As a pioneer in cancer immunotherapy, Jim Allison has spent decades tackling major scientific challenges. So it’s interesting that Allison would consider one of the top five moments in his life jamming onstage with country star Willie Nelson. Yes, in addition to being a top-flight scientist at the University of Texas MD Anderson Cancer Center, Houston, Allison plays a mean harmonica.
Allison taught himself how to bend notes on the harmonica as a teenager growing up in a small Texas town. By his 20s, Allison was good enough to jam a couple of nights a week with the now legendary Clay Blaker & the Texas Honky Tonk Band. When Blaker asked if he wanted to hit the road with the band, Allison declined. He had his postdoctoral training to finish in molecular immunology.

Zachary Morris has certainly done some memorable things. As a Rhodes Scholar, he once attended an evening reception at Buckingham Palace, played a game of pick-up football with former President Bill Clinton, and traveled to South Africa to take a Robben Island Prison tour, led by the late Nelson Mandela. But something the young radiation oncologist did during his medical residency could prove even more momentous. He received a special opportunity from the American Board of Radiology to join others in studying how to pair radiation therapy with the emerging cancer treatment strategy of immunotherapy.
Morris’s studies in animals showed that the two treatments have a unique synergy, generating a sustained tumor-specific immune response that’s more potent than either therapy alone. But getting this combination therapy just right to optimize its cancer-fighting abilities remains complicated. Morris, now a researcher and clinician at the University of Wisconsin School of Medicine and Public Health, Madison, has received a 2017 NIH Director’s Early Independence Award to look deeper into this promising approach. He and his collaborators will use what they learn to better inform their future early stage clinical trials of radio-immunotherapy starting with melanoma, head and neck cancers, and neuroblastoma.

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.

For nearly 20 years, Hao Wu has studied innate immunity, our body’s first line of defense against infection. One of her research specialties is the challenging technique of X-ray crystallography, which she uses to capture the atomic structure of key molecules that drive an inflammatory response. But for this method to work, the proteins have to be coaxed to form regular crystals—and that has often proven to be prohibitively difficult. Wu, now at Boston Children’s Hospital and Harvard Medical School, can be relentless in her attempts to crystallize difficult molecular structures, and this quality has helped her make a number of important discoveries. Among them is the seminal finding that innate immune cells process and internalize signals to handle invading microbes much differently than previously thought.
Innate immune cells, which include macrophages and neutrophils, patrol the body non-specifically, keeping a look out for signs of anything unusual. Using protein receptors displayed on their surfaces, these cells can sense distinctive molecular patterns on microbes, prompting an immediate response at the site of infection.
Wu has shown that these cells form previously unknown protein complexes that mediate the immune response [1, 2]. She received an NIH Director’s 2015 Pioneer Award to help translate her expertise in the structural biology of these signaling complexes into the design of new kinds of anti-inflammatory treatments. This award helps exceptionally creative scientists to pioneer transformative approaches to major challenges in biomedical and behavioral research.
