Glowing Life in an Underwater World
Some 80 to 90 percent of undersea creatures make light -- and we know very little about how or why. Bioluminescence expert Edith Widder explores this glowing, sparkling, luminous world, sharing glorious images and insight into the unseen depths (and brights) of the ocean. Edith Widder combines her expertise in research and technological innovation with a commitment to stopping and reversing the degradation of our marine environment. Run time 17:20.
Conserving the Canopy

A unique ecosystem of plants, birds and monkeys thrives in the treetops of the rainforest. Nalini Nadkarni explores these canopy worlds -- and shares her findings with the world below, through dance, art and bold partnerships. Run time 16:27.
Kilauea Volcano Erupts - Dramatic Video
This video is suitable for older elementary, middle school, and high school students. Kilauea is the youngest and southeastern most volcano on the Big Island of Hawaii. Topographically Kilauea appears as only a bulge on the southeastern flank of Mauna Loa, and so for many years Kilauea was thought to be a mere satellite of its giant neighbor, not a separate volcano. However, research over the past few decades shows clearly that Kilauea has its own magma-plumbing system, extending to the surface
How do changes in Earth's magnetic field and ionosphere affect us? - Part 2
Part 2 in a discussion on How do changes in Earth's magnetic field and ionosphere affect us? Gang Lu – National Center for Atmosphere Research. Talks about her data analysis of radar and satellite data. Talks about the continuing exploration of all that is to be investigated in exploring the fine particle changes in the aurora. Run time 03:38.
Living Band-Aid Beats Like a Heart
Video shows current research in heart tissue structure and repair. Jordan Lancaster and Steven Goldman, researchers from the Southern Arizona Veterans Administration and the University of Arizona, put rat heart cells on a piece of synthetic mesh and within a few days, it started beating. The hope is that down the road the patch of cells could be used to treat damaged hearts.

Controlling the Brain with Light - Optigenetics
Karl Deisseroth is pioneering bold new treatments for depression and other psychiatric diseases. By sending pulses of light into the brain, Deisseroth can control neural activity with remarkable precision. In this short talk, Deisseroth gives an overview of his Stanford University lab's groundbreaking research in "optogenetics".

The Effects of Hormones and the Environment on Brain Development
This module presents some startling and significant findings relating to the effects of sex hormones on brain development. Beginning with in utero photography and then visiting an animal laboratory, this module shows how Dr. Marian Diamond’s ground-breaking research has revealed structural differences in the brains of men and women, as well as factors influe
Pearl Harbor-December 7, 1941
Because the clouds have cleared on Sunday morning - December 7, 1941 - every pilot has an unobstructed view as hundreds of Japanese airplanes approach Pearl Harbor, Hawaii.
With strike force orders from the high command, and detailed information supplied by Takeo Yoshikawa (a Japanese spy at Pearl), pilots know their individual targets. In 110 minutes, the U.S. Pacific Fleet will be horrendously crippled.
At 7:58 a.m., Lt. Commander Logan Ramsey dispatches an urgent
Can We Believe Our Eyes
Why is it that students can graduate from MIT and Harvard, yet not know how to solve a simple third-grade problem in science: lighting a light bulb with a battery and wire? Beginning with this startling fact, this program systematically explores many of the assumptions that we hold about learning to show that education is based on a series of myths. Through the example o
Having determined the complete DNA nucleotide sequence of humans and several other organisms, today’s research has shifted to identifying genes and determining their functions. This session reviews the techniques used in BLAST searches, microarray experiments, and other genomics tools.
This video segment adapted from A Science Odyssey tells how two
scientists, Howard Florey and Ernst Chain, used the research findings
of Alexander Fleming to turn a natural compound, penicillin, into an
effective treatment for bacterial infections. Their tests in mice and
later in human patients demonstrated penicillin's ability to cure such
infections. After U.S. drug companies figured out how to mass-produce penicillin, its reputation as a "miracle drug" was e
Inventions of War - the Radar
Which country developed the world's first radar system and when did
they do it? And how did radar research later lead to the invention of a
device found in most modern kitchens? Run time 3:14
Toxic: Garbage Island
For years we've been reading about a patch of garbage the size of Texas floating in the middle of the Pacific Ocean, ingeniously dubbed the Great Pacific Garbage Patch. Basically, any trash that gets dumped in the water rides the currents to this one spot and joins an ever-increasing flotilla of garbage. For all the breathless accounts of the mess and its impact on the area's sealife, however, no one seemed to have a picture of the buildup.
In order to sate our own curiosit
Re-Wiring the Brain
Neuroscientist Michael Merzenich lectures on the secrets of the brain's ability to actively re-wire itself. He discusses his research into ways to harness the brain's plasticity to enhance our skills and recover lost function. The ability of the brain to grow and change as we develop is a complex process that progresses in a predictable way.
