About
Trace Neuroscience launched with $101 million in Series A financing from Third Rock Ventures, Atlas Venture, GV (Google Ventures), and RA Capital Management, developing TRCN-1023 — an antisense oligonucleotide (ASO) that corrects UNC13A mRNA splicing defects that have been genetically validated as a driver of ALS (amyotrophic lateral sclerosis). The company went directly to ALS patient enrollment in early 2026, bypassing the healthy volunteer phase typical of first-in-human trials, reflecting confidence in the mechanism's tolerability profile.

About
Grok is the AI assistant developed by xAI, Elon Musk's AI company founded in 2023, and distributed primarily through X (formerly Twitter). Grok launched in November 2023 as an X Premium perk, with the notable differentiator of real-time access to X posts and a less restricted, more direct conversational style. Grok 3, released in February 2025, achieved top scores on the AIME math reasoning benchmark and ARC-AGI test, briefly positioning xAI as a frontier model lab.
