Both nature and nurture -- genetic makeup and the environment experienced through life -- combine to influence health and well-being, Duke University Medical Center researchers and their colleagues have determined in four new studies. The researchers showed that peoples genes play a key role in how they respond both biologically and psychologically to stress in their environment.
The researchers presented four studies that examine genetics and the environment on Thursday, March 2, 2006, as part of a symposium organized by Duke researchers at the American Psychosomatic Society annual meeting in Denver. The studies were conducted at Vrije Universiteit in Holland, the Medical College of Georgia and Duke. The studies were funded by the National Institute on Aging and the National Heart Lung and Blood Institute.
Two studies from Duke evaluated effects of a particular mutation in the gene that makes monoamine oxidase-A (MAOA-uVNTR), an enzyme responsible for breaking down serotonin as well as other neurotransmitters in the brain. One form of this mutation causes the gene to make more of the enzyme, while the other form results in less production of enzyme.

Innsbruck quantum physicists have constructed a diode for magnetic fields and then tested it in the laboratory. The device, developed by the research groups led by the theorist Oriol Romero-Isart and the experimental physicist Gerhard Kirchmair, could open up a number of new applications.
Electric diodes are essential electronic components that conduct electricity in one direction but prevent conduction in the opposite one. They are found at the...
Max Planck researchers revel the nano-structure of molecular trains and the reason for smooth transport in cellular antennas.
Moving around, sensing the extracellular environment, and signaling to other cells are important for a cell to function properly. Responsible for those tasks...
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...
