The Vaccine Innovation Center at Korea University's College of Medicine successfully held the 2025 Vaccine Expert Training Program, attended by over 380 experts and researchers from various fields. The program aims to foster domestic vaccine R&D experts and promote the development of commercially available vaccines.

How a small number of mutations can fuel outbreaks of western equine encephalitis virus

A single mutation in the spike protein of western equine encephalitis virus is enough to prevent it from attaching to human and horse cells. However, a change in the viral spike protein enables WEEV strains to attach to a different receptor, found on mammalian brain cells, which is shared by its cousin eastern equine encephalitis virus.

Fear of rejection influences how children conform to peers

Children who fear rejection are more likely to conform to academic expectations, while those expecting rejection resist conforming to both academic and popular behaviors. Rejection sensitivity is a key predictor of depression in children, influencing their emotional and cognitive reactions to potential rejection.

NK cells complexed with bispecific antibody yield high response rates in patients with lymphoma

A Phase I trial demonstrates AFM13-NK cells are safe and highly effective in heavily pretreated patients with refractory CD30-positive lymphomas, achieving an overall response rate of 92.9% and complete response of 66.7%. The treatment was well-tolerated, with no cases of cytokine release syndrome or graft-versus-host disease.

Enhancing heat transfer using the turbulent flow of viscoelastic fluids

Viscoelastic fluids exhibit a unique relaxation time that interacts with turbulence, resulting in an unexpected meandering motion. This interaction leads to three distinct flow states: low, middle, and high diffusivity states, with the high-diffusivity state significantly enhancing heat transfer efficiency.
