    Teaching methods go from lab to classroom

    Sure, students in the classroom have to remember facts, but they also have to apply them. Some research efforts to enhance learning zero in on methods to strengthen memory and recall, while others bolster students’ abilities to stay on task, think more fluidly and mentally track and juggle information.

    But there’s a catch. The science behind student learning is so far based on carefully...

    Ticks are here to stay. But scientists are finding ways to outsmart them

    Thanks, Holly Gaff. Soon, anyone straining to tweeze off a mid-back tick can find answers to the obvious question: What if humankind just went after the little bloodsuckers with killer robots?

    Gaff, who calls herself a mathematical eco­epidemiologist, at Old Dominion University in Norfolk, Va., is one of the few people collecting real field data on the efficacy of tick-slaying robots....

    Rendezvous with Pluto

    View timeline

    Tiny, far-flung Pluto is about to have a visitor — at least for a few hours.

    On July 14, NASA’s New Horizons spacecraft will reach the dwarf planet and try to learn all it can about Pluto and its five known moons. Then the probe will leave Pluto behind, vanishing into the frigid darkness beyond the planets.

    In its wake, New Horizons will introduce Earth to the...

    Online causes may attract more clicks than commitments

    The Save Darfur Cause on Facebook had all the makings of a slam dunk cyber success. More than a million people joined the social media site’s digital movement a few years ago to save the people of Sudan’s Darfur region from mass slaughter.    

    There was a hitch in Facebook’s humanitarian giddy-up, though: The vast majority of people who enlisted in the Save Darfur Cause recruited no one...

    The 3-D Printing Revolution

    Joshua Pearce takes unusual satisfaction in strolling through Walmart. The shelves laden with toys, household items, tools and clothing inspire in him a certain smugness, a pride in American entrepreneurship. But it’s not because Pearce admires the chain as an empire built by a self-made man. Pearce swells with pride at Walmart because the store is full of mass-manufactured objects that he...

    Scientists probe terrorist talk on 'Dark Web'

    VANCOUVER — Deep within the recesses of the Internet, extremists discuss and plot terrorist acts. But new mathematical tools that combine web crawling techniques, sophisticated algorithms and human expertise are gaining access to this “dark side” of the Web and may help predict and prevent violence.

    Researchers engaged in the “Dark Web Project,” a program started partly in response to...

    The Digital Camera Revolution

    Take a grainy, blurred image of a formless face or an illegible license plate, and with a few keystrokes the picture sharpens and the killer is caught — if you’re a crime-scene tech on TV. From Harrison Ford in Blade Runner to CSI, Criminal Minds and NCIS, the zoom-and-enhance maneuver has become such a staple of Hollywood dramas that it’s mocked with video montages on YouTube.

    App for analyzing leafy curves lets amateur botanists identify trees

    Peter Belhumeur just wanted to know what type of tree was outside his apartment. He scanned field guides, looking for willowlike leaves with a wavy, spiked edge, but he couldn’t find the right one. Neither could his neighbors.

    As it happened, though, he was building a tool designed to address just this problem.  Belhumeur is a computer scientist at Columbia University who has worked on...
