Quantum walks are demonstrated on a superconducting circuit.
- Electrified methane reforming: A compact approach to greener industrial hydrogen production
More-compact electrical heating of metal tube reactors increases catalyst usage and efficiency.
- A radiative cooling structural material
A process of delignification and reapplication of pressure creates a strong wood-based passive radiative cooling material.
- Anti-Markovnikov alcohols via epoxide hydrogenation through cooperative catalysis
Catalysis by chromium and titanium complexes forms alcohols by adding hydrogen to the more-substituted carbon of epoxides.

Crystal structures elucidate the active state of β-adrenergic receptors.
- Role of AcrAB-TolC multidrug efflux pump in drug-resistance acquisition by plasmid transfer
In the presence of antibiotics, a bacterial export pump allows protein translation to persist and thus safeguards resistance mechanisms.
- Shifting habitat mosaics and fish production across river basins
Mosaics of habitat increase resilience in salmon populations.
- Bacterial pseudokinase catalyzes protein polyglutamylation to inhibit the SidE-family ubiquitin ligases
A protein kinase fold in a bacterial effector protein catalyzes polyglutamylation, not phosphorylation.
About The Cover

COVER This 99-million-year-old scorpion, perfectly preserved in amber, is one of thousands of specimens offering an unprecedented view of the life of a Cretaceous forest. But the amber is typically excavated without scientific oversight in war-torn Myanmar, smuggled into China, and then sold in a commercial market. Chinese scientists are studying this specimen, which belongs to a private collection. See page 722.
