This is the updated Amoeba Sisters human organ systems video, which provides a brief introduction to each of the 11 human organ systems including the circulatory, digestive, endocrine, excretory, integumentary, lymphatic/immune, muscular, nervous, reproductive, respiratory, and skeletal systems.

Sulston worked alone, in silence, hunched over a microscope for eight hours a day. By studying and drawing worms of various ages, he figured out the ancestor and descendants of each of their cells. It was a monumental piece of science. Sulston mapped the complete history of an individual, the comprehensive family tree of a single body. "We had the entire story of the worm's cells from fertilized egg to adult," he later said, upon accepting the Nobel Prize for his work.

You may have heard of stem cells before, but there is a lot of mystery about what they actually … do. Why is this such a promising new field?

nique mutations used to trace history back to its origins in the embryo Date: June 29, 2014

LifeMap Discovery® is a compendium of embryonic development for stem cell research and regenerative medicine, constructed by integrating extensive molecular, cellular, anatomical and medical data curated from scientific literature and high-throughput data sources.

There's a lot we don't know about how and when dogs were first domesticated. But we do know that the process made dogs very different from their wild cousins, in some unexpected ways.

Life sciences focus on all things living, exploring the patterns, processes and relationships of organisms. The goal of life sciences is to demonstrate how unifying principles can help us to make sense of the natural world and solve problems in the world we live in. High school life sciences extend student knowledge of topics such as organisms, ecosystems, heredity and evolution, integrating a long history of scientific research from multiple fields. In high school, students will build on their conceptual understanding of life sciences by investigating and witnessing the relationships among structure and function, matter and energy, ecosystems and natural selection. Students should be able to effectively communicate facts and findings, as supported in the science literacy skills covered in the Common Core State Standards.

The announcement comes about a week after the state's first case of measles of the year was confirmed. Cook County health officials would only identify the person with measles as a suburban resident who is older than 18. At the time, officials listed three places where others might have come into contact with the measles patient in mid-January - including two in Palatine.

This two-minute video provides brief background on the use of zebrafish as a model in studying animal development, before showing a time-lapse sequence of a fertilized zebrafish egg developing into a larva.  The video includes some annotations that help orient the viewer during the time-lapse sequence.  Teachers might want to mute the narration beginning at 0:42 min to avoid giving students too much information.  This phenomenon could stimulate the following driving questions: How does the zebrafish develop from one cell to the many cells that make up the larva? How do the zebrafish cells divide? How are the developing zebrafish cells similar and different from each other? If all cells in the zebrafish develop from the same original cell, then how do some cells develop differently than others? How are cell division and growth related?
