    Discussion with Students on The Day The Mesozoic Died Short Film
    Lectures
    Students discuss the short film after a screening at the 2012 Holiday Lectures on Science.
    Sensory Transduction: Getting the Message
    Lectures
    Dr. Hudspeth will begin by discussing how simple organisms—such as bacteria—have the capacity to detect and react to a stimulus.
    The Science of Sight: Getting the Picture
    Lectures
    Dr. Nathans will discuss how the visual process involves the detection of light by photo-receptors in the retina.
    The Science of Sound: How Hearing Happens
    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.
    Neural Processing: Making Sense of Sensory Information
    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.
    Reading Genes and Genomes
    Lectures
    Dr. Eric Lander takes us on a tour of this remarkable genetic century, describing the rapid advances in DNA sequencing technologies and information science.
    Probing Genes and Genomes
    Lectures
    To understand life's processes, perturb them. How a process responds to an insult can provide clues about normal function or mimic a specific disease state.
    Human Genetics: A New Guide for Medicine
    Lectures
    Dr. Lander explores human genetic variation and how it may affect individual susceptibility to certain diseases.
    Chemical Genomics: New Tools for Medicine
    Lectures
    Scientists now have the ability to create millions of new molecules. How do they test whether any of these molecules are useful?
    Research Mechanics: Putting the Brakes on Cancer
    Lectures
    Although there are numerous kinds of cancer, all stem from alterations that allow cell division to outstrip cell demise.
    Chaos to Cure: Bringing Basic Research to Patients
    Lectures
    The identification of hundreds of genes involved in the formation and spread of cancer is leading to promising new methods for diagnosis, prevention, and treatment.
    A Healthy Nervous System: A Delicate Balance
    Lectures
    Mutations in key genes can lay waste to the nervous system. By studying large families predisposed to developing these genetic disorders, scientists can identify the responsible altered gene.
    The Strength of Families: Solving Rett Syndrome
    Lectures
    Girls with Rett syndrome develop normally for about 18 months and then begin to regress. With the help of affected girls and their families, Dr. Zoghbi and her collaborators searched for the gene responsible for this neurological disorder.
    Bioethics Discussion
    Lectures
    Genetic research benefits health, but also raises thorny ethical issues.
    Deconstructing Obesity
    Lectures
    Dr. Friedman introduces the genes and circuits that control appetite, including the key role of leptin.
    Understanding Fat: Syndrome X and Beyond
    Lectures
    Dr. Evans describes how fat communicates with muscle and how diet and exercise influence that relationship.
    Balancing the Fat Equation
    Lectures
    Dr. Evans reviews how PPARs regulate body weight by controlling whether fat is burned or stored.
    Exploring Obesity: From the Depths of the Brain to the Far Pacific
    Lectures
    Dr. Friedman shows how leptin rewires neural circuits, and how population studies may identify obesity genes.
    Student Discussion Session on Obesity
    Lectures
    A Q&A session on obesity and related issues, with the lecturers and students attending the Holiday Lectures on Science.
    Endless Forms Most Beautiful
    Lectures
    How Darwin came to publish The Origin of Species, and examples of how quickly evolution can change a population.
    Selection in Action
    Lectures
    Comparing the artificial selection of dogs and corn with the natural selection of the stickleback fish.
    Fossils, Genes, and Embryos
    Lectures
    The genetic mechanisms by which evolution occurs, and an overview of the evidence for evolutionary theory.
    From Butterflies to Humans
    Lectures
    How and why butterflies and fruit flies got their spots, and the fossil record for human evolution.
    Reconciling Religion and Science
    Lectures
    A discussion on reconciling religion and science with students, the lecturers, and guest speakers.
    Fossils, Genes, and Mousetraps
    Lectures
    Leading evolution educator Ken Miller discusses the controversy surrounding the teaching of evolution.
