38 percent of state public health workers plan to leave the public health workforce by 2020 but it isn't just retirement, they want to get out of a health care system that is even more micromanaged and financially motivated that when HMOs and insurance companies were the big problem - government control. 

The article in Journal of Public Health Management and Practice (JPHMP) is based on the Public Health Workforce Interests and Needs Survey (PH WINS), the largest-ever study of the public health workforce.  

Vitamin D supplements have been linked tp everything but improved exercise performance in 2015 - and a preliminary study presented today at the Society for Endocrinology annual conference in Edinburgh took care of that. Plus claiming this supplement will lower the risk of heart disease.

Vitamin D, which is both a vitamin and a hormone, helps control levels of calcium and phosphate in the blood and is essential for the formation of bones and teeth. Sources of Vitamin D include oily fish and eggs, but it can be difficult to get enough through diet alone. Most people generate vitamin D by exposing their skin to ultraviolet B rays in sunlight.

For millennia, Greenland's ice sheet reflected sunlight back into space but satellite measurements in recent years suggest the bright surface is darkening, causing solar heat to be absorbed and surface melting to accelerate.

Some studies suggest this "dirty ice" or "dark snow" is caused by fallout from fossil fuel pollution and forest fires; soot or dust.

But a new study says the readings are just degrading satellite sensors and the ice sheet hasn't lost as much reflectivity as previously thought, and that black carbon and dust concentrations haven't increased significantly and are thus not responsible for darkening on the upper ice sheet.

A team of astronomers is proposing that huge spiral patterns seen around some newborn stars, merely a few million years old (about one percent our sun's age), may be evidence for the presence of giant unseen planets. This idea not only opens the door to a new method of planet detection, but also could offer a look into the early formative years of planet birth.

Though astronomers have cataloged thousands of planets orbiting other stars, the very earliest stages of planet formation are elusive because nascent planets are born and embedded inside vast, pancake-shaped disks of dust and gas encircling newborn stars, known as circumstellar disks.

Around 20 per cent of girls from ethnic minority backgrounds are not being vaccinated against the Human Papilloma Virus (HPV) because they feel they don't need it, according to a Cancer Research UK survey presented today at the National Cancer Research Institute (NCRI) Cancer Conference in Liverpool.

The authors say this is the first study done with an ethnically diverse group of girls to look at why they are not vaccinated, or do not complete the series of injections. Researchers found that 17 percent of girls from black backgrounds and 22 percent of girls from Asian backgrounds who hadn't been vaccinated said that they did not need the vaccination and the reasons they gave included that they did not expect to be sexually active before marriage. 

Diet diversity may be linked to lower diet quality and worse metabolic health, according to survey data from 6,814 participants in the Multi-Ethnic Study of Atherosclerosis, a study of whites, blacks, Hispanic-Americans and Chinese-Americans in the United States.

The authors looked at diet diversity through different measures. These included the total count (number of different foods eaten in a week), evenness (the distribution of calories across different foods consumed), and dissimilarity (the differences in food attributes relevant to metabolic health, such as fiber, sodium or trans-fat content).
