The freshwater cnidarian Hydra has been a model system for regeneration and developmental biology for over 250 years, but much remains unknown about their biodiversity and global distribution. As a citizen scientist, you can contribute to our understanding of Hydra in the wild by becoming a "Hydra Hunter". All it takes is a few simple materials and a little patience. Collecting Hydra in the wild can be challenging. You will certainly not find them everywhere you look. Keep in mind that NOT finding Hydra is still useful information because this will help us understand the environmental factors that effect their distribution.

Hydra collecting kits were purchased with a grant to Kimberly Sladek from the University of San Diego Associated Students Government. Thank you to Rob Steele for helpful feedback on this protocol.

Abstract Family caregivers (FCs) of institutionalized noncommunicative older persons reported multiple unmet communication needs focusing on the need to receive reliable and regular updates on the patient’s condition. We have developed a mobile app for improving communication between FCs and healthcare professionals (HPs), based on 152 interviews with FCs and 13 discussion groups with HPs from four Israeli geriatric facilities. Both parties participated in app planning, tailoring it to their needs and abilities. App use implementation encountered major obstacles including the bureaucratic process concerning signing contracts between the university and software development firms, which hindered the process for a full year; data security department required disproportionate security levels that interfered with user experience and delayed the development process; the study’s definition varied across different ethics/Helsinki committees (Institutional Review Boards; IRBs), which led to different demands, e.g., insurance for medical clinical trials although no drugs or medical device were involved; lack of cooperation by mid-level staff members despite the institutional adoption of the app project; low utilization by HPs resulted in FCs not receiving timely responses. Despite these and other obstacles, we tested app use for 15 months in one facility in a pre-post-design with intervention and control groups, and we have since begun testing it in another facility. FCs who had used the app had positive feedback and wished to continue using it. App use optimization requires implementation planning, assimilating changes in each facility’s work procedures and HP’s engagement and motivation and thus depends on institutional procedures and politics.

In 1990 (Fluegeman and Orr) the writers published a short study on known North American cyclocystoids. This enigmatic group is best represented in the United States Devonian by only two specimens, both illustrated in the 1990 report. Previously, the Cortland, New York, specimen initially described by Heaslip (1969) was housed at State University College at Cortland, New York, and the Logansport, Indiana, specimen was housed at Ball State University, Muncie, Indiana. Both institutions recognize the importance of permanently placing these rare specimens in a proper paleontologic repository with other cyclocystoids. Therefore, these two specimens have been transferred to the curated paleontologic collection at the University of Cincinnati Geological Museum where they can be readily studied by future workers in association with a good assemblage of Ordovician specimens of the Cyclocystoidea.
