A searchable index of real negative results, null findings, and replication failures from the published literature — so you can learn what didn't work before repeating it.
WASTE indexes published research — it does not host or republish full papers. Each entry is a metadata record (title, authors, DOI) compiled from open scholarly databases, with the abstract shown in full only where the paper is openly licensed (e.g. Creative Commons); otherwise a short excerpt is shown for reference under fair use. WASTE classifies each work by failure type; classifications are automated and approximate.

Few studies have comprehensively assessed the forage nutrition quality and pools among different plant functional groups across various grassland types and management practices. Moreover, the relationship between forage yield and nutrition…
Pacioni C, Verheyen K, Martel A et al. · 2025 · Preprint
Increasing forest structural complexity is a key objective of future-proof forest management, with potential benefits for biodiversity. However, empirical evidence for consistent biodiversity-structure relationships across taxa is still…
Ha M, Doan X · 2025 · Preprint
Abstract Drawing on the theories of natural-resource-based view and social cognition, this research examines the influence of green intellectual capital (GIC) on environmental performance (EP) and analyses the mediation roles of…
Häring M, Zhang Y, Zhang N et al. · 2026 · Biophysical journal
Cell junction remodeling is central to epithelial morphogenesis and tissue rheology and depends on the interplay between adhesion molecules and the actomyosin cortex. E-cadherin constitutes the molecular basis for epithelial cell adhesion,…

Food choices profoundly impact population health and the environment. Related research often relies on self-reported data, which is prone to biases, compromising the accuracy and validity of conclusions about consumer behavior. There are…
Qian Y, Liu M, Zhu L · 2025 · Preprint
Abstract Feedback is a vital but often difficult part of introductory programming courses, where standard compiler messages are vague and confusing for students. Generative artificial intelligence (GenAI) has become a promising tool for…
Hanselmann S, Grossmann K, Weideli OC et al. · 2025 · Preprint
Abstract Background Foehn winds—warm, dry downslope winds common in alpine regions—may impact human health, especially in weather-sensitive individuals, though evidence is lacking. Wearable devices now enable continuous health monitoring,…
Kuşkaya S, Bilgili F · 2025 · Preprint
Abstract An accurate forecast of stock market indices is a cornerstone of financial decision-making. This study employs a range of machine learning models to forecast the daily closing price of the Dow Jones Australia Index (DJ Australia)…
Dantas TAV, Dantas A, Ganade G et al. · 2025 · Oecologia
Plant biodiversity can influence the structure of other trophic levels, with cascading effects on ecosystem functioning. Biodiversity-ecosystem function (BEF) experiments that manipulate tree diversity provide information on the mechanisms…
Palacios-Lagunas DA, Hernández-Mondragón JC, Fuxe K et al. · 2026 · Pharmacology, biochemistry, and behavior
The promotion of prosocial behavior is a remarkable MDMA property. Such an effect is rather uncommon among other psychoactive substances and has been proposed to be of relevance for the potential therapeutic utility of MDMA. We aim to…
