The presence of ancient core genes reveals endogenization from diverse viral ancestors in parasitoid wasps.

Genome Biol Evol 2021 May 14. Epub 2021 May 14.

Department of Biology, University of Central Florida, Orlando, FL 32816, USA.

The Ichneumonoidea (Ichneumonidae and Braconidae) is an incredibly diverse superfamily of parasitoid wasps that includes species that produce virus-like entities in their reproductive tracts to promote successful parasitism of host insects. Research on these entities has traditionally focused upon two viral genera Bracovirus (in Braconidae) and Ichnovirus (in Ichneumonidae). These viruses are produced using genes known collectively as endogenous viral elements (EVEs) that represent historical, now heritable viral integration events in wasp genomes. Read More

From telson to attack in mantis shrimp: bridging biomechanics and behavior in crustacean contests.

Integr Comp Biol 2021 May 10. Epub 2021 May 10.

Scripps Institution of Oceanography, Marine Biology Research Division, University of California, San Diego, La Jolla, CA 92093.

In the spirit of this symposium on the physical mechanisms of behavior, we review mantis shrimp ritualized fighting, from the telson to the attack, as an inspiring example of how the integration of biomechanics and behavioral research can yield a penetrating narrative for how animals accomplish important activities, including agonistic actions. Resolving conflicts with conspecifics over valuable resources is an essential task for animals, and this takes an unusual form in mantis shrimp due to their powerful raptorial appendages. Decades of field and laboratory research have provided key insights into the natural agonistic interactions of diverse mantis shrimp species, including how they use their raptorial weapons against one another in telson sparring matches over cavities.

Multi-layer graphene pirani pressure sensors.

Nanotechnology 2021 May 10. Epub 2021 May 10.

Microelectronics, Delft University of Technology, Feldmannweg 17, Delft, 2628CT, NETHERLANDS.

The operating principle of Pirani pressure sensors is based on the pressure dependence of a suspended strip's electrical conductivity, caused by the thermal conductance of the surrounding gas which changes the Joule heating of the strip. To realize such sensors, not only materials with high temperature dependent electrical conductivity are required, but also minimization of the suspended strip dimensions is essential to maximize the responsivity and minimize the power consumption. Due to this, nanomaterials are especially attractive for this application. Read More

Conceptualizing the Role of Individual Agency in Mobility Transitions: Avenues for the Integration of Sociological and Psychological Perspectives.

Front Psychol 2021 20;12:623652. Epub 2021 Apr 20.

Department of Spatial Transformation in the Digital Age, Faculty of Spatial Planning, Dortmund Technical University, Dortmund, Germany.

With the release of the latest IPCC report, the urgency to steer the transport sector toward ecological sustainability has been recognized more and more broadly. To better understand, the prerequisites for a transition to sustainable mobility, we argue that interdisciplinary mobility research needs to revisit the interaction between social structures and individual agency by focusing on social norms. While critical sociological approaches stress the structural barriers to sustainable mobility, political discourse over sustainable mobility is still largely dominated by overly individualistic approaches, which focus on individual behavior change neglecting its social embeddedness.

Integrating behaviour change interventions and patient decision aids: How to accomplish synergistic effects?

Patient Educ Couns 2021 Apr 15. Epub 2021 Apr 15.

Leeds Unit of Complex Intervention Development (LUCID), Leeds Institute of Health Sciences, School of Medicine, University of Leeds, Leeds, UK; Research Centre for Patient Involvement (ResCenPI), Department of Public Health, Aarhus University, Denmark.

People make numerous health-related choices each day: For example, deciding to brush one's teeth or to eat well and healthy - or not to do these activities. To support complex decisions and subsequent behaviour change, both Behaviour Change Interventions (BCIs) and Patient Decision Aids (PtDAs) have been developed and evolved independently to support people in health-related decision making. In this paper, we critically review BCIs and PtDAs, examine their similarities and differences, and identify potential for integration of expertise to increase the benefits for people engaging with healthcare and health behaviours.
