Failure-mode index

Search what already failed

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.

Optimal medical care and coronary flow capacity-guided myocardial revascularization vs usual care for chronic coronary artery disease: the CENTURY trial

K. Lance Gould, Nils P. Johnson, Amanda E. Roby et al. · 2025 · European Heart Journal

BACKGROUND AND AIMS: The randomized CENTURY trial tested the hypothesis that a comprehensive strategy integrating intense lifestyle modification and aggressive medical management to goals with revascularization reserved for severely reduced coronary flow capacity (CFC) by positron emission tomography (PET) would reduce risk factors, subsequent revascularization, death and myocardial infarction (MI) compared with standard of care in chronic stable coronary artery disease (CAD). METHODS: Participants were randomly assigned to standard or comprehensive care groups. Rest-stress PET quantified CFC

Nobel Glas · 2026 · Zenodo (CERN European Organization for Nuclear Research)

EA-GLAS-02 v1.0. A self-contained empirical white paper presenting the measurement program for the Semantic Deviation Principle (Sharks 2026). Defines meaning as the time-integrated divergence a sign induces from the most probable trajectory of a semantic field, extending the Bar-Hillel and Carnap (1953) program into distributional and temporal domains. Two primary operationalizations. (F1) Closed-system trajectory deviation within a frozen language model, where the counterfactual baseline is read from logits, building on surprisal theory (Hale 2001; Levy 2008) and decomposing it into signed d

Resolution limit of the eye — how many pixels can we see?

Maliha Ashraf, Alexandre Chapiro, Rafał Mantiuk · 2025 · Nature Communications

As large engineering efforts go towards improving the resolution of mobile, augmented reality (AR), and virtual reality (VR) displays, it is important to know the maximum resolution at which further improvements bring no noticeable benefit. This limit is often referred to as the retinal resolution, although the limiting factor may not necessarily be attributed to the retina. To determine the ultimate resolution at which an image appears sharp to our eyes with no perceivable blur, we created an experimental setup with a sliding display, which allows for continuous control of the resolution. The

SΔϕ-60 — Utilitarian Subject-Splitting Index

Sofience · 2026 · Zenodo (CERN European Organization for Nuclear Research)

SΔϕ-60 introduces the Utilitarian Subject-Splitting Index, USSI, within the Sofience-Δϕ Formalism. The paper examines whether utilitarian calculation merely evaluates the happiness of already-existing majorities and minorities, or whether such calculation can first produce the operational boundary between majority and minority by redistributing Transition Completion Cost, TCC. The document begins with the Sofience Subject Thought Experiment. A person is imagined as capable of detaching and reattaching any part of the body while the detached parts remain alive, neurologically connected, and phy

Rapid Integration of LLMs in Healthcare Raises Ethical Concerns: An Investigation into Deceptive Patterns in Social Robots

Robert Ranisch, Joschka Haltaufderheide · 2025 · Digital Society

Abstract Conversational agents are increasingly used in healthcare, with Large Language Models (LLMs) significantly enhancing their capabilities. When integrated into social robots, LLMs offer the potential for more natural interactions. However, while LLMs promise numerous benefits, they also raise critical ethical concerns, particularly regarding hallucinations and deceptive patterns. In this case study, we observed a critical pattern of deceptive behavior in commercially available LLM-based care software integrated into robots. The LLM-equipped robot falsely claimed to have medication remin

Microbiome modulation of tumorigenesis and immune responses

Yuning Chen, Ying Fang, Zibai Lyu et al. · 2026 · Journal of Biomedical Science

The microbiome has emerged as a critical, context-dependent regulator of tumorigenesis and anticancer immunity, capable of either promoting cancer progression or protecting against malignancy. This dual role is mediated by multiple interconnected mechanisms-including chronic inflammation, modulation of immune responses, and alterations in host metabolic signaling. These microbiome-cancer interactions vary across organs, influencing malignancies in the colon, breast, lung, and beyond. Clinically, the microbiome significantly affects patient responses to cancer therapies, particularly immunother

Cathepsins in Neurological Diseases

Dominik Lewandowski, Mateusz Konieczny, Agata Różycka et al. · 2025 · International Journal of Molecular Sciences

Cathepsins, a family of lysosomal proteases, play critical roles in maintaining cellular homeostasis through protein degradation and modulation of immune responses. In the central nervous system (CNS), their functions extend beyond classical proteolysis, influencing neuroinflammation, synaptic remodeling, and neurodegeneration. Emerging evidence underscores the crucial role of microglial cathepsins in the pathophysiology of several neurological disorders. This review synthesizes current knowledge on the involvement of cathepsins in a spectrum of CNS diseases, including Parkinson's disease, Alz
