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.

Genomics of Neotropical biodiversity indicators: Two butterfly radiations with rampant chromosomal rearrangements and hybridization

Eva S. M. van der Heijden, Karin Näsvall, Fernando Seixas et al. · 2025 · Proceedings of the National Academy of Sciences

A central question in evolutionary biology is what drives the diversification of lineages. Rapid, recent radiations are ideal systems for this question because they still show key morphological and ecological adaptations associated with speciation. While most research on recent radiations focuses on those occurring in insular environments, less attention has been given to continental radiations with complex species interactions. Here, we study the drivers of continental radiations of Melinaea and Mechanitis butterflies (Nymphalidae: Ithomiini), which have rapidly radiated in the continental Ne

Rethinking the ‘wellness influencer’: Medical doctors, lifestyle expertise and the question of credentials

Rachel O’Neill · 2025 · International Journal of Cultural Studies

Medical doctors are central to existing networks for wellness content on Instagram in and beyond the UK, yet remain overlooked within scholarship concerned with this terrain. Taking a case study approach, this article examines three such figures prominent in the UK context. In doing so, it challenges existing conceptualisations of the 'wellness influencer' and argues for an expanded understanding of the category, one that does not assume its representatives are 'lay' persons without recognised expertise in health and well-being. The analysis developed demonstrates that credentials cannot resol

Bridging the missing middle in osseointegration: meso-scale topography between macro design and microroughness

Takahiro Ogawa, Rune Shibata, Keiji Komatsu et al. · 2025 · International Journal of Implant Dentistry

PURPOSE: Despite decades of clinical success with microrough implant surfaces, persistent challenges-particularly the biological trade-off between osteoblast proliferation and differentiation-highlight the need for novel surface design strategies. This review investigates the potential of meso-scale topography (10-500 μm) as a promising and underexplored dimension in implant surface engineering, situated between macro-level implant geometry and conventional microroughness. METHODS: A systematic review, supplemented by a targeted literature search, was conducted to evaluate the biological and m

Pulsatile sequential drug release system for cascade tumor deep penetration and differentiation therapy to enhance chemoimmunotherapy

Fengxiang Liu, Shipeng Ning, Xia Wang et al. · 2025 · Science Advances

Cancer stem cells (CSCs) and myeloid-derived suppressor cells (MDSCs) contribute to chemoresistance and immunosuppression, constraining chemoimmunotherapy outcomes. Differentiation therapy, aiming to mature CSCs and MDSCs, shows great promise. However, its efficacy is hindered by limited accessibility in hypoxic deep tumor regions. Inspired by the apoptotic body (ApoBD)-mediated deep tumor penetration, we design a pulsatile sequential drug release system with a core-shell structure. The reversible acid-responsive shell protonates and swells in lysosomes to release doxorubicin, inducing lysosom

NANO-LM: An updated scorecard for the clinical assessment of patients with leptomeningeal metastases

Émilie Le Rhun, Lakshmi Nayak, Mary Jane Lim-Fat et al. · 2024 · Neuro-Oncology

BACKGROUND: There are no validated tools for the clinical neurological assessment of patients with leptomeningeal metastases (LM). However, clinical examination during the course of the disease guides medical management and is part of response assessment in clinical trials. Because neuroimaging may not always be obtained owing to rapid clinical deterioration, clinical neurological assessment of LM is essential, and standardization is important to minimize rater disagreement. METHODS: The Response Assessment in Neuro-oncology-LM group launched a 2-step process, aiming at improving and standardi

The Functional Role of Polyphenols Across the Human Lifespan

Bekir Enes Koca, Sümeyye Sarıtaş, Mikhaël Bechelany et al. · 2025 · International Journal of Molecular Sciences

Polyphenols are bioactive molecules that occur naturally in plants and exhibit a diverse array of properties, including antioxidant, anti-inflammatory, and anti-obesity effects, all of which have been supported by numerous studies. They are categorized into four main groups: flavonoids, phenolic acids, stilbenes, and lignans. Polyphenols demonstrate a wide range of health-promoting effects throughout human life, from the womb to old age. They can exert these effects by modulating signaling pathways, regulating gut microbiota, influencing gene expression, and regulating epigenetic pathways. Thi

Oxygen level alters energy metabolism in bovine preimplantation embryos

Nina Boskovic, Marilin Ivask, Gamze Yazgeldi Gunaydin et al. · 2025 · Scientific Reports

Abstract Mammalian preimplantation embryo development is a complex sequence of events. This period of development is sensitive to oxygen (O 2 ) levels that can affect various cellular processes. We compared the influence of O 2 tension by culturing embryos either in normoxic (20% O 2 ) or physiological hypoxic (6% O 2 ) conditions, or sequential low O 2 concentration starting with 6% O 2 until 16-cell stage and then switching to ultrahypoxic conditions (2% O 2 ). Due to ethical concerns, we used bovine as an animal model with a good similarity of embryogenesis to human. We found that the cleav
