The ant article's interesting, Amos.

But this one, also from physorg.com, is scary.

GM crop creates a 'superweed'

Genes from a genetically modified crop trial transferred into local wild plants, creating an herbicide-resistant "superweed," the Guardian reported Monday.

The newspaper said the cross-fertilization between GM oilseed rape, a brassica, and a distantly related plant, charlock, had previously been discounted as virtually impossible by scientists. The "superweed" was found during a follow up to the government's three-year trials of GM crops that ended two years ago.

When scientists treated the new form of charlock with an herbicide, nothing happened. And when seeds were taken from other weeds in the oilseed rape field, researchers found two other plants -- both wild turnips -- were also herbicide resistant.

The findings were posted last week on the Web site of the Center for Ecology and Hydrology -- a British governmental research station.

Incidentally, the article seems to presuppose that anyone who reads it already knows a few fundamentals about GM crops. What it doesn't explain is that many GM crops are engineered to be herbicide resistant so that non-selective herbicides can be sprayed over the entire field to kill weeds without damaging the crops.
