H2O: The Molecule That Made Us
9pm, BBC Four
Some deep-dive geology here as Kelly McEvers presents this three-part series looking at the substance upon which all life on Earth depends. With the help of engaging experts, she shows how water is the link between the organic and mineral world and how dramatically nature has adapted itself to its presence – for example, there are seeds that are primed to wait 30,000 years for even a drop or two to reach them. Fascinating and even slightly mind-bending at times. Phil Harrison

Gossip Girl
10.35pm, BBC One
The definitive millennial NYC high-school drama in which popularity contests are mediated by an unknown blogger is rebooted. As the school year begins, a new student is thrust into a harsh spotlight. A slightly incongruous sense of nostalgia now hangs over the show but, even so, it’s still very watchable. PH
