New benchmarks for direct detection of freeze-in dark matter in vector portal models

David Cerdeño · Patrick Foldenauer · Rafael López Noé · Óscar Zapata

Abstract We investigate the freeze-in of MeV-scale fermionic dark matter (DM) that couples to the Standard Model via a new vector mediator to assess the potential that future direct detection experiments have to observe new physics in either the DM or neutrino sectors. We study the minimal kinetic mixing dark photon of...

The stigma-induced diagnostic gap: a critical barrier to leprosy elimination

Phylogenomics and museomics reveal five distinct species of tiger cats in South America

Jonas Lescroart · Paola Nogales-Ascarrunz · Molly Cassatt-Johnstone · Alejandra Bonilla-Sánchez · y 9 más

Lescroart, Jonas, Nogales-Ascarrunz, Paola, Cassatt-Johnstone, Molly, Bonilla-Sánchez, Alejandra, Sartor, Caroline Charão, Angulo, Fernando, Ramirez, Jorge L., de Oliveira, Larissa Rosa, de Oliveira, Tadeu Gomes, Shapiro, Beth, Aliaga-Rossel, Enzo, Svardal, Hannes, Eizirik, Eduardo (2026): Phylogenomics and museomics r...

Comparative genomics of Candida albicans isolates from Bogotá, Colombia: Phylogenetic insights and resistance-related mutations

Luz Helena Patiño · Marina Muñoz · Angie Lorena Ramírez · Maria Jose Jimenez · y 3 más

Candida albicans is an opportunistic fungal pathogen, considered the second most frequent agent of fungal infections worldwide, responsible for high mortality in immunocompromised patients. While epidemiology and genetic diversity of this fungus have been extensively studied globally, genomic profiling in Colombia rema...

Decarbonizing Industrial Banana Drying: A Verifiable Framework for Sustainable Resource Management

Danya K. Jurado-Erazo · L. Joana Rodriguez · Carlos E. Orrego

Convective fruit drying is energy-intensive and a major greenhouse gas (GHG) source in the agri-food sector. Existing carbon footprint (CF) studies are fragmented, separating emissions accounting from economic performance and quality verification, limiting their usefulness for small and medium-sized enterprises (SMEs)...

Impacts of land-use change on bat functional diversity with implications for resilience of West African agroecosystems

Cecilia Montauban · Adam J.M. Devenish · Ivana Budinski · Nathaniel N.D. Annorbah · y 6 más

Agricultural expansion is a major driver of global biodiversity loss, reshaping species assemblages and disrupting ecological functions essential for ecosystem resilience. These effects are most pronounced in tropical forests yet remain poorly understood for many taxa, including bats that provide key ecosystem services...

Beyond traditional emission-line diagnostics: Using autoencoders to uncover active galactic nuclei in DESI spectra

J. A. Alcolea · M. Siudek · M. Eriksen · M. Mezcua · y 48 más

Context. The growing volume of spectroscopic data in modern surveys motivates the development of data-driven approaches that complement traditional emission-line diagnostics for the identification of active galactic nuclei (AGNs). Aims. We develop and validate a machine-learning (ML) framework for galaxy and AGN classi...

Contemporary automated insulin delivery systems in older adults with type 1 diabetes: A systematic review and meta-analysis

Piyush, Ratan · Marconi, Abreu · Luisa, Saldarriaga · Hilária Saugo, Faria · y 1 más

Older adults with type 1 diabetes are clinically heterogeneous, with variable cognition, dexterity, comorbidity burden, caregiver support, and prior technology experience. Evidence on automated insulin delivery systems (AIDs) in this population remains limited and largely observational. We performed a systematic review...

Multicenter evaluation of anatomical landmark versus technology-assisted techniques for chemotherapy venous access device implantation

Nicolas Felipe Camargo · Arnold Barrios · Jorge Vargas · Danilo Chaparro · y 4 más

Abstract The global incidence of cancer has significantly increased, resulting in the expanded use of innovative systemic treatments that require implantable vascular access devices, thus increasing the frequency of device implantation. These implants are associated with low complication rates, good patient tolerance,...

Artificial intelligence models for automated and semiautomated analysis and interpretation of clinical electroencephalography

Sándor Beniczky · Birgit Frauscher · Fábio A Nascimento · Shobi Sivathamboo · y 5 más

Electroencephalography is the most commonly used diagnostic tool for epilepsy. However, interpreting electroencephalograms (EEGs) requires expertise that is not widely available. Advances in digital technology and wearables have enabled large-scale EEG recording, generating vast amounts of data that cannot be managed t...
