Turning trash into treasure

Dumped waste, from used nappies to industrial by-products, have long wound up in landfills and can take hundreds of years to decay. In October we speak to the scientists figuring out how to keep such items in use to reduce rubbish and create a so-called circular economy. We learn about new efforts to mine industrial waste for the rare metals that go into making aircraft parts, pacemakers and bicycle gears, and find out about the culture shift needed to develop a zero-waste society. We also speak to the researchers building a biorefinery to turn soiled nappies into fertilisers and raw materials, and look at whether seaweed could become the next plastic.

The expanding universe

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.

Emotions have long been explored by artists, but new work by scientists is helping us understand more about how we feel. Image credit - Flickr/David Gaines, licensed under CC BY-ND 2.0

More than a feeling

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.

What’s the matter?

Neon lights, astrophysics, lightning and, of course, televisions – plasma is all around us. But what exactly is it and how can we harness its power? This month, Horizon takes an in-depth look at the fourth state of matter, finding out how it could be used to fix environmental problems such as wastewater contamination and factory emissions. We speak to the scientists who are attempting to use plasma energy to create more powerful particle accelerators and probe the mysteries of the universe. We also find out how researchers are trying to recreate astrophysical plasma in their labs and investigate the potential of cold plasma to save lives.

Body re-building

Regenerative medicine takes a different approach to treating disease by aiming to regrow, repair or replace tissues and organs to restore their normal functions instead of just treating symptoms. This month, Horizon takes a deeper look at the promise of this emerging field and takes stock of where we are now. We look at how scientists are beginning human trials of a technique that repurposes cells from one part of the body to treat disorders in another, and find out how 3D printing is helping to tackle arthritis. We also look at the challenges of mass producing the raw materials for regenerative medicine - stem cells - and some of the regulatory and ethical issues that are emerging as the industry develops.

Keeping an eye on Earth

Every minute, satellites and sensors collect enormous amounts of data about the world around us – from temperature to pollution and forest cover to soil quality. This month, Horizon looks into the technologies behind Earth observation and how we can make best use of the vast amounts of information produced. We find out how measurements taken by people with smartphones on the ground can feed into local datasets and how the minituarisation of satellites is creating opportunities for start-ups to enter the Earth observation market. We also discover how measurements are being used to protect ecosystems and what historical data can tell us about extreme weather such as hurricanes and droughts.

In deep water

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.

Digging into Europe's past

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 future of the nine to five

The way we work is undergoing a major shift thanks to technological development and demographic change and, this month, Horizon looks at how research is helping us stay ahead of the game. We find out how decisions made early in your career could determine when you retire, and how to get the most out of the relationship between humans and machines in factories. We also investigate some of the ethical issues that could arise in the jobs of the future and how best to take them into account.

The science of shuteye

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.
