Introduction
Victoria Gray, a Black American woman now in her mid-thirties, was just three months old when she suffered her first painful bout with sickle cell disease (SCD), a debilitating genetic blood disorder. SCD is caused by a mutation of the hemoglobin-beta (HBB) gene in chromosome 11 that alters the shape of normally flexible, round red blood cells into rigid, crescent shaped cells. When it does, the flow of red blood cells that usually deliver oxygen to bodily tissues is restricted resulting in limited oxygen delivery to tissues and associated severe pain. Until recently, treatment consisted primarily of strong pain relief medication and, also, frequent blood transfusions. SCD affects about 100,000 people in the United States, more than 90% of whom are African-American or non-Hispanic Black, and millions more worldwide.
In 2019, Ms. Gray became the first patient with any form of genetic disease to be treated by gene-editing technology known as CRISPR which modified blood cells taken from her bone marrow for subsequent infusion back into her body. Two years later, she was not only pain free, but doing well enough to no longer be part of the landmark study for which she volunteered, although she will continue to be followed for fifteen more years in order to check the long-term safety and efficacy of her treatment.

Introduction
Biology is the scientific study of life, and Genesis is the biblical story of life. Both address matters ranging from the origin of life to how we find life today, and both contain lessons that are important for our continued existence. And despite the fact that differences of interpretation of Genesis and the Bible in general have been the source of much discussion about perceived conflicts between religious and scientific ideas, perhaps these perspectives need not be considered so divergent.
Genesis is the first book of the Hebrew Bible, and most Jews accept the idea that it contains metaphors and should not be intended to serve as a substitute or alternative for valid scientific textbooks. However, it is also true that close reading of these stories can reveal perspectives and themes in common with many contemporary issues of scientific interest and importance. For example, the field of biology is now reaching an unprecedented peak of experimental power. We can now change our own biology in ways that were unimaginable just a few years ago. This is not to say that we should not move ahead, but we need to do so carefully. Because of this unprecedented power, though, all biologists today would be well served to incorporate ethical and moral considerations into their work to consider what should be done, not just what can be done. The stories in Genesis can help here because they directly address many biological issues of current interest, and they may provide valuable philosophical and ethical perspectives. read more
