Sinopsis

Yesterday a small Japanese ion-thruster spaceship arrived at its destination after a three year and half year, 2 billion mile journey. Hyabusa2 is currently floating alongside the asteroid known as 162173 Ryugu. BBC Science Correspondent Jonathan Amos dissects the aims of this audacious sample-return mission and the initial images that have just arrived back on earth. There's a plethora of neutrinos flowing through your body right now. Adam Rutherford goes inside 'protoDune', the world's latest and largest neutrino detector whose prototype is about to be filled with over 700 tonnes of liquid argon and hopefully pick up a few signals generated by interactions from these elusive particles. We hear from project leader Christos Touramanis who is a particle physicist from Liverpool University. Caledonian crows craft tools with greater sophistication than most animals, and can learn to modify their tools to make them gradually more effective. This "cultural accumulation" is commonplace amongst humans - where we
