Stem Cells: Seeds of Hope?
Do stem cells hold the best hope for curing debilitating diseases like Tay-Sachs and diabetes? Or do the ethical questions surrounding the use of these exceptional little cells stand in the way of any potential they might have? In this video segment Dr. Evan Snyder, professor of neurology at Harvard Medical School, explains the basics of stem cell technology and outlines the ethical debate regarding its use. Closed captioning included. Run time 07:00.

Flu Attack! How A Virus Invades Your Body
When you get the flu, viruses turn your cells into tiny factories that help spread the disease. In this animation, NPR's Robert Krulwich and medical animator and medical animator David Bolinsky explain how a flu virus can trick a single cell into making a million more viruses. (MHS gr 7 1C)
Parkinson's Disease Research
This video looks at current research into treatments for Parkinson's Disease, including genetically modified viruses and stem cell treatments. This video interview explains the hope and challenges that have been encountered. 4:35 min.
Cell Phone Bacteria
This spot done by Nicole Brady of KOB-TV in Albuquerque shows how many Germs can accumulate on your Cell Phone. Short news clip reminds people the health issues associated with unsanitary phones. Grades 5-12. 3:01 min.
Immune Cells in Action
In this video segment from The Secret of Life, you'll look through a microscope at a virus attacking a cell. Viruses continue to replicate until they break apart the host cell and start spreading throughout the body, destroying healthy cells along the way. You'll learn how the immune system overpowers a virus with white blood cells and creates the antibodies that kill the same types of viruses quickly if they return. Closed captioning included. Run time 01:40.
This visualization adapted from the University of Massachusetts Medical School represents the process by which a dengue virus releases its genetic contents inside a host cell, allowing viral replication. The key players are proteins found on the viral surface called envelope proteins, which change their structure when the virus is endocytosed, or taken inside the cell. This structural change enables the viral membrane to fuse with the endosomal membrane, and the virus' RNA to enter the cytoplasm

Oscar Wilde Bio 7
A&E Biography. His prison time is spent in a 10 by 13 foot cell at Redding jail. There was no toilet, writing materials, and only the Bible to read. Special arrangements were made for paper and pen in which Wilde wrote a letter to Bosie. On May 18, 1897, he’s released from prison. He meets up with Bosie. Constance gets mad, takes his allowance away and forbids him from seeing his children. Four months later she dies and the las
'The 'kidneys are a bean shaped, fist size organ whose task is to filter blood and remove the waste.' This is a quote from the video. The information is related in a 'dry' way but the content is usable. The instructor appears to be using slideshow.
Influenza virus explained - how humans catch flu
This is a 2 minute animated video about influenza and how humans get the flu. It takes you on the journey of an influenza virus, how it is contracted, attack attacks, and ultimately departs from the cell of an infected person.
(MHS gr7 1c)
Video clip shows a microscopic blood vessel only one cell layer thick, so that individual blood cells must move through single file. Grades 5-12. 13 seconds.
The Function of the Liver
Did you know that the liver is the largest organ in the human body? Learn more in this computer-animated video (04:02) that describes where the liver is in the body and its function. This video has English captions at the bottom of the screen. This may be good for big classrooms where sound may not travel well.
Note: There is a little static as the narrator appears to be too close to the microphone while speaking. Also, in the summary the word 'learned' is spelled incorrec
This video segment from Design Squad features the work of Howard Pryor, a tissue engineer and doctor at Massachusetts General Hospital. Dr. Pryor demonstrates a device he is working on to replace diseased livers. He explains the challenges of artificially engineering a human organ, including getting blood to flow through a device for processing just as it would through a liver. He also details the design process that helps all engineers not only analyze a problem and develop a solution, but also
The Sense of Sight
The eye is a complex organ composed of many small parts, each vital to normal vision. The ability to see clearly depends on how well these parts work together.
What's a Nano?
Ebony and her cousin Jasmine take you on a trip to the museum to discover what a nano is. Ebony knows that nanotechnology is helping make electronics, like her cell phone, smaller and smaller. But that's about all they knew about nanotechnology until they caught the Amazing Nano Brothers Juggling Show at the Museum of Science in Boston. The jugglers introduce the girls to the nanoworld. They learned from the Nano Brothers that a nanometer is one billionth of a meter. The girls then go o
How Changes in Earth's Magnetic Field and Ionosphere Affect Us - Part 4
Part 4 in a discussion on How do changes in Earth's magnetic field and ionosphere affect us? Anya Strømme – EISCAT/SRI International. She’s working with very high power radar to study the aurora borealis which are better observed at higher latitudes. She’s studying particles coming into the atmosphere, heating it, generating currents—this is where our satellites fly…this impacts tv reception, GPS, cell phones in a much more dramatic way than we can imagine. Run time 03:16.
How the Body Works : Inside the Heart
Suitable for older middle school students and high school students. A quote from the video: "The heart is a muscular pumping organ which beats nonstop to circulate blood around the body. It functions as two halves, each consisting of a holding chamber, or atrium, and a pumping center, or ventricle."
The Power House of the Cell
Mitochondria play host to one of the most important processes in your
body: cellular respiration. Taking in glucose and oxygen, mitochondria
produce energy, which they capture and package as energy-rich molecules of ATP. This video describes the structure and functions that give mitochondria their nickname: the powerhouses of the cell. Closed captioning included. Run time 05:47.
