Polar bears, it seems, haven't given up the good fight just yet. Researchers recently observed these animal diving for longer and further than ever before - a hint that the species might still be developing new adaptations to support their unusual lifestyle.
For a fish that takes up to 10 months to develop, researchers have new findings on how this Antarctic creature would fare in warmer water and elevated carbon.
Scientists studying vitellogenin--a protein found in all egg-laying species--including fish, poultry, reptiles, amphibians and other insects--have learned that queen bees naturally innoculate young. They think this opens doors to giving pollinator vaccines.
Half the world's salamanders live in North America, doing their essential job of consuming insects and being an important part of the food chain. Do we want them to go extinct, like the Netherlands' fire salamanders, prey to a fatal fungus that may arrive on imported pets?
All of the bees that died in Portland, Ore. were near linden trees, a type of tree often sprayed to control aphids and the insects' sticky residue.
June 29 is Global Tiger Day--a recognition of the big cats that began in 2010, after a global summit on the tiger in St. Petersburg, when tiger numbers worldwide were estimated at 3200.

Researcher have long known that squids are particularly good at manipulating light - reflecting what sunlight trickles down into the ocean's deeper depths in order to confuse predators, prey, and even to communicate. Now a team of scientists has determined just what kind of mechanisms make squids such masters of light - information that could prove useful even for engineers.
Nutritionists and other health experts will all tell you the same thing: eating fish can be very good for your health. However, did you know that even a salmon plague can treat cancer? It may sound ridiculous, but this is what some researchers are suggesting after the discovery of toxins in fish bacteria that can stop tumor growth in its tracks.
Jutting out of rock in a hiking area of Alaska's Talkeetna Mountains were the bones of an ancient, long-necked swimmer. A fossil-finder recently ran across them.
It turns out that trematodes and other parasitic flatworms live in larger numbers in temperate regions, contrary to the global norm of greater biodiversity in warm temperatures.
Finches that experienced stress hormones in food at a young age chose social networks outside of their immediate family, and didn't imitate parents' ways. Will their somewhat random socializing factor into the spread of bird flu?
The pesticide class associated with bee colony collapse is in 70% of pollen and honey samples in Massachusetts. How are the rest of our 49 states doing?
