Gaia Vince takes you for a mosey around his year's Summer Science Exhibition, held by London's Royal Society. Along the way, PRS Sir Adrian Smith talks of reforming A-Levels and a sorry international science collaboration situation as many european research grants are terminated amidst a Brexit withdrawal agreement stand-offs.

The Royal Society Summer Science Exhibition is on until Sunday 10th July, it is free to attend and there are many activities and events online too.
