High Voltage DC Active Current Injection to Simulate Geomagnetically Induced Currents in New Zealand

open access: yesSpace Weather, Volume 24, Issue 3, March 2026.
Abstract This study investigates the effects of geomagnetically induced currents (GIC) on New Zealand's electrical infrastructure via an intentional ground injection of direct current (DC) from a high voltage DC converter station. GIC manifests as quasi‐DC currents within power systems, potentially causing transformer saturation, increased reactive ...

Climate Change, Air Quality, and Pollen Allergies—State of the Art and Recommendations for Research and Public Health

open access: yesAllergy, Volume 81, Issue 3, Page 663-683, March 2026.
ABSTRACT Allergies are one of the major health challenges of our time, associated with a high individual burden of disease and high costs for the healthcare system. Given their prevalence, allergies are also highly relevant from a public health perspective. The development of allergic diseases is multifactorial. In addition to individual factors (e.g.,
