Plenty of groups have been theorizing about Primordial Black Holes (PBHs) recently. That is in part because of their candidacy as a potential source of dark matter. But, if they existed, they also had other roles to play in the early universe. According to a recent draft paper released on arXiv by Jeremy Mould and Adam Batten of Swinburne University, one of those roles could be as the seeds that eventually form both quasars and radio galaxies.

Neuromorphic cameras, which only record data when a pixel's brightness changes, may be advantageous for capturing extremely bright and dim objects in the same image and tracking fast-moving objects

Scientists are uncovering how spinning black holes launch jets, warp spacetime and shape the cosmos

A conversation with Anthropic’s chatbot raises questions about how AI talks about awareness.

New research suggests that primordial black holes could have played an important role in the formation of the universe's first stars, but did they help or hinder?

Data from ESA’s Soil Moisture and Ocean Salinity (SMOS) mission can be used to estimate how much carbon is stored in forests – and a study has improved our understanding of how reliable this proxy is and how long-term datasets from SMOS can help us to monitor this valuable resource.
