Displaced Jews-Effects on a family
This clip, from a BBC miniseries, focuses on Jews who escaped the growing threat of Nazism. Living in other countries, like Britain, many later told their children: "The only thing that matters in life is what's inside of you because nobody can take it away." (29:09)
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
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".

How The Body Works: The Regions Of The Brain
The brain has three major functional and anatomical parts--the forebrain, midbrain and hindbrain. The forebrain consists of the cerebral hemispheres, thalami, hypothalamus and limbic system. The top inch of the brain stem is the midbrain. The hindbrain includes the cerebellum, the pons and the medulla. Video uses animated diagrams. Grades 9-12. 1:16 min.
How the Body Works : Movement and the Cerebellum
A brief video on the cerebellum. The cerebellum, part of the hindbrain, is concerned with the regulation of coordination and balance. It is an oval-shaped structure with a central furrow, which is flanked on either side by a bulbous lobe. Run time (1:36)
How Brains Learn to See
Pawan Sinha details his groundbreaking research into how the brain's visual system develops. Sinha and his team provide free vision-restoring treatment to children born blind, and then study how their brains learn to interpret visual data. The work offers insights into neuroscience, engineering and even autism.
How the Body Works : The Auditory Pathways in the Brain
The auditory center, in the brain, shown above in red, is concerned with hearing. Although shown here on the outer surface of the brain, most of this area lies within the temporal lobes and is found within the surface of the cerebral cortex on both sides of the brain.
The Ventricles of the Brain
The ventricles of the brain are four cavities which are filled with cerebrospinal fluid. Two large lateral ventricles are in the cerebrum, the third ventricle lies between the two thalami and the fourth between the cerebellum and the brain stem. (00:17)

Lily Pad Escape
In this video segment from Cyberchase, the CyberSquad is trying to escape from a desert island by crossing a large body of water. They find a special lily pad that was left for them by the Red Warrior. When the lily pad is put in water it doubles and the number of lily pads keeps on doubling. The CyberSquad tries to use this doubling effect to help them create a lily pad bridge to cross the water and escape. Run time 02:49.
