Exposure to climate change information predicts public support for solar geoengineering in Singapore and the United States.

Solar geoengineering is a controversial climate policy measure that could lower global temperature by increasing the amount of light reflected by the Earth. As scientists and policymakers increasingly consider this idea, an understanding of the level and drivers of public support for its research and potential deployment will be key. This study focuses on the role of climate change information in public support for research and deployment of stratospheric aerosol injection (SAI) in Singapore (n = 503) and the United States (n = 505).

Vitamin d deficiency in children with cancer.

A limited number of small studies have examined the vitamin D status of pediatric oncology patients, and the results indicate an increased prevalence of hypovitaminosis. We conducted a cross-sectional study with the primary aim of describing the vitamin D status of our pediatric cancer patients and any associations with demographic characteristics. Our secondary aim was to compare this prevalence to that of a healthy population.

Can text messaging be used as an effective method for collecting quality and detailed evaluation data from students on clinical placements?

Background: Collecting timely evaluation from students on their clinical placements for quality assurance purposes is challenging. Prompt responses can help placement organisers improve the experience for the next cohort of students.

Aims: This paper examines the success and limitations of using text messages to collect anonymous, instant, and detailed evaluation from students on clinical placements.

'Geoengineering'--taking control of our planet's climate.

There is international consensus that 'dangerous' climate change must be avoided. Yet without radical changes in energy sources and usage and global economies, changes that so far society has been unable or unwilling to make, it seems highly likely that we will start to experience unacceptably damaging and/or societally disruptive global environmental change later this century. What actions can be taken to safeguard future environmental quality, ecosystems, agriculture, economy, and society? A new science--'geoengineering'--that until recently would have seemed pure science fiction, promises an alternative way of temporarily regaining control of climate.

Short-term effect of a protein load on appetite and food intake in diseased mildly undernourished elderly people.

Background & Aims: Malnutrition is a risk factor for mortality and various morbidities in the elderly. A low-energy intake often prevails and therapeutic interventions include the administration of dietary supplements, sometimes rich in proteins. We have tested the hypothesis that a protein-rich supplement inhibits appetite and decreases voluntary food intake.
