"It’s the kind of scenario that might evolve in Hollywood: A college professor detects drug-resistance genes collecting in local wetlands, where they survive for weeks and are spread far and wide by seabirds.

But the discovery of extra-hardy DNA flourishing on the edge of San Diego isn’t science fiction. It’s the result of research by David Cummings, a microbiologist at Point Loma Nazarene University.

"Plants are flowering faster than scientists predicted in response to climate change, research in the United States showed on Wednesday, which could have devastating knock-on effects for food chains and ecosystems. Global warming is having a significant impact on hundreds of plant and animal species around the world, changing some breeding, migration and feeding patterns, scientists say."

"Some bomb-sniffing dogs trained to help fight terrorism are turning their olfactory attention toward a different scourge: Burmese pythons in Florida's Everglades National Park."

"Koalas are expected to be listed as a threatened species across parts of Australia from Monday, and some environment groups claim the government has excluded the marsupial from protection in certain areas due to mining interests."

"Where have all the bees gone? The question has vexed farmers, beekeepers, regulators and scientists since the fall of 2006, when U.S. bee populations began their mysterious decline."

"A new biotech corn developed by Dow AgroSciences could answer the prayers of U.S. farmers plagued by a fierce epidemic of super-weeds. Or it could trigger a flood of dangerous chemicals that may make weeds even more resistant and damage other important U.S. crops. Or, it could do both."

"In 2006, when beekeepers began to report that their hives were suffering from a mysterious affliction, a wide variety of theories were offered to explain what was going on. ... Over the last few weeks, several new studies have come out linking neonicotinoids to bee decline. As it happens, the studies are appearing just as 'Silent Spring,' Rachel Carson’s seminal study of the effect of pesticides on wildlife, is about to turn fifty: the work was first published as a three-part series in The New Yorker, in June, 1962. It’s hard to avoid the sense that we have all been here before, and that lessons were incompletely learned the first time around."

"New research shows that killer whales are inhaling bacteria, fungi and viruses once believed to be found only on land. Some of the pathogens are highly virulent. And some are even antibiotic-resistant."
