| Engineers hand 'cognitive' control to underwater robots Posted: 08 May 2015 07:58 AM PDT For the last decade, scientists have deployed increasingly capable underwater robots to map and monitor pockets of the ocean to track the health of fisheries, and survey marine habitats and species. In general, such robots are effective at carrying out low-level tasks, specifically assigned to them by human engineers -- a tedious and time-consuming process for the engineers. Now a new programming approach gives robots more "cognitive" capabilities, enabling humans to specify high-level goals, while a robot performs high-level decision-making to figure out how to achieve these goals.  |
| More sex doesn't lead to increased happiness Posted: 08 May 2015 07:58 AM PDT Countless research and self-help books claim that having more sex will lead to increased happiness, based on the common finding that those having more sex are also happier. Scientists now report that simply having more sex did not make couples happier, in part because the increased frequency led to a decline in wanting for and enjoyment of sex.  |
| Cooperative video game play elicits pro-social behavior, research finds Posted: 08 May 2015 07:56 AM PDT A new study examined aggressive behavior between subjects playing games cooperatively, competitively and by themselves. It seems playing video games cooperatively with others can lead to widespread benefits by making players think helpful behaviors are valuable and commonplace.  |
| Traces of flowers placed on a Palaeolithic tomb Posted: 08 May 2015 06:15 AM PDT The burial of the so-called Red Lady, dating back to the Upper Palaeolithic, was discovered in El Mirón cave (Cantabria) in 2010. Unlike most Palaeolithic tombs this one is intact and has not been contaminated. Researchers have now anayzed the remains of fossilized pollen dating back more than 16,000 years ago and which appeared on the tomb.  |
| 'Make like a bat’: Two ears attuned to high frequencies help people find objects using echoes Posted: 08 May 2015 05:26 AM PDT The ability that some people have to use echoes to determine the position of an otherwise silent object, in a similar way to bats and dolphins, requires good high-pitch hearing in both ears, according to new research. This builds on recent research that demonstrated conclusively that some sighted and blind people could use echoes in this way. What wasn't clear until now was how important high-frequency hearing in both ears is.  |
