A new series titled "Thinkers of Tomorrow," published by the German media outlet Die Zeit, profiles seven intellectuals and scientists who are working to solve some of the biggest challenges of our time. These experts come from diverse fields such as digital geopolitics, artificial intelligence, law, architecture, geriatrics, climate science, and philosophy. The series includes notable figures like Hannah Ritchie, Katharina Pistor, Francis Kéré, and Fei-Fei Li, all of whom are making significant contributions to their respective areas of study. Among the individuals highlighted is Chiara Herzog, a bio-informatician who leads a research group on aging processes at King's College in London. Since May 1st, she has also been conducting research at the University of Cambridge. Herzog's work focuses on developing protocols to measure human body aging, with the aim of slowing the aging process and increasing the number of years people can live healthily, rather than simply extending lifespan. Her research centers on epigenetics, which involves studying small changes in how genes are expressed. These changes create a dynamic pattern that interacts with our genetic makeup and can provide insights into a person’s past, current health, and potential future, such as whether they have smoked or their risk of developing certain diseases. In addition to her aging research, Herzog has developed a new screening test for endometrial cancer in collaboration with a team from the University of Innsbruck in Austria. Unlike traditional methods that often require painful biopsies following ultrasound exams, this new test uses less invasive swabs. This advancement has the potential to replace more conventional screening techniques in most cases, offering a more comfortable and efficient alternative for patients. Herzog emphasizes that our understanding of women's aging remains limited, especially concerning the effects of hormone levels at various stages of life—before, during, and after menopause—and the differences in the female immune system compared to that of men. She points out that many clinical studies are conducted exclusively on men, which can lead to gaps in understanding and treatment for women. In response, Herzog has chosen to focus her research on cancers that predominantly affect women, aiming to address these disparities and improve health outcomes for women.
