The study looked at prevalence of tinnitus and to what degree it is hereditary. Prevalence of tinnitus was 15.1 percent, which correlates well with findings from other countries.
Tinnitus is a symptom with a variety of underlying causes, such as impaired hearing or exposure to noise and medicines.Surprisingly low heritability
"Such a low heritability is a surprising find because most other diseases studied earlier have been more or less hereditary. We had expected that genetics and the environment would be roughly as important as each other," said Dr Ellen Kvestad at the Division for Mental Health at the Norwegian Institute of Public Health.
The article "Low heritability of tinnitus" was recently published in Archives of Otolaryngology – Head and Neck Surgery (see link below).Sub-groups of tinnitus can have higher heredity
"Our findings do not mean that genes are not important for some forms of tinnitus. Some sub-groups of tinnitus with certain underlying causes can have higher heritability. From our findings alone, resources cannot be allocated to find specific genes that code for tinnitus in general, added Kvestad.About the study

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.

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...
