    See where Clinton and Trump stand on science

    Hillary Clinton’s “I believe in science” declaration aside, science has not played a starring role in the 2016 presidential election. Far from it. For the most part, the candidates’ science policies have trickled out in dribs and drabs, and in varying degrees of detail — talking points on a website here, a passing comment in response to a spur-of-the-moment question there.

    Yet science...

    Nanoparticles in foods raise safety questions

    It seemed like a small thing when Paul Westerhoff’s 8-year-old son appeared, with his tongue and lips coated bright white. The boy had just polished off a giant Gobstopper, a confectionery made of sugary, melt-in-the-mouth layers. Curious about the white coating, Westerhoff, an environmental engineer, pored over the jawbreaker’s contents and discovered just how incredibly small the matter was...

    Sam Ting tries to expose dark matter's mysteries

    In the near vacuum of outer space, each rare morsel of matter tells a story. A speedy proton may have been propelled by the shock wave of an exploding star. A stray electron may have teetered on the precipice of a black hole, only to be flung away in a powerful jet of searing gas.

    Since 2011, the International Space Station has housed an experiment that aims to decipher those origin...

    When Networks Network

    Half a dozen times each night, your slumbering body performs a remarkable feat of coordination.

    During the deepest throes of sleep, the body’s support systems run on their own timetables. Nerve cells hum along in your brain, their chitchat generating slow waves that signal sleep’s nether stages. Yet, like buses and trains with overlapping routes but...

    Ballot Roulette

    Two months ago, in primaries for governor and congressional and state legislative seats in Maryland, many trips to the polls became painful experiences. At hundreds of precincts in Montgomery County, for instance, new touch-screen voting machines sat useless for lack of plastic authorization cards needed to operate them. In many polling places, electronic poll books with lists of eligible...

    How Advertising Is Becoming Child's Play

    Not long ago, food advertising appeared primarily in newspapers, magazines, and television. Today, though, manufacturers are embracing new media to ever more effectively target their youngest consumers: children. A new study conducted for the Henry J. Kaiser Family Foundation analyzes how these companies are feeding their messages to tots.

    The number of Web sites hosting pages for...

    Cultivating Revolutions

    Nearly 80 years ago, the British archaeologist V. Gordon Childe championed a theory of what he called a revolution in food production during the Neolithic age. Childe proposed that hunting-and-gathering groups in the Middle East had been the first people to grow crops, raise animals for food, and live year-round in villages—around 10,000 years ago. In his scenario, farmers then spread into...

    Creepy-Crawly Care

    Pamela Mitchell is no stranger to modern medical care. Now 52, the former waitress from Akron, Ohio, began getting regular insulin injections at the age of 10, after she was diagnosed with type 1 diabetes. Twenty years ago, she received a life-saving kidney donation from her brother. In 2001, Mitchell faced yet another harrowing health threat. An infected cut on her left foot had turned into...

    The Case for DDT

    The pesticide DDT has a long and checkered history. Today, it evokes particularly contentious argument. Though environmentalists have come to demand this poison's elimination from the face of the Earth, some tropical-disease specialists laud DDT as an irreplaceable weapon in their fight against malaria. Which view prevails may be a life-and-death matter for nearly a half-billion people.

    Southern Reindeer Folk

    Paula DePriest was thrilled when she finally got the chance to see the species that she studies as they were being chewed up by the grazer for which they're named. She didn't even mind having to go halfway around the world and travel via uncomfortable means to a valley in northern Mongolia. A biologist at the Smithsonian Institution in Washington, D.C., DePriest studies lichens, especially...
