The American Association for the Advancement of Science (AAAS) is the world's largest general scientific society, and publisher of the journal, Science (www.sciencemag.org). AAAS was founded in 1848, and includes some 262 affiliated societies and academies of science, serving 10 million individuals. Science has the largest paid circulation of any peer-reviewed general science journal in the world, with an estimated total readership of one million. The non-profit AAAS (www.aaas.org) is open to all and fulfils its mission to 'advance science and serve society' through initiatives in science policy; international programs; science education; and more. |

A team of scientists in South Korea has isolated the first human embryonic stem cell lines specifically tailored to match the nuclear DNA of patients, both males and females of various ages, suffering from disease or spinal cord injury. The research is being released by the journal Science, which is published by AAAS, the non-profit science society, on the Science Express website. |

Photograph of 'Neolithic burial HAL2' from Halberstadt, Germany. This burial exemplifies the Linear Pottery culture of the first Central European farmers, who lived about 7,500 years ago. The banded pottery and the flexed position of the legs are hallmarks of this farming culture. |

Thin cut of a polar ice sample illuminated through two polarizing filters. Grain boundaries appear in rainbow colors, the gas bubbles enclosed in the ice are dark. The analysis of the gas composition in these bubbles permits the reconstruction of greenhouse gas concentrations of the past 650,000 years. |

A new antibiotic shows promise, thus far in mice, for treating tuberculosis much faster than current drugs do, scientists report. Additional evidence indicates that the antibiotic may work against multidrug-resistant strains of the tuberculosis bug. Studies in healthy human volunteers have indicated that the drug is safe for humans to take, and further human studies are currently underway. |

The discovery of strong evidence that Mars was once awash in potentially life-supporting water has been named as the Breakthrough of the Year by the journal Science and its publisher, AAAS, the nonprofit science society. The findings suggest that Mars was a wet, warm place that could have been capable of nurturing life billions of years ago, when life on Earth was getting its start. |

Prions, the misfolded proteins implicated in mad cow disease, have been discovered in kidney, pancreas and liver tissues of prion-infected mice with chronic inflammation. These findings highlight the possibility that prions in farm animals with ongoing inflammatory conditions could move from their known range, in nervous and lymphoid tissues, to unexpected organs. |

What if making dinner meant climbing to the top of a palm tree, brandishing one of the tree’s fronds and pounding the tree to make a tasty mush, all while standing on two feet? If it isn’t appetizing, it is an impressive use of tools and smarts that a population of chimpanzees in Guinea adopted to fill their bellies. |

Obese 'couch potatoes' sit more and walk less than lean 'couch potatoes' living in the same environment, according in the journal Science. These findings may be important for understanding the biology of obesity and how best to treat this worsening epidemic. |

Researchers at AAAS said that a saliva-based diagnostic is evolving to test for bacteria, viruses, illegal drug use, steroids, antibodies, DNA and RNA, potentially reducing the need for blood and urine testing. |

This cartoon portrays the collapse in cooperation as a result of those who don't contribute to but benefit from the efforts of others. Groups that sanction such free-riders stabilize cooperative behavior and outcompete those that do not. |

According to a report in the Science, scientists have identified a new component of the brain system that regulates body weight. A select population of neurons in the brain's hypothalamus senses changes in the body's fuel availability and, in turn, influences appetite and metabolism. |

Mice exposed to a common antidepressant, fluoxetine (Prozac), in early postnatal development exhibited symptoms of depression and anxiety-related emotional disorders in adulthood, according to a new study. The study has potential implications for the prescription of fluoxetine to pregnant women and young children, the researchers said. |

Three independent studies have identified a gene involved in a form of eye damage that is the leading cause of blindness in the elderly. This findings may lead to tests that would allow earlier detection of the disorder, known as age-related macular degeneration or AMD, which in turn may lead to better treatments. |

A new type of sensor offers the first step toward giving robotic hands the delicacy of the human touch. The device, described in Science, has tactile sensitivity comparable to that of human fingers and could be useful for the next generation of minimally invasive surgeries. |

Donald Kennedy, Science editor in chief, said Friday that the journal is closely monitoring a controversy that has emerged over a landmark embryonic stem cell paper. The journal has received a request for retraction from the lead authors, Woo Suk Hwang and Gerald Schatten, but Science is withholding action on that request until all 25 co-authors sign off on the request, Kennedy told reporters in a telephonic news conference. |

Bone marrow cells have shown a surprising ability to grow in heart, liver, nerve and other cells. These findings have stirred controversy, however, over whether bone marrow cells actually change their genetic program and become these new types of cells. Some researchers have found evidence suggesting that bone marrow cells simply fuse with cells in other organs without actually taking on a new identity. |

If your parents are smart, will you be? Can someone be genetically compelled to act rashly? As a relatively new but growing field, behavioral genetics seeks to understand how both genes and environment contribute to the variations in human behavior such as intelligence, lifestyle choices or even proclivity for violence. |
