For Marcel Proust, the taste of a madeleine conjured remembrance of the distant past. In todays multi-tasking, hyper-speed world, it can be a trick to remember what we did yesterday.
But a new method of reconstructing the previous days activities not only helps people remember how they spent their time, it also captures how they really felt about their activities. The technique, described in the Dec. 3 issue of Science, provides insight into what people actually enjoy and what kinds of factors affect how happy we are with our lives. Some of the findings confirm what we already know while others are counter-intuitive. The researchers assessed how people felt during 28 types of activities and found that intimate relations were the most enjoyable, while commuting was the least enjoyable.
More surprisingly, taking care of their children was also among the less enjoyable activities, although people generally report that their children are the greatest source of joy in their lives. "When people are asked how much they enjoy spending time with their kids they think of all the nice things---reading them a story, going to the zoo," said University of Michigan psychologist Norbert Schwarz, a co-author of the Science article. "But they dont take the other times into account, the times when they are trying to do something else and find the kids distracting. When we sample all the times that parents spend with their children, the picture is less positive than parents expect. On the other hand, we also find that people enjoy spending time with their relatives much more than they usually assume."

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
