Regenerative medicine takes a different approach to treating disease by aiming to regrow, repair or replace tissues and organs to restore their normal functions instead of just treating symptoms. This month, Horizon takes a deeper look at the promise of this emerging field and takes stock of where we are now. We look at how scientists are beginning human trials of a technique that repurposes cells from one part of the body to treat disorders in another, and find out how 3D printing is helping to tackle arthritis. We also look at the challenges of mass producing the raw materials for regenerative medicine - stem cells - and some of the regulatory and ethical issues that are emerging as the industry develops.
Regenerative medicine should be governed, firstly, by the principle of do no harm, but a better balance between risk and regulation is required to bring innovations to market more quickly, according to Ton Rabelink, professor of internal medicine and head of nephrology at Leiden University in the Netherlands. He says that Europe is in danger of falling behind countries such as Japan and the US if there is not more flexibility in how new therapies are regulated.
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.
Neon lights, astrophysics, lightning and, of course, televisions – plasma is all around us. But what exactly is it and how can we harness its power? This month, Horizon takes an in-depth look at the fourth state of matter, finding out how it could be used to fix environmental problems such as wastewater contamination and factory emissions. We speak to the scientists who are attempting to use plasma energy to create more powerful particle accelerators and probe the mysteries of the universe. We also find out how researchers are trying to recreate astrophysical plasma in their labs and investigate the potential of cold plasma to save lives.
Workshops focusing on intergroup emotions are showing how deeply-rooted beliefs can be changed to support conflict resolution.
The impact of heavy droughts, heatwaves and cold spells on energy demand and supplies would be lessened with seasonal climate forecasts that allow energy companies to better predict spikes in usage ahead of time, researchers say.
Psychological and physiological interventions are tackling intolerance for others.
Longer notice of extreme weather would help cap prices.
We need to adopt 100 solutions, says Project Drawdown vice president
