• Hacker News1Gemini 4 ArgonImpressive prose and general-purpose answers:Users praise Argon's clear, structured, direct answers, interactive simulations, health explanations, and natural writing, even in non-English languages. Coding ability is disputed: some find it on par with Opus 5.5, others call it weak. The return of em-dashes sparked a side debate.Confusing access, payments, and rollout:Many describe Google's UX as a mess. Users face rejected cards, locked accounts, confusing product names (Gemini, AI Studio, Antigravity), and "Try" buttons that default to older models. Argon is limited to Ultra subscribers, which critics say squandered the launch hype.Pelican SVG benchmark and Goodhart's law:Simon Willison calls Argon's pelicans the best yet and notes Google trains on SVG output. Others question benchmark gaming and debate whether the bikes' fork geometry is rideable. Some ask for harder tests, while others argue better SVG skills are genuinely useful.
• Reddit science1Creatine, the cheap gym supplement, protected the brain from gut inflammation in rats with chronic colitis. It blocked brain inflammation, neuron loss and faulty electrical signals in the brain's memory center (hippocampus). Male rats were hit much harder than females. It's not yet tested in humans.In rats with chronic colitis, creatine supplements prevented hippocampal inflammation, neuron damage, and altered electrical activity. Males were far more affected than females. Researchers caution the findings tested prevention, not treatment, and remain unconfirmed in humans.Rat dosage vs. human relevance:Rats got 1g/kg daily plus a loading dose, roughly 80-90g+ for humans versus typical 5-20g doses. Some questioned whether rats drank it all or raised allometric scaling. One comment stressed the results are rat-only and need human study.How creatine works and personal experiences:An exercise physiology student said creatine fuels quick energy rather than building muscle. Others cited recovery, training volume and water retention. Anecdotes ranged from 2kg water gain with no strength boost to relief from brain fog; one user's high dose was criticized.Kidney safety and lab tests:Creatine falsely raises serum creatinine, making kidney function look worse without real damage, and 5g/day was called safe. Users recommended a Cystatin C test; one said their doctor mistook lifting-skewed labs for early kidney failure.
