Evidence for dispersing 1D Majorana channels in an iron-based superconductor

期刊: SCIENCE, 2020; 367 (6473)

The possible realization of Majorana fermions as quasiparticle excitations in condensed-matter physics has created much excitement. Most studies have ......

Evolution of carnivorous traps from planar leaves through simple shifts in gene expression

期刊: SCIENCE, 2020; 367 (6473)

Leaves vary from planar sheets and needle-like structures to elaborate cup-shaped traps. Here, we show that in the carnivorous plant Utricularia gibba......

A single photonic cavity with two independent physical synthetic dimensions

期刊: SCIENCE, 2020; 367 (6473)

The concept of synthetic dimensions has generated interest in many branches of science, ranging from ultracold atomic physics to photonics, as it prov......

Oriented attachment induces fivefold twins by forming and decomposing high-energy grain boundaries

期刊: SCIENCE, 2020; 367 (6473)

Natural and synthetic nanoparticles composed of fivefold twinned crystal domains have distinct properties. The formation mechanism of these fivefold t......

Hydrophobic zeolite modification for in situ peroxide formation in methane oxidation to methanol

期刊: SCIENCE, 2020; 367 (6474)

Selective partial oxidation of methane to methanol suffers from low efficiency. Here, we report a heterogeneous catalyst system for enhanced methanol ......

Nearly quantized conductance plateau of vortex zero mode in an iron-based superconductor

期刊: SCIENCE, 2020; 367 (6474)

Majorana zero modes (MZMs) are spatially localized, zero-energy fractional quasiparticles with non-Abelian braiding statistics that hold promise for t......

Observation of an isomerizing double-well quantum system in the condensed phase

期刊: SCIENCE, 2020; 367 (6474)

Molecular isomerization fundamentally involves quantum states bound within a potential energy function with multiple minima. For isolated gas-phase mo......

Observation of hydrogen trapping at dislocations, grain boundaries, and precipitates

期刊: SCIENCE, 2020; 367 (6474)

Hydrogen embrittlement of high-strength steel is an obstacle for using these steels in sustainable energy production. Hydrogen embrittlement involves ......

Fetal mast cells mediate postnatal allergic responses dependent on maternal IgE

期刊: SCIENCE, 2020; 370 (6519)

Mast cells (MCs) are central effector cells in allergic reactions that are often mediated by immunoglobulin E (IgE). Allergies commonly start at an ea......

Autosomal dominant VCP hypomorph mutation impairs disaggregation of PHF-tau

期刊: SCIENCE, 2020; 370 (6519)

Neurodegeneration in Alzheimer's disease (AD) is closely associated with the accumulation of pathologic tau aggregates in the form of neurofibrillary ......

Architecture of the photosynthetic complex from a green sulfur bacterium

期刊: SCIENCE, 2020; 370 (6519)

The photosynthetic apparatus of green sulfur bacteria (GSB) contains a peripheral antenna chlorosome, light-harvesting Fenna-Matthews-Olson proteins (......

Integrated hearing and chewing modules decoupled in a Cretaceous stem therian mammal

期刊: SCIENCE, 2020; 367 (6475)

On the basis of multiple skeletal specimens from Liaoning, China, we report a new genus and species of Cretaceous stem therian mammal that displays de......
