Imaging by flat lens using negative refraction
The positive refractive index of conventional optical lenses means that they need curved surfaces to form an image, whereas a negative index of refraction allows a flat slab of a material to behave as a lens a...

Coexistence of Fermi arcs and Fermi pockets in a high-Tc copper oxide superconductor
One outstanding puzzle in high-temperature cuprate superconductors relates to the 'Fermi surface pocket' that is expected to emerge when the material is slightly doped or underdoped. Such pockets were recently...

Open AccessPromotion of water-mediated carbon removal by nanostructured barium oxide/nickel interfaces in solid oxide fuel cells
The existing Ni-yttria-stabilized zirconia anodes in solid oxide fuel cells (SOFCs) perform poorly in carbon-containing fuels because of coking and deactivation at desired operating temperatures. Here we repor...

Ultrahard nanotwinned cubic boron nitride
The hardness, toughness and chemical stability of the well-known superhard material cubic boron nitride have been improved by using a synthesis technique based on specially prepared ‘onion-like’ precursor mate...

Open AccessEffects of genetically modified T2A-1 rice on the GI health of rats after 90-day supplement
Bacillus thuringiensis insecticidal toxin (Bt) rice will be commercialized as a main food source. Traditional safety assessments on genetically modified products pay little attention on gastrointestinal (GI) heal...

Open AccessEvolution of Topological Surface States in Antimony Ultra-Thin Films
Based on an inverted bulk band order, antimony thin films presumably could become topological insulators if quantum confinement effect opens up a gap in the bulk bands. Coupling between topological surface sta...

Open AccessRandomly broken fragment PCR with 5′ end-directed adaptor for genome walking
Many genome walking methods based on polymerase chain reaction (PCR) are available, including those with and without restriction enzyme modification. Nevertheless, these methods suffer from low reproducibility...

Open AccessPorphyrin–phospholipid liposomes permeabilized by near-infrared light
The delivery of therapeutic compounds to target tissues is a central challenge in treating disease. Externally controlled drug release systems hold potential to selectively enhance localized delivery. Here we ...

Nanotwinned diamond with unprecedented hardness and stability
Nanotwinned diamond synthesized with onion carbon nanoparticles as precursors has much higher hardness and thermal stability than natural diamond; its enhanced hardness is due to the reduced size of its twin s...

Open AccessOchratoxin A induced early hepatotoxicity: new mechanistic insights from microRNA, mRNA and proteomic profiling studies
The mycotoxin ochratoxin A (OTA) is found widely in agricultural commodities. OTA can induce various toxicities. In this study, rats were gavaged with OTA for different weeks. Then, the expression of microRNAs...

Aridity threshold in controlling ecosystem nitrogen cycling in arid and semi-arid grasslands
Higher aridity and more extreme rainfall events in drylands are predicted due to climate change. Yet, it is unclear how changing precipitation regimes may affect nitrogen (N) cycling, especially in areas with ...

Ultrafast quenching of electron–boson interaction and superconducting gap in a cuprate superconductor
Ultrafast spectroscopy is an emerging technique with great promise in the study of quantum materials, as it makes it possible to track similarities and correlations that are not evident near equilibrium. Thus ...

Open AccessSynthesis of high density aviation fuel with cyclopentanol derived from lignocellulose
For the first time, renewable high density aviation fuels were synthesized at high overall yield (95.6%) by the Guerbet reaction of cyclopentanol which can be derived from lignocellulose, followed by the hydro...

Open AccessRetinoic acid homeostasis through aldh1a2 and cyp26a1 mediates meiotic entry in Nile tilapia (Oreochromis niloticus)
Meiosis is a process unique to the differentiation of germ cells. Retinoic acid (RA) is the key factor controlling the sex-specific timing of meiotic initiation in tetrapods; however, the role of RA in meiotic...

Open AccessA Phytophthora sojae cytoplasmic effector mediates disease resistance and abiotic stress tolerance in Nicotiana benthamiana
Each oomycete pathogen encodes a large number of effectors. Some effectors can be used in crop disease resistance breeding, such as to accelerate R gene cloning and utilisation. Since cytoplasmic effectors may ca...
