Why has it been so hard to develop a vaccine against HIV? How are new medicines revolutionizing AIDS treatment? Can AIDS be cured?
In four presentations, Donald E. Ganem, MD, and B. Brett Finlay, PhD, discuss the latest advances in understanding how pathogens invade the body and how this knowledge is leading to the development of new therapies. They also explain how new infectious diseases are recognized and how epidemics...
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...
As part of the 2003 Holiday Lectures on Science, Dr. Bert Vogelstein and Dr. Huda Y. Zoghbi discuss how their patients have led to a deeper understanding of the genetic and molecular bases of neurological disorders and cancer. Thanks to these patients, researchers can now apply the knowledge...
In four talks, A. James Hudspeth, MD, PhD, and Jeremy H. Nathans, MD, PhD, discuss how sensory information is encoded and transmitted to the brain. They describe the detailed workings of two senses of great importance to humans—vision and hearing.
In the 2004 Holiday Lectures on Science, HHMI investigators Ronald M. Evans and Jeffrey M. Friedman discuss how the body regulates weight by carefully controlling the storage and burning of fat—and how a better understanding of these complex metabolic systems could lead researchers to...
Four talks focus on sex determination—the molecular and genetic mechanisms that determine whether an organism will be male, female or a hermaphrodite.
Four lectures highlight the research of two scientists who have made groundbreaking discoveries elucidating the molecular basis of circadian clocks—the internal timekeepers that govern fluctuations in behavior and physiology on a 24-hour cycle.
A wide overview of the immune system, presented by HHMI investigators John W. Kappler, PhD, and Philippa Marrack, PhD
In the 2013 Holiday Lectures on Science, leading medical researchers explain how advances in genomics are revolutionizing their work, leading to a better understanding of disease and to improved treatments.
