A single microscopic brain cell cannot think, is not conscious, but if you bring in a few more brain cells, and a few more, and connect them all, at a certain point, the group itself will be able to think and experience emotions and have opinions and a personality and know that it exists. How can such astonishing things be made from such simple ingredients? Well, answering that question means learning not only who we are but, more importantly, how we are.
Today, using what neuroscientists know so far, we are going to make a town function like a brain, using people as neurons.

In the fifth episode we will see from counterfeit Beanie Babies to very real tax crime. One person wonders if could make refunds in the name of dead people. It turns out that it can.
We will also see an attempted fraud by two hackers to the IRS: the United States federal agency in charge of tax collection. These skilled hackers revisit cyber schemes that landed them in the sight of law enforcement.

In this sixth and final episode, the FBI escalates its pursuit of an elusive hacker, but he soon turns the tables by questioning the legality of a key tool in their investigation.
We'll also find out how one man is being watched by the government for alleged Russian election interference. Is he responsible, or just a patsy for more powerful people? We'll have to get to the end to find out.

In this historical drama, the turbulent transition from Roman republic to autocratic empire, which changed world history through civil war and wars of conquest, is sketched both from the aristocratic viewpoint of Julius Caesar, his family, his adopted successor Octavian Augustus, and their political allies and adversaries, and from the politically naive viewpoint of a few ordinary Romans, notably the soldiers Lucius Vorenus and Titus Pullo and their families.
'The Stolen Eagle.' In Gaul in 52 B.C., two Roman soldiers, Legionary Titus Pullo and Centurion Lucius Vorenus, are tasked with recovering Julius Caesar's personal Eagle, stolen from his camp in the dead of night. With his campaign in Gaul coming to a successful conclusion, Caesar's popularity is continuing to grow. He's saddened however when he receives news from his good friend Pompey Magnus that his daughter, Pompey's wife, has died in childbirth. In the Senate, Pompey must defend the prolonged absence of his friend and co-Consul Caesar against charges of corruption.

Deep in the Bolivian Andes at the height of 13,000ft stands Tiwanaku, the awe-inspiring ruins of a monolithic temple city. Built by a civilisation who dominated a vast swathe of South America, it was abandoned 1,000 years ago. For centuries it has been a mystery - how did a civilisation flourish at such an altitude and why did it vanish? Jago Cooper journeys through Bolivia's spectacular landscape to investigate the origins of Tiwanaku and finds evidence of an ancient people with amazing understanding of their environment, whose religion was based on collective effort and ritual beer drinking.

Michael Wood embarks on a great historical adventure, exploring the stories, people and landscapes that have helped create China's distinctive character and genius over four thousand years. Is the history of the world's newest superpower, from its ancient past to the present day.
Starting in Wuxi, Michael joins the Qin family reunion, when 300 relatives gather to worship their ancestors on Tomb Sweeping Day. 'Like the nation, the family has been through so much,' one says. 'Now everyone wants to know - what are our roots?'
Looking for the origins of the Chinese state, he visits the excavations at Erlitou and sees an exquisite turquoise dragon sceptre from 2000 BC. China's first writing is found on 'oracle bones' dug up from the Shang royal tombs at Anyang in the 1920s. At the Beijing Planetarium, Michael travels back in time as astronomers plot the planetary conjunction that the ancients believed foretold the overthrow of the Shang Dynasty. Next, the Age of Philosophers and Confucius, whose book Analects has had greater influence worldwide than even the Bible, according to some. In Xi'an, we hear how the First Emperor united China and created the authoritarian Qin state that gave us the word China. Finally, Michael returns to the temple fair in Henan for a dramatic night ceremony to give thanks to the ancestors. China, Michael concludes, is rising again, not just because of its economic strength, but because of the incredible solidarity of the Han Chinese view of their own civilisation, their sense of family and, of course, the presence of the ancestors.
