GPCRs in CAR‐T Cell Immunotherapy: Expanding the Target Landscape and Enhancing Therapeutic Efficacy

Advanced Science, Volume 13, Issue 35, 24 June 2026.
Chimeric antigen receptor T cell therapy faces dual challenges of target scarcity and an immunosuppressive microenvironment in solid tumors. This review highlights how G protein‐coupled receptors can serve as both novel targets to expand the therapeutic scope and functional modules to enhance CAR‐T cell efficacy.

A model to quantify the probability of collision between birds and aircraft: Applications for onboard lighting

Ecological Applications, Volume 36, Issue 3, April 2026.
Abstract Globally, bird and aircraft collisions are a major safety hazard and monetary expense for the aviation industry. Empirical evidence suggests that the behavioral response of an animal within close proximity of an approaching vehicle is a critical factor in determining whether a collision occurs.
