Neuroscientist Dr Domenica Bueti often plays an altered version of the classic aria La donna è mobile when she gives talks about the importance of time perception. Her friend’s piano rendition of Giuseppe Verdi’s composition uses the same notes but is played at different speeds. Rarely does anyone ever identify the tune.
Scientists are getting closer to understanding how to turn the body’s energy-storing white fat cells into energy-burning beige fat cells, opening up hopes that fat deposits could one day be deliberately manipulated to prevent obesity and related health conditions.
They are fleeing war, famine and persecution, risking treacherous journeys across deserts and seas in search of safety. But helping refugees and asylum seekers to cope with the psychological scars caused by their experiences could help them adjust to life in their new homes.
To help prevent organ rejection, transplant recipients could receive drug cocktails personalised to their own immune systems if a new test, which has passed early trials, is successful. And new methods for scrubbing animal tissue could enable humans to benefit from other species’ organs in the future.
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.
The number of parasites is increasing with rising sea temperatures.
Alternatives include robotic couriers and an ‘Uber’ for parcels.
Prof. J Murray Roberts is carrying out a health check on the Atlantic.
