DNA Origami Colloidal Crystals: Opportunities and Challenges.

Over the last three decades, colloidal crystallization has provided an easy-to-craft platform for mesoscale engineering of photonic and phononic crystals. Nevertheless, the crystal lattices achieved thus far with commodity colloids are largely limited to symmetric and densely packed structures, restricting their functionalities. To obtain non-close-packed crystals and the resulting complexity of the available structures, directional binding between "patchy" colloids has been pursued.

Utility of ocean wave parameters in ambient noise predictiona).

This study is concerned with prediction of the "wind noise" component of ambient noise (AN) in the ocean. It builds on the seminal paper by Felizardo and Melville [(1995). J.

Loneliness Among Older Caregivers: An Analysis of the 2020 California Health Interview Survey.

Aging and caregiving are each risk factors for loneliness, but little is known about loneliness among older caregivers. Using the 2020 California Health Interview Survey ( = 7638), this study examined the relationship between (1) caregiving status and loneliness among older adults; (2) sociodemographic, technology, health, and caregiving characteristics and loneliness among older caregivers; and (3) compared how these variables relate to loneliness among older caregivers of persons with dementia versus non-dementia conditions. Findings revealed that 15% of older caregivers experienced loneliness, with dementia caregiving significantly increasing this likelihood.

The microbiome and metatranscriptome of a panel from the mapping population reveal complex assembly and function involving host influence.

provide an optimal system for deciphering the host-microbiome interactions at various levels. We analyzed the pitcher microbiomes and metatranscriptomes of the parental species, and F1 and F2 generations from the mapping population ( X ) utilizing high-throughput sequencing methods. This study aimed to examine the host influences on the microbiome structure and function and to identify the key microbiome traits.

Using space lidar to infer bubble cloud depth on a global scale.

Visible and microwave satellite measurements can provide the global whitecap fraction. The bubble clouds are three-dimensional structures, and a space-based lidar can provide complementary observations of the bubble depth. Here, we use lidar measurements of the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) satellite to quantify global bubble depth from the depolarization.
