    Science Talent Search announces finalists

    For decades, leaders in science and technology have kicked off their careers with high school research projects for the Science Talent Search. This week, judges announced the finalists for the national competition's 60th anniversary year.

    Chosen from a field of 300 semifinalists, the 40 high school seniors represent just 2.5 percent of those who entered the 2001 Intel Science Talent...

    The End of Good Science?

    On his Web site, Pedro Merino reveals to the cybersurfing world that he cycles, swims, plays tennis, and likes classical music. He also notes that he likes to use the Internet to report his chemical research. That may not sound as cool as an extreme sport like helicopter skiing, but it's a practice so radical that it could alter the fabric of the chemistry community.

    Medicinal Mimicry

    Simply participating in a medical-research trial sometimes improves a person's health. That's why investigators use placebos—inert pills or other dummy treatments—and make both study participants and staff unaware of whether a person is receiving an active treatment or not. Anywhere from 10 to 100 percent of the people taking placebos in trials see their symptoms wane. In such a test, a drug...

    People on the go follow the flow

    It's easy to walk from the living room to the hallway, the hallway to the bathroom, and so on. Yet scientists have long argued about how people navigate to a destination.

    A virtual reality device that allows individuals to walk through a world in which the laws of optics systematically go awry may help settle this debate, a team of cognitive scientists reports in the February Nature...

    Teenage depression shows family ties

    Children and teenagers sometimes experience bouts of helplessness, hopelessness, and despair that are diagnosed as major depression. Researchers have been unable to determine whether depressed youths display an early version of adult depression or a different mood disorder, perhaps stemming from problems such as anxiety, delinquency, and substance abuse.

    There does appear to be a strong...

    Conductors single out sour side notes

    Experienced classical-music conductors wield their batons like master anglers, pulling musical keepers out of an orchestra's pool of instrumentalists. This impressive feat—which occurs only after many practice sessions leading up to a concert—requires maestros to monitor both the orchestra's overall performance and the contributions of specific violinists, oboists, trumpeters, and so on.

    Success clearing clogged arteries

    Angioplasties—procedures to open blocked arteries—have been successful about 10 percent more often in recent years than they were in the mid-1980s, and patients treated a few years ago were about 40 percent less likely to need later angioplasty or surgery than were patients a dozen years earlier.

    Using national registries, David O. Williams of Brown University in Providence, R.I., and...

    A sticky problem solved

    A small cut won't bleed for long because tiny blood cells called platelets stick together and trigger clots. Damaged blood vessels and red blood cells release a compound known as adenosine diphosphate, or ADP, which triggers the process that makes platelets sticky.

    Sometimes, however, overly reactive platelets are attracted to arteries damaged by fatty buildup. There, they form clots...
