Blue Origin successfully re-uses a New Glenn rocket for the first time ever (3 minute read)

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 (8 minute read)

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.

The Agent Stack Bet (8 minute read)

Most 'production agents' shipping today feature custom plumbing, fragile session logic, shared service accounts, and weak security models. While models and tools have gotten dramatically better, there is a stack ceiling that is quietly creating a governance and reliability gap that agentic systems can't grow through. The current stack has excessive agency, with agents leaving a trail of corrupted state behind them. This article suggests four architectural bets teams should consider to move to the next generation of agentic systems.

Output isn't design (2 minute read)

Many people mistake design as the act of producing something. However, the hard part of design is actually understanding the problem enough to know what and how something should exist at all. There is use and place for tools, but the tools aren't part of the design process. Design is the search for a good fit between a form and its context. Good design considers human needs, technical constraints, conflicting requirements, habits, edge cases, and easy-to-miss relationships that require time to identify.
