Gleb Zilberstein is my guest in this episode of the Physics World Weekly podcast. A physicist by training, Zilberstein applies the principles of proteomics to the study of historical objects including Renaissance manuscripts.

He is also a director of Israel-based SpringStyle Tech Design, which has created a special film that lifts proteins from the surfaces of historical objects. Analysis of these proteins provides important information about how those objects were used.

In a recent paper, Zilberstein and colleagues studied protein residues on a well-thumbed book of medical recipes that was published in Germany in 1531. He explains how their analysis provides a new view into how medical practitioners used the book and what sorts of concoctions they were making. Astonishingly, the team found evidence that European readers had access to ingredients derived from hippopotamuses.

Some papers about the application of proteomics to historical research:

• The Scientific Analysis of Renaissance Recipes
• Count Dracula Resurrected
• EVA Technology and Proteomics: A Two-Pronged Attack on Cultural Heritage

The physicist and venture capitalist Alexandra Vidyuk is our guest in this episode of the Physics World Weekly podcast. She is the chief executive and founding partner of Beyond Earth Ventures, which provides funding and support to early-stage companies in deep-tech sectors including space, robotics and energy.

In conversation with Physics World’s Margaret Harris, Vidyuk explains how her BSc in applied mathematics and physics and her early career in banking and fintech set her on a path to deep-tech venture capital.

Vidyuk talks about the specific challenges facing deep-tech entrepreneurs and reveals what she looks for when deciding which companies to fund. She also emphasizes the importance of building an organization that understands its customers and can communicate effectively with them.

This episode of the Physics World Weekly podcast features Brian Pogue, who is professor of biomedical engineering at Dartmouth College in the US. He is also the co-founder of several start-up companies that are developing optics-based systems for medicine.

In conversation with Physics World’s Tami Freeman, Pogue explains that optical technologies underlie many of today’s routine medical procedures. The field of optics is also converging with the world of medical physics, and Pogue talks about exciting new techniques for guidance, dosimetry and in vivo verification of radiation therapy cancer treatments.
