Could machines, technologies and devices made with micro-organisms and bacterial cells soon be a part of our daily lives? Will modified cells be a part of the medical treatments we take, the food we eat, the fuels we use?
November’s issue of Horizon takes a look at the cutting-edge technologies known as synthetic biology which are bringing together engineering and biology to create completely new systems and innovations.
We hear how bacteria can be turned into electricity-generating cells and even change how we take our medicines.
In this issue, we speak to researchers who are using synthetic biology to augment our bodily systems by, for example, adapting cells so that they release hormones that make us feel full when they sense too much fat in our blood.
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 sister and brother who created shock-activated protective gear featuring a starch liquid for people who in-line skate, motorcycle and do other risky sports, won one of the three first prizes at this year’s European Union Contest for Young Scientists (EUCYS).
Winners from Germany and Canada take home top prizes.
New observations may provide alternative explanations for dark energy.
We need to double-check the evidence on dark energy, as it may not exist at all, says Prof. Subir Sarkar.
