For decades, fusion researchers struggled with neutron isotropy, a key indicator of scalable plasma.
Plasma is one of the four fundamental states of matter, along with solid, liquid, and gas. It is an ionized gas consisting of positive ions and free electrons. It was first described by chemist Irving Langmuir in the 1920s.
Simulations of a potential impact by a hill-sized space rock event next century have revealed the rough ride humanity would be in for, hinting at what it’d take for us to survive such a catastrophe.
It’s been a long, long time since Earth has been smacked by a large asteroid, but that doesn’t mean we’re in the clear. Space is teeming with rocks, and many of those are blithely zipping around on trajectories that could bring them into violent contact with our planet.
Optical information encoded in holograms is transferred by means of ultrashort laser filaments propagating in highly nonlinear and turbulent media. After propagation, the initial optical information is completely scrambled and cannot be retrieved by any experimental or physical modeling system. Yet, we demonstrate that neural networks trained on experimental data provide a robust way to fully recover the original hologram images. Remarkably, our approach demonstrates the ability to decode intricate spatial information, marking a significant advancement in information retrieval from chaotic media, with applications in secure free-space optical communications and cryptography.
They say space is silent, but turn your ears into radio wave receivers and suddenly it is a symphony of sounds. So what does Earth sound like from space? https://brilliant.org/astrum/

This study develops organ-specific aging models using blood proteomics data from 53,000 UK Biobank participants. These models predict organ-specific diseases and risk of death and reveal that chronic diseases reflect faster aging in specific organs. Different lifestyles affect organ aging differently.
