CHATGPT'S NEW IMAGES 2.0 MODEL IS SURPRISINGLY GOOD AT GENERATING TEXT

OpenAI's new image generation model has thinking capabilities and can search the web, make multiple images from one prompt, and double-check its creations. The model has a stronger understanding of non-Latin text than previous models. It can render fine-grained elements like small text, iconography, UI elements, dense compositions, and subtle stylistic constraints, all at up to 2K resolution. The model is available to ChatGPT and Codex users and via the gpt-image-2 API.

BLUE ORIGIN ROCKET GROUNDED AFTER SATELLITE 'MISHAP'

The Federal Aviation Administration has grounded Blue Origin's newest rocket to investigate a 'mishap' that involved the failed launch of a satellite. The rocket was used to place a satellite from AST SpaceMobile into orbit, but it missed its mark, and the satellite was unable to get as far into orbit as intended. Blue Origin claims the failure was caused by a lack of sufficient thrust in an engine. The investigation findings will determine when New Glenn can be launched again.

HUMBLE EMERGES FROM STEALTH WITH $24M AND A CABLELESS AUTONOMOUS ELECTRIC TRUCK BUILT TO GO DOCK-TO-DOCK

Humble is a San Francisco-based autonomous freight startup that just emerged from stealth with a $24 million seed round. The company's fully electric, cabless freight vehicle, the Humble Hauler, is built for 40-foot and 53-foot shipping containers. It has no driver's cab, allowing the company to fit 360-degree sensor coverage, free up payload capacity, and enable a fundamentally different vehicle geometry. The Hauler can operate dock-to-dock, delivering directly to the destination and unloading rather than dropping a trailer off at a handoff point.

ANNOUNCING TYPESCRIPT 7.0 BETA

TypeScript 7.0 Beta is built on a completely new foundation, making it about 10 times faster than TypeScript 6.0. Its Go codebase was methodically ported from TypeScript's implementation rather than rewritten from scratch, so its type-checking logic is structurally identical to TypeScript 6.0. Despite being in beta, TypeScript 7.0 is highly stable, highly compatible, and ready to be used in daily workflows and CI pipelines.

AGENTS WITH TASTE

Coding agents don't quite know what great feels like when it comes to visual work like animations. One way to get around this is to create a skill file for each aspect of an interface. Describe the rules of what 'great' feels like in that context and give that to agents so they can follow them. This results in AI that has the taste and knowledge to produce significantly better results.

WHAT PHYSICAL ‘LIFE FORCE' TURNS BIOLOGY'S WHEELS?

This article tells the story of how scientists figured out how the flagellar motor worked. The flagellar motor was discovered by Howard Berg, who set out in the early 1970s to apply his training in physics to understand how bacteria move. Bacteria move quickly, so Berg had to invent and build an automatic tracking microscope to keep them in view. He hypothesized how the mechanism worked 50 years before scientists discovered how the motor works.

QUANTUM COMPUTERS ARE NOT A THREAT TO 128-BIT SYMMETRIC KEYS

Both AES-128 and SHA-256 are safe against quantum computers. No symmetric key sizes have to change as part of the post-quantum transition. Almost all experts agree on this. The misconception is usually based on a misunderstanding of the applicability of a quantum algorithm called Grover's.

THE AI ENGINEERING STACK WE BUILT INTERNALLY — ON THE PLATFORM WE SHIP

93% of Cloudflare's R&D organization used AI coding tools powered by infrastructure that they built on their own platform. The team built its own MCP servers, access layer, and AI tooling necessary for agents to be useful at Cloudflare. This has had a significant impact on the number of merge requests made. The four week rolling average has climbed from around 5,600 per week to over 8,700. This post looks at how Cloudflare achieved this.

ANTHROPIC DEBUTS CLAUDE DESIGN FOR CREATING PROTOTYPES, PITCH DECKS, AND MOCKUPS

Claude Design can create designs, prototypes, slides, and more using Opus 4.7, an AI model that was introduced earlier this week. It can see images in greater resolution than Anthropic's previous models and is more 'tasteful and creative' when performing professional tasks. Claude Design allows founders, product managers, and marketers without a design background to create high-quality interfaces, slides, and docs. Teams in testing have been using it to create realistic prototypes, wireframes, mock-ups, design explorations, pitch decks, presentations, and social media assets. It is now available as a research preview for Claude Pro, Max, Team, and Enterprise customers.

BLUE ORIGIN SUCCESSFULLY RE-USES A NEW GLENN ROCKET FOR THE FIRST TIME EVER

Blue Origin successfully reused one of its New Glenn rockets, but the overall success of the mission is in question as the communications satellite that the rocket carried to space wound up in an off-nominal orbit. The company missed its target, which suggests something may have gone wrong with the rocket's upper stage. It is unclear whether the upper stage performed its second burn, scheduled an hour after the rocket lifted off. The re-use feat was achieved on just the third-ever launch of New Glenn.

PANCREATIC CANCER MRNA VACCINE SHOWS LASTING RESULTS IN AN EARLY TRIAL

mRNA vaccines, personalized for each individual using genetic material taken from their unique tumor cells, are showing promise in the fight against pancreatic cancer. These vaccines work as a type of immunotherapy that stamps out lingering, undetected cancer cells after surgery to remove larger tumors. Traditional immunotherapies only work in about 20% of all cancers, and pancreatic cancer is the poster child for difficult-to-treat cancers. The drugmakers behind the vaccine have now started Phase 2 clinical trials.
