Ion transport through reconfigurable nanoparticle-surfactant stabilized droplet interface bilayers
Despite their adaptability and mechanical stability, Pickering emulsions based on the interfacial assembly of colloidal particles have not found use in iontronics, since the dense interfacial packing...
Everyone wants something better than ΛCDM
The current cosmological paradigm, ΛCDM, is characterized by its expansive description of the history of the Universe, its deep connections to particle physics and the large quantities of data that su...
Chen Ning “Frank” Yang (1922–2025): Profound proponent of symmetry
Chen Ning Yang made important contributions to the theory of solvable models in statistical mechanics, including generalizations of the Bethe Ansatz, magnetization in the Ising model, the Lee-Yang cir...
A lectin receptor-like kinase controls self-pollen recognition in <i>Phlox</i>
Self-incompatibility (SI) describes a widespread collection of genetic mechanisms in flowering plants used to specifically recognize and reject self-pollen. These mechanisms are fundamental to plant s...
Climate-driven reduction in biomass production of the Eurasian steppe coincides with nomadic migration during the first millennium CE
Although it is generally accepted today that climate and other environmental factors affected past human societies at different spatiotemporal scales, direct linkages are difficult to determine, and c...
Multiple formation pathways for amino acids in the early Solar System based on carbon and nitrogen isotopes in asteroid Bennu samples
Samples collected from the carbonaceous near-Earth asteroid Bennu and delivered to Earth by NASA’s OSIRIS-REx mission contain organic molecules relevant to prebiotic chemistry. Stable isotopic measure...
