Practical considerations for pathologists when selecting digital pathology systems: an ESDIP guide

The Journal of Pathology, Volume 270, Issue 3, Page 328-341, November 2026.
Abstract The implementation of digital pathology (DP) has been reported across academic, public, and private laboratory settings, providing valuable insights into workflow transformation. However, comparatively little guidance exists on how DP systems should be evaluated prior to acquisition and deployment.

Porting Deep‐Learning Phase Pickers From TensorFlow to PyTorch for SeisBench Without Retraining

Earth and Space Science, Volume 13, Issue 11, November 2026.
Abstract SeisBench has become the premier open‐source library for accessing pretrained deep‐learning seismic phase pickers through a unified Python interface. Because SeisBench distributes models exclusively in PyTorch, phase pickers originally developed in TensorFlow must be converted to PyTorch before integration into the library. Although retraining

Microbiome‐Based Assessment of Topical Scalp Product‐Associated Microbiome Modulation

Journal of Cosmetic Dermatology, Volume 25, Issue 11, November 2026.
ABSTRACT Background The scalp microbiome plays a crucial role in maintaining scalp health, yet few studies have examined how topical scalp cosmeceuticals affect bacterial and fungal communities. In this study we aim to investigate the impact of a scalp serum on the scalp microbiome and physiology.
