Explore an unfamiliar universe in these videos created at the Microscope Imaging Station. This and other explorations from Living Systems on exhibit through the end of March 2010 in the Ambient Biology installation, located in the Webcast Studio.

DETAILS
• Zebrafish embryo: Cell division during the first 2.5 hours of fish embryo development. (The eggshell has been removed.)
• Cells that resemble neurons: Neuron-like cells, grown from mouse embryonic stem cells.
• Fruit fly pupae, just before hatching. Elapsed time about 5 days.
• Frog eggs: Eggs of the African Clawed Frog during development, filmed over many days.
• Blood cell lysis: Red blood cells from sheep lyse (break open) and fade from view. Elapsed time about 2.5 minutes.
• Crawling Amoeba: A microscopic amoeba crawls across a slide. Elapsed time about 5 minutes.
• Mouse embryonic stem cells and HeLa cells: Mouse embryonic stem cells and HeLa cells (cancer cells) move, grow, and divide in culture.
• Crawling Planaria: Tiny flatworms called planaria, move away from light using cilia (tiny hair-like structures) and mucus.
• Sea slug neuron: The tip of a nerve cell (called a growth cone) from a sea slug moves dynamically in response to various stimuli. (Movie generously provided by the Smith lab at Stanford University.)
• Sea urchin embryos dividing: A field of sea urchin eggs that were fertilized at the same time divide in near-synchrony. Elapsed time 4 hours.
• Volvox globator: The green algae Volvox globator exists as a spherical colony of individual cells. Each cell has two whiplike appendages called flagella that propel the entire colony through water. Elapsed time about 1 minute.
