Life expectancy of Danish women

The recent rise in Danish women's life expectancy can be largely attributed to the high mortality of Danish women who were born during 1915-1945, a study reports.

Megacities and seasonal outbreaks of infectious disease

A study examines links between climate and infectious disease transmission dynamics in different zones of a megacity. In regions with an annual monsoon, the onset of rainy weather is often followed by spikes in diseases such as cholera and leptospirosis.

Ultrathin CoNi double hydroxide/CoO nanosheets synthesized via interface-directed assembly

CoNi LDH/CoO nanosheets, assembled with CoNi LDH and small-sized CoO nanocrystals,has been synthesized. An enhancement in the OER performance is associated with: high-valence Co and Ni acting as catalysis centers; numerous exposed defects and excellent durability derived from the weak crystallinity; increase in OH−/O2 adsorption and transport within the loose and porous structure. In situ reduction and interface-directed assembly is an effective route to the preparation of other LDHs, oxides, and metal nanosheets with transition-metals

Mediterranean diet associated with small reduction in risk of hip fracture

Eating a Mediterranean diet full of fruits, vegetables, fish, nuts, legumes and whole grains appears to be associated with a lower risk of hip fracture in women, although the actual risk reduction was small, according to a new study published online by JAMA Internal Medicine.

Self-delivery of a peptide-based prodrug for tumor-targeting therapy

In our study, we have reported a novel RGD-mediated self-deliverable prodrug for tumor therapy. The prodrug self-assembled into nanofibers, which sequestered active CPT molecules within the hydrophobic cores and therefore ensured their bioactivity. RGD groups on the surface of nanofibers indexed the prodrug into tumor tissues/cells, and effectively inhibited tumor growth.

Growth and in situ transformation of TiO2 and HTiOF3 crystals on chitosan-polyvinyl alcohol co-polymer substrates under vapor phase hydrothermal conditions

A chitosan-polyvinyl alcohol co-polymer with rich amino and hydroxyl groups are used as the substrate to induce direct growth and in situ sequential transformation of titanate crystals under HF vapor phase hydrothermal conditions. The demonstrated substrate organic functional groups induced crystal formation/transformation approach could be applicable to other material systems.

Tolerance to daily versus seasonal temperature changes may dictate fitness

While it’s theorized that vertebrates adapted to endure greater swings in seasonal temperatures tend to have greater elevational ranges, this pattern is reversed in species that are adapted for high daily temperature fluctuations, a new study suggests.

Multilayer ReSe2/MoS2 p–n heterojunctions

We reported vertical heterojunctions based on multilayer exfoliated n-type hexagonal-structure MoS2 and p-type distorted CdCl2-structure ReSe2 nanoflakes. The (opto)electronics based on such heterojunctions are experimentally confirmed to possess preferable functionalities to single component ReSe2 or MoS2 devices, including obvious rectification, elevated electron mobility and on/off current ratio, and efficient photocurrent generation. The Vienna ab initio simulation package was employed to give a standard p–n junction arrangement for the ReSe2/MoS2 heterojunctions.

Theoretical study on two-dimensional MoS2 piezoelectric nanogenerators

This study employs the finite-element-method to examine the output characteristics of the two-dimensional MoS2 piezoelectric nanogenerator. Due to lack of center symmetry, the MoS2 flakes with odd number of atomic layers are capable of giving obvious piezoelectric output, which decreases upon the increases of the layer number. In addition, since the MoS2 nanogenerators are only few-atoms thick, they have smaller capacitance than the nanowire/film based nanogenerators, which enable them for potential high-frequency applications.

Pressure balance and imbalance in the optic nerve chamber

Glaucomatous optic neuropathy that damages the retina or optic nerve may be a pathological response to altered physiological pressure gradients created by both intraocular pressure (IOP) and intracranial pressure (ICP). A recent study was conducted to investigate the interdependence of ICP and IOP and how it affects optic nerve pressures.

The dendritic platinum-copper bimetallic nanoassemblies with tunable composition and structure

This work takes advantage of the unique coordination and self-assembly properties of arginine for fabricating dendritic PtCu bimetallic nanoassemblies with tunable chemical composition and structure. Thanks to the unique dendritic structure and synergetic effect between Pt and Cu atoms, the Pt3Cu1 nanoassemblies exhibit improved electrocatalytic activity and stability in comparison with the Pt1Cu3, Pt1Cu1 nanoassemblies and commercial Pt black.

According to a study, analysis of more than 2,500 human genome sequences from the 1000 Genomes Project and Human Genome Diversity Project databases revealed 19 previously unidentified endogenous retroviruses, one of which appears to lack mutations that would compromise viral gene function, suggesting the latent potential of the virus for activation.
