If people are the lifeblood of cities, then transport links are its veins and arteries. If they're cut off, the city will die. Thousands of people work every day at making it possible for city dwellers to be where they need to be, when they need to be there. It's an endless demand of brain and brawn. Without the army of drivers, diggers, and planners, our great cities would come to a halt.

Electricity powers the life support systems that keep our cities running. Lights, transport, communications, and even hospitals rely on this invisible force. Without it, our cities come to a standstill and lives are put at risk. Meet the people who spend tireless hours to make sure that city power grids remain safe, efficient, and uninterrupted

Food- human life can't exist without it. It's a city's most important source of energy. In New York alone, 8 million people consume 10,000 tonnes of food every day. Without new supplies, cities will run out of fresh food in a matter of days.

The world's cities are growing at a faster rate than ever before. An estimated 75 million people around the world move to an urban area every year. And as our metropolises become more and more crowded, architects, designers, and builders face a constant challenge.

For centuries, cities have been built near a fresh water supply. Without water, we'd be lucky to live three days. This most basic human need can be deadly too... the wrong supply can poison us, or get too close or careless and it can drown thousands in an instant. With every passing year, the challenge of providing water to billions of people becomes harder and harder.

The promise of quantum computers is that what would otherwise take a billion years to calculate, could be done in a few seconds. First-generation quantum computers have started to appear. Indeed, earlier this year, Google bought one, The D-Wave 2. How will this advance change our future lives?

One of the ancient world's most iconic buildings, the Colosseum is a monument to Roman imperial power and cruelty. Its graceful lines and harmonious proportions concealed a highly efficient design and advanced construction methods that made hundreds of arches out of 100,000 tons of stone. In its elliptical arena, tens of thousands of gladiators, slaves, prisoners, and wild animals met their deaths. Ancient texts report lions and elephants emerging from beneath the floor, as if by magic, to ravage gladiators and people condemned to death. Then, just as quickly, the Colosseum could be flooded with so much water that ships could engage in sea battles to the delight of the crowd.

The Sun is our star. Its energy enables life on the Earth to thrive yet we know so little about the solar weather and the 11-year solar cycle. Modern technology can be adversely affected by giant coronal mass ejections and there appears to be a link between sunspot activity and climatic conditions.
