Researchers isolated human-derived antibodies that protect against malaria, and protein-structure studies revealed the antibodies’ site of attack. The discovery paves the way for the development of a more effective and practical human vaccine for malaria, which is responsible for half a million deaths every year. Read more »
Science Highlights
Molecular Anvils Trigger Chemical Reactions
“Molecular anvils” (diamondoids) were used to trigger chemical reactions using pressure, yielding products that differ from those produced in conventionally driven reactions with the same reactants. The discovery opens up new possibilities for the high-specificity synthesis of valuable but challenging molecules in an environmentally friendly process. Read more »
The Electronic Structure of a “Kagome” Material
Scientists have verified exotic electronic properties predicted to emerge in a ferromagnetic material with “kagome” (trihexagonal) lattice symmetry. The greater understanding of kagome materials afforded by this work helps open up a new path toward goals such as ultralow-power electronic devices and quantum computing. Read more »
Rational Optimization of Organic Solar-Cell Materials
Researchers have established a new quantitative model that connects molecular interactions in organic solar-cell materials to device performance.

Toward Control of Spin States for Molecular Electronics
Researchers demonstrated, via x-ray absorption spectroscopy, that a molecule’s spin state can be reversibly switched at constant room temperature by magnetism. The results represent a major step toward the goal of programmable, nanoscale molecular electronics for high-speed, low-power, logic and memory applications. Read more »
Phase Diagram Leads the Way to Tailored Metamaterial Responses
Researchers discovered an innovative way to independently control two optical responses in a single-material system by utilizing the material’s phase diagram. This unique combination of material, methods, and results could lead to a paradigm shift in the design of metamaterial devices that manipulate light. Read more »
Tuning the Electronic Structure of a 2D Material
The electronic structure of a stacked 2D material was tuned by in situ electron doping, resulting in a large increase in the splitting of two valence bands. Stacked 2D materials possess an array of tunable properties that are expected to be important for future applications in electronics and optics. Read more »
Unraveling the Complexities of Auto-Oxidation
Researchers directly observed the formation of highly oxygenated molecules—the elusive products of auto-oxidation reactions relevant to combustion and atmospheric chemistry. A better understanding of auto-oxidation mechanisms could lead to better engines, less air pollution, and improved climate models. Read more »
