Immunopotentiation by Natural Extracts: Mechanisms and Applications in Influenza Vaccine Adjuvant Development

Food Science &Nutrition, Volume 14, Issue 5, May 2026.
Natural Extracts as Candidate Influenza Vaccine Adjuvants. Seasonal influenza vaccines face limitations due to viral mutations and low efficacy in vulnerable populations. Traditional adjuvants often have safety or immune‐activation constraints, leading to increased interest in natural extracts from plants, marine organisms, and fungi.

Surface slicks structure microbial and viral neuston in relation to biogeochemical conditions

Limnology and Oceanography, Volume 71, Issue 5, May 2026.
Abstract The sea‐surface microlayer (hereafter microlayer), which forms the interface between the ocean and atmosphere, plays a key role in nutrient cycling and microbial dynamics. Coastal slicks, which are viscous and biogenic surface films, often serve as hotspots for microbial activity, yet their structure and interactions remain incompletely ...

CONCERT: A Modular Reconfigurable Robot for Construction

Journal of Field Robotics, Volume 43, Issue 3, Page 1332-1362, May 2026.
ABSTRACT This paper presents CONCERT, a fully reconfigurable modular collaborative robot (cobot) for multiple on‐site operations in a construction site. CONCERT has been designed to support human activities in construction sites by leveraging two main characteristics: high‐power density motors and modularity. In this way, the robot is able to perform a
