    Ideal Justice: Mathematicians judge the Supreme Court

    The U.S. Supreme Court–already in the news this week for its decisions on affirmative action–is highlighted in a scientific journal. The court is driven by politics far less than Congress is, a new analysis suggests.

    Easy Repair: Novel structural model heals with heat

    The capacity of biological tissues to heal after being wounded is one of their most enviable traits. In recent years, materials scientists have been trying to emulate this capability by developing synthetic self-healing or easily mendable materials for products ranging from aerospace parts to athletic gear (SN: 2/17/01, p. 101: Scientists develop self-healing composites).

    Solar Terrain: Revealing the sun's complex topography

    The sun is no smoothie. The sharpest images of the sun ever taken, released last week, show a rugged surface with gargantuan mesas and valleys formed of scalding gas.

    The sun's surface is textured with short-lived structures, known as granules, each as big as Texas. "Up until now, we saw granules as flat pancakes with no apparent height or detailed structure," says lead...

    Prevention in a Pill? Baldness drug might avert prostate cancer

    The drug finasteride plays a curious dual role: It can help a man grow back thinning hair and also alleviate urinary problems. The drug achieves both effects by ratcheting down production of dihydrotestosterone, a hormone linked to male pattern baldness and enlargement of the prostate.
