Artificial intelligence and virtual assistants are constantly being refined, and may soon be making appointments for you, offering medical advice, or trying to sell you a bottle of wine. Although AI technology has miles to go to develop social skills on par with ours, some AI has shown impressive language understanding and can complete relatively complex interactive tasks. In several 2018 demonstrations, Google's AI made haircut and restaurant reservations without receptionists realising they were talking with a non-human.

Andrew Ng has called it the "new electricity" while Google CEO Sundar Pichai even went beyond that: "artificial intelligence is going to have a bigger impact on the world than some of the most ubiquitous innovations in history", like electricity (sorry Andrew…) and even fire. So, I feel pretty confident to state that AI will lie at the basis of the (re-)development of business, and even society in general. If the world wide web built the substructure of the age of networks and disruption, then AI will drive the same type of revolution in the cognitive age. Google, Apple, Facebook, Amazon, Alibaba, IBM: everyone is racing to get a piece of that very delectable and rich pie. But who will win the race?

Amazon has successfully conducted drone deliveries in England, but consumers across the Atlantic have yet to witness it in action – until now. The e-commerce giant showed off its Prime Air drone to the public during a conference in California by dropping off a box containing a bottle of sunscreen.

The firm said its drones will deliver packages 30 minutes or less while flying at speeds of 50 mph.

The modest eyeless roundworm appears to have the remarkable superhero-like ability to taste light. A new type of cell has been discovered in the taste receptors of these creatures which is about 50 times more efficient at capturing light than the human eye. Scientists say that the unusual characteristics of the receptor could be used in a range of applications, including creating more effective sunscreens. It might sound like a power only superheroes could have, but the modest eyeless roundworm has the ability to taste light. Animal photoreceptors usually have two components – a base protein, and a light-absorbing chromophore.
