Zika virus tested in brain precursor cells

Zika virus preferentially kills developing brain cells, a new study reports. The results offer evidence for how Zika virus may cause brain defects in babies – and specifically microcephaly, a rare birth defect in which the brain fails to grow properly.

Current methods cannot predict damage to coral reefs

Coral reefs are severely endangered by a warming and increasingly acidic ocean. Although species-level effects have been studied, these pieces of the puzzle have not been assembled into a broader view. Ecosystem-level effects may be more severe than is currently anticipated.

New cloud measurements are predicting a warmer climate

Models that aim to predict human-induced global average temperature rise have been underestimating important contributions from clouds, perhaps causing projections to be, in some simulations, as much as 1.3°C lower than what might occur, a new study suggests.

Mirror-twin induced bicrystalline inAs nanoleaves

This study reveals the formation of bicrystalline InAs nanoleaves driven by catalyst energy minimization. The relatively low-energy {122} or {133} mirror twins lead to the identical lateral growth of twinned structured, which results in the symmetrical formation of nanoleaves. A bio-inspired nanotechnology design can be created for future electronic or optoelectronic devices by correlating the structure of InAs nanoleaves in the nanoworld and that of real leaves in the natural world.

Novel synthesis of N-doped graphene as an efficient electrocatalyst towards oxygen reduction

N-doped porous graphene was successfully synthesized by a simple and scalable bottom-up method. The subsequent annealing step promoted the conversion of N-containing species from pyrrolic N to pyridinic N, leading to a remarkably improvement of electrochemical performance towards the oxygen reduction reaction. The theoretical simulations indicated that the rapid H transfer and thermodynamic stability of six-membered N structure boost the transformation of N-containing species.

An approach to construct nanorattles based on upconverting lanthanide-doped fluorides

We developed a novel “ship-in-a-bottle” method to fabricate upconverting (UC) luminescent nanorattles by incorporating lanthanide-doped fluorides into hollow mesoporous silica. Furthermore, we employed these nanorattles in proof-of-concept UC-monitoring drug release by utilizing the energy transfer process from UC fluorides to DOX, thus revealing the great potential of the nanorattles as efficient cancer theranostic agent.

Porous spinel cobalt manganese oxides as efficient oxygen reduction reaction electrocatalysts

Three type of spinel CoxMn3-xO4 (CMOs), cubic Co2MnO4 nanorods, tetragonal CoMn2O4 microspheres, and tetragonal CoMn2O4 cubes, were successfully obtained and exhibit brilliant oxygen reduction reaction (ORR) electrocatalysis along with high stability. In particular, the cubic Co2MnO4 nanorods show the best performance with an onset potential of 0.9 V and a half-wave potential of 0.72 V and superior stability after a continuous operation time of 10,000 seconds.

Vertically stacked holey graphene/polyaniline heterostructures with enhanced energy storage for on-chip micro-supercapacitors

Micro-supercapacitors with holey graphene/polyaniline heterostructures were successfully designed and constructed. The capacitance and rate capability of micro-supercapacitors can be improved largely by introducing the holy graphene intermediate layer. This improvement is mainly due to the unique structure of holy graphene, which not only increases the electrical transport of electrodes, but also results in three-dimensional transport for electrolyte ions. Highly efficient energy storage is, thus, realized.

According to a pair of studies, simultaneous inhibition of angiopoietin-2 (Ang-2) and the vascular endothelial growth factor (VEGF) pathway in mouse models of glioblastoma was associated with slowed tumor growth, enhanced blood vessel normalization, and extended survival compared with either Ang-2 or VEGF inhibition alone, and the combination therapy was also associated with an increased fraction of tumor-associated macrophages that exhibited an anti-tumor phenotype.
