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.

In the process of their formation, northern peatlands were accumulating vast amounts of carbon (C). When drained for agricultural use, a large proportion of that C is oxidized and emitted as carbon dioxide (CO 2 ), turning those peatlands…
Eric R Simon, Alysan Mallery, John Silva et al. · 2025 · Regional Anesthesia & Pain Medicine
Background Acute pain after cardiac surgery via median sternotomy is commonly managed with multimodal analgesia, but optimal regional techniques remain uncertain. Superficial parasternal intercostal plane (SPIP) blocks have shown promise…
