Self-assembling magnetic microparticles mimic biological error correction

Everybody makes mistakes. Biology is no different. However, living organisms have certain error-correction mechanisms that enable their biomolecules to assemble and function despite the defective slough that is a natural byproduct of the process.

A Cornell-led collaboration has developed microscale that can mimic the ability of biological materials such as proteins and nucleic acids to self-assemble into complex structures, while also selectively reducing the parasitic waste that would otherwise clog up production.

This magnetic assembly platform could one day usher in a new class of self-building biomimetic devices and microscale machines.

Quantum ‘curvature’ warps electron flow, hinting at new electronics possibilities

How can data be processed at lightning speed, or electricity conducted without loss? To achieve this, scientists and industry alike are turning to quantum materials, governed by the laws of the infinitesimal. Designing such materials requires a detailed understanding of atomic phenomena, much of which remains unexplored.

A team from the University of Geneva (UNIGE), in collaboration with the University of Salerno and the CNR-SPIN Institute (Italy), has taken a major step forward by uncovering a hidden geometry—until now purely theoretical—that distorts the trajectories of electrons in much the same way gravity bends the path of light. The work, published in Science, opens new avenues for .

Future technologies depend on high-performance materials with unprecedented properties, rooted in quantum physics. At the heart of this revolution lies the study of matter at the microscopic scale—the very essence of . In the past century, exploring atoms, electrons and photons within materials gave rise to transistors and, ultimately, to modern computing.
