POPSA New State Of Mind But that view of the neurotransmitter was vastly oversimplified. What wasn’t yet clear was that dopamine is also a profoundly important source of information. It doesn’t merely let us take pleasure in the world; it allows us to understand the world.

POPSPaul Newman tells his family,I want to die at home It was reported last month that he had been readying their oldest child, Nell, to take over his Newman’s Own salad dressings company, the profits of which are given to a charitable foundation. He also has two daughters from his first marriage to Jackie Witte. Newman has so far declined to comment on his condition, apart from saying he is ‘doing nicely’. Rumours about his health surfaced in January. Three months ago, he withdrew from directing a production of

POPSComputer model of bees probes the hive mind Thenius believes the foragers may be picking up clues about the quality of sources from their interactions with receivers. If some foragers have found a bountiful new source, the receivers have more work to do, so average unloading times across all foragers increase. This delay might suggest the existence of a better nectar source than the one a given forager has been visiting. Similarly, receivers are sometimes already half-full from another bee's nectar when a new forager arrives, so a forager needs to unload to more than one receiver. If this occurs more frequently, it may also suggest that a richer nectar source has been found. To test this hypothesis, Thenius's team built a computer simulation of a hive containing 5000 independent virtual bees. Each forager started out visiting one of two different flower patches, but would switch destinations if it had to wait too long to be unloaded or was being serviced by too many receivers.

POPSArsenic-eating bacteria rewrite evolutionary history Oremland's team isolated and bred these bacteria in the lab. By growing them with with arsenite as the only possible food source, the researchers showed that the bacteria can indeed thrive. The results suggest that arsenic photosynthesis evolved at the same time, or even before, "normal" photosynthesis. Oremland says a similar mechanism might once have fuelled life on Mars or on Jupiter's moon Europa.

POPSAfghan Militants Butcher American Soldiers
I didn't say anything about it here or elsewhere because a.) I didn't know what the families knew, and b.) I couldn't confirm it with anyone else. As for the soldiers being alive when captured, I still don't know with certainty whether or not that's true or just battlefield rumor. But everything else my source told me has turned out to be correct. The New York Times explains in more detail: The three were identified as Sgt. First Class Matthew L. Hilton, 37, of Livonia, Mich., of the Michigan Army National Guard; and Sgt. First Class Joseph A. McKay, 51, of Brooklyn; and Specialist Mark C. Palmateer, 38, of Poughkeepsie, N.Y., both of them part of a reconnaissance, surveillance and target acquisition unit of the New York Army National Guard, according to a Pentagon news release. Their Afghan interpreter was 21-year-old Muhammad Fahim from Kabul, who had been working with the Americans for the last three years. His body was burned beyond recognition, his family said.
