Eric R. Kandel, HHMI Investigator, examines whether the brain's two major memory systems, implicit and explicit, have any common features. Implicit and explicit memory both have a short-term component lasting minutes, such as remembering the telephone number you just looked up, and a long-term component that lasts days, weeks, or a lifetime, such as remembering your mother's birthday. Short-term memory is mediated by modifications of existing proteins, leading to temporary changes in the strength of communication between nerve cells.

A very well built documentary about cannabis and drug prohibition. Does the drug prohibition work? Have a look and think for yourself.

An inspiring documentary on the Cradle to Cradle design concept of the chemist Michael Braungart and the architect William McDonough. Winner of the Silver Dragon at the Beijing International Science Film Festival 2006. OUTLINE: Man is the only creature that produces landfills. Natural resources are being depleted on a rapid scale while production and consumption are rising in na­tions like China and India. The waste production world wide is enormous and if we do not do anything we will soon have turned all our resources into one big messy landfill. But there is hope. The German chemist, Michael Braungart, and the American designer-architect William McDonough are fundamentally changing the way we produce and build.

Communication is a crucial part of everyone's life, yet millions of Americans suffer from communication disorders. In fact, stuttering affects about 1 percent of the U. S. population. Dr. Dennis Drayna, of the National Institute on Deafness and Other Communication Disorders, explains how genes affect the ability to communicate and discusses his work with stuttering and disorders of pitch recognition, also known as 'tone deafness.'

G. Edward Griffin's 1974 book World Without Cancer is as poignant today as the day it was written, and in some circles, just as controversial. That's because Griffin tells the story of a powerful substance that, despite its potential to aid in the fight against cancer, few cancer sufferers will ever know about, and that their doctors certainly will not offer them. That substance is vitamin B-17, also called Laetrile, and it is a naturally-occurring substance that has been banned for use in the control of cancer in the United States.

Eric R. Kandel, Howard Hughes Medical Institute investigator, probes into the mind to demonstrate how it is much more complex than just a series of processes carried out by the brain. The brain produces our every emotional, intellectual and athletic act. It allows us to acquire new facts and skills, and to remember them for as long as a lifetime. Memory exists in two major forms, each located in different brain regions. Explicit memory is for people, places, and objects. In contrast, implicit memory serves perceptual and motor skills.

Water, The Great Mystery is all about it: the most amazing yet least studied material in the world.

As of its release in early 2007, Planet Earth is quite simply the greatest nature/wildlife series ever produced.

Earthlings is an eye-opening documentary about humanities many mischiefs (animal cruelty) on planet earth. Sometimes the recordings of a few hidden cameras is all that is needed to say a thousand words, and in this case also experience a thousand emotions. Each and every one of us are earthlings. We share this world with millions of other species, and yet we tend to abuse and damage them mercilessly, not realizing that we are completely dependent on other earthlings.

How have human hands molded the earths biomes? Dr. Erle Ellis, associate professor of geography and environmental systems, unveils the way humans are changing the planet with regards to land use in the biosphere. This University of Maryland at Baltimore County video is hosted by Karin Readel, lecturer in environmental science.
