Mothbox and Mothbot: Automated light trap and data processing system for scalable insect monitoring

Methods in Ecology and Evolution, Volume 17, Issue 7, Page 2082-2091, July 2026.
Abstract Insects represent the most diverse group of organisms on Earth and comprise the majority of known species; yet they are seldom accounted for in large‐scale biodiversity monitoring systems and conservation planning. We have developed the Mothbox—an open source automated light trap that makes insect monitoring accessible to non‐specialists and ...

Survival and Behavior of Amphibians in a Seasonally Flooded Tropical Forest

Biotropica, Volume 58, Issue 4, July 2026.
How do tropical amphibians survive seasonal flooding? A three‐year capture–mark–recapture study in Costa Rica revealed species‐specific responses to flood events, with flooding reducing apparent survival in some species while others persisted through behavioral adaptations and use of arboreal refugia.

Hemagglutination Inhibition and Alternate Serologic Responses Following Influenza A(H3N2) Virus Infection

Influenza and Other Respiratory Viruses, Volume 20, Issue 7, July 2026.
ABSTRACT Background Although the hemagglutination inhibition (HAI) titer remains the gold standard correlate of protection against influenza, it does not fully capture the broader antibody responses that contribute to immunity. Methods We analyzed immune responses in paired pre‐infection and convalescent sera from 306 RT‐PCR–confirmed A(H3N2 ...

A Three‐Step Diagnostic Strategy for Malignant Pleural Effusions

Cancer Medicine, Volume 15, Issue 6, June 2026.
ABSTRACT New diagnostic tools, such as high fluorescence cells (HFc) and tumor markers (TMs), have emerged in the quest to accurately diagnose malignant pleural effusion (MPE). This study evaluated the diagnostic performance of the HFc and TMs combination.

Pancreatic Adenocarcinoma: Diagnosis by Ultrasound‐Guided Fine‐Needle Aspiration—Cyto‐Histological Correlation and Experience at a Multidisciplinary Tertiary Reference Center

Diagnostic Cytopathology, Volume 54, Issue 6, Page 403-416, June 2026.
ABSTRACT Background Pancreatic adenocarcinoma (PDAC) is characterized by its poor prognosis. Cytology is essential for diagnostic confirmation and ancillary studies. The endoscopic ultrasound (EUS) set a precedent, facilitating cytological sampling through fine‐needle aspiration (FNA), with a sensitivity of 93% and a specificity of 95%.

The Prohibition of Approach in Child‐To‐Parent Violence: Between the Protection of the Victim and the Preservation of the Family Bond

Journal of Investigative Psychology and Offender Profiling, Volume 23, Issue 2, June 2026.
