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.
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.
The world is losing its trees, but at what cost? Better estimates of deforestation and degradation could shed light on the amount of CO2 emitted, refine climate models and help developing countries better manage their forests.
Understanding more about how solar storms interact with the outermost part of Earth's environment, known as the foreshock, could refine space weather forecasts to predict their effects at a local level and help protect vital technology, according to Dr Lucile Turc, a space physicist at the University of Helsinki, Finland.
New measurements of carbon emissions provide better estimates of deforestation effects.
Illegal logging is a billion-euro racket but trees have traceability built into their trunks.
Better space weather forecasts will help.
