Host Emily Graslie meets with James Holstein, the Collection Manager of Meteoritics and Physical Geology, to discuss deadly rocks. Some minerals contain harmful elements that can cause damage through repeated exposure in unregulated environments. Part of "The Brain Scoop" series.

I think what your eyesight does is confirm other senses, says James Robertshaw, a world champion kite flyer and for two years personal assistant to Rory Heap. Heap has been blind from birth, but with Robertshaw's assistance pursues his ambition for kite flying--particularly of complicated figure eight patterns. Using all of his senses except for sight, Heap learns how to fly a kite with the same dexterity that Robertshaw uses to guide him through busy city streets.
Adabot meets James Prescott Joule and learns all about the joule, a unit which measures work. Part of the "Circuit Playground" series.
Political scientist James Fowler makes the connection between smiling profile pictures on Facebook and human evolution.
Photographers and scientists try to explain their fascination with volcanoes and earthquakes. Focuses not on the geological causes, but on how and why these phenomena are photographed and studied. Uses actual footage and closeups for impact. James Earl Jones narrates.
Discover how the James Webb Space Telescope will help scientists studying the formation of stars. The telescope will provide infrared observations and give astronomers an unprecedented view of stellar birth. Computer models show how a giant cloud of gas and dust collapses to form stars and planets.
This program from the acclaimed PBS Nature series, "Forces of the Wild," focuses on the seasonal cycle of nature, beginning with spring's return of life to the planet. Uses natural history footage, computer animation, and time-lapse sequences to explain universal concepts. Narrated by James Earl Jones.
This episode celebrates the 229th birthday of John James Audubon. Host Emily Graslie spends time discussing "The Birds of America" written by Audubon. Part of "The Brain Scoop" series.
This program from the acclaimed PBS Nature series, "Forces of the Wild," shows how man risks everything by building on earthquake fault lines, farming the slopes of volcanoes, polluting the air and warming the Earth. Like children playing with matches, we have no idea of the consequences of what we are doing. Narrated by James Earl Jones.
This program from the acclaimed PBS Nature series, "Forces of the Wild," focuses on how the movements of the sun and moon create powerful rhythms which influence all living things on Earth: tides rise and fall, seasons change, creatures breed or migrate, and humans plant crops and celebrate holidays. Narrated by James Earl Jones.
This program from the acclaimed PBS Nature series, "Forces of the Wild," looks at man's constant attempt to adapt the Earth to his own needs without concern of the consequences. Earth is a self-regulating organism full of forces impossible to control. Water is one force, creating life where there is none and destroying life when it can't be tamed. Narrated by James Earl Jones.
Nano expert Jameson Wetmore from Arizona State University offers tips for managing the potential risks associated with nanotechnology. Part of the “Ask a Scientist” series.
What determines how many species live in a given place? Or how many individuals of the species can live somewhere? The research that provided answers to these questions was set in motion by the key experiments of ecologists Robert Paine and James Estes. Their research demonstrates just how fundamental keystone species and trophic cascades are in understanding ecology.
This University of Miami residence hall may look typical, but students in one of the apartments are participating in research involving one of the planet’s most precious commodities--water. With support from the National Science Foundation (NSF), environmental engineer James Englehardt and his team created a net zero water system, which serves most of the residents’ daily needs, including dish washing, showering and laundry. All of the water is treated just outside the building, and reused in a sustainable loop. Part of the National Science Foundation Series “Science Nation.”
James Woodenlegs first learned to communicate using Plains Indians Sign Language from his family, growing up on the Northern Cheyenne Reservation in Montana. Also known as “hand talk,” the language has been used by both deaf and hearing Indians from Canada to the Gulf of Mexico for at least 200 years, possibly much longer. Woodenlegs is working with sign language scholars Jeffrey Davis and Melanie McKay-Cody to document and preserve hand talk, one of thousands of the world’s endangered languages.
This album of eight computer-animated video segments looks at the particle approach to studying light by exploring the antithesis of the wave model. Presents black-body radiation, Planck's constant, the photoelectric effect, and the work of James Clerk Maxwell as forerunners to Einstein's concept of photon frequency. Shows examples of a slope-intercept graph and a revised double-slit experiment using light-sensitive paper segue to an illustration of the Compton effect, establishing that light consists of a stream of particles. De Broglie's contributions introduce wave-particle duality, which some might consider an inadequate solution, although it represents the best that current science can do.
James Watson and Francis Crick collected and interpreted key evidence to determine that DNA molecules take the shape of a twisted ladder—a double helix. The film presents the challenges, false starts, and eventual success of their bold chase. Watson relates what those early days in the Cavendish Laboratory were like, including his friendship with Crick and their shared ambition and passion. Rarely seen archival footage is combined with interviews with some of today’s leading scientists to bring this landmark discovery and all of its implications to life.
In the early 1950s, American biologist James Watson and British physicist Francis Crick came up with their famous model of the DNA double helix. The structure of DNA, as represented in Watson and Crick's model, is a double-stranded helix. The sugar-phosphate backbones of the DNA strands make up the outside of the helix, while the nitrogenous bases are found on the inside and form hydrogen-bonded pairs that hold the DNA strands together. Other topics covered include DNA replication, RNA transcription, and RNA translation. Part of the "Biology" series.
Proteins are the workhorses of cells. With support from the National Science Foundation, University of Arkansas biochemist James Hinton has been researching their structure and function for decades. Back in the 1990’s, he had a vision to study these huge protein structures in 3D and now, in cooperation with a company called Virtalis, his vision has become a reality. The new system allows researchers to enlarge the visual of a protein to room-size, so they can examine it from all angles, to better understand its structure and function. The new 3D visuals are also helping Hinton realize his other vision to better engage students in his discoveries and science in general.
