Bacteria naturally present in the human intestine, known as the gut microbiota, can transform cholesterol-derived bile acids into powerful metabolites that strengthen anti-cancer immunity by blocking androgen signaling, according to a preclinical study led by Weill Cornell Medicine investigators. The study was published on April 15 in Cell.

Nearly 200 scientists, investors and industry representatives attended Weill Cornell Medicine’s 2025 Biomedical Innovation Conference (“BioInnovate”) April 1, sharing their startup journeys and experiences nurturing biomedical advances into health care products and companies.

The conference, hosted in the institution’s Uris Auditorium, featured a fireside chat with venture capitalist Alex Gorsky, general partner at investment firm ICONIQ Growth and the former chairman and CEO of Johnson & Johnson, as well as panels comprised of innovators, industry leaders and investors.

Speaking with Dr. John P. Leonard, senior associate dean for innovation and initiatives at Weill Cornell Medicine, Gorsky recounted the trail great science takes as it travels from the world of research to patient care.

“I think part of the secret sauce of America is that we have collaboration between all those institutions (government, academia, private sector) that make great innovations and breakthroughs possible,” Gorsky said.

Dr. Sabine Ehrt

(New York, April 14, 2025)—Dr. Sabine Ehrt, an internationally renowned leader in tuberculosis research, has been appointed chair of the Department of Microbiology and Immunology at Weill Cornell Medicine, effective July 1.

The department, which is comprised of microbiologists and immunologists, focuses on the body’s interaction with microbes like viruses, bacteria and fungi, along with inflammatory and autoimmune disorders, with a focus on AIDS, malaria and tuberculosis. As chair, Dr. Ehrt seeks to build on the department’s already robust national and international footprint in tuberculosis research and expand its portfolio in other areas of research and innovation. Her goals include bringing on new faculty specializing in antimicrobial resistance and malaria, as well as scientists with skills beyond microbiology or who deploy innovative approaches. She is committed to fostering cross-disciplinary and cross-departmental collaborations, including with the Cornell Center for Antimicrobial Resistance Research and Education and the College of Veterinary Medicine at Cornell’s Ithaca campus. She also wants to boost the mentorship of junior faculty to facilitate their success.
