Super-resolution in ultrafast scattering

moleculesSuper-resolution microscopy has transformed the way we view the biological world, and enabled scientists to visualize biological structures and their interactions inside cells, at a resolution of a few nanometers. But 'seeing' atomic motion in space and time is not straightforward. Researchers set out do something similar and see how individual atoms move in a molecule using X-rays. The result is an approach to extend super-resolution imaging to the challenging case of ultrafast scattering.

Exploring the frontiers of neuromorphic engineering: A journey into brain-inspired computing

neuronsNeuromorphic engineering is focused on developing computer hardware and software systems that mimic the structure, function, and behavior of the human brain. The goal of neuromorphic engineering is to create computing systems that are much more energy-efficient, scalable, and adaptive than conventional computer systems, and that can solve complex problems in a manner that is similar to how the brain solves problems. Neuromorphic computing is a specific application of neuromorphic engineering. It involves the use of hardware and software systems that are designed to process information in a manner that is similar to how the human brain processes information.
