Human organoids: a new dimension in cell biology.

Organoids derived from stem cells or tissues in culture can develop into structures that resemble the in vivo anatomy and physiology of intact organs. Human organoid cultures provide the potential to study human development and model disease processes with the same scrutiny and depth of analysis customary for research with nonhuman model organisms. Resembling the complexity of the actual tissue or organ, patient-derived human organoid studies may accelerate medical research, creating new opportunities for tissue engineering and regenerative medicine, generating knowledge and tools for preclinical studies, including drug development and testing.

Disgusting microbes: The effect of disgust on perceptions of risks related to modifying microbiomes.

Research on perceived risks of scientific issues has largely overlooked the influence of disgust as a predictor. Here, we examine the impact of disgust on perceived risks of modifying microbiomes using a 2 (emotion) × 2 (focus) experiment embedded in an online survey. We find evidence of moderated mediation where individuals exposed to an article about microbiome research and therapies with explicit references to disgusting stimuli perceived greater risk through a mediating variable, elicited disgust.

Scientists: Engage the Public!

Scientists must communicate about science with public audiences to promote an understanding of complex issues that we face in our technologically advanced society. Some scientists may be concerned about a social stigma or "Sagan effect" associated with participating in public communication. Recent research in the social sciences indicates that public communication by scientists is not a niche activity but is widely done and can be beneficial to a scientist's career.
