In the 1997 Robin Williams flick Flubber, an absent-minded professor creates a sentient ball of goo with incredible capabilities. Now, more than 25 years later, scientists have made a surprising discovery that could bring Flubber into the real world. Researchers from the University of Reading have created a non-living'hydrogel brain' which is capable of playing the video game Pong. Using a plate of electrodes hooked up to the classic game, the water-based jelly even managed to get 10 per cent better as it practised. While it might not be quite as bouncy as Robin Williams' invention, the researchers believe this breakthrough could change the future of artificial intelligence.

An inanimate glob of ion-laced jelly can play the computer game Pong and even improve over time. Researchers plan further experiments to explore whether it can handle more complex computations and hope it could eventually be used to control robots. Inspired by previous research that used brain cells in a dish to play Pong, Vincent Strong and his colleagues at the University of Reading, UK, decided to try playing the tennis-like game with an even simpler material. They took a polymer material containing water and laced it with ions to make it responsive to electrical stimuli. When electricity is passed through the material, those ions move to the source of the current, dragging water with them and causing the gel to swell.

The deal has yet to be approved by the relevant regulators, but Google has got most of the way to buying Fitbit – the maker of wearable devices that track people's sleep, heart rates, activity levels and more. And all for a trifling $2.1bn (£1.6bn).The upshot is yet another step forward in Google's quest to break into big tech's next frontier: healthcare. Last month, in a Financial Times feature about all this, came a remarkable quote from a partner at Health Advances, a Massachusetts-based tech consulting company. Wearables, he reckoned, would be only one small part of the ensuing story: just as important were – and no guffawing at the back, please – "bedside devices, under-mattress sensors, [and] sensors integrated into toilet seats". Such inventions, it was explained, can "get even closer to you than your smartphone, and detect conditions such as depression or heart-rate variability".
