The realm of DNA-based materials combines the way DNA is manipulated and handled inside our cells with innovative ways of thinking about material science outside, for industrial purposes.
About Davide Michieletto "I am a Professor of Biomaterials at the University of Edinburgh working on Topological Problems in Soft Matter and Biology. I am a 2024 Philip Leverhulme Prize Winner. I am the group leader of the Topological Active Polymers Lab. We aim to discover new DNA-based topological soft materials and complex fluids that can change properties in time. The group's expertise is rooted in polymer and statistical physics and employs both simulations and experiments to answer our questions. We believe boundaries between disciplines were made to be broken, and we do our best to shatter them every day."
Key Points • DNA can be used to create programmable materials with highly specific interactions, thanks to its unique sequence-based binding properties. • Viscoelastic materials, which behave as both liquids and solids, are common in biology. Cells and tissues are examples of biological objects that can behave as both solid and liquid. • Proteins that naturally manipulate DNA in cells can be repurposed to control the behavior of DNA-based materials in biotechnology. • DNA hydrogels offer promising applications, including tissue regeneration and bio-batteries, but large-scale production remains limited by the cost of DNA synthesis.

Ruthie's Table 4
For more than 30 years The River Cafe in London, has been the home-from-home of artists, architects, designers, actors, collectors, writers, activists, and politicians. Michael Caine, Glenn Close, JJ Abrams, Steve McQueen, Victoria and David Beckham, and Lily Allen, are just some of the people who love to call The River Cafe home. On River Cafe Table 4, Rogers sits down with her customers—who have become friends—to talk about food memories. Table 4 explores how food impacts every aspect of our lives. “Foods is politics, food is cultural, food is how you express love, food is about your heritage, it defines who you and who you want to be,” says Rogers. Each week, Rogers invites her guest to reminisce about family suppers and first dates, what they cook, how they eat when performing, the restaurants they choose, and what food they seek when they need comfort. And to punctuate each episode of Table 4, guests such as Ralph Fiennes, Emily Blunt, and Alfonso Cuarón, read their favourite recipe from one of the best-selling River Cafe cookbooks. Table 4 itself, is situated near The River Cafe’s open kitchen, close to the bright pink wood-fired oven and next to the glossy yellow pass, where Ruthie oversees the restaurant. You are invited to take a seat at this intimate table and join the conversation.
