Ocean microbes team up brilliantly to gather food when it's scarce
(Marine Biological Laboratory) What's a hungry marine microbe to do when the pickings are slim? It must capture nutrients - nitrogen, phosphorus, or iron - to survive, yet in vast expanses of the ocean, nutrients are extremely scarce. One ingenious solution to this challenge is reported this week in Proceedings of the National Academy of Sciences. (Source: EurekAlert! - Biology)

Metagenomic analysis reveals global-scale patterns of ocean nutrient limitation
Nutrient supply regulates the activity of phytoplankton, but the global biogeography of nutrient limitation and co-limitation is poorly understood. Prochlorococcus adapt to local environments by gene gains and losses, and we used genomic changes as an indicator of adaptation to nutrient stress. We collected metagenomes from all major ocean regions as part of the Global Ocean Ship-based Hydrographic Investigations Program (Bio-GO-SHIP) and quantified shifts in genes involved in nitrogen, phosphorus, and iron assimilation. We found regional transitions in stress type and severity as well as widespread co-stress. Prochlorococ...

For highly active, sustainable catalysts, just add phosphorus
(Osaka University) Osaka University researchers have developed a single-crystal cobalt phosphide nanorod catalyst for the reductive amination of carbonyl compounds to primary amines. The nanorod catalyst performed better than conventional catalysts, was stable in air, and was effective under mild conditions. Additionally, it could be reused multiple times without loss of activity. It is hoped that the nanorod catalyst will provide a green and sustainable alternative for the synthesis of valuable products such as pharmaceuticals. (Source: EurekAlert! - Biology)

A van der Waals interface that creates in-plane polarization and a spontaneous photovoltaic effect
Van der Waals interfaces can be formed by layer stacking without regard to lattice constants or symmetries of individual building blocks. We engineered the symmetry of a van der Waals interface of tungsten selenide and black phosphorus and realized in-plane electronic polarization that led to the emergence of a spontaneous photovoltaic effect. Spontaneous photocurrent was observed along the polar direction and was absent in the direction perpendicular to it. The observed spontaneous photocurrent was explained by a quantum-mechanical shift current that reflects the geometrical and topological electronic nature of this emerg...

Menarche usually occurs within 2 years of breast budding occurring usually at Tanner stage III-IV breast development. Menarche occurs for most girls from 10-15 years. Most cycles range between 21-45 days. Age> 13 years without acquisition of secondary sexual characteristics,> 15 years before menarche or 5 years after acquisition of secondary sexual characteristics or cycles longer than 45 days are indications for evaluation.

Redox-active antibiotics enhance phosphorus bioavailability
In this study, we explore long-standing observations that microbes increase the production of redox-active antibiotics under phosphorus limitation. The availability of phosphorus, a nutrient required by all life on Earth and essential for agriculture, can be controlled by adsorption to and release from iron minerals by means of redox cycling. Using phenazine antibiotic production by pseudomonads as a case study, we show that phenazines are regulated by phosphorus, solubilize phosphorus through reductive dissolution of iron oxides in the lab and field, and increase phosphorus-limited microbial growth. Phenazines are just on...

Black phosphorus composites with engineered interfaces for high-rate high-capacity lithium storage
We report use of black phosphorus (BP) as the active anode for high-rate, high-capacity Li storage. The formation of covalent bonds with graphitic carbon restrains edge reconstruction in layered BP particles to ensure open edges for fast Li+ entry; the coating of the covalently bonded BP-graphite particles with electrolyte-swollen polyaniline yields a stable solid–electrolyte interphase and inhibits the continuous growth of poorly conducting Li fluorides and carbonates to ensure efficient Li+ transport. The resultant composite anode demonstrates an excellent combination of capacity, rate, and cycling endurance. (Source: ScienceNOW)
