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.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
