Over the past couple of weeks, we’ve lost two legendary scientists who made major contributions to our world: Sir John Sulston and Stephen Hawking. Although they worked in very different areas of science—biology and physics—both have left us with an enduring legacy through their brilliant work that unlocked fundamental mysteries of life and the universe.
I had the privilege of working closely with John as part of the international Human Genome Project (HGP), a historic endeavor that successfully produced the first reference sequence of the human genetic blueprint nearly 15 years ago, in April 2003. As founding director of the Sanger Centre (now the Sanger Institute) in Cambridge, England, John oversaw the British contributions to this publicly funded effort. Throughout our many planning meetings and sometimes stormy weekly conference calls about progress of this intense and all-consuming enterprise, John stood out for his keen intellect and high ethical standards.

Seasons Greetings! What looks like a humble wreath actually represents an awe-inspiring gift to biomedical research: a new imaging technique that adds a dash of color to the formerly black-and-white world of electron microscopy (EM). Here the technique is used to visualize the uptake of cell-penetrating peptides (red) by the fluid-filled vesicles (green) of the endosome (gray), a cellular compartment involved in molecular transport. Without the use of color to draw sharp contrasts between the various structures, such details would not be readily visible.
This innovative technique has its origins in a wonderful holiday story. In December 2003, Roger Tsien, a world-renowned researcher at the University of California, San Diego (UCSD), decided to give himself a special present. With the lab phones still and email traffic slow for the holidays, Tsien decided to take advantage of the peace and quiet to spend two weeks alone at the research bench, pursuing an intriguing, yet seemingly wacky, idea. He wanted to find a way to deposit ions of a rare earth metal, called lanthanum, directly into cells as the vital first step in creating a new imaging technique designed to infuse EM with some much-needed color. After the holidays, when the lab returned to its usual hustle and bustle, Tsien handed off his project to Stephen Adams, a research scientist in his lab, thereby setting in motion a nearly 13-year quest to perfect the colorful new mode of EM.
Two Science Selections:
Horace Freeland Judson, Eighth Day of Creation. A comprehensive history of the origins and early science of the field of modern molecular biology, written by historian Horace Freeland Judson based on personal interviews with those who drove the revolution in biology. First and foremost are the science—DNA, RNA and protein, the genetic code, and gene regulation—and the scientific process—the seed ideas, the “aha” insights and the brilliant and elegant experiments. But this book is also the story of scientists in the process of discovery and of how the science that emerged was at least as much a consequence of the personalities as of the experimental skills of those involved. Fascinating, engaging, and fun—I’ve recommended this book to many, scientist and non-scientist alike.
Georgina Ferry, Dorothy Hodgkin. A superb biography of one of modern science’s most exceptional and distinguished pioneers. Awarded the Nobel Prize in Chemistry in 1964 for determining the crystal structures of penicillin and vitamin B12, Dorothy Crowfoot Hodgkin faced repeated challenges as a woman attempting to study and then pursue a career in chemistry in the 1930s and 1940s in England. Hodgkin is only one of four women ever awarded the Nobel Prize in Chemistry; the others were Marie Curie (1911); her daughter Irene Joliot-Curie (1935); and Ada Yonath (2009). Once recognized, Hodgkin worked hard to combat social inequalities and was president for more than a decade of Pugwash, an international organization founded by Bertrand Russell and dedicated to preventing war. Hodgkin has been a role model for many, although she disagreed rather strongly with the political views and actions of her most famous student, Margaret Thatcher.
George Klein, The Atheist and the Holy City. This book was a gift to me from George Klein, a Hungarian-Swedish tumor biologist and virologist at the Karolinska Institute in Stockholm. George and his wife Eva are best known in biological circles for their pioneering discovery of the role of the Epstein-Barr virus in Burkitt’s lymphoma and other neoplasms. This book, one of many George has written, is a compilation of essays that focus on science, but incorporate history, religion and philosophy. Its sections are entitled “The Wisdom and Folly of Scientists,” “Journeys,” “Viruses and Cancer” and “The Human Condition,” and collectively touch upon topics as diverse as DNA hybridization, the discovery of Rous sarcoma virus, and the life cycle of Schistosoma mansoni, as well as the Nazi death camps, scientific creativity, and the conviction that God is an example of man’s wishful thinking. Thought-provoking and uplifting, this book is a story of science and much more. A must read for all.
Robert Horvitz, Ph.D. is the David H. Koch Professor of Biology at the Massachusetts Institute of Technology, and a member of the MIT McGovern Institute for Brain Research and the MIT Koch Institute for Integrative Cancer Research. Dr. Horvitz is co-winner of the 2002 Nobel Prize in Physiology or Medicine for discoveries concerning genetic regulation of organ development and programmed cell death.

Summertime! Long weekends, a vacation, the threat of boredom. Time for uninterrupted reading—on beaches or in air-conditioned bedrooms. A chance to look beyond the best-seller lists or the daily news to dive, with full concentration, into one or two books that some friend has argued might be a life-changing experience. In that spirit, here are two for which I would make that argument to almost any friend.
In the sphere of science: The Age of Wonder: The Romantic Generation and the Discovery of the Beauty and Terror of Science, by Richard Holmes (HarperCollins, 2008). Holmes is primarily a literary biographer (of Coleridge and other Romantic poets), but also an art historian and a science junkie, who has written about ballooning and women scientists. Of the many books I’ve read about the growth of the scientific enterprise, The Age of Wonder stands out for several reasons: its deep engagement with the full range of cultural and political currents in which science arises; its focus on the excitement about discovery—geographical, astronomical, chemical, biological—that permeated the late 18th and early 19th centuries; and its absorption with personal histories of people who made those discoveries. Holmes is a superb storyteller and drawn to the complexities of life (especially in Britain) that influenced the talented people—Joseph Banks, Humphry Davy, several members of the Herschel family—who made novel observations that changed our perceptions of the world and solidified the place of science.
