News: Broken hearts and sleepless flies – How pumping patches of heart muscle cells will soon be repairing broken hearts and why lack of sleep may not be vital, at least in flies.

Fighting fake news – Why do some people trust fake news more than real news, and what can be done to tackle the problem? We meet researchers investigating how the way information spreads can tell us more than its content, and whether regulation or education is the right path to eliminating its influence.

Have a safe flight – As our airspaces get more crowded with commercial flights, private jets and even drones, what can be done to prevent airspace infringements? Ahead of her appearance at our Wonder Women Lates event (7 March) we talk latest technologies and emerging problems with Dr Elena Psyllou from the Centre for Transport Studies.

InSight into Mars – From the excitement of a successful touchdown to the anticipation of detecting the first Marsquake, we catch up with a researcher at the forefront of the new Mars InSight mission and find out what it could tell us about how the planet and the Solar System itself formed.
