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.

Researchers and software developers require effective performance evaluation. Researchers must evaluate optimizations or measure overhead. Software developers use automatic performance regression tests to discover when changes improve or…
Gillianne Bowman, Thierry Huber, Vanessa Burg · 2023 · Energies
Today, an energy transition is underway to tackle the problems of climate change and energy sufficiency. For this transition to succeed, it is essential to use all available renewable energy resources most efficiently. However, renewable…
