From the Heart
This video segment describes how the chambers of the heart contract and relax in synchrony to push blood through the pulmonary and systemic loops of the circulatory system. You'll see how the heart pumps oxygen-depleted blood to the lungs, where red blood cells acquire oxygen before travelling back to the heart and then on to the rest of the body. The video is nice illustration of how the circulatory and respiratory systems work together to carry in oxygen and remove waste. Closed captioning i

Plant Cell Motility and Laser Microsurgery of Cytoplasmic Strands
Plant cells are shaped by rigid cell walls. Osmotic forces press the plasma membrane tightly against these walls. The walls can be removed with enzymes. The remaining structures, the protoplasts, are now bordered by the plasma membrane. Since the shaping force of the wall is missing, isolated plant protoplasts are usually perfectly spherical in shape as a result of non-directional osmotic forces. Run time 04:19
Microanatomy of the Lungs
Presented here is the microanatomy of the lungs and its components. The video shows an animated lung while a narrator explains the various parts labeled on the screen. "Alveolar sacs are the terminal portions of the breathing tube system. Composed of up to thirty tiny air pouches, or alveoli, they provide a lung a total surface area of about 850 square feet for the exchange of gases. Terminal bronchioles carry air to and from alveolar sacs. Cells lining bronchiole walls bear cilia---minute ha

An overview of the main issues on research on computer supported inquiry learning is provided including issues such as assessing learning effects of computer support, gaming
C++ Console Lesson 19: Function Templates
More at http://xoax.net
This C++ video tutorial shows how to create and call function templates. Function templates are special functions that can operate with generic types. This allows us to create a function template whose functionality can be adapted to more than one type or class without repeating the entire code for each type.
Gulf Oil Spill Effects On Wildlife
'New reports are surfacing every day about the immediate impacts of the Deepwater Horizon oil spill on Gulf Coast wildlife, especially as the oil reaches the sensitive marshlands along the coast. But how will these communities be affected over time? Scientists currently know very little about how long it takes for the hydrocarbons and heavy metals in crude oil to work their way through marine food webs. To address this issue, California Academy of Sciences researcher Peter Roopnarine is working
