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.

Gallic acid, a catechin polyphenol in tea, completely inhibited angiogenesis in assays of human tissue at 10 -3 M. Psoriasis is a skin disease caused by excessive secretion of angiogenenic factors by keratinocytes and stromal skin cells.…
Fantasia ME, Penick CA · 2026 · Journal of economic entomology
Climate change intensifies drought frequency, posing risks to pollinators both directly and indirectly through changes in floral resource availability. We tested how water limitation alters pollinator-relevant floral traits, visitation,…
Kasige RH, Johnson SN, Frew A · 2026 · Preprint
Abstract Background and aims. Plant susceptibility to insect herbivores is shaped by interacting soil-based biotic and abiotic factors, particularly arbuscular mycorrhizal (AM) fungi and silicon (Si) availability. AM fungi influence plant…
Ge H, Calero C, Costas R · 2026 · Preprint
Abstract Global scientific mobility is central to the circulation of knowledge, skills and opportunities, but its recent evolution remains unclear. Using the Dimensions database, we reconstruct publication-based career trajectories for…
