SPACEX REVEALS WHY THE LAST TWO STARSHIPS FAILED AS ANOTHER LAUNCH DRAWS NEAR

SpaceX has received launch approval for the 10th full-scale test flight of its Starship rocket. The launch is scheduled for no earlier than August 24 at 6:30 pm local time in Texas.

BIOTECH'S LOST ARCHIVE

FDA submissions contain unparalleled details about the design of clinical trials, manufacturing processes, safety assessments, and reviewer correspondences, but this information is not publicly available. This article details a proposal for a legally grounded mechanism for democratizing FDA filings. Freeing FDA submissions from obscurity would level the playing field for small biotech firms, academic teams, and nonprofits and enable AI-driven regulatory intelligence tools that dramatically lower compliance costs and accelerate approval timelines. AI stands to revolutionize drug development, but only if it can be trained on high-quality unredacted datasets.

Search engines seem to be getting worse. Better quality results should rank higher than the prolific inorganic content and engagement bait everywhere today. Transformer-based text embedding models show amazing natural comprehension of language - this technology can be used to find great content, insights, and references. This article details a project where a developer tries to build a web search engine from scratch using neural embeddings. Embeddings appear far more powerful than traditional search.

35 THOUGHTS ABOUT AGI AND 1 ABOUT GPT-5

GPT-5's release felt uneventful. It is still not Artificial General Intelligence (AGI), and it still gets things wrong - the model is supposed to be able to decide for itself whether it needs to use its thinking mode for harder problems, but many reports show that it often gets this wrong. Large language models perform well with crystallized knowledge, which masks their shortcomings with fluid intelligence. AGI has the potential to change how we do everything very soon after it is achieved, but we still have to figure out how to get there.
