U.S. Surgeon General David Satcher says the nation is "underprepared" for bioterrorism but is making rapid steps forward. Satcher spoke by satellite video Tuesday at a conference sponsored by the Minnesota Department of Health.
The prospect of increased military spending in the wake of last week's terrorist attacks has prompted a dramatic rise in the stock prices of some defense contractors---including Edina-based Alliant Techsystems. The company makes ammunition and precision guided munitions that may be needed as the nation goes to a war footing.
The geology of southeast Minnesota lends itself to sinkholes, where surface water disappears into groundwater. With the advent of large-scale feedlots in the region, there's concern that drinking water is just a sinkhole away from contamination.
A State Fair game played on what was billed as the world's largest monopoly board has raised more than $105,000 to support four groups working for affordable housing in Minnesota.
Beginning in the late 1990s, pilots in ultra-light planes led successful migrations of Canada geese, trumpeter swans and sandhill cranes. Now they're hoping to use the same technique to save an endangered species: the whooping crane.
Once, a postage-stamp-sized butterfly known as the Karner Blue was found all across the Great Lakes states, from Minnesota to New York, but now its population has declined by 99 percent. The Karner Blue's last stronghold is in Wisconsin, where an unprecedented state-wide effort is underway to save it.
Almost everyone has a hobby or two. Occasionally, people's hobbies grow into consuming passions. That's what happened to Mark Mattison after he bought his first elk.
Two years ago, a Fourth of July windstorm swept through the Boundary Waters Canoe Area Wilderness with the force of a hurricane. Straight-line winds toppled tree trunks like dominoes, flattening more than a third of the million-acre wilderness. To many, the storm seemed like a catastrophe, but it's provided a rare opportunity for scientists to study how a wilderness recovers from a massive natural disturbance.
A Renville County hog farm has agreed to pay a $125,000 fine and put high-tech covers on all 14 of its manure holding lagoons. Representatives of the ValAdCo hog cooperative and the Minnesota Pollution Control Agency reached the agreement Thursday night after a day-long mediation session.
The Minnesota Pollution Control Agency's six-year-long search to find the cause of the state's widespread frog deformities appears to have come to a halt. Until this year, PCA researchers were at ground zero of an investigation that involved scientists nationwide. Now the agency's retreat is leaving what some scientists say is a critical hole in the effort to solve the mystery of the deformed frogs.
For the first time in 40 years, peregrine falcons are nesting and raising young on the cliffs along the upper Mississippi River. They're taking back nesting spots that have sat empty since peregrine falcons were nearly wiped out by the insecticide DDT. It's one of the final stages in the spectacular comeback of the once endangered birds.
The U.S. Department of the Interior now says that it opposes the removal of the Stillwater lift bridge after a new bridge opens. Its previous determination that the 1931 bridge be removed as environmental mitigation had driven a wedge between environmentalists and historic preservationists, and has been another hotly-contested issue in an already controversial project. For state transportation officials, however, keeping the bridge might just be too expensive.
What's next on the genetic front? Transgenic livestock. Already, scientists are developing goats, sheep and dairy cows with transplanted genes for use in laboratories. Those animals are producing human pharmaceuticals in their milk, athough the products have not yet been approved for commercial use.
Biologists on the upper Mississippi River are making a last ditch attempt to save a little-known endangered species: a small, mud-brown mussel known as the Higgins' Eye. Hoards of non-native zebra mussels infesting the Mississippi have devastated native mussel populations, and nearly wiped out the Higgins' Eye. Now, scientists are trying to evacuate the Higgins' Eye to tributaries of the upper Mississippi - places free of zebra mussels, where the native mussels can find refuge.
