Accessible subtitles - various rules

Generally, a transcript CAN be used as subtitles. However, if - and you should! - you want accessible subtitles, you need to tweak the segments a bit manually. However, this can quickly become confusing when working on bigger projects. In this video, we will show you how to master this challenge q

How Cancer Cells Grow and Divide

Discover the role of oncogenes in uncontrolled cancerous growth and depicts the journey of cancer cells from where they originate, into the circulatory system, and then on to other parts of the body. This video is available in both English and Spanish audio, along with corresponding closed captions.

Human Genome Project

In this video segment from NOVA: "Cracking the Code of Life," Eric Lander of MIT's Whitehead Institute explains the effort to decode the human genome—from motivation to process to importance—and explains what a genome map can and cannot yet do for science. This video is available in both English and

How DNA Replicates

This narrated animation from Interactive NOVA: "The Secret of Life" shows the double helix structure of DNA and how the molecule replicates. The segment illustrates how DNA "unzips" to form templates for the new strands and how complementary nucleotides bind together like the rungs of a ladder. This

Total Solar Eclipse Animation

Solar eclipses result from the alignment of the Sun, Moon, and Earth. Total solar eclipses — in which the Sun is completely blocked by the Moon — are a spectacular and rare sight to witness. In this animation adapted from NOVA, see why solar eclipses occur and observe a simulated total eclipse. This

Career Profile: Research Assistant Sandra Bustamante

Hear how a research assistant got her start in biotechnology — Sandra fell in love with science during her certificate program in Boston, Massachusetts. The video details not only Sandra's cutting-edge research work — using nanotechnology, rather than needles, to deliver vaccines — but also the qual

Raising an Obelisk: An Engineering Puzzle

In this NOVA video, two teams test out two theories put forth by archaeologists to explain how ancient Egyptians might have raised massive obelisks to stable, upright positions. While only one plan works in practice, both attempts demonstrate that difficult challenges require careful planning. This

Energy Flow in the Coral Reef Ecosystem

Learn how energy from sunlight is transferred through the inhabitants of the coral reef ecosystem. Photosynthesizing plants and algae convert light energy into chemical energy, which then gets passed through the food web to plant eaters, flesh eaters, and ultimately to scavengers and decomposers. Vi

The Powerhouse of the Cell

Mitochondria play host to one of the most important processes in your body, called 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

Fever!

Have you ever wondered why overheating on a hot day and getting a fever when you're sick feel so different? Both involve an increase in your body's temperature. However, in one case your brain and body do everything they can to cool you off, while in the other they push the temperature inside your b

Earth System: El Nino's Influence on Hurricane Formation

Warm water fuels the tropical storms that ultimately form hurricanes. In this video segment adapted from NASA's Goddard Space Flight Center, learn how El Niño events—climatic anomalies that occur periodically in the Pacific Ocean—alter the course of atmospheric circulation and lessen hurricane forma
