Multifeature analyses of vascular cambial cells reveal longevity mechanisms in old Ginkgo biloba trees
This article investigates age-related changes in Ginkgo biloba trees to learn more about the molecular and metabolic mechanisms underlying their longevity. The results revealed that long-lived trees have evolved compensatory mechanisms to maintain a balance between growth and aging processes.

Liquid Chromatography Tandem Mass Spectrometry Quantification of ¹³C-Labeling in Sugars
This article describes a new methodology for monitoring sucrose labeling using liquid chromatography tandem mass spectrometry (LC-MS/MS). To date, the most commonly used method to monitor sucrose labeling is by nuclear magnetic resonance, which requires substantial amounts of biological sample.

Prioritizing riparian corridors for ecosystem restoration in urbanizing watersheds
This article explores restoration, rather than protection, being the basis for developing a watershed level strategy for improving water quality in urbanizing watersheds.This study uses a geographical information system (GIS) approach that utilizes riparian characteristics extracted from 40-meter wide corridors centered on streams and rivers. The model was applied to 90 sub-watersheds in the watershed of an important drinking water reservoir in north central Texas, USA.

West Nile Virus risk and susceptibility in central California modeling dataset
The dataset was developed to support research intended to develop a spatially explicit model that explores environmental data related to the risk of exposure to West Nile Virus (WNV), and the susceptibility to WNV disease based on demographic data of the potentially affected population. The model was developed and then tested on census tracts in an identified hot spot of WNV in central California. The dataset contains (1) U.S. Census Bureau 2010 demographic data for 1,133 census tracks in the hotspot, and (2) and average mosquito habitat risk data for each of those census tracks.

Sub-Antarctic Freshwater Invertebrate Thermal Tolerances: An Assessment of Critical Thermal Limits and Behavioral Responses
Describes study which assessed the upper (CTmax) and lower (CTmin) thermal limits of three freshwater macroinvertebrate taxa with restricted low elevation distribution (20 m a.s.l.) and three taxa restricted to upper elevations (480 and 700 m a.s.l.) in the Magellanic sub-Antarctic ecoregion of southern Chile, and argues that their low tolerance to temperature increase can make them useful as indicators of thermal alteration in their habitats.

Underlying Ossification Phenotype in a Murine Model of Metastatic Synovial Sarcoma
This article presents the analysis of genetic mouse models of synovial sarcoma to determine the extent of ossification in the tumors and its relationship with morbidity. The authors noted higher ossification within their metastatic mouse model of synovial sarcoma. Their conclusion is that both metastasis and ossification are dependent on time, but that they are independent of one another.

Development of a Thulium Fiber Laser for an Atomic Spectroscopy Experiment
This article is a simplified analysis of a convenient thulium fiber laser source with 3 W of output power operating at a wavelength of 2059 nm with a slope efficiency of 49% with respect to input pump power and 60% with respect to absorbed pump power. The laser was applied in an atomic helium spectroscopy experiment to quench ³He (2058.63 nm) and ⁴He (2058.69 nm) meta-stable singlets (2¹S0), allowing for further investigation of the helium fine structure.

Exploring NIR Aza-BODIPY-Based Polarity Sensitive Probes with ON-and-OFF Fluorescence Switching in Pluronic Nanoparticles
The articles is about a study of the response of six NIR aza-BODIPY-based and structurally similar fluorophores to polarity and viscosity for incorporation inside Pluronic nanoparticles as switchable fluorescent probes (SFPs). Based on their results, all of these fluorophores were moderately to strongly sensitive to the polarity of the microenvironment. They concluded that attaching amine groups to the fluorophore is not necessary for having strong polarity sensitive probes.

High-Throughput Computational Search for Half-Metallic Oxides
The article describes a high-throughput computational search for half-metallic compounds. The analysis of calculated electronic properties of thousands of materials from the inorganic crystal structure database allowed the authors to identify potential half metals. They found over two-hundred strong half-metallic oxides; several of them have never been reported before.
