Princeton researchers develop method to better measure peoples quality of life
A new research method that quantifies peoples quality of life -- beyond how much money they make -- could lead to a national index of well-being, similar to key measures of economic health. The Day Reconstruction Method (DRM), developed by Princeton researchers and colleagues from three universities, creates an "enjoyment scale" by requiring people to record the previous days activities in a short diary form and describe their feelings about the experiences. The technique is more effective than current methods of measuring the well-being of individuals and of society, the researchers said in the Dec. 3 issue of Science.
The new tool will be used in an effort to calculate a "national well-being account," a measure similar to economic gauges such as the gross national product. The research team is working with the Gallup Organization to pilot a national telephone survey using the new method. "The potential value is tremendous," said Princeton economist Alan Krueger, who worked with psychologist Daniel Kahneman, a Nobel laureate, on the study. "Right now we use national income as our main indicator of well-being, but income is only a small contributor to life satisfaction. Ultimately, if our survey is successful and generates the type of data we hope, we would like to see the government implement our method to provide an ongoing measure of well-being in addition to national income."

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
