Alfven waves in the solar corona.

Alfvén waves, transverse incompressible magnetic oscillations, have been proposed as a possible mechanism to heat the Sun's corona to millions of degrees by transporting convective energy from the photosphere into the diffuse corona. We report the detection of Alfvén waves in intensity, line-of-sight velocity, and linear polarization images of the solar corona taken using the FeXIII 1074.7-nanometer coronal emission line with the Coronal Multi-Channel Polarimeter (CoMP) instrument at the National Solar Observatory, New Mexico.

Ectopic expression of a cecropin transgene in the human malaria vector mosquito Anopheles gambiae (Diptera: Culicidae): effects on susceptibility to Plasmodium.

Genetically altering the disease vector status of insects using recombinant DNA technologies is being considered as an alternative to eradication efforts. Manipulating the endogenous immune response of mosquitoes such as the temporal and special expression of antimicrobial peptides like cecropin may result in a refractory phenotype. Using transgenic technology a unique pattern of expression of cecropin A (cecA) in Anopheles gambiae was created such that cecA was expressed beginning 24 h after a blood meal in the posterior midgut.

Experiencing chronic illness: cocreating new understandings.

This study was conducted as part of a research course in which new partnerships with area citizens and community-driven programs of research were developed. Working together, the teachers, students, and citizens were able to document their practical knowledge through conducting a study of the lived experiences of chronic illness using Heideggerian hermeneutical phenomenology. The pattern, Experiencing Chronic Illness: Cocreating New Understanding, and three themes emerged during the analysis of the data (a) focusing on functional status doesn't adequately account for the experience of chronic illness, (b) decentering the focus on the treatment of symptoms makes way for equally important discussions of meaning making in the context of chronic illness, and (c) the objectified language of healthcare covers over how chronic illness is experienced.

Modifiable risk factors predict functional decline among older women: a prospectively validated clinical prediction tool. The Study of Osteoporotic Fractures Research Group.

Objective: To identify modifiable predictors of functional decline among community-residing older women and to derive and validate a clinical prediction tool for functional decline based only on modifiable predictors.

Design: A prospective cohort study.

Setting: Four geographic areas of the United States.
