Pre-existing condition : taking media coverage into account when preparing for H1N1 [PDF]

open access: yes, 2016
This paper examines the claim that media exaggerated the threat of H1N1, prompting an immediate demand for limited vaccine. We compare the Australian’s and the Daily Telegraph’s (UK) coverage of H1N1 with the coverage in the Globe and Mail, which is ...

A Cold Stress‐Activated Endocrine Sentinel Chemical Hormone Promotes Insect Survival via Mitochondrial Adaptations Through the Adipokinetic Hormone Receptor

open access: yesAdvanced Science, EarlyView.
Seasonal cold adaptation is vital for insect survival, yet the molecular mechanisms linking diapause to mitochondrial resilience remain largely unresolved. We identify ascaroside C9 (asc‐C9) as a key endocrine signal that enhances diapause survival during cold stress by activating the AKHR–PGC1α–UCP4 axis, thereby driving cold‐induced lipolysis and ...

Background discrimination with a Micromegas detector prototype and veto system for BabyIAXO

open access: yesFrontiers in Physics
In this paper we present measurements performed with a Micromegas X-ray detector setup. The detector is a prototype in the context of the BabyIAXO helioscope, which is under construction to search for an emission of the hypothetical axion particle from ...

Aqueous Supercapacitor with Wide‐Temperature Operability and over 100,000 Cycles Enabled by Water‐in‐Salt Electrolyte

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
This study presents a symmetric supercapacitor with activated carbon electrodes and a “water‐in‐salt” electrolyte (WiSE) based on lithium perchlorate, offering over 100,000 cycles with over 90 % capacity retention. The supercapacitor operates efficiently from −20 to 80 °C, enhancing performance, stability, and all‐season operability.
