Elevated CO alters soybean physiology and defense responses, and has disparate effects on susceptibility to diverse microbial pathogens.

Increasing atmospheric CO levels have a variety of effects that can influence plant responses to microbial pathogens. However, these responses are varied, and it is challenging to predict how elevated CO (eCO) will affect a particular plant-pathogen interaction. We investigated how eCO may influence disease development and responses to diverse pathogens in the major oilseed crop, soybean.

Interactions between phosphate and arsenic in iron/biochar-treated groundwater: Corrosion control insights from column experiments.

An increasing number of studies have reported the coexistence of arsenic (As) and phosphorus at high concentrations in groundwater, which threatens human health and increases the complexity of groundwater remediation. However, limited work has been done regarding As interception in the presence of phosphate in flowing systems. In this study, a series of experiments were conducted to evaluate the interactions between phosphate and As during As removal by iron (Fe)-based biochar (FeBC).

How to encourage well-being with reminders interventions: A field experiment on food waste separation and composting behaviors.

Although well-being is a fundamental human goal, few studies have clarified the causal relationship between well-being and waste separation, which strongly affects sustainable development. We propose that, assuming humans' innate affinity for nature (the biophilia theory), waste separation would be conducive to a sense of life meaning and well-being. To test this hypothesis, we systematically investigate how food waste separation and composting behaviors affect subjective well-being and meaning in life in a longitudinal field experiment.

Soliton and rogue wave excitations in the Chen-Lee-Liu derivative nonlinear Schrödinger equation with two complex PT-symmetric potentials.

We demonstrate that fundamental nonlinear localized modes can exist in the Chen-Lee-Liu equation modified by several parity-time (PT) symmetric complex potentials. The explicit formula of analytical solitons is derived from the physically interesting Scarf-II potential, and families of spatial solitons in internal modes are numerically captured under the optical lattice potential. By the spectral analysis of linear stability, we observe that these bright solitons can remain stable across a broad scope of potential parameters, despite the breaking of the corresponding linear PT-symmetric phases.

Longitudinal changes in cerebral metabolic rate of oxygen in older adults without and with cognitive impairment.

Background: Cerebral metabolic rate of oxygen (CMRO) denotes the amount of O that the brain consumes. Changes in CMRO during aging and neurodegeneration have not been fully characterized. Using a non‐invasive, non‐contrast MRI CMRO technique, the present study reports CMRO changes in older adults from a total of 526 measurements, the largest CMRO dataset to date.
