Nobel Laureate Ada Yonath, Pioneer in Ribosome Structure, Dies at 87

Professor Ada Yonath, a Nobel Prize laureate in Chemistry and one of the world's most influential scientists, has passed away at the age of 87. Yonath, who was a faculty member at the Weizmann Institute of Science, was renowned for her groundbreaking research that elucidated the three-dimensional structure of the ribosome, the cellular organelle responsible for protein synthesis in all living organisms. This achievement earned her global recognition and numerous awards.

Born in Jerusalem in 1939, Yonath's research, which began in the 1970s, focused on a challenge considered nearly impossible by the scientific community at the time. She developed the technique of cryo-crystallography, which involves freezing biological crystals to map their atomic structure using X-rays. This innovation allowed her to present a detailed map of the ribosome, a discovery that significantly advanced the understanding of how antibiotic drugs bind to bacteria and disrupt their function. Her work has had direct implications for the development of new medications and the scientific battle against antibiotic resistance.

In 2009, Yonath was awarded the Nobel Prize in Chemistry, becoming the first Israeli woman to receive the prestigious award and the first woman in 45 years to win in that field. Throughout her distinguished scientific career, she received many other international honors, including the Wolf Prize, the L'Oréal-UNESCO Award for Women in Science, and the Israel Prize. Yonath pursued her higher education at the Hebrew University of Jerusalem for her bachelor's and master's degrees before completing her doctorate at the Weizmann Institute, where she remained a professor until her final days. She is survived by a daughter and grandchildren.
