    Hubble grumble

    The cover type "Farewell to Hubble?" ("End of the Line for Hubble?" SN: 7/24/04, p. 56: End of the Line for Hubble?) makes me wonder why we haven't seen the headline "Farewell to the Current NASA Administrator?" The only reason I have heard for the cancellation of the planned servicing mission is "it's too dangerous." Almost anything worth accomplishing has some degree of danger...

    Dormant Cancer: Lack of a protein sends tumor cells to bed

    One standard approach to curing cancer is to kill off malignant cells, and doctors consider their treatment a success when no cancerous cells remain. However, many patients whose test results show no malignancy have their cancer reappear years later. New research suggests an explanation.

    Scientists working with mice find that when they crank up production of a protein called Myc, they...

    Change in the Weather? Wind farms might affect local climates

    Large groups of power-generating windmills could have a small but detectable influence on a region's climate, new analyses suggest.

    Windmills once were quaint several-story-high mechanisms that pumped water or ground grain. They've since evolved into sky-scraping behemoths that can each generate electrical power for more than 100 homes.

    Some modern turbines are 72...

    Fat Fuels PCB Damage: Diet influences toxic effects leading to heart disease

    Polychlorinated biphenyls (PCBs) have been associated with cancer for decades. Since the late 1990s, evidence has also linked the pollutants to cardiovascular disease among workers with long-term exposure to PCBs in electrical equipment. Researchers now report that experiments on mice have shown that corn oil, which is common in U.S. diets, can magnify a PCB's damage to cells lining blood...

    Hearing Better in the Dark: Blindness fuels ability to place distant sounds

    Whether they lose sight early or later in life, blind people estimate the location of many sounds more accurately than sighted individuals do, a new study finds. In lieu of visual cues, the blind typically learn to perceive subtle acoustic signals that help them navigate, concludes a research team led by neuroscientist Franco Lepore of the University of Montreal.

    Most studies of sound...
