Light-induced quantum friction of carbon nanotubes in water

Abstract Friction slows down moving objects at both macroscopic and microscopic scales1. At the electronic level, quantum friction describes direct transfer of momentum between a liquid and the electrons of a solid2. Owing to its microscopic nature, this phenomenon remains experimentally challenging to capture3.

Photoexcitation flips 2D moiré devices from metals to insulators in ultrafast test

June 4, 2026 feature Photoexcitation flips 2D moiré devices from metals to insulators in ultrafast test Ingrid Fadelli Author Sadie Harley Scientific Editor Robert Egan Associate Editor Quantum materials, materials with properties that are governed by the laws of quantum mechanics describing many-body interactions, have proved promising for the development of various advanced technologies. Many of these materials undergo so-called phase transitions, switching between different physical...

Logitech knows when to fold 'em

Logitech has unveiled the Mobi Fold mouse – a portable, foldable pointing device that could easily double as a replacement for a chunkier desktop version. It's the first foldable for Logitech, although alternatives have long been available. When you unfold it, it resembles something like Microsoft's Surface Arc mouse.

From exporting spyware to surveilling activists—how democracies became the new digital authoritarians

From exporting spyware to surveilling activists—how democracies became the new digital authoritarians Sadie Harley Scientific Editor Andrew Zinin Lead Editor "Digital authoritarianism" refers to governments using technology for surveillance and censorship to repress dissent. China remains the master practitioner. There, sweeping surveillance and censorship at home is combined with cyber-espionage and disinformation, censorship and influence campaigns abroad.

Defects, Corrugation and Temperature Govern Rarefied-Air Drag on Graphene Coatings

arXiv:2602.00285v3 Announce Type: replace-cross Abstract: In rarefied atmospheric environments, where continuum fluid dynamics breaks down, aerodynamic drag is governed by gas-surface momentum exchange, making surface structure and chemistry key design knobs. Using molecular dynamics simulations, we show that coating the $\alpha$-Al2O3(0001) surface with graphene markedly reduces the tangential momentum accommodation coefficient (TMAC) of N2, shifting scattering toward more specular...

How honeybees really crown their queens

How honeybees really crown their queens Sadie Harley Scientific Editor Robert Egan Associate Editor For generations, scientists believed a queen honeybee was made almost entirely by diet: feed an ordinary larva enough royal jelly and a ruler emerges. But new research suggests queens are created through a more elaborate process. Young worker bees construct specialized nursery chambers complete with custom wax, warmer temperatures, and devoted attendants that help determine whether a larva...

Logitech’s new Mobi Fold squeezes a lot of functionality into a tiny folding mouse

The Mobi Fold feels like a full-sized mouse when opened and includes a touch panel for scrolling. Logitech finally announced its new ultraportable travel mouse following leaked marketing images that spoiled the surprise last month. As the name implies, the Mobi Fold is a compact mouse that can fold in half using a hinge that can pivot about 130 degrees.

Coway Airmega Pedestal Fan P50 Review: Anti-App

I’ve tested nearly 45 fans for WIRED over the past two years, so I can say this with some authority: Your fan doesn’t need an app. If the app helps connect the device with your smart-home ecosystem to enable voice control, that’s fine, but a fan is supposed to blend unobtrusively into the background of your life, not take up any remaining scraps of real estate on your phone or in your brain. Coway, maker of some of our favorite air purifiers (which I will note are also app-free), agrees with...
