Simulations Suggest JWST's 'Little Red Dots' Are Infant Supermassive Black Holes

A new Nature study led by Max Planck Institute astrophysicist Sunmyon Chon simulated conditions in the early universe and found that rapidly forming black holes can generate light signatures matching the mysterious 'little red dots' seen by the James Webb Space Telescope. The team argues these objects quickly develop dense, thick gas disks that produce a strong hydrogen-alpha glow resembling what's observed in these ancient regions of space.

JWST spots 'little red dots' that defy simple black hole explanation

Astronomers using the James Webb Space Telescope had largely concluded that mysterious compact objects called 'little red dots' were supermassive black holes obscured by dust. But two newly analyzed dots studied by teams led by de Graaff and Naidu show a distinctive Balmer break—a spectral signature usually associated with hot stellar surfaces—that standard black hole models don't produce, complicating the picture.

Independent developer trains 3.8B-parameter LLM for under $1,000 on rented B200 GPUs

Hugo Vergnes built a config-driven training framework called little-lm and used it to train a 3.8-billion-parameter language model from scratch on 65 billion tokens, taking 43 hours on eight rented B200 GPUs at a total cost of $998. The model scored 0.384 on the CORE benchmark, outperforming Andrej Karpathy's nanochat d32 model, which cost about the same to train but scored 0.310.

Little League Coach's Loss-Speech Goes Viral, Resonates With Business Leaders

Cory Edwards, a Starbucks manager who coaches Little League in Henderson, Nevada, gave his team an unscripted pep talk while trailing 11-2 in the World Series final, telling them to hold their heads high and get tougher under pressure. ESPN's clip of the moment spread widely online, and Edwards later told The New York Times the message was really about character, not the scoreboard.
