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.

Franco VR, Lima-Costa AR, Araujo BB et al. · 2025 · Preprint
Traditionally, extreme responding has been recognized as a bias in which individuals tend to select the highest or lowest response categories on self-report items, regardless of item content. This bias is believed to occur independently of…
Armand M, Zeilmann L, Weinzettl C et al. · 2025 · Preprint
Abstract To attract pollinators, flowering plants evolve diverse sensory traits into compelling signals. Floral scent, in particular, plays a key role in drawing bees from a distance and shaping their foraging choices. Scent composition…

Introduction Indomethacin is often used experimentally to induce intestinal hyperpermeability, enabling evaluation of interventions targeting barrier function. Methods We conducted a randomized, double-blind, placebo-controlled study…
Wimmer GE, Liang S · 2025 · Preprint
Impairments in reward-related behavior in everyday life are characteristic of major depressive disorder and closely linked with anhedonia. While previous research has suggested a negative relationship between reward-related behavior and…
Birt HWG, Allen LP, Madge S et al. · 2025 · Preprint
Abstract Most plants extend their zone of interaction with surrounding soils and plants via mycorrhizal hyphae, which in some cases can form common mycorrhizal networks with hyphal continuity to other radial plants. These interactions can…

Research has shown that affective visual and auditory events (e.g., a crying baby) are perceived as lasting longer compared to neutral ones. However, the impact of affective haptic experiences on time perception has hardly been studied.…
Williams EP, Harris LN, Moore JS et al. · 2025 · Journal of fish biology
Many Arctic fishes experience prolonged periods of extreme cold and large thermal variation over both rapid and seasonal time scales which challenge critical physiological functions. In the central Canadian Arctic, we caught wild adult…
