Classroom Resource
The following classroom-ready resources complement The Making of the Fittest: The Birth and Death of Genes, which describes how scientists have pieced together the evolutionary history of the Antarctic icefish. The icefish makes an excellent case study for genetic evolution as both the gain and...
Short Film
Scientists have pieced together the evolutionary history of the Antarctic icefish. The icefish makes an excellent case study for genetic evolution as both the gain and loss of genes have led to key adaptations.
Click & Learn
An overview and comparison of different regenerative capabilities in many different organisms.
Classroom Resource
A simple activity that investigates the importance of antifreeze proteins to icefish survival.
Classroom Resource
A simple demonstration that uses readily-available materials to simulate how blood pumps through the circulatory system of icefish and other fish.
Classroom Resource
A dramatic demonstration that simulates how tiny ice crystals would form and grow in the blood of most fish if they ventured into the icy waters of the Antarctic.
Classroom Resource
A lesson that requires students to read detailed scientific passages and explain how an understanding of specific icefish adaptations might lead to a treatment or cure for human disorders, such as osteoporosis and anemia.
Video Clips
What do humans, flies, and worms have in common? More than you might think. See how transgenic organisms are engineered, and how they enable researchers to study genetic diseases.
Video Clips
Dr. Rosenthal uses a model of a heart and an artery to describe how blockages lead to heart attack and tissue damage.
Lectures
Dr. Hudspeth will begin by discussing how simple organisms—such as bacteria—have the capacity to detect and react to a stimulus.
Lectures
Dr. Nathans will discuss how the visual process involves the detection of light by photo-receptors in the retina.
Lectures
Dr. Hudspeth will explain the basis for the ear’s remarkable ability to detect sound through the hair cell, the sensory receptor found in the inner ear.
Lectures
Dr. Nathans will complete the lecture series by clarifying what is known about the brain’s ability to process and integrate various elements of the visual system, such as color, motion, and depth.
Lectures
Dr. Friedman introduces the genes and circuits that control appetite, including the key role of leptin.
Lectures
Dr. Evans describes how fat communicates with muscle and how diet and exercise influence that relationship.
Lectures
Dr. Evans reviews how PPARs regulate body weight by controlling whether fat is burned or stored.
Lectures
Dr. Friedman shows how leptin rewires neural circuits, and how population studies may identify obesity genes.
Lectures
A Q&A session on obesity and related issues, with the lecturers and students attending the Holiday Lectures on Science.
Lectures
Finding factors to reverse age-related loss of cell maintenance, and some examples of stem cell therapies.
Lectures
How a nerve cell gets its identity, sends axons, and makes connections with other cells.
Lectures
Understanding the neural circuits in the spinal cord that control movement.
Lectures
The cellular and molecular nature of learning and memory, investigated in simpler sea slugs and more-complex mice.
Lectures
Venomous carniverous cone snails are a rich source of molecules for scientific research and potential drug development.
Lectures
Cone snails have evolved many different toxins for different uses. Total molecular biodiversity may number in the millions.
Series
What medical secrets do venomous snails hold? How can listening in on bacterial conversations help develop new antibiotics? In four presentations, Dr. Bonnie L. Bassler and Dr. Baldomero M. Olivera reveal how a deeper understanding of nature and biodiversity informs their research into new...
