Dopamine and serotonin, two neurotransmitters in the central nervous system, are intimately involved in muscle control, memory, sleep, and emotional behavior. They are also linked to illnesses such as Parkinson’s disease and mood disorders. Now, regulation of longevity may be added to this list.
Three natural variants in the gene for DOPA decarboxylase (DDC), an enzyme required for the production of dopamine and serotonin, together accounted for 15 percent of the genetic contribution to variation in life span among strains of the fruit fly Drosophila melanogaster, according to recent research by geneticists at North Carolina State University.
“This is a surprisingly large effect for a gene affecting a complex trait, such as longevity or body size, which is typically controlled by many genes with relatively small effects,” said Dr. Trudy Mackay, William Neal Reynolds Professor of genetics at NC State and director of the study. Results of the study appear in the paper “Dopa decarboxylase affects variation in Drosophila longevity,” published in the July 27 online edition of Nature Genetics.

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...
