    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....

    Gun research faces roadblocks and a dearth of data

    Buying a handgun in Connecticut means waiting — lots of waiting. First comes an eight-hour safety course. Then picking up an application at a local police department. Review of the application (which includes a background check and fingerprinting) can take up to eight weeks. If approved, the state issues a temporary permit, which the buyer trades in at state police headquarters for a permanent...

    Deep network

    Gas bubbles effervesce from a mound of muck on the seafloor in a deep submarine canyon off the west coast of Canada. Microbes beneath the sediment belch the bubbles after feasting on the ancient remains of algae, sea critters and their poop: a primordial stew that’s been simmering since long before humans walked the Earth.

    This gassy oasis attracts an odd collection of critters. Worms...

    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...

    De-papering environmental summits

    This week, the United Nations hosted a major conclave in Rio de Janeiro — the 2012 Conference on Sustainable Development. Widely referred to as Rio+20, its timing commemorated the 20th anniversary of the so-called Earth Summit in this Brazilian capital. As one token — but highly visible — gesture toward sustainability, the new event encouraged all attendees to shrink their paper footprints....

    Death of a Continent, Birth of an Ocean

    To those who live there, east Africa’s Afar region is “the place the devil plows.” One of the hottest and lowest areas on Earth, it is a landscape of baking desert and barren lava flows. To scientists, though, Afar means something more promising: geology in the raw.

    There, on the edge of Africa, the continent is splitting apart. Pulled inexorably by the...

    Reviving the taste of an Iron Age beer

    Early Celtic rulers of a community in what’s now southwestern Germany liked to party, staging elaborate feasts in a ceremonial center. The business side of their revelries was located in a nearby brewery capable of turning out large quantities of a beer with a dark, smoky, slightly sour taste, new evidence suggests.

    Six specially constructed ditches previously excavated at...

    Largest known prime number found

    Editor’s note: This story was originally posted on Science News online as a Math Trek column September 20.

    Here’s a number to savor: 243,112,609-1.

    Its size is mind-boggling. With nearly 13 million digits, it makes the number of atoms in the known universe seem negligible, a mere 80 digits.

    And its form is tidy and lovely: 2n-1.

    But its true beauty is...

    Here’s a number to savor: 243,112,609-1.

    Its size is mind-boggling. With nearly 13 million digits, it makes the number of atoms in the known universe seem negligible, a mere 80 digits.

    And its form is tidy and lovely: 2n-1.

    But its true beauty is far grander: It is a prime number. Indeed, it is the largest prime number ever found.
