They control everything and they ve done nothing for our region, no education, no health, no transport", says the Deputy Commander-in-Chief of the TNLA. Northern Myanmar is home to some of the longest lasting insurgencies in the world. It is also one of the world s main production sites for opium, heroin and methamphetamines. The TNLA have launched an offensive against drug production in their homeland which they suspect is run by the Pansay, an ethnic Chinese militia. "We haven t seen any development in our land. It is all because of drugs. We lost everything", says one soldier. The TNLA battle against the Myanmar government also continues, as they are excluded from negotiations for a nationwide cease-fire agreement. One young soldier explains: "It s time for us to rise up and fight back. I will give my life and die in the battlefield... I am a Taang".

Subscribe to Naked Science – https://goo.gl/wpc2Q1 Ours is said to be a Godless age, yet billions remain faithful to religions thousands of years old. Scientist Colin Blakemore examines Christianity s relationship with science, arguing that science is the biggest challenge Christianity has ever faced. For more than 1,500 years Christians saw the bible as the primary source of knowledge, but in the 17th century a new movement emerged that challenged the Christian view of the world, the Scientific Revolution. During the Renaissance the rising power of science forced the Catholic Church to silence rebellious scientists. By the 19th century the enlightenment had given rise to a new generation of scientists who pushed Christianity into retreat. If science continues to make discoveries that conflict with Christian Doctrine will the Scientific Revolution ultimately make Christianity redundant? "Christianity: A History" is a documentary series presenting alternative views on the history of the Christian faith, looking at its origins, development and turbulent past. High profile British personalities examine a religion that has particular resonance for them. In doing so, they bring their own perspectives to a challenging and comprehensive debate that explores Christianity s role in shaping the modern world.

Italy was a major European country that joined World War 1 almost a year after the assassination of Archduke Franz Ferdinand in Sarajevo. Initially, Italy actually had an alliance with Germany and Austria-Hungary called the Triple Alliance, but Italy decided to back the Entente powers instead because they were promised disputed land in the Alps and near Trieste.

New Zealand has one of the highest rates of gang membership per had of population in the world. They have forged a reputation for violence and illegal activities, but many now represent changing times. "We are not exactly the pillars of society. We understand that", explains Jamie Pink, leader of the Tribal Huk gang. But now, a new initiative by gang members is seeing them make and deliver free sandwiches children who would otherwise go without. "It gives you a reason to get up the next day", explains Pink. And while it will be hard to shake off their anti-social image, many like school principal Maria Hamill are starting to come round to the idea: "I think actions speak louder than words."

The Great Retreat of the Russians during the last weeks has shown one thing: Artillery is the key to success. More specifically, a new kind of artillery tactic called the artillery barrage which focuses shelling on one part of the front. August von Mackensen had actually stolen this approach from John French. The Entente tried to use it on the Western Front a few months earlier without the expected breakthrough. » PARTNER CHANNELS DER ERSTE WELTKRIEG: http://bit.ly/1wkyt IT’S HISTORY: http://bit.ly/ITSHISTORYSHOW » HOW CAN I SUPPORT YOUR CHANNEL?
