By assembling a camera that can record video at nanometre resolution, scientists have filmed how the immune system kills bacteria by poking holes into it. Professor Georg Fantner tells us about how this was achieved and why his next challenge is to build a video camera that can film the inside of a living cell.
When you hear the word ‘quantum’, you may imagine physicists working on a new ground breaking theory. Or perhaps you’ve read about quantum computers and how they might change the world. But one lesser-known field is also starting to reap the benefits of the quantum realm – medicine.
Each of us harbours hundreds of man-made chemicals inside our bodies because we are exposed to them in our daily lives. While individual chemicals may not be of immediate concern to public health, scientists now worry that certain mixtures of them may pose previously underestimated risks to health.
Teenagers rarely have a say in the public health policies that concern them, but we can’t halt the childhood obesity problem without working with them, says Professor Knut-Inge Klepp, executive director of the mental and physical health division at the Norwegian Institute of Public Health.
In remote, rural corners of Malawi, hospitals are often faced with life-and-death decisions. Women in need of emergency caesarean sections, older people with hernias, and children with appendicitis need surgery. But should they be rushed to the operating theatre or transferred to specialists in city hospitals?
Mice that have undergone weight loss surgery experience a change in the composition of their gut bacteria and the functioning of their genes, leading scientists to explore the possibility of mimicking these changes to develop a non-surgical treatment for obesity and liver disease in humans.
Next-generation wheelchairs could incorporate brain-controlled robotic arms and rentable add-on motors in order to help people with disabilities more easily carry out daily tasks or get around a city.
Countries across Europe are committing to carbon neutrality. But what are the big issues?
The environmental impact of AI must be assessed, say experts.
Jean-Eric Paquet tells Horizon how a new annual event - Research & Innovation Days - aims to shape European research over the next 8 years.
