Can We Cool the Planet

   2020    Nature
Are rising temperatures driving Earth's ecosystems past a point of no return? We have promising technologies that put solutions within our grasp. Scientists are exploring solutions: from geoengineering to sucking carbon out of the air to cloud brightening, as means to cool the planet. Cutting-edge solutions and high-risk measures. But would they work? And what are the risks of engineering Earth's climate?

Can We Make Life

   2018    Medicine
'It's alive!' Since Dr. Frankenstein spoke those famous words, we've been alternately enthralled and terrified by the idea of creating life in the lab. Now, a revolution in genetic engineering and thrilling innovations in synthetic biology are bringing that dream—or nightmare, as the case may be—closer to reality. New tools allow researchers to use cells to create their own DNA and edit it into existing genomes with more ease and less cost than ever before.
Along with renewed hopes for treating some genetic diseases, there's serious talk of using the newest technologies to bring long-extinct animals back from the dead – like the team hoping to resurrect the woolly mammoth. Science fiction is quickly becoming science fact. Another daring genetic experiment to bioengineer animals could prevent Lyme disease. But the power to make life comes with deep ethical questions. What are the potential rewards—and dangers—of tinkering with nature? This films explores the benefits and the burden of risk surrounding the controversial new technology.

Catching the Sun

   2016    Technology
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?

Changing Planet

   2019    Nature    HD
At a time when the Earth’s surface is changing faster than ever in human history, watch cities grow, forest disappear and glaciers melt.
In the ever-growing grey of cities one man is feeding thousands of parakeets; in Sumatra a female orang-utan and her daughter face life in a forest under threat; while in Tanzania local people use satellites to replant a forest, securing the future for a family of chimpanzees. This is our home as we’ve never seen it before.

Changing the Script

   2020    History
The written word is so important in everyday life that there can be few more radical acts than forcing an entire nation to learn a new script. Yet that is what happened in Turkey in 1928 when Mustafa Kemal decreed that the Arabic script would be replaced by the letters of the Latin alphabet. Communication with computers using human language is usually made with Latin letters. This is how most Chinese people interact with their computers and smart phones, using a Latin-based phonetic script called Pinyin. As a result, even highly educated Chinese are losing the ability to write using Chinese characters. Could what is happening in China be the future of writing everywhere?
