The Quantum Computer That Borrowed Anyons

The most expensive trick in a useful quantum computer may have just met a rival. In the standard playbook for fault-tolerant quantum computing, noisy physical qubits are assembled into cleaner logical ones. That is only the beginning. To perform arbitrary...

The headline on this one writes itself, so let me get it out of the way: a 1,600-year-old Egyptian mummy, excavated from a Roman-era tomb at Oxyrhynchus, was found to have a fragment of Homer’s Iliad packed inside its wrappings \u2014 specifically into the...

Galaxies that died early, and the scars they don’t show

Two years ago, a paper in Nature announced a single strange object: a galaxy at redshift 4.65, already as massive as a respectable present-day disk, and already done forming stars. The universe was about 1.4 billion years old. The galaxy had no business being retired....

The Arctic isn’t draining \u2014 it’s rearranging

If you’ve only read the headlines, you’d think the Arctic is on a one-way slide to zero. Mid-July 2026 sits at roughly 4.28 million km² of sea ice, per NSIDC’s Charctic — about 540,000 km² under the 1991–2020 median, and well outside the 1979–2010...
