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.

Rodent Models of Alzheimer’s Disease: Past Misconceptions and Future Prospects

Helen M Collins, Susan A. Greenfield · 2024 · International Journal of Molecular Sciences

Alzheimer's disease (AD) is a progressive neurodegenerative disease with no effective treatments, not least due to the lack of authentic animal models. Typically, rodent models recapitulate the effects but not causes of AD, such as cholinergic neuron loss: lesioning of cholinergic neurons mimics the cognitive decline reminiscent of AD but not its neuropathology. Alternative models rely on the overexpression of genes associated with familial AD, such as amyloid precursor protein, or have genetically amplified expression of mutant tau. Yet transgenic rodent models poorly replicate the neuropatho

Testing the Magnitude of Correlations Across Experimental Conditions

Simone Di Plinio · 2022 · Frontiers in Psychology

Correlation coefficients are often compared to investigate data across multiple research fields, as they allow investigators to determine different degrees of correlation to independent variables. Even with adequate sample size, such differences may be minor but still scientifically relevant. To date, although much effort has gone into developing methods for estimating differences across correlation coefficients, adequate tools for variable sample sizes and correlational strengths have yet to be tested. The present study evaluated four different methods for detecting the difference between two

FMR1, circadian genes and depression: suggestive associations or false discovery?

Daniel F. Kripke, Caroline M. Nievergelt, Gregory J. Tranah et al. · 2013 · Journal of Circadian Rhythms

BACKGROUND: There are several indications that malfunctions of the circadian clock contribute to depression. To search for particular circadian gene polymorphisms associated with depression, diverse polymorphisms were genotyped in two samples covering a range of depressed volunteers and participants with normal mood. METHODS: Depression mood self-ratings and DNA were collected independently from a sample of patients presenting to a sleep disorders center (1086 of European origin) and from a separate sample consisting of 399 participants claiming delayed sleep phase symptoms and 406 partly-matc

Shedding light on relations between teacher emotions, instructional behavior, and student school well-being – Evidence from disadvantaged schools

Julia Holzer, Luisa Grützmacher, Marko Lüftenegger et al. · 2024 · Learning and Instruction

Despite broad theoretical consensus on the direct and indirect relevance of teacher emotions for instructional behavior and student outcomes, empirical evidence is inconclusive. Moreover, there is limited research in this area involving disadvantaged and younger student populations, and addressing students’ school well-being as an outcome explicitly. This study investigates associations between teacher emotions (joy, anger, anxiety), teacher-reports of instructional behavior (cognitive and motivational stimulation, classroom management, and social support), and students' reported school well-b

Functional evaluation of a real-time EMG controlled prosthetic hand

Amlan Jyoti Kalita, Maibam Pooya Chanu, Nayan M. Kakoty et al. · 2025 · Wearable Technologies

Electromyogram (EMG)-controlled prosthetic hands have advanced significantly during the past two decades. However, most of the currently available prosthetic hands fail to replicate human hand functionality and controllability. To measure the emulation of the human hand by a prosthetic hand, it is important to evaluate the functional characteristics. Moreover, incorporating feedback from end users during clinical testing is crucial for the precise assessment of a prosthetic hand. The work reported in this manuscript unfolds the functional characteristics of an EMG-CoNtrolled PRosthetIC Hand ca

A Single Dose of Baicalin Has No Clinically Significant Effect on the Pharmacokinetics of Cyclosporine A in Healthy Chinese Volunteers

Ruijuan Liu, Xia Li, Jingyao Wei et al. · 2019 · Frontiers in Pharmacology

Despite its narrow therapeutic window and large inter-individual variability, cyclosporine A (CsA) is the first-line therapy following organ transplantation. Metabolized mainly by CYP3A and being a substrate of P-glycoprotein (P-gp), CsA is susceptible to drug-drug interactions. Baicalin (BG) is a drug used for adjuvant therapy of hepatitis in traditional Chinese medicine. Since its aglycone Baicalein (B) inhibits CYP3A and P-gP, co-administration might affect CsA pharmacokinetics. This study investigated the effect of BG on CsA pharmacokinetics. In a two-period study, 16 healthy volunteers re

Augmenting Immersive Telepresence Experience with a Virtual Body

Nikunj Arora, Markku Suomalainen, Matti Pouke et al. · 2022 · IEEE Transactions on Visualization and Computer Graphics

We propose augmenting immersive telepresence by adding a virtual body, representing the user's own arm motions, as realized through a head-mounted display and a 360-degree camera. Previous research has shown the effectiveness of having a virtual body in simulated environments; however, research on whether seeing one's own virtual arms increases presence or preference for the user in an immersive telepresence setup is limited. We conducted a study where a host introduced a research lab while participants wore a head-mounted display which allowed them to be telepresent at the host's physical loc

A network analysis of female sexual function: comparing symptom networks in women with decreased, increased, and stable sexual desire

Annika Gunst, Marlene Werner, Lourens Waldorp et al. · 2018 · Scientific Reports

Problems related to low sexual desire in women are common clinical complaints, and the aetiology is poorly understood. We investigated predictors of change in levels of sexual desire using a novel network approach, which assumes that mental disorders arise from direct interactions between symptoms. Using population-based data from 1,449 Finnish women, we compared between-subject networks of women whose sexual desire decreased, increased, or remained stable over time. Networks were estimated and analyzed at T1 (2006) and replicated at T2 (2013) using R. Domains included were, among others, sexu

Recursive seed amplification detects distinct α-synuclein strains in cerebrospinal fluid of patients with Parkinson’s disease

Stefan Bräuer, Iñaki Schniewind, Elisabeth Dinter et al. · 2025 · Acta Neuropathologica Communications

Parkinson's disease (PD) is a heterogeneous neurodegenerative disorder with a wide range of clinical phenotypes. Pathologically, it is characterized by neuronal inclusions containing misfolded, fibrillar alpha-synuclein (aSyn). Prion-like properties of aSyn contribute to the spread of aSyn pathology throughout the nervous system as the disease progresses. Utilizing these properties, seed amplification assays (SAA) enable the detection of aSyn pathology in living patients. We hypothesized that structurally distinct aSyn aggregates, or strains, may underlie the clinical heterogeneity of PD. To t
