Take a look back at many of the most fascinating science stories of 2017, a year full of stunning advancements in individual fields of study, from astronomy to biology, geology to history – when we piece these discoveries together we see the year in a new light.

A decade after An Inconvenient Truth brought climate change into the heart of popular culture comes the riveting and rousing follow-up that shows just how close we are to a real energy revolution. Vice President Al Gore continues his tireless fight, traveling around the world training an army of climate champions and influencing international climate policy. Cameras follow him behind the scenes-in moments private and public, funny and poignant-as he pursues the empowering notion that while the stakes have never been higher, the perils of climate change can be overcome with human ingenuity and passion.
Renowned filmmakers Bonni Cohen and Jon Shenk have taken the baton from 2006 Academy Award-winner Davis Guggenheim. What started then as a profound slide show lecture has become a gorgeously cinematic excursion. Our extraordinary former vice president invites us along on an inspirational journey across the globe that delivers the tools to heal our planet. The question is: Will we choose to take the baton?

The film is a first of its kind that will transform how we think about engineering. From the Great Wall of China and the world's tallest buildings to underwater robots, solar cars and smart, sustainable cities, DREAM BIG celebrates the human ingenuity behind engineering marvels big and small, and shows how engineers push the limits of innovation in unexpected and amazing ways.
With its inspiring stories of human grit and aspiration, and extraordinary visuals , the film reveals the compassion and creativity that drive engineers to create better lives for people and a more sustainable future for us all. Narrated by Jeff Bridges.

Dark energy - the mysterious force that is unexpectedly causing the universe's expansion to speed up. The effects of dark energy were discovered in 1998 but physicists still don't know what it is. Worse, its very existence calls into question Albert Einstein's general theory of relativity - the cornerstone of modern physics. The hunt for the identity of dark energy is on". Experiments on earth and in space generate data that might provide a clue, but there are also hopes that another Einstein might emerge - someone who can write a new theory explaining the mystery of the dark energy.

Could we get all our energy needs from sea water and the salt it contains? Are we to witness a time when salt will power our engines and factories, and light up our cities? Could this be the final curtain not only for shale gas and oil, but also the burning of fossil fuels and the beginning of a gentler form of energy that is definitely renewable? This documentary explores the latest research on sea water and the way scientists all over the world are working on 'Blue Energy'. This research could bring about a major change in our time.

The film captures the global challenge to lead the clean energy future by profiling U.S. and Chinese workers and business leaders who are racing to make crucial breakthroughs in the field. Catching the Sun debunks a false dilemma that clean energy requires sacrificing economic prosperity.
Through the stories of an unemployed American worker, a Tea Party activist, and a Chinese solar entrepreneur, we will explore the global energy transition from the perspective of workers and entrepreneurs building solutions to income inequality and climate change with their own hands. Their successes and failures speak to one of the biggest questions of our time: will the countries actually be able to build a clean energy economy?
