The global cyberwar is heating up and the stakes are no longer limited to the virtual world of computers. Now, thanks in part to secret documents released by Edward Snowden, the true scale of the National Security Agency's scope and power is coming to light. Besides spending billions of dollars to ingest and analyze the worlds' electronic communications, the NSA has set out to dominate a new battlefield—cyberspace. We examine the science and technology behind cyber warfare and asks if we are already in the midst of a deadly new arms race". Already, highly sophisticated, stealthy computer programs such as the notorious Stuxnet worm can take over and even destroy the control systems that regulate everything from food factories to gas pipelines, power plants, and chemical facilities—even our cars. While the destruction of Iranian centrifuges may have delayed Iran’s bomb program and forestalled an Israeli attack, the attack has opened a Pandora's Box, and now America's own critical infrastructure is vulnerable to retaliation and attack. With leading defense experts and investigative journalists who have probed the murky realm of criminal and strategic hacking, NOVA examines the chilling new reality of cyberwar in which no nation or individual is safe from attack.

Every day our planet faces cataclysmic events that threaten our very existence. Whether from natural or man-made forces, rising from the earth or menacing from space, the world seems beset by more catastrophes than ever. Some believe the signs of the coming Apocalypse are all around us–as outlined in the bible’s most compelling book of prophecies: Revelation". And even the non-religious can’t ignore what appears to be a growing rate of globe-threatening disasters. Are we approaching a biblical “End of Times”? And if so–how will it happen? Will it come from an act of God? Or a colossal misstep of man? Get an uncomfortably close front row seat to some of the most likely apocalyptic scenarios our world faces today–and the history, both scientific and biblical, behind them.

40,000 years ago the steppes of Eurasia were home to our closest human relative, the Neanderthals. Recent genetic and archaeological discoveries have proven that they were not the dim-witted cave dwellers we long thought they were. In fact, they were cultured, technologically savvy and more like us than we ever imagined! So why did they disappear? We accompany scientists on an exciting search for an answer to this question and come to a startling conclusion... A climate change due to a cataclysmic event.

Directed by Alex Gibney, it follows the life and work of ex-Apple CEO Steve Jobs. Gibney starts the doc by showing how much people around the world worship Steve Jobs as if he were an idol. He then provides you with a wealth of background information about Jobs' childhood, teenage and college years including how he formed Apple Inc. Fortunately, not all of the doc is hagiography because Gibney does briefly delve into the darker side of Jobs, particularly how selfish he was and mistreated those around him including his ex-wife. Jobs comes across as a charming, intelligent narcissist who knows how to captivate an audience whenever he speaks. In other words, like all great narcissists, he's a very good actor. Gibney certainly knows how to choose the right subject because Jobs' complexity makes him all the more captivating and worthy of a feature-length film. As is usually the case with Gibney's docs, this one is slickly-edited and has just the right amount of comic relief, mostly in the brief video of an young boy joyfully lists all of Apple's technological devices that Steve Jobs created. You'll catch a glimpse of what makes Jobs fallible, and find a little mildly provocative food for thought about the advancement of modern technology, i.e. how technology helps to connect us to one another yet alienates us at the same time.

To show what the USA can learn from rest of the world, director Michael Moore playfully visits various nations in Europe and Africa as a one-man "invader" to take their ideas and practices for America. Whether it is Italy with its generous vacation time allotments, France with its gourmet school lunches, German with its industrial policy, Norway and its prison system, Tunisia and its strongly progressive women's policy and Iceland and its strong female presence in government and business among others, Michael Moore discovers there is much that American should emulate
