Alien animals, plants and microbes cost U.S. $123 billion a year, Cornell ecologists report

A few bad actors among the more than 30,000 non-indigenous species in the United States cost $123 billion a year in economic losses, Cornell University ecologists estimate. "It doesn't take many trouble-makers to cause tremendous damage," Cornell ecologist David Pimentel.

U.S. could feed 800 million people with grain that livestock eat, Cornell ecologist advises animal scientists

From one ecologist's perspective, the American system of farming grain-fed livestock consumes resources far out of proportion to the yield, accelerates soil erosion, affects world food supply and will be changing in the future.

Thanks to April Fools' Nor'easter, parts of New England acquire new monthly snowfall-total records

Mother Nature had its own April Fools' prank in store for the Northeast -- it took only the first day of this month to record the snowiest April ever for Boston, Worcester, Mass., and Providence, R.I., according to the Northeast Regional Climate Center at Cornell University.

Digging at the roots of physics at the Cornell Theory Center

Almost 50 years ago, physicists determined the value of one of the fundamental fixed values of physics, the fine structure constant, using quantum electrodynamics theory -- or did they?

Weird winter weather is good for bird diversity, thousands of FeederWatchers report in continentwide study

Last winter's mish-mash of weather sent bird-watchers to their field guides as species showed up where they're usually not. Documenting irruptions of seldom-seen species throughout North America.

Mountain gorilla diet could yield health secrets of impenetrable forest's salad bar Bacteria-fighting fruit is favorite item of Uganda's gorillas, Cornell phytochemist finds

For Cornell biologist John P. Berry, knowing the punch line to the joke, "Where does an 800-pound gorilla eat?" is not enough. Certainly, the mountain gorillas he studies in Uganda's Bwindi impenetrable forest eat wherever they want. Whatever, too.

Biological methods may be more effective than machines at controlling weeds, Cornell scientist says

Scientists and engineers have waged a long war on the Eurasian watermilfoil, a non-indigenous water weed that diminishes swimming, boating and the environment. Using standard mechanical means of harvesting the milfoil, winning the war looked bleak, but environmentally friendly biological control may be the answer.
