Moderna and Merck say intismeran plus Keytruda beat Keytruda alone on recurrence-free and distant-metastasis-free survival in 1,137 people whose high-risk melanoma had been surgically removed. It is the first positive Phase 3 result for an individualized neoantigen therapy and an mRNA-based cancer treatment. Each dose starts with mutations found in one patient’s tumor; an algorithm selects up to 34 neoantigens and encodes those targets into synthetic mRNA. This is not an approval or a cure claim: the companies have not yet released the effect sizes, detailed safety data, or an overall-survival result.

Subscriptions wake a cloud agent when a pull request, Slack thread, or schedule changes. /goal lets it keep an objective such as making flaky tests green. Subagents get isolated VMs, and steering messages wait for the next tool call instead of interrupting. The editor is becoming a standing labor pool, so the next practical question is what a runaway goal costs.

Google can buy as many as 58.97 million Marvell shares at $206.58. Nearly 1.4 million vest in year one; the rest sit in 240 tranches, each released by $500 million in custom-chip revenue through fiscal 2033. Fully vested, the warrant corresponds to roughly $120 billion of purchases. A supplier agreement just became a visible hyperscaler demand roadmap.

Private Safety Processing is a pilot aimed at bad human actors and misaligned agents attempting hacks through advanced models. The claim is that prompts and responses need not be retained. Bloomberg does not name the early customers or explain exactly how the classifier inspects content it will not keep. For zero-retention buyers, that unresolved mechanism is the whole question.

Pew surveyed 3,488 adults: 52% are more concerned than excited, up from 37% in 2021; only 9% lean the other way. Under-30 concern reached 55%, and 73% of that group now expects AI to cut jobs. The youngest constituency stopped being the easy pro-AI audience.

The Guardian tested the small white LED and points to a grey market for modified glasses with the light disabled. It also cites a Swedish investigation that found footage, including intimate recordings inside homes, had been reviewed by outsourced contractors in Nairobi to train Meta’s AI. Always-on cameras are entering public space faster than bystanders can identify them.

The London startup is reportedly in advanced talks to raise about $600 million at a $6.5 billion pre-money valuation after securing an Anthropic agreement for its inference chips. The tension is timing: Fractile is being priced as a serious Nvidia alternative before its first data-center chips are expected to ship in 2027. Frontier-lab demand is repricing hardware challengers before deployment evidence exists.

The plan expands Prime Air more than sixfold, beginning with suburban areas around Chicago, Atlanta, Cleveland, Syracuse, and Boise. Amazon is targeting 30 million customers and deliveries inside 30 minutes by year-end. The reality check: drones carry only five pounds, each launch site covers a limited area, local approvals remain, and Amazon has not shown that a one-package flight is cheaper than a truck stop.

The setup: if there is ever a movie about Musk, Kathy Bates should play him. Beneath the side-by-side is a two-word mock response: “Delete this.” The screenshot may not document a real exchange, but the casting is hard to unsee.
