| Posted: 10 May 2012 11:19 AM PDT A vast city built by the ancient Maya and discovered nearly a century ago is finally starting to yield its secrets. Excavating for the first time in the sprawling complex of Xultún in Guatemala's Petén region, archaeologists have uncovered a structure that contains what appears to be a work space for the town's scribe, its walls adorned with unique paintings -- one depicting a lineup of men in black uniforms -- and hundreds of scrawled numbers. Many are calculations relating to the Maya calendar. |
| Posted: 10 May 2012 11:19 AM PDT From tiny villages in developing nations to suburban kitchens in the U.S., dangerous strains of E. coli bacteria sicken millions of people each year – and kill untold numbers of children. Now, new research gives scientists a better understanding of what is going on in the diarrhea-wracked guts of its victims, and what might be done to prevent or treat it. |
| Posted: 10 May 2012 10:14 AM PDT Culture has long been proposed to be a distinguishing feature of the human species. However, an increasing amount of evidence from the field has shown that in several animals, differences in behaviors between populations actually reflect the presence of culture in these species. These studies have mainly come from populations that live far apart from each other which make it difficult to exclude ecological or genetic differences as being the underlying reasons for the observed behavioral differences. |
| Smart phones are changing real world privacy settings Posted: 10 May 2012 08:41 AM PDT Smartphone users have a radically different conception of behavior in public spaces than their conventional phone counterparts. They are more likely to reveal private information in public spaces, and less likely to believe that their digital conversations are irritating to those around them. |

| Five-limbed brittle stars move bilaterally, like people Posted: 10 May 2012 07:03 AM PDT Brittle stars and people have something in common: They move in fundamentally similar ways. Though not bilaterally symmetrical like humans and many other animals, brittle stars have come up with a mechanism to choose any of its five limbs to direct its movement on the seabed. It's as if each arm can be the creature's front, capable of locomotion and charting direction. |
| Chimpanzee uses innovative foresighted methods to fool humans Posted: 10 May 2012 07:02 AM PDT Chimpanzee Santino achieved international fame in 2009 for his habit of gathering stones and manufacturing concrete projectiles to throw at zoo visitors. A new study shows that Santino's innovativeness when he plans his stone-throwing is greater than researchers have previously observed. He not only gathers stones and manufactures projectiles in advance; he also finds innovative ways of fooling the visitors. |
