  • Green Chemistry

    There are more than 80,000 synthetic chemicals in commerce today. Green Chemistry, the science of creating less toxic or entirely non-toxic chemicals to replace those harmful to humans and the environment, is making a small but important dent in this multi-billion dollar industry. In this audio segment from PRI's The World Science Podcast we hear from Elizabeth Grossman, author of Chasing Molecules about how scientists are changing the raw materials used by chemists, and why Green Chemistry is an attractive alternative for industries.

  • Bhopal’s Unlikely Legacy

    When news about the gas leak in Bhopal, India reached the rest of the world, it alerted people to the potential dangers from industrial plants in their own communities. In this audio segment from PRI's The World Science Podcast we learn that in the United States, the tragedy resulted in major new legislation to protect the American public from toxic substances, while in India, unfortunately, changes have been slower in coming.

  • World Science Podcast | China’s Innovative Past

    For more than a thousand years, China led the world in innovation. And then, about 500 years ago, it lost its creative edge to the West. As China’s Communist Party prepares to celebrate 60 years in power, China hopes to regain its advantage. This audio segment from PRI's The World Science Podcast explores the roots of China's creative past, and the geographical, political, and economic factors that might have contributed to its apparent demise.

  • Saving the World’s Potatoes

    There are 5,000 varieties of native potatoes grown by farmers in the South American Andes Mountains, many so diverse we might not recognize them as potatoes! In this audio segment from PRI's The World Science Podcast, we learn about some of these extraordinary specimens and hear about the mission to protect them, as well as the farmers who grow them.

  • Creativity in Chinese Education

    This audio segment from PRI's The World Science Podcast takes us into the classroom in China, where a culture of rote memorization has long been favored over independent thinking. As a result, Chinese schools are not graduating innovators, including scientists and engineers, at a pace the government would like. A new kind of school in Beijing is challenging the traditional approach to learning, and China’s Ministry of Education is also trying to move public schools towards a more liberal education. But how successful will the effort be, given that critical thinking is in direct conflict with the ideals of the Communist Party?

  • Naming Uranus and Neptune, in Hebrew

    In this audio segment from PRI's The World Science Podcast we learn that the ancient Hebrews gave five planets, and Earth, Hebrew names. As Uranus and Neptune had not then been discovered, Israelis later adopted the Western names for these planets, but The Hebrew Language Academy, a government funded institution that coins new Hebrew terms, wants to change this and is asking the public to decide on new Hebrew names for the two planets. This podcast explores the inspirations behind some of the 2000 suggestions, and reveals the finalists to be voted on this year.
