They have been developed specifically to find a cure for heart hypertrophy - a form of heart disease that can lead to sudden death. Made from stem cells, the tiny hearts are just 1mm in diameter and contract at around 30 beats per minute. Although healthy to begin with, the scientists are using chemicals to simulate the physiological conditions that will make them become hypertrophic - enlarged, due to abnormal growth of the cells that make up the heart (cardiomyocytes). Once diseased, the hearts are then treated with newly developed medications to see if they can prevent the damage from occurring. Professor Nikolai Zhelev, who is leading this research, explains: "Although human hearts have been grown in labs before, this is the first time it has ever been possible to induce disease in them. Professor Bown explains:
The Case Files Online Exhibit Homepage | The Franklin Institute's Resources for Science Learning This presentation of The Franklin Institute's Case Files highlights individuals from the history of science and technology. It is one of many Resources for Science Learning. Each thematic group of Files presented at left begins with commentary from a distinguished historian of the discipline. About The Case Files The Franklin Institute's Case Files are a unique repository in the history of science and exist as the documentary record of The Franklin Awards program which, since 1824, has recognized outstanding scientific achievement, across all scientific disciplines. Within each Case File is a story, waiting to be told, of scientific enterprise and social circumstances. Likewise, the Institute's annual Awards Week program is a vibrant celebration of scientific enterprise and the scientists at its forefront. About the Committee onScience and the Arts The Franklin Institute's Committee on Science and the Arts (CSA) oversees the Awards program and maintains the Case Files. For K-12 Teachers

Marine food webs Feeding relationships are often shown as simple food chains – in reality, these relationships are much more complex, and the term ‘food web’ more accurately shows the links between producers, consumers and decomposers. A food web diagram illustrates ‘what eats what’ in a particular habitat. Pictures represent the organisms that make up the food web, and their feeding relationships are typically shown with arrows. Trophic levels Organisms in food webs are commonly divided into trophic levels. Food webs throughout the world all have the same basic trophic levels. Producers Producers are described as autotrophic, which means they are able to make their own food. Consumers Consumers are described as heterotrophic, which means they are unable to make their own food and rely on consuming other organisms or absorbing dissolved organic material in the water column. Consumers are divided into herbivores and carnivores and are typically further divided into 1st, 2nd or 3rd level consumers. Metadata
BioEd Online: Biology Teacher Resources, Lesson Plans is pleased to offer a new online series of podcasts and supplementary standards-based educational activities, research information, and links. National Space Biomedical Research Institute (NSBRI) researcher, Dr. Babs Soller of the University of Massachusetts Medical School, has been working to develop techniques for non-invasive measurement of blood and tissue chemistry. Her work can be used to help monitor the health of astronauts in space. National Space Biomedical Research Institute (NSBRI) scientist Scott Dulchavsky has developed a technique to train space flight crews to conduct medical-quality ultrasound imaging in space. David Dinges, a professor at the University of Pennsylvania School of Medicine, is working with the National Space Biomedical Research Institute (NSBRI) to develop a test that helps astronauts to gauge fatigue and stress during long missions in space.
