Decoding a material’s ‘memory’
particles shown as gray dots with arrows and colored lines indicating their direction of movement

A suspension of particles of different sizes during shearing experiments conducted in the lab of Paulo Arratia, with arrows indicating particle “flow” and trajectories. In a new study published in Nature Physics, researchers detail the relationship between a disordered material’s individual particle arrangement and how it reacts to external stressors. The study also found that these materials have “memory” that can be used to predict how and when they will flow. (Image: Arratia lab)

Decoding a material’s ‘memory’

A new study details the relationship between particle structure and flow in disordered materials, insights that can be used to understand systems ranging from mudslides to biofilms.

Artist rendering of the Starshot Lightsail spacecraft during acceleration by a ground-based laser array. Previous conceptions of lightsails have imagined them being passively pushed by light from the sun, but Starshot’s laser-based approach requires rethinking the sail’s shape and composition so it won’t melt or tear during acceleration.

How to design a sail that won’t tear or melt on an interstellar voyage

The Breakthrough Starshot Initiative’s laser-based approach requires rethinking a sail’s shape and composition so it won’t melt or tear during acceleration and pushed by wind, not light.
