Social dominance influences individual susceptibility to an evolutionary trap in mosquitofish.

Plastic pollution threatens almost every ecosystem in the world. Critically, many animals consume plastic, in part because plastic particles often look or smell like food. Plastic ingestion is thus an evolutionary trap, a phenomenon that occurs when cues are decoupled from their previously associated high fitness outcomes.

"Telephone Angels" Against Loneliness: Experimental Evaluation of the Effectiveness of Telephone Partnerships with Older Adults.

Loneliness affects many older adults. As part of the "Telephone Angel" project, telephone partnerships between volunteers and older adults affected by loneliness were designed to counteract experiencing loneliness. Volunteers (100 ≤  ≤ 114) and older adults who are (22 ≤  ≤ 45) and who are not (25 ≤  ≤ 71) part of the project were surveyed twice.

Implementation of simultaneous ultraviolet/visible and x-ray absorption spectroscopy with microfluidics.

X-ray spectroscopies are uniquely poised to describe the geometric and electronic structure of metalloenzyme active sites under a wide variety of sample conditions. UV/Vis (ultraviolet/visible) spectroscopy is a similarly well-established technique that can identify and quantify catalytic intermediates. The work described here reports the first simultaneous collection of full in situ UV/Vis and high-energy resolution fluorescence detected x-ray absorption spectra.

Sequence-dependent conformational preferences of disordered single-stranded RNA.

Disordered single-stranded RNA (ssRNA) molecules, like their well-folded counterparts, have crucial functions that depend on their structures. However, since native ssRNAs constitute a highly heterogeneous conformer population, their structural characterization poses challenges. One important question regards the role of sequence in influencing ssRNA structure.

Hospital-level variation in cardiac rehabilitation metrics.

Background: To inform the delivery of cardiac rehabilitation (CR) care nationwide at the hospital level, we described hospital-level variation in CR metrics, overall and stratified by the hospital's tier of cardiac care provided.

Methods: This retrospective cohort analysis used Medicare fee-for-service (FFS) data (2018-2020), Parts A and B, and American Hospital Association (AHA) data (2018). We included beneficiaries with an acute myocardial infarction (AMI), percutaneous coronary intervention (PCI), or coronary artery bypass graft (CABG) in 2018, aged ≥65 years, and continuously enrolled in a FFS plan.
