Guidelines for Sample Preparation and Stable Isotope Analysis of Food for Traceability Studies

Food Safety and Health, EarlyView.
This workflow illustrates sample preparation and analysis steps in stable isotope ratio mass spectrometer (IRMS) for food traceability. It emphasizes standardized preparation, encapsulation, calibration, and quality control to ensure accurate, comparable isotope data critical for verifying food origin and authenticity across complex supply chains ...

A local meteoric water line for interior Alaska constrains paleoclimate from 40 000 year old relict permafrost

Environmental Research Letters
Anthropogenic climate warming is degrading permafrost across interior Alaska. Information from past warming events provides long-term perspectives for future trajectories; however, late Quaternary seasonal temperatures are poorly constrained.

Almond (Amygdalus communis L.) Peptides Improve Scopolamine‐Induced Learning and Memory Impairment in Mice

Food Safety and Health, EarlyView.
Figure Schematic showing the improvement of almond peptides on learning and memory impairment induced by scopolamine in mice. Almond peptides (APs) could improve the learning and memory in scopolamine‐induced mice by maintaining cholinergic system homeostasis and regulating Nrf2/Keap1 signaling pathway, via activating the Nrf2 transcription factor and ...

Joint inversion estimate of regional glacial isostatic adjustment in Antarctica considering a lateral varying Earth structure (ESA STSE Project REGINA) [PDF]

, 2017
A major uncertainty in determining the mass balance of the Antarctic ice sheet from measurements of satellite gravimetry, and to a lesser extent satellite altimetry, is the poorly known correction for the ongoing deformation of the solid Earth caused by

Marine Macroalgae as a Safe Healthy Food While Meeting Food Security Challenges Arising From Climate Changes

Food Safety and Health, EarlyView.
Planned harvesting and processing of marine macroalgae could meet future global food needs and mitigate fuel‐originated carbon dioxide responsible for climate change. Microalgal foods are nutritious and safe. The utilization of macroalgae would avoid environmental problems arising from the release of overgrowing macroalgae caused by heatwaves, which ...

Potential climatic transitions with profound impact on Europe [PDF]

, 2011
We discuss potential transitions of six climatic subsystems with large-scale impact on Europe, sometimes denoted as tipping elements. These are the ice sheets on Greenland and West Antarctica, the Atlantic thermohaline circulation, Arctic sea ice, Alpine

Heat and Cold Waves in Brazil: An ERA5‐Based Analysis of Trends and Seasonality (1980–2024)

International Journal of Climatology, EarlyView.
This study uses ERA5 reanalysis data to assess changes in extreme heat and cold events across Brazil from 1980 to 2024. Results reveal a sharp increase in heatwave frequency and a general decline in coldwave occurrences, though regional variations are substantial.

An assessment of the spatial extent of polar dust using satellite thermal data

Scientific Reports, 2021
The effect of mineral dust aerosols and subsequent deposition in polar regions has historically been underestimated in climate models. Dust aerosols increase melt rates by reducing surface albedo and modifying atmospheric radiative properties.

Antarctic climate, Southern Ocean circulation patterns, and deep water formation during the Eocene [PDF]

, 2017
We assess early-to-middle Eocene seawater neodymium (Nd) isotope records from seven Southern Ocean deep-sea drill sites to evaluate the role of Southern Ocean circulation in long-term Cenozoic climate change.
