The brown marmorated stink bug tops the USDA's list of most invasive insects. Since arriving on the East Coast aboard a ship from Asia, they've spread to 40 states and threaten billions of dollars in crops. In this month's Environmental Outlook, we look at the biology and ecology of stink bugs and efforts to control their invasion.
Miniaturizing technology is really hard — gears, rotors, belts and pistons that work perfectly at human size just don't work very well at the small scale. So researchers are turning to insects for ideas about how to make tiny flying robots and cameras — and driving a new generation of gadgets.
For years, salmon farming has gotten a bad rap from marine biologists, who say the fish grown in open-ocean net pens generate pollution, disease and parasites. But now, a few salmon farms have moved on land. From an environmental standpoint, some scientists say, that's "a huge step forward."
Corn and soybean farmers not only survived last year's epic drought — thanks to crop insurance, they made bigger profits than they would have in a normal year, a new analysis finds. And a big chunk of those profits were provided through taxpayer subsidies.
The winter of 1609-1610 has been called the "starving time" for the hundreds of men and women who settled the English colony of Jamestown, Va. They ate their horses, their pets — and, apparently, at least one person. Scientists say human bones recovered from the site provide the first hard evidence that the colonists may have resorted to cannibalism.
