monitor so-called ultradian rhythms could speed up diagnostics.
