| NASA Cassini images may reveal birth of a Saturn moon Posted: 14 Apr 2014 03:03 PM PDT NASA's Cassini spacecraft has documented the formation of a small icy object within the rings of Saturn that may be a new moon, and may also provide clues to the formation of the planet's known moons. |
| We're over the hill at 24, study says Posted: 14 Apr 2014 02:22 PM PDT It's a hard pill to swallow, but if you're over 24 years of age you've already reached your peak in terms of your cognitive motor performance, according to a new study. In one of the first social science experiments to rest on big data, the researchers investigate when we start to experience an age-related decline in our cognitive motor skills and how we compensate for that. |
| Cosmic slurp: Supercomputers help astronomers understand and predict how black holes swallow stars Posted: 14 Apr 2014 12:08 PM PDT A 'tidal disruption' occurs when a star orbits too close to a black hole and gets usurped. Researchers are using supercomputers to simulate tidal disruptions to better understand the dynamics of the process. Doing so will help astronomers find many more possible candidates of tidal disruptions in sky surveys and reveal details of how stars and black holes interact. |
| Wolves at the door: Study finds recent wolf-dog hybridization in Caucasus region Posted: 14 Apr 2014 06:21 AM PDT Hybridization of wolves with shepherd dogs in the Caucasus region might be more common, and more recent, than previously thought, according to new research. Scientists found recent hybrid ancestry in about ten percent of the dogs and wolves sampled. About two to three percent of the sampled wolves and dogs were identified as first-generation hybrids. |
| Posted: 14 Apr 2014 06:20 AM PDT The true extent of poor pupil behavior in schools is seriously underestimated, according to an academic. The research raises the question of the extent to which there is a right to learn in classrooms. The researcher argues that behavior cannot be interpreted as satisfactory if some pupils are impeding the learning of others and if teachers are not able to teach the class in a way that focuses primarily on optimizing pupil learning rather than on control issues. |
| Posted: 14 Apr 2014 06:20 AM PDT The meeting between a Neanderthal and one of the first humans, which we used to picture in our minds, did not happen on the Iberian Peninsula. That is the conclusion reached by an scientists after redoing the dating of the remains in three caves located on the route through the Pyrenees of the first beings of our species: L'Arbreda, Labeko Koba and La Viña. |
| Dual role of carbon dioxide in photosynthesis: Pioneering findings Posted: 13 Apr 2014 12:40 PM PDT Carbon dioxide, in its ionic form bicarbonate, has a regulating function in the splitting of water in photosynthesis, researchers have found. This means that carbon dioxide has an additional role to being reduced to sugar. The pioneering work opens up a new research field where researchers can investigate possible biological and ecological consequences of the dual role of carbon dioxide. |
| Taking iron improves women's exercise performance, study shows Posted: 11 Apr 2014 06:23 AM PDT Women who take iron supplements experience a marked improvement in their exercise performance, a new study shows. Iron supplementation improved women's exercise performance, in terms of both the highest level they could achieve at 100% exertion (maximal capacity) and their exercise efficiency at a submaximal exertion. Women who were given iron were able to perform a given exercise using a lower heart rate and at a higher efficiency. |
| 'Body hack' app by math researchers shortcuts jet-lag recovery Posted: 10 Apr 2014 04:46 PM PDT A different kind of jet-lag mobile app released today by mathematicians reveals previously unknown shortcuts that can help travelers snap their internal clocks to new time zones as efficiently as possible. |
