Nucleus, Cytoplasm, Membrane
What constitutes a cell? More than any other structures, it's the nucleus, cytoplasm, and membrane. Explore the form and function of these three critical cell parts in this video segment adapted from Carolina Biological Supply's An Introduction to the Living Cell. Closed captioning included. Run time 03:47.
Organelles in the Cytoplasm
For the longest time, scientists couldn't imagine how simple cells managed to perform so many amazing tasks in living organisms. It turns out that cells aren't simple at all. Much like complex organisms with organs that perform specific tasks, cells have many organelles that keep them functioning properly. Explore some of a cell's most important structures in this video segment from An Introduction to the Living Cell. Closed captioning included. Run time 06:06.
Corn Genetics - How Stuff Works
This video studies the genetic diversity of corn. With over 50,000 genes, a cell from a corn plant contains twice as much genetic information as a cell from a human being. Overview of the importance of corn in our lives and how scientists are looking to the future. Grades 5-12. 2:34 min.
This is a video accompanied by text (click on the text icon to see it) "A genetic mutation is any change in a cell's DNA, the chemical that carries all of the genetic information in a cell. Would you ever think that a beneficial genetic mutation that occurred thousands of years ago could cause a serious illness today?
In parts of Africa, the Mediterranean, South America, and the Middle East, malaria epidemics killed large numbers of people many centuries ago. Children who inherited one cop
President Obama On Stem Cell Research
President Obama signed an order reversing the strict limits on human embryonic stem cell research. This is the video of his speech. President Obama addresses the controversy of scientific research on stem cells, but stresses the advances that can be made by science. Grades 9-12. 11:25 min.
What Is Stem Cell Research?
Stem cell research uses stem cells to find new avenues, and some
research is basic, while other research involves applying stem cells to
the field of medicine. Find out how stem cell research is being used for bone marrow transplants in this clip.
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.
Introduction to Cancer
Sal Khan offers an introduction to cancer and how it is the by-product of broken DNA replication. The instructor uses drawings to illustrate mutations, apoptosis, mitosis, cell replication, replication of cells. (12:36)
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
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.

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.
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.
