| Dietary recommendations may be tied to increased greenhouse gas emissions Posted: 05 Sep 2014 09:27 AM PDT If Americans altered their menus to conform to federal dietary recommendations, emissions of heat-trapping greenhouse gases tied to agricultural production could increase significantly, according to a new study. |
| Magnetic nanocubes self-assemble into helical superstructures Posted: 04 Sep 2014 03:36 PM PDT Nanochemists have found that magnetite nanocubes can self-assemble into helical superstructures under certain conditions; theoretical chemists simulated the phenomenon and explained the conditions under which it can occur. |
| 3-D film no more effective in evoking emotion than 2-D Posted: 04 Sep 2014 11:18 AM PDT Researchers have examined whether 3-D film is more effective than 2-D when used as a research method for evoking emotion. Both were effective, and 3-D did not add incremental benefit over 2-D, with implications for emotional research as well as entertainment. |
| Nano-pea pod model widens electronics applications Posted: 04 Sep 2014 06:27 AM PDT A new theoretical model explains how a nanostructure, such as the nano-pea pod, can exhibit localized electrons. Periodic chain-like nanostructures are widely used in nanoelectronics. Typically, chain elements include the likes of quantum rings, quantum dots, or quantum graphs. Such a structure enables electrons to move along the chain, in theory, indefinitely. The trouble is that some applications require localized electrons —- these are no longer in a continuous energy spectrum but in a discrete energy spectrum, instead. |
| Lead and cadmium found in some chocolate bought in Brazil Posted: 03 Sep 2014 07:58 AM PDT Scientists have found that commercial samples of chocolate purchased in Brazil contain varying levels of lead and cadmium, which can cause health problems, and that those levels are linked to how much cocoa a product contains. |
| Enjoying the possibility of defeat: Suspense, uncertainty predict how much players enjoy a game Posted: 03 Sep 2014 07:54 AM PDT Winning isn't everything, and in fact can even be a bit boring. Some people actually enjoy a game of tennis or poker more if their mettle is tested by a strong opponent -- regardless of the outcome. It's the suspense and uncertainty of a close game that often brings them back for more, says a research team. |
| New program to evaluate prominent individuals' personalities Posted: 02 Sep 2014 12:11 PM PDT A new program has been developed that automates classification of personality traits of prominent individuals -- both friend and foe. The new computer-supported methodology for personality profiling uses "vector semantics." This involves constructing a number of vectors representing personality dimensions and disorders and measuring the similarity with texts written by the human subject. |
