Forcing naïve species to live with enemies appears to help.
Feature
- Troubled treasure
Mined in a conflict zone and sold for profit, fossils in Burmese amber offer an exquisite view of the Cretaceous—and an ethical quandary.
Working Life

The Pohang quake shows the need for new methods to assess and manage evolving risk
Perspectives
- Improving sustainability with simpler alloys
The high performance of alloy materials can be maintained with compositional “plainification”
- Making chemicals with electricity
Hydrogen can be produced in electrically heated reactors, reducing CO2 emissions
- The importance of studying small earthquakes
Tiny earthquakes stitch together big ones
- Disseminating antibiotic resistance during treatment
A multidrug efflux pump can help bacteria acquire antibiotic resistance through plasmid transfer
- Crystal-clear treatment for allergic disease
Protein crystals could be targeted therapeutically to treat allergic pathology
Research Articles
- Brainstem nucleus incertus controls contextual memory formation
A brainstem regulatory mechanism for the selection of hippocampal neuronal assemblies during contextual learning is described.
- Protein crystallization promotes type 2 immunity and is reversible by antibody treatment
Gal10 crystals promote allergic disease, which can be reversed by antibody treatment.
- Germline selection shapes human mitochondrial DNA diversity
Human mitochondrial DNA undergoes selection in the female germ line and is shaped by the nuclear genome.
- Topological control of cytokine receptor signaling induces differential effects in hematopoiesis
Designed ligands tune cytokine receptor signaling.
Reports
- Strongly correlated quantum walks with a 12-qubit superconducting processor
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.
- Searching for hidden earthquakes in Southern California
A template-matching algorithm increases the number of earthquakes in the Southern California catalog by more than a factor of 10.
- Detecting nanometric displacements with optical ruler metrology
Superoscillation of a light field can be used to measure nanometer-scale displacements.
- Molecular basis for high-affinity agonist binding in GPCRs
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.
