Toxic pollen from widely planted, genetically modified corn can kill monarch butterflies, Cornell study shows

An increasingly popular commercial corn, genetically engineered to produce a bacterial toxin to protect against corn pests, has an unwanted side effect: Its pollen kills monarch butterfly larvae in laboratory tests, according to a report by Cornell University researchers.

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

ITHACA, N.Y. -- 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. "Certainly, it was a very significant storm," said Keith Eggleston, climatologist at the center, describing what is being called the Great April Fools' Day Storm of 1997. It took only hours for a powerful Nor'easter to dump enough snow on many Northeastern locations to start setting records. "If this storm had occurred in any part of winter, it would have been a significant storm."

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?
