Rationalizing the Influence of Small-Molecule Dopants on Guanine Crystal Morphology.

Many spectacular optical phenomena in animals are produced by reflective assemblies of guanine crystals. The crystals comprise planar H-bonded layers of π-stacked molecules with a high in-plane refractive index. By preferentially expressing the highly reflective π-stacked (100) crystal face and controlling its cross-sectional shape, organisms generate a diverse array of photonic superstructures.

Curricular Reform in Serious Illness Communication and Palliative Care: Using Medical Students' Voices to Guide Change.

Purpose: To gather and leverage the voices of students to drive creation of required, integrated palliative care curricula within undergraduate medical education in Massachusetts, which is lacking in a majority of U.S. medical schools.

A Call to Action: Using Curriculum Mapping at Four Medical Schools in Massachusetts to Advance Serious Illness Communication Training in Undergraduate Medical Education.

Practicing physicians require serious illness communication (SIC) skills to ensure high-quality, humanistic care for patients and families as they face life-changing medical decisions. However, a majority of U.S.

Sniffing the human body volatile hexadecanal blocks aggression in men but triggers aggression in women.

In terrestrial mammals, body volatiles can effectively trigger or block conspecific aggression. Here, we tested whether hexadecanal (HEX), a human body volatile implicated as a mammalian-wide social chemosignal, affects human aggression. Using validated behavioral paradigms, we observed a marked dissociation: Sniffing HEX blocked aggression in men but triggered aggression in women.

Hodgkin lymphoma survivor perspectives on their engagement in treatment decision-making and discussion of late effects.

Background: Hodgkin lymphoma has a bimodal age distribution with the first peak occurring within young adulthood and the second, among older adults. Although current therapy provides excellent disease control, survivors are at risk of developing treatment-related late effects (LEs). We sought to understand how survivors in active survivorship care perceived their role in treatment decision-making and when they acquired an understanding of LEs.
