  • VIDEO: Tour of the Exploratorium in San Francisco
    Monday, July 9, 2012

    In classrooms kids can learn about the basics of science and watch cool experiments. But, where can they learn to experiment on their own? The Exploratorium in San Francisco, California is an interactive museum where kids and adults can try experiments for themselves and learn about the world around them. »

  • VIDEO: Plants for medicine with ethnobotanist Michael Balick
    April 29, 2013

    Traditional cultures in tropical, subtropical, and desert environments have long understood and used plants for the treatment of illness and to promote well-being. Michael Balick studies the relationship between plants and people as an ethnobotanist for The New York Botanical Garden in the Bronx. His work has taken him all over the world. Just recently Balick was on a remote Pacific island in the republic of Vanuatu where he was working with indigenous people, talking to them about health care and their interest in documenting the medicinal knowledge of their elders. »

  • VIDEO: Dark matter in direct, indirect and collider experiments
    February 20, 2013

    Neil Weiner of New York University explains how the search for dark matter is going, and why he is confident we will find it, or at least know what we are looking for, in the near future. The properties of dark matter may be influenced by new forces that effect how dark matter interacts with itself and with ordinary matter. Such forces can lead to new signals in direct or indirect dark matter searches, and might explain some of the anomalous results already reported by such searches. Interacting dark matter may also explain the mysterious properties of dwarf galaxies. »

  • VIDEO: Making the molecular movie
    February 20, 2013

    There is a camera that has both sufficient shutter speed and sensitivity to capture atomic movies of structural dynamics. The machine built at the University of Toronto was the first to make "Molecular Movies". It uses an extremely "bright" source of electrons to ping off the atoms and report on their motions. This advance has opened up a new kind of microscope to reveal the atomic world to us in motion. R. J. Dwayne Miller, University of Hamburg, shows us several of these movies. »

  • VIDEO: Robert Kirshner and the beauty of our accelerating universe
    February 19, 2013

    Astrophysicst and author of the book The Extravagant Universe: Exploding Stars, Dark Energy, and the Accelerating Cosmos takes us on a thrill ride through a universe dominated by dark energy but also containing several forms of dark matter. "We live in an extravagant universe with a surprising number of essential ingredients: the real universe we measure is not the simplest one we could imagine," says Kirshner.

  • VIDEO: The history of Antarctic whaling
    February 19, 2013

    D. Graham Burnett, Princeton University, discusses his recently published book The Sounding of Whales which examines the history of cetology in the 20th century. His talk connects the history of Antarctic whaling with the scientific knowledge gained from this industry, much of which hunted blue whales nearly to extinction. Learn more about this session »

  • VIDEO: Cynthia Kenyon on aging and biology
    February 19, 2013

    Discovery that a single-gene mutation could double the lifespan of the worm C. elegans sparked an intensive study of the molecular biology of aging. Kenyon was apart of the team that made this discovery. Her findings have since led to the discovery that an evolutionarily conserved hormone signaling system controls aging in other organisms as well, including mammals. She highlights her work and what the future holds as we seek to unlock the secrets of aging. Learn more abou this speaker »

  • VIDEO: Rachel Carson and 50 years of 'Silent Spring'
    February 18, 2013

    Rachel Carson brilliantly bridged the cultures of science and the humanities, showing how human-dominated and natural systems are intertwined. Through Carson's writings, Sharon Kingsland, Johns Hopkins University, reminds us of Carson's gift for making people care about their environment and how scientists can still learn from her today.

  • VIDEO: Stroke recovery protocal helps patients regain speech
    February 17, 2013

    Recent research has shown that melodic intonation therapy enhances speech output in non-fluent aphasic patients. Improvements have occurred in the successful production of words and phrases as well as spontaneous speech output. Sheila Blumstein , Brown University, developed a protocol adapting the melodic intonation procedure to examine whether modeling the speech output of the examiner results in an improvement in the production of the sounds of language. »
