As the definition of adulthood has shifted in this country and young people are living with their parents even into their 20's, one group has been mostly left behind in this phenomenon: thousands of people who grow up in foster care. |

How land-living animals evolved from fish has long been a scientific puzzle. An important part of the mystery is the transformation of the fins of fish into the arms and legs of humans’ ancestors. |

Advertisements like those created by the state of Washington Department of Health, may have contributed to a decline in secondhand smoke in households, as did the restrictions on smoking in public places. |

According to a new study, eating half a bar of dark chocolate each day may lower high blood pressure though experts cautioned that the results should not be read as an invitation for chocoholics to pig out. |

David Mazziotti, University quantum chemist has proposed a new research tool that could help scientists more rapidly solve problems in atmospheric chemistry, combustion, medicine and other areas of research where the behavior of electrons plays a key role. |

Researchers have reported new findings that show genes that regulate brain development and function evolved much more rapidly in humans than in nonhuman primates and other mammals because of natural selection processes unique to the human lineage. |

The University of Chicago feels far from the Midwest's farms, but experiments at the Hyde Park campus could prove useful to corn and grain growers. |

Black holes, remnants of exploded stars and other exotic celestial objects emit streams of gamma rays that carry trillions of times more energy across the universe than visible light. Scott Wakely considers gamma rays the juiciest portion of the electromagnetic spectrum. |

A scientist at University of Chicago and colleagues say they've found the best way to avoid becoming a fossil is to be small and live in deep, tropical water. The four paleontologists who have published a detailed, global study of clam preservation say their work is intended to enhance evolutionary studies by determining what's missing from the fossil record and why. |

A pioneering University of Chicago research team reported that female rodents handle stress much better than males, which may hint at why women seem better able to survive social isolation than men. |

Nature apparently thinks you can, according to two University of Chicago studies providing the first scientific evidence that the human brain is still evolving, a process that may ultimately increase people's capacity to grow smarter. |
|

Researchers say that two genes involved in determining the size of the human brain have undergone substantial evolution in the last 60,000 years, leading to the surprising suggestion that the brain is still undergoing rapid evolution. |

Fermi National Accelerator Laboratory Physicists have reported what would seem to set a new standard for vacillation: a subatomic particle that reverses identity three trillion times a second, switching into its upside-down mirror-image evil-twin antimatter opposite and then back again. |

A comprehensive scan of the human genome finds that hundreds of our genes have undergone positive natural selection during the past 10,000 years of human evolution. |

For three decades scientists have known that humans and chimpanzees share 99 percent of the same genes, but they have been at a loss to explain what causes the two to be so obviously different physically, behaviorally and mentally. |

Despite recent moves by the federal government to build drug stockpiles for a possible outbreak of avian flu, some experts say the plans so far have neglected a key possibility: What if a pandemic strikes before the stockpiles are in place? |

A groundbreaking international sex survey reveals that couples in Western countries are the most sexually satisfied, while countries in the East appear to be less satisfied. |

A University of Chicago physics professor is among a team of researchers who've converted three atoms into a special state of matter. |

A University of Chicago study has found impotence also can be a warning sign for heart disease. Researchers found the link between impotence and heart disease is stronger than that of any other known risk factor, including smoking, family history and high blood pressure. |

When Denise Faustman announced that she had cured mice of diabetes, funders didn't exactly beat a path to her door, and colleagues didn't shower her with hosannas. |

Severe feelings of social isolation are associated with as much as a 30 mmHg rise in a person's systolic blood pressure by the age of 65, which could easily push their systolic blood pressure over 150 mmHg, the medical definition of hypertension. |

According to a study, a look at the medical records of Civil War soldiers suggests post-traumatic stress disorder existed back then, too. |

Martha Yasso, like many mothers of young children, was tired all the time, tired that whenever her 3-year-old son went down for a nap, she grabbed the chance to rest as well. But even with those precious extra minutes of sleep, she was still so exhausted by late afternoon that she could barely keep her eyes open. |

According to a new study that spotlights the severe personal problems afflicting the poorest families, several years into Wisconsin's stringent welfare-to-work program, which helped reduce welfare rolls in the state by 80 percent, the remaining welfare recipients fared poorly, seldom finding steady jobs or stable lives. |
