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.

Abstract. Observed correlations between short-term decreases in cosmic ray ionisation and cloud and aerosol properties have been attributed to short-term decreases in the ion-induced nucleation rate. We use a global aerosol microphysics model to determine whether a 10 day reduction of 15% in the nucleation rate could generate a statistically significant response in aerosol concentrations and optical properties. As an upper limit to the possible effect of changes in ion-induced nucleation rate, we perturb the total nucleation rate, which has been shown to generate particle concentrations and nu

Abstract The purpose of this study was to analyze quantitative diffusion tensor imaging measures across the spectrum of traumatic brain injury severity and evaluate their trajectories in military service members. Participants were 96 U.S. military service members and veterans who had sustained a mild traumatic brain injury [including complicated mild traumatic brain injury (n = 16) and uncomplicated mild traumatic brain injury (n = 68)], moderate-severe traumatic brain injury (n = 12), and controls (with or without orthopaedic injury, n = 39). All participants had been scanned at least twice,

INTRODUCTION: Scuba diving represents a combination of exercise and changes in environmental conditions. This study aimed to evaluate changes in haematological parameters after recreational scuba diving in order to identify clinically significant changes. MATERIALS AND METHODS: The study included males, 17 recreational divers, median age (range) 41 (30-52) years. Blood samples were taken before diving, immediately after diving to 30 meters for 30 minutes, 3 hours and 6 hours after diving. Complete blood counts were analyzed on the Cell Dyn Ruby haematology analyzer. Statistical significance be

BACKGROUND: Myelodysplastic syndrome (MDS) may be induced by certain mutagenic environmental or chemotherapeutic toxins; however, the role of susceptibility genes remains unclear. The G/G genotype of the single-nucleotide polymorphism (SNP) rs1617640 in the erythropoietin (EPO) promoter has been shown to be associated with decreased EPO expression. We examined the association of rs1617640 genotype with MDS. METHODS: We genotyped the EPO rS1617640 SNP in 189 patients with MDS, 257 with acute myeloid leukemia (AML), 106 with acute lymphoblastic leukemia, 97 with chronic lymphocytic leukemia, 353

Chronic hyperglycemia is the defining feature of type 2 diabetes mellitus (T2DM) and a central driver of its long-term complications, including microvascular and macrovascular diseases. Among these, cardiovascular disease (CVD) remains the leading cause of morbidity and mortality in individuals with T2DM. Persistent glucose elevation activates multiple interrelated biochemical pathways, including the polyol pathway, formation of advanced glycation end-products, protein kinase C activation, oxidative stress via several cellular mechanisms, as well as the hexosamine biosynthetic pathway. These p

PURPOSE OF REVIEW: We synthesize the latest evidence (published 2020 to 2025) on the role of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in cardiovascular health, emphasizing biological mechanisms and key findings from observational studies and clinical trials related to cardiovascular disease (CVD) risk and outcomes. RECENT FINDINGS: EPA and DHA modulate lipid metabolism, inflammation, platelet and endothelial function, the gut-heart axis, ion channels and autonomic function via vagal tone, supporting cardiovascular health. While individual RCTs have produced variable results,

Polyphenols, plant-derived bioactive compounds, are known for their antioxidant, anti-inflammatory, and antimicrobial properties, benefiting plant-based foods. Fermentation, driven by microbial enzymes like glycosidases, esterases, and decarboxylases, alters the chemical structure of polyphenols, enhancing their bioavailability and bioactivity. This review explores the transformation of polyphenols, particularly flavonoids and phenolic acids, during fermentation, resulting in bioactive metabolites with increased solubility, stability, and antioxidant activity, improving gastrointestinal absorp

Advances in this century regarding allogeneic hematopoietic stem cell transplantation (allo-HSCT) have led to an expanding population of long-term survivors, many of whom suffer severe side effects, particularly those related to graft-versushost disease (GVHD), a potentially multi-systemic disorder caused by immunoeffector donor lymphocytes that destroy host tissues. The GVHD, especially in its chronic form (cGVHD), generates considerable morbidity and compromises the physical capacity of patients. We have reviewed the main pathophysiological aspects of the disease as well as the data availabl

BACKGROUND: Artificial intelligence (AI) chatbots are increasingly used for medical inquiries, including sensitive topics like sexually transmitted diseases (STDs). However, concerns remain regarding the reliability and readability of the information they provide. This study aimed to assess the reliability and readability of AI chatbots in providing information on STDs. The key objectives were to determine (1) the reliability of STD-related information provided by AI chatbots, and (2) whether the readability of this information meets the recommended standarts for patient education materials.
