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.
The model of our universe as expanding at an accelerated rate has given rise to theoretical constructs such as dark energy and dark matter, which scientists believe could make up 95% of the universe. In September, Horizon takes a deeper look at what we really know about the expanding universe. We speak to Prof. Subir Sarkar, who believes that the Nobel-winning discovery that universe expansion acceleration could be a fluke, and the scientists who are trying to answer the question by allowing us to better measure the expansion rate. We also look at the significance of accurately measuring gravity in deep space, and what dark matter haloes can tell us about the existence of dark energy.
This month, Horizon takes an in-depth look at a shared human trait – our emotions. We find out how science is seeking to better understand and regulate human emotions across a range of applications, from mental health to politics. We uncover the implications of a neuroscientist’s efforts to determine how the brain controls fear and anxiety, with possible implications for treating mental health disorders and autism. We explore how emotions shape our politics and ask whether this can help provide a different perspective on the Israeli-Palestinian conflict. And we look at research examining how apps and online games can help people manage their emotional sides.
A new space telescope designed to peer into some of the farthest regions of the universe could finally answer one of the most puzzling questions surrounding Albert Einstein’s general theory of relativity.
One of the biggest drawbacks of electric vehicles – that they require hours and hours to charge – could be obliterated by a new type of liquid battery that is roughly ten times more energy-dense than existing models, according to Professor Lee Cronin, the Regius Chair of Chemistry at the University of Glasgow, UK.
New observations may provide alternative explanations for dark energy.
The technology could work with existing infrastructures, says Prof. Lee Cronin
We need to double-check the evidence on dark energy, as it may not exist at all, says Prof. Subir Sarkar.
