What changed between Opus 4.6 and 4.7.
The diff between two months of Claude's implicit instructions is a window into Anthropic's evolving definition of 'good behaviour': new guardrails, new affordances, and a much tighter stance on the model naming itself.

The fake-star economy is eating open source credibility.
Paid starring has become a quiet economy: agencies flip bundles of GitHub stars to make derivative AI wrappers look credible overnight. If you evaluate open source tools on stars, you're already being gamed.

Zuckerberg is reportedly building an AI clone of himself to sit in meetings.
Meta is testing an LLM version of its CEO for internal meetings. The interesting part isn't whether it works. It's whether 'show up as an agent' becomes an acceptable calendar reply.

The muon wobbles out of step with the Standard Model, again.
The 2026 Breakthrough Prize in Fundamental Physics went to the muon g-2 collaborations, whose decade-long measurement of a single magnetic moment has, at parts in a billion, refused to agree with theory. For twenty years physicists assumed the discrepancy was a computational mirage, a shadow of how hard it is to model the quark fog a muon swims through. The experimentalists held their number steady. The theorists refined their calculation. The gap did not close. The prize is, in effect, a bet that the gap is real: that the muon, by wobbling half a part per million faster than the Standard Model predicts, is pointing a very small finger at new physics. If correct, it is the first direct evidence of particles we have not yet discovered, hiding in the quantum vacuum around every muon ever measured.

Build a free, always-on, local AI agent in an afternoon.
$ cat openclaw.md
A dead-simple recipe for an always-on local agent that watches a folder, runs on your own hardware, and never phones home. Exactly the shape of tool a small team actually ships with: observable, auditable, and entirely yours.
> prerequisites: a laptop, ollama, 40 minutes
> cost: $0
> phone-home: no

TRELLIS.2 image-to-3D runs on Apple Silicon now.
The threshold for "can I spin up a 3D asset from a reference photo" just dropped to "open your laptop". Native M-series inference, no cloud, no queue. A decent input for a prototype, a thumbnail, a visual pitch, or a magazine-spread mockup.

Mochizuki returns, with a machine checker.
Two decades after claiming to prove the abc conjecture, Shinichi Mochizuki is back; this time he is formalising Inter-universal Teichmüller theory in Lean. If the proof goes through a machine checker, the twenty-year standoff ends in an afternoon.

Weird Science · Dispatch from under the churchyard
Eight million bees are living beneath a Welsh cemetery.
Naturalists surveying a Victorian-era churchyard in mid-Wales have found a single honeybee colony estimated at 8,000,000 individuals, nesting in the void beneath the cemetery floor. The colony has been burrowing through century-old coffin wood and capitalising, apparently, on the thermal stability of a stone-lined cavern with a convenient side entrance via 1860s masonry. Local beekeepers first noticed something was off when a plume of workers, larger than any recorded swarm in the county, emerged from a cracked headstone. Ground-penetrating radar confirmed the rest: a chambered, multi-storey nest stretching ten metres beneath consecrated ground. The colony is calm, disease-free, and, by one count, producing honey at a rate that would make a commercial apiary nervous. What the local vicar does with it is, evidently, an open question.

Half of America uses AI at work. Ten percent say it has changed the work.
The gap between adoption and transformation is where every serious AI programme, workshop, and product has to play. It is also the entire reason an AI education business exists at all.

Solar is now the single largest source of electricity on the planet.
Not "on track to". Not "projected". According to the IEA's April report, solar has overtaken every other energy source globally, coal included. A ten-year-old prediction that no one quite believed has, quietly, become the new baseline.
