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.
Investigators should capitalise more on the fact that terrorist cells often work with criminal organisations to achieve their goals, according to Dr Matteo Bonfanti, a senior researcher at the Center for Security Studies at ETH Zurich in Switzerland.
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.
