Derived faunivores are the forerunners of major synapsid radiations.

Evolutionary radiations generate most of Earth's biodiversity, but are there common ecomorphological traits among the progenitors of radiations? In Synapsida (the mammalian total group), 'small-bodied faunivore' has been hypothesized as the ancestral state of most major radiating clades, but this has not been quantitatively assessed across multiple radiations. To examine macroevolutionary patterns in a phylogenetic context, we generated a time-calibrated metaphylogeny ('metatree') comprising 1,888 synapsid species from the Carboniferous through the Eocene (305-34 Ma) based on 269 published character matrices. We used comparative methods to investigate body size and dietary evolution during successive synapsid radiations.

Imagination: A New Foundation for the Science of Mind.

After a long hiatus, psychology and philosophy are returning to formal study of imagination. While excellent work is being done in the current environment, this article argues for a stronger thesis than usually adopted. Imagination is not just a peripheral feature of cognition or a domain for aesthetic research.

Affect, Belief, and the Arts.

The cultural project is a therapeutic melding of emotion, symbols, and knowledge. In this paper, I describe how spiritual emotions engendered through encounters in imaginative culture enable fixation of metaphysical beliefs. Evolved affective systems are domesticated through the social practices of imaginative culture so as to adapt people to live in culturally defined cooperative groups.

Music in Quarantine: Connections Between Changes in Lifestyle, Psychological States, and Musical Behaviors During COVID-19 Pandemic.

Music is not only the art of organized sound but also a compound of social interaction among people, built upon social and environmental foundations. Since the beginning of the COVID-19 outbreak, containment measures such as shelter-in-place, lockdown, social distancing, and self-quarantine have severely impacted the foundation of human society, resulting in a drastic change in our everyday experience. In this paper, the relationships between musical behavior, lifestyle, and psychological states during the shelter-in-place period of the COVID-19 pandemic are investigated.

Collaborating in Isolation: Assessing the Effects of the Covid-19 Pandemic on Patterns of Collaborative Behavior Among Working Musicians.

The Covid-19 pandemic severely limited collaboration among musicians in rehearsal and ensemble performance, and demanded radical shifts in collaborative practices. Understanding the nature of these changes in music creators' patterns of collaboration, as well as how musicians shifted prioritizations and adapted their use of the available technologies, can offer invaluable insights into the resilience and importance of different aspects of musical collaboration. In addition, assessing changes in the collaboration networks among music creators can improve the current understanding of genre and style formation and evolution.

Incorporating Research into an Undergraduate Animal Behavior Course using Zoos and Webcams.

In our nonmajors animal behavior class, we developed a semester-long research project assignment that incorporates project-based learning (PBL) and the opportunity for Course-Based Undergraduate Research Experiences (CUREs) that introduces, assesses, and applies the course concepts. This project can easily be adapted for nonmajors biology, majors biology, or other more general survey classes, including remote courses. This student-led project involves a field trip for data collection at our local zoo, additional data collection using webcams, and writing and presenting a scientific report.

Improvised Caregiving or How a Famous Comedy Theatre Found Itself in Health Care.

For more than 60 years, The Second City has used the techniques of improvisation to train some of the world's funniest and most famous people-among them Bill Murray, Tina Fey, Amy Poehler, Jordan Peele, John Belushi, and Joan Rivers. The same skills that generate laughter are just as powerful and potent in any situation that requires human beings to navigate complexity, solve problems in group settings, and listen with the intent to hear. Collaborating with Caring Across Generations, Cleveland Clinic, and other organizations, The Second City has developed training modules that give individuals and groups more agency in the health care space.

The Science of Comedy (Sort of).

From an academic point of view, humor studies have traditionally lived in the rather unfunny world of philosophy departments. More recently, psychologists and neuroscientists have begun to study mechanisms of humor and laughter. An argument can be made that approaching humor studies from the perspective of comedy creation offers practical tools for using comedy and humor in everyday communication and connection.

Training in improvisation techniques helps reduce caregiver burden and depression: Innovative Practice.

This study measured outcomes of a novel pilot program designed to teach improvisation skills to caregivers of family members with dementia. Fifteen caregivers completed questionnaires measuring changes in their perception of burden (Zarit Burden Interview), depression (Beck Depression Inventory), their cared-for person's neuropsychiatric symptoms (Neuropsychiatric Inventory Questionnaire), and experiences related to caregiving. Caregivers' depressive symptoms and sense of burden significantly decreased after completing the six-week program.

Transaural experiments and a revised duplex theory for the localization of low-frequency tones.

The roles of interaural time difference (ITD) and interaural level difference (ILD) were studied in free-field source localization experiments for sine tones of low frequency (250-750 Hz). Experiments combined real-source trials with virtual trials created through transaural synthesis based on real-time ear canal measurements. Experiments showed the following: (1) The naturally occurring ILD is physically large enough to exert an influence on sound localization well below 1000 Hz.

Kinematics of unconstrained tactile texture exploration.

A hallmark of tactile texture exploration is that it involves movement between skin and surface. When we scan a surface, small texture-specific vibrations are produced in the skin, and specialized cutaneous mechanoreceptors convert these vibrations into highly repeatable, precise, and informative temporal spiking patterns in tactile afferents. Both texture-elicited vibrations and afferent responses are highly dependent on exploratory kinematics, however; indeed, these dilate or contract systematically with decreases or increases in scanning speed, respectively.

Migration of immature and mature B cells in the aged microenvironment.

Studies in aged mice show that the architecture of B-cell areas appears disrupted and that newly made B cells fail to incorporate into the spleen. These observations may reflect altered migration of immature and mature B cells. Using adoptive transfer, we tested the effect of the aged microenvironment and the intrinsic ability of donor B cells from aged mice to migrate to spleens of intact hosts.

Plasma cell purification from murine bone marrow using a two-step isolation approach.

Interest in plasma cells has increased greatly in the past decade. While several studies have examined the longevity and transcriptional control of antibody secreting cells in vivo, few studies have examined freshly isolated plasma cells ex vivo. Studies of primary plasma cells have been limited primarily due to the difficulty of isolating the large numbers of plasma cells necessary for experiments.

The effects of microenvironment and internal programming on plasma cell survival.

Two populations of plasma cells (PCs) are formed after immunization. A short-lived population in the spleen and lymph nodes provides rapid protection. A long-lived population, mainly in the bone marrow, provides lasting immunity.
