Searching for effects caused by thunderstorms in midlatitude sporadic E layers [PDF]

, 2017
Possible thunderstorm - sporadic E (Es) layer coupling effects are investigated during two measurement periods, one in 2013 and one in 2014. The analysis was based on ionospheric observations obtained from a Digisonde at Pruhonice, the Czech Republic, an

Hell's Itch: An Acute Reaction to Sunburn Exposure

JEADV Clinical Practice, EarlyView.
ABSTRACT Hell's itch is a neurocutaneous dysesthesia following sunburn that is underreported in scientific literature despite considerable discussion online. ‘Hell's itch’ describes an acute, uncontrollable itch with intense stabbing pain several days post‐sunburn and often follows an inciting event such as water exposure.

Detecting and attributing climate change effects on vegetation: Australia as a test case

PLANTS, PEOPLE, PLANET, EarlyView.
Climate change is contributing to vegetation changes that threaten life support systems. Yet, inherent climatic variability and past and present human actions—such as clearing, burning and grazing regimes—also alter vegetation and complicate understanding of vegetation change. Australian ecosystems exemplify such complexity.
