<jats:p> <jats:italic>Science</jats:italic> 's daily online news site <jats:italic>Science</jats:italic> NOW turns 15 this week. A 25-year struggle to sell genetically engineered "blue" roses in the United States took a big step forward last week. Right-wing Italians seem to naturally track the gaze of those in power, says a social neuroscientist. And this week's numbers quantify the air miles of the average astronomer and the thickness of snow on parts of Saturn's moon Enceladus. </jats:p>

<jats:p>This week's Newsmakers are a group of scientists who have squeezed a reproduction of the entire periodic table onto a human hair; Darryl Gwynne and David Rentz, who have won a 2011 Ig Nobel Prize for their study of beetles that mate with beer bottles; and Judy Mikovits, champion of the controversial theory that XMRV, a mouse retrovirus, had links to chronic fatigue syndrome, who was fired on 29 September.</jats:p>

<jats:p>Researchers have found a way to use human oocytes to reprogram adult cells, allowing them to form early embryos that can give rise to embryonic stem cells.</jats:p>

<jats:p>A steady supply of healthy human oocytes allowed one lab to set up a systematic study of human nuclear transfer, which has now brought scientists significantly closer to understanding why most attempts have so far failed.</jats:p>

<jats:p> Joe Selby is preparing to launch PCORI, the Patient-Centered Outcomes Research Institute. He met with <jats:italic>Science</jats:italic> last week to talk about PCORI's agenda, the tension in its mandate, and plans to involve patients in designing and reviewing research. </jats:p>

<jats:p>Researchers reported at a meeting last week that they may have reached a prized goal in gene therapy: lowering the risk of uncontrolled bleeding in patients with hemophilia.</jats:p>

<jats:p>Three researchers will share the Nobel Prize in physics for the dramatic observation that the universe's expansion is speeding up, which has changed the conceptual landscape in cosmology, astronomy, and particle physics.</jats:p>

<jats:p>This year's Nobel Prize in physiology or medicine honors three scientists who unraveled key details of how the immune system becomes activated. But the tragic death of one of the winners grabbed most of the attention.</jats:p>
