Facebook's drones - made in Britain

Media captionFacebook's Aquila drone takes to the air

In a warehouse in Somerset, the latest phase in Facebook's bid for world domination has been taking shape.

Or, to put it less dramatically, the social network's plan to connect millions in developing countries is proceeding.

It is called Project Aquila and involves building solar-powered aircraft which will fly for months at a time above remote places, beaming down an internet connection.

Two years ago Facebook bought small British business Ascenta, which specialises in solar-powered drones, and its owner Andy Cox is now the engineer running Project Aquila.

At the end of June, the first aircraft produced in that warehouse on an industrial estate in Bridgwater was dismantled and taken in pieces to Arizona. There, it was reassembled for its first flight.

The government has quietly launched a bold experiment using the technology behind the virtual currency Bitcoin - and, if anybody notices, it could prove hugely controversial. That is because the trial involves the payment of benefits and could conceivably involve very sensitive data being made public - or at least that's the concern of some critics.

There is a huge amount of excitement around now about the Blockchain, with endless academic studies and a good deal of investment reinforcing the belief that a permanent ever-expanding and tamper-proof online ledger of transactions must have all sorts of wider applications.

There is new evidence today of how the UK technology sector is feeling about its future after the referendum vote to leave the EU. And the message from a survey carried out by Tech City UK is pretty gloomy - though the organisation itself sees some reasons for optimism.

Tech City UK got responses from more than 1,200 members of the tech community. Questioned in the immediate aftermath of the referendum, 74% of them said they thought the economy would get worse, not better.

Moorfields, Google - and a problem with sharing

Eye scan

It is a fascinating experiment that brings together Google's artificial intelligence division and one of the world's leading centres for the treatment of eye conditions.

But the research project that has seen Moorfields Hospital hand over retinal scans to DeepMind has already proved controversial - and, for me, it all feels rather close to home.

It is probably not controversial to say that the UK tech scene, and in particular London, was very much in the Remain camp in the EU referendum.

It has long been the most secretive of Britain's intelligence agencies - but, lately, GCHQ has been tiptoeing ever so carefully out of the shadows.

Last month, the signals intelligence operation opened a Twitter account - "Hello World," was its first offering - and last night its director spoke for an hour at an event where he even took questions from members of the public.
