Pinpoint simulations provide perspective on universe structure
Wednesday, 15 March 2023 03:13
The universe is peppered with galaxies, which, on large scales, exhibit a filamentary pattern, referred to as the cosmic web. This heterogeneous distribution of cosmic material is in some ways like blueberries in a muffin where material clusters in certain areas but may be lacking in others.
Based on a series of simulations, researchers have begun to probe the heterogeneous structure of th Princeton Chem, IAS uncover spatial patterns in distribution of galaxies

Mix-and-match kit could enable astronauts to build a menagerie of lunar exploration bots
Tuesday, 14 March 2023 13:21
When astronauts begin to build a permanent base on the moon, as NASA plans to do in the coming years, they'll need help. Robots could potentially do the heavy lifting by laying cables, deploying solar panels, erecting communications towers, and building habitats. But if each robot is designed for a specific action or task, a moon base could become overrun by a zoo of machines, each with its own unique parts and protocols.
