Stakeholder relations in Australian science journalism.

This study explores the relationships between scientists, science communicators and science journalists in Australia. Building upon a smaller previous study, this article provides an overview of the science media landscape across a nation through the use of semi-structured interviews with members of stakeholder groups. Although relationships between each of the groups are generally positive, a lack of clear understanding of the professional practice and cultures of the different groups sometimes appear to hinder positive interactions.

Tropomyosin Tpm 2.1 loss induces glioblastoma spreading in soft brain-like environments.

Introduction: The brain is a very soft tissue. Glioblastoma (GBM) brain tumours are highly infiltrative into the surrounding healthy brain tissue and invasion mechanisms that have been defined using rigid substrates therefore may not apply to GBM dissemination. GBMs characteristically lose expression of the high molecular weight tropomyosins, a class of actin-associating proteins and essential regulators of the actin stress fibres and focal adhesions that underpin cell migration on rigid substrates.
