Can a galaxy really die? What would that even look like? We know that stars can erupt into supernova, form black holes or fade away but what happens to old galaxies? What happens to a galaxy when it looses all it's fuel for growing new stars? Which galaxies are the most active and pulsing with light? Active galaxies often shine vibrantly from their core, but what causes periodic bursts of energy. NASA Goddarrd researchers have discovered the 'Old Faithful' of Galaxies.

You've probably heard of CRISPR, but what does it mean for the world of professional sports? How could gene-doping be detected by sports administrators? Could you tell if someone had used CRISPR to 'dope' their performance? WADA considers gene editing a form of doping, but how can you detect it? What happens when you mix sweat, gym equipment and cleaning products? When you exercise you release a 3-5 times the amount of chemicals than a sedentary person. What happens to the mix of sweat, amino acids and cleaning products in the air of a gym?

Waiting for glue to cure can take a long time, but can magnets speed it up? We use epoxy to glue together so much of the modern world, but it takes a lot of energy to cure it. Is there a way to make epoxy glues more 'energy efficient' with magnets? Magnetically activate glues can literally stick your shoes together. Gears are one of the most fundamental mechanical elements, can we get chemicals to form gears themselves. A 1mm thick sheet with some chemicals and you can get gears to form themselves. Small gear trains and mechanical motion can power soft and flexible machines.
