    Researchers Report Cloning Advance For Producing Stem Cells

    Scientists reported this week in the journal Cell that they had used somatic cell nuclear transfer techniques to create a source of embryonic stem cells from the skin cells of a patient. George Daley, director of the stem cell transplantation program at Boston Children's Hospital, and Josephine Johnston of the Hastings Center discuss the research.
  • After President Obama overturned Bush-era policy restricting federal funding of embryonic stem cell research in 2009, Nebraska Right to Life led a protest of the research outside the University of Nebraska regents' meeting.

    Cloning, Stem Cells Long Mired In Legislative Gridlock

    The news that scientists have successfully cloned a human embryo seems almost certain to rekindle a political fight that has raged, on and off, since the creation of Dolly the sheep. It's a fight that has, over the past decade and a half, produced a lot of heat and light and not a lot of policy.

    With Rising Seas, America's Birthplace Could Disappear

    By the end of the century, ocean levels could rise by 2 or 3 feet. That's enough to flood the colonists' first settlement at Jamestown, Va. And it's putting pressure on archaeologists to get as many artifacts out of the ground as quickly as possible — before it's too late.

    Could You Talk To A Caveman? Scientists Say It's Possible

    Researchers at the University of Reading are speculating that today's languages share a common root dating as far back as the last Ice Age. Words like "mother," "man" and "ashes" are categorized as "ultraconserved," meaning they are survivors of a lost language from which many modern tongues are descended.

    Microexpressions: More Than Meets The Eye

    David Matsumoto, a psychology professor at San Francisco State University, trains national security officials and police officers to recognize "microexpressions"--fleeting, split-second flashes of emotion across someone's face. Matsumoto says those subtle cues may reveal how an interview subject is feeling, helping officials to hone their line of questioning.

    The Myth Of Multitasking

    How long can you go without checking email, or glancing at your smartphone? Clifford Nass, a psychology professor at Stanford University, says today's nonstop multitasking actually wastes more time than it saves--and he says there's evidence it may be killing our concentration and creativity too.
  • One contemporary analysis links the increase in gender equality in a society with increased sexual empowerment of women and less sexual coercion. But there's more to it than that.

    What Does 'Sexual Coercion' Say About A Society?

    Anthropologists have long documented the differences in the extent of sexual coercion — including rape — in different human societies. But is it a vestige of evolutionary history, indicative of cultural activity or governed by power dynamics between females and males?

    Living Inside the Box

    David Boyle and Michele Bertomen wanted to build their own house on a 20 by 40 foot lot they purchased in Brooklyn. Bertomen, an architect, drew up plans and the bid was over $300,000. Inspired by Bertomen's students at New York Institute of Technology, the couple built their house from five shipping containers, which cost a few thousand dollars a piece.

    Bones Tell Tale Of Desperation Among The Starving At Jamestown

    The winter of 1609-1610 has been called the "starving time" for the hundreds of men and women who settled the English colony of Jamestown, Va. They ate their horses, their pets — and, apparently, at least one person. Scientists say human bones recovered from the site provide the first hard evidence that the colonists may have resorted to cannibalism.

    Big Sibling's Big Influence: Some Behaviors Run In The Family

    Psychologists have long known that children often model their behavior on the actions of parents or peers. But science has only recently begun to measure the influence of siblings. An older brother's or sister's behavior can be very contagious, it turns out — for good and for bad.

    'Zoobiquity': What Humans Can Learn From Animal Illness

    Animals and humans have a lot in common, including some of the health problems that plague them. In her book Zoobiquity, Dr. Barbara Natterson-Horowitz explores how studying animal illness — from cancer to sexual dysfunction — can help us better understand human health.
