Danish researchers found that sun exposure behaviors and personal characteristics are correlated with the dose of ultraviolet radiation (UVR) a person receives, according to a report in the February issue of The Archives of Dermatology, one of the JAMA/Archives journals.
UVR exposure is a well-known risk factor for developing skin cancer, according to the article. Guidelines of safe limits of UVR exposure have been issued by many international health organizations. These limits are determined using information on sun exposure collected by questionnaires, diaries and personal UVR dosimetry studies. Some UVR measuring devices (called dosimeters) can be affixed to the body or clothing and used to measure personal overall UVR exposure and cumulative UVR doses. To analyze individual sun exposure patterns, continuous UVR measurements need to be taken and matched to time of day and activity of the dosimeter wearer.
Elisabeth Thieden, M.Sc. (Pharm), of the University of Copenhagen, Denmark, and colleagues examined individual UVR dose patterns and sun exposure in 285 Danish volunteers with healthy skin ranging in age from 4 to 68 years. Participants in the study wore a dosimeter on their wrist to record UVR exposure and time every ten minutes.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
