Light and molecular handedness: From physical origins to the asymmetry of life

DLA Annual Conference 2026
Parallel Session A

Thursday, 28 May 2026
from 15:30 to 17:00

Leads
Prof. Burkhard König, University of Regensburg, Germany
Prof. Brian Norton, Tyndall National Institute, University College Cork and Technological University Dublin, Ireland
Dr Cornelia Meinert, Université Côte d’Azur, Nice, France

Description
This session explores the fascinating interplay between light and molecular handedness—also known as chirality—and its implications from fundamental physics to the origin of life. We will examine how light can induce or detect asymmetry in molecules, how this phenomenon is applied in modern science and technology, and what it may reveal about the emergence of biological asymmetry on early Earth. The session is designed to be accessible to an audience from diverse disciplines.

Objectives

• Introduce the physical principles of polarized light and how it interacts with chiral molecules.
• Highlight current applications of polarized light and chirality in chemistry, materials science, and medicine.
• Discuss potential consequences for the origin of life and the emergence of biological asymmetry.
• Foster interdisciplinary discussion and connect fundamental science
