The Ecology of Human Sleep (EcoSleep) Cohort Study: Protocol for a longitudinal repeated measurement burst design study to assess the relationship between sleep determinants and outcomes under real‐world conditions across time of year

open access: yesJournal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary The interplay of daily life factors, including mood, physical activity, or light exposure, influences sleep architecture and quality. Laboratory‐based studies often isolate these determinants to establish causality, thereby sacrificing ecological validity.

Investigating the Combined Effect of Artificial Light at Night and Noise on Sleep Quality of High School Students

open access: yesJournal of Sleep Research, EarlyView.
Adolescents today are heavily exposed to ALAN from different sources, including cellular phones, personal computers, tablets, as well as other indoor and outdoor light sources, which affects the quality of their sleep. ABSTRACT Adolescents frequently use smartphones, smartwatches, personal computers, tablets, and other electronic devices during the day

The Influence of Light and Physical Activity on the Timing and Duration of Sleep: Insights from a Natural Model of Dance Training in Shifts

open access: yesClocks & Sleep, 2023
Environmental, social, and behavioral variables influence sleep timing and duration. Using wrist-worn accelerometers, we recorded 31 dancers (age = 22.6 ± 3.5) for 17 days and who trained either in the morning (n = 15) or in the late evening (n = 16). We

Organ‐specific terpenoid responses in Tanacetum vulgare are chemotype‐dependent

open access: yesPlant Biology, EarlyView.
Common tansy varieties defend differently: some boost root chemicals against soil pests, while others release stronger leaf scents against aphids. Abstract Specialized metabolites such as terpenoids are known to mediate plant defence mechanisms. However, how terpenoid diversity governs inducible chemistry across organs remains poorly understood.

Characterization of Grape Cane Stilbenoids and Their Photo‐Degradation Products by HPLC‐DAD Coupled With Trapped Ion Mobility Spectrometry and High‐Resolution Tandem Mass Spectrometry

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 15, 15 August 2026.
ABSTRACT Rationale Bioactive (E)‐stilbenoids in vine extracts are prone to light‐induced transformation into the respective (Z)‐isomers and further degradation products, often resulting in a loss of bioactivity. We sought to study stilbenoid degradation beyond that of the well‐researched resveratrol due to the high diversity of stilbenoids in nature ...

Carbon Stock and Environmental Variations of Typical Plantations in Mufu Mountain in Hubei Province, China

open access: yesLand Degradation &Development, Volume 37, Issue 9, Page 3715-3725, 30 May 2026.
ABSTRACT Forest ecosystems play a critical role in the global carbon cycle. As a significant terrestrial carbon sink, plantations exhibit carbon stock patterns that are shaped by tree species composition, stand structure, and environmental conditions. Here, we investigated typical plantation types in the Mufu Mountain, Hubei Province.
