Heart disease kills almost two million people a year in the EU, so it is important to find different ways of keeping your heart healthy. This September, Horizon examines innovative ways of treating heart disease, including electric gene therapy to prevent heart attacks and a miniature heart implant. Plus, we look at how 4D imaging of mice and zebrafish can help regenerate human hearts.
Around 15 million people across Europe suffer from congestive heart failure, a chronic condition where the heart is not able to pump enough blood around the body, but according to Sofia Marchã, a senior policy officer for patients and research at the European Heart Network in Brussels, Belgium, a new health app could make living with the condition easier.
Real-time imaging of embryonic heart growth and regeneration could uncover the cause of adult heart disease and lead to potential treatments, according to Dr Miguel Torres, a developmental biologist at the Spanish National Centre for Cardiovascular Research.
A miniaturised heart implant is one of the most promising ways in which scientists are hoping to tackle cardiovascular disease, the world’s biggest killer, which claims the lives of almost 2 million people every year in the EU alone.
How do you design and build a robot that you can’t even see? And what would you use it for? In May, Horizon explores the developing field of nanorobotics and its potential applications. We speak to Prof. Brad Nelson at ETH Zurich in Switzerland whose team found that the nanobots they were working on destroyed the drugs they were meant to be delivering, so are now repurposing them to purify water. We speak to researchers who are using the origami-like properties of DNA to make tools such as nanorobotic boxes with lids that open, and others that have created a molecular robotic arm that can pick up, reposition and release molecules. And because tasks like going into a blood vessel to dissolve a dangerous clot would be ideal for a nanorobot, we find out how scientists are devising ways to enable nanorobots to travel through the bloodstream.
The asteroids in our solar system are the remnants of planetary formation. They hold clues about how the Milky Way formed, but they also hold promise and peril for humans as the source of both rich materials and potentially dangerous cratering events. This month we look at the latest in asteroid research. We speak to Dr Naomi Murdoch, a planetary scientist, about her work investigating asteroids, how to land on them and how to defend Earth from a dangerous event. We look in depth at how scientists in the field of planetary defence are developing rapid response techniques to detect an Earth-bound ‘imminent impactor’, determine within days whether it’s dangerous, and evacuate people from the danger zone. We speak to scientists studying exactly what asteroids are composed of so that we can categorise them from Earth, and we look at work studying asteroid dust to see what it can tell us about the early days of our solar system and the origins of life on our planet.
Farmed fish are increasingly becoming vegetarian, with plant-based feed now widely used in Europe. Researchers now want to optimise feed to promote fish growth and nutrition. To do this, they are studying fish gut bacteria and the impact of probiotic additives as well as testing nutrient supplements.
To find out, scientists are investigating fish gut bacteria and feed nutrients.
