ABSTRACT
We present a summary of the campaign of remote observations that supported the European Space Agency's Rosetta mission. Telescopes across the globe (and in space) followed comet 67P/Churyumov-Gerasimenko from before Rosetta's arrival until nearly the end of the mission in September 2016. These provided essential data for mission planning, large-scale context information for the coma and tails beyond the spacecraft and a way to directly compare 67P with other comets. The observations revealed 67P to be a relatively 'well-behaved' comet, typical of Jupiter family comets and with activity patterns that repeat from orbit to orbit. Comparison between this large collection of telescopic observations and the in situ results from Rosetta will allow us to better understand comet coma chemistry and structure. This work is just beginning as the mission ends-in this paper, we present a summary of the ground-based observations and early results, and point to many questions that will be addressed in future studies.This article is part of the themed issue 'Cometary science after Rosetta'.
ABSTRACT
Two versions of a multicomponent mind-body wellness intervention were tested. One hundred seventy-eight physician-referred HMO patients (mean age = 64.5) were randomly assigned to a classroom intervention, a home study intervention, or a wait-list control group. Both interventions provided instruction on mind-body relationships, relaxation training, cognitive restructuring, problem solving, communication, behavioral treatment for insomnia, nutrition, and exercise. The home version was delivered by class videotapes and readings. Compared with the control condition, both interventions led to significant decreases in self-reports of pain, sleep difficulties, and symptoms of depression and anxiety. The home course also led to a significant decrease in self-reported frequency of medical symptoms, and the classroom program resulted in a significant decrease in "chance" health locus of control beliefs. No effects were obtained for health behaviors, life satisfaction, HMO satisfaction, and other health locus of control beliefs. A lower cost, more accessible home study version of a mind-body wellness program can be an effective alternative to classroom instruction.

The authors tested the efficacy of a mind/body wellness intervention for older adults with chronic illness. They randomly assigned 243 physician-referred patients from an urban HMO to a classroom intervention or a wait-list control group. The intervention provided instruction on mind/body relationships; relaxation training; cognitive restructuring; problem-solving; communication; and behavioral treatment for insomnia, nutrition, and exercise. At posttreatment, the intervention group had significant decreases in self-reported sleep difficulties, pain, anxiety, and depression symptoms compared with controls. The intervention also led to a significant decrease in "chance" and "powerful others" health locus of control beliefs. At 1-year follow-up, the intervention group maintained benefits in sleep and health locus of control and also reported a significant increase in health behaviors compared with controls. Pain, anxiety, and depression benefits were not maintained. This type of classroom intervention appears to have some lasting effects on health behaviors and beliefs.
