Peter Day's World of Business

Since Bletchley Park and the enigma machine, Britain has been at the forefront of what would become cyber security. In GCHQ we have a world leader in threat detection and yet our industry lags far behind both the US and Israel. Jonty Bloom looks at what we could do to make this Brexit proof industry bigger and finds out why Belfast is at the forefront of the UK’s research and development to keep us safe online. He looks at Unit 8200 the Israeli Army’s elite cyber security unit which has spun off several successful start up companies because of the unique training system they employ. Jonty gets to see inside the National Cyber Security Centre which is part of GCHQ’s new open policy as it invites investors to see the third round of it’s start up incubator. The ‘Catalyst’ campus in Belfast’s newly redeveloped docks sits beside the shipyard that built the Titanic and is now securing silicon chips rather than building ships. It’s buzzing as foreign investment has flowed into to take advantage of its burgeoning cyber security talent pool. A bet placed on the industry a decade ago by Queen’s University has paid off with a pipeline of graduates with the specialist skills needed to protect us online. Each and every heartbeat is unique to its owner and Jonty meets a company using this to secure our information as well as our cars. Getting the chance to test drive their heart beat steering wheel with some disastrous consequences. No trip to Belfast would be complete without a trip to the pub and here we meet some of the young talent that’s drawing this attention. We hear how quickly the start-up culture has grown and how this tech cluster has reached a level that is reversing the once chronic brain drain from the region.

Potholes are a national obsession. But there's much more to them than you might think. Ruth Alexander digs deep into their costs for business and society - where fixing two holes in a motorway can cost half a million pounds. But she also finds all kinds of entrepreneurial imagination going into solving the problem. Everything from new data analysis to 3D printing drones may be the answer. Beneath it all lies a fundamental question. Can we learn to value roads, and maintain them as a vital national asset, smoothing the way to big business and social gains?

Does the house building industry need to change? Manuela Saragosa meets the disruptors, the companies trying to transform how the vast majority of residential property is built. Across the country new factories are springing up - in a bid to manufacture our homes in much the same way as we do our cars. The risks are huge. Significant investment is required to get things moving and demand for these new homes has yet to be tested. But the disruptors claim that the house building industry must modernise or die. Productivity is falling and traditional skills are in short supply - something that is likely to get worse as immigration reduces. Other countries, too, already build huge numbers of homes off-site, claiming that this results in quicker and cheaper construction. So, just how many of the hundreds of thousands of homes that we need to build might end up being factory produced? Presenter: Manuela Saragosa Producer: Rosamund Jones Picture Credit: BBC

It’s been a challenging year on Britain’s railways with timetable chaos, over-running engineering works, cancelled trains and irate passengers, not to mention a private operator handing back control to the government. The transport secretary, Chris Grayling has announced yet another review of the industry. Meanwhile, Labour and many of the public want to see rail re-nationalised. Rail professionals point to the industry’s successes – a doubling in passenger numbers since privatisation, and a current strong safety record. But the government says the rail industry hasn’t kept pace with customer demand. So is there another way? Matthew Gwyther goes to Italy to experience their take on free competition on their high speed lines. He also speaks to rail experts at home – all searching for answers.

From innovative mattresses to personal sleep consultants, business is moving in on our nights under the covers. The sector is booming, thanks to a new understanding of the importance of sleep, with annual sales in the billions of pounds. And it’s not only our homes that businesses are targeting. In the workplace, managers are becoming more aware of the sleep needs of their teams and some are even installing pods to allow their employees to have a nap on the job. David Baker looks at the products and services on offer and finds out how we can separate the science from the snake oil.
