| Scientists slow down the speed of light travelling in free space Posted: 23 Jan 2015 11:41 AM PST Scientists have managed to slow photons in free space for the first time. They have demonstrated that applying a mask to an optical beam to give photons a spatial structure can reduce their speed. |
| Lucid dreams and metacognition: Awareness of thinking; awareness of dreaming Posted: 23 Jan 2015 10:51 AM PST To control one's dreams and to live 'out there' what is impossible in real life -- a truly tempting idea. Some persons -- so-called lucid dreamers -- can do this. Researchers have discovered that the brain area which enables self-reflection is larger in lucid dreamers. Thus, lucid dreamers are possibly also more self-reflecting when being awake. |
| Climate affects development of human speech Posted: 23 Jan 2015 07:25 AM PST A correlation between climate and the evolution of language has been uncovered by researchers. To find a relationship between the climate and the evolution of language, one needs to discover an association between the environment and vocal sounds that is consistent throughout the world and present in different languages. And that is precisely what a group of researchers has done. |
| How does the universe creates reason, morality? Posted: 23 Jan 2015 07:22 AM PST Recent developments in science are beginning to suggest that the universe naturally produces complexity. The emergence of life in general and perhaps even rational life, with its associated technological culture, may be extremely common, argues a scientist. |
| Yes, black holes exist in gravitational theories with unbounded speeds of propagation Posted: 23 Jan 2015 07:22 AM PST Gravitational theories with broken Lorentz invariance have attracted a great deal of interest as they provide a test-bed of LI and offer a mechanism to improve their ultraviolet behavior, so that the theories may be renormalizable. However in such theories, particles can travel with arbitrary velocities and black holes may not exist at all. In contrast to this expectation, it has been shown that an absolute horizon exists, which traps signals despite infinitely large velocities. |
| Mothers don't speak so clearly to their babies Posted: 23 Jan 2015 07:20 AM PST People have a distinctive way of talking to babies and small children: We speak more slowly, using a sing-song voice, and tend to use cutesy words like "tummy". While we might be inclined to think that we talk this way because it is easier for children to understand, new research suggests that, surprisingly, mothers may actually speak less clearly to their infants than they do to adults. |
| Gas variations are suggestive of seasons on comet Chury Posted: 22 Jan 2015 11:18 AM PST Comet 67P/Churyumov-Gerasimenko continues to reveal more of its secrets: Researchers have detected considerable variations in the gas escaping from the comet. This could amount to seasonal changes on the tiny celestial body. Meanwhile, the camera OSIRIS on board the Rosetta comet probe is revealing new details of the surface of Chury. |
