 | Mantis shrimp can see the world in a way that had never been observed in any animal before, researchers report in the March 20th Current Biology, a Cell Press publication. The discovery-which marks the fourth type of visual system-suggests that the ability to perceive circular polarized light may lend mantis shrimp a secret mode of communication. ...> Full Article |
 | Ferrets, frogs and finches are becoming more common as pets, but the list of unusual species adopted into human households now includes some of the most exotic creatures on the planet. The trade in exotic pets has become a multi-billion dollar enterprise, but expansion of the industry sometimes outpaces veterinary knowledge of how to treat the maladies that afflict these unusual animals. ...> Full Article |
 | Rain falling on snow sounds like a relatively harmless weather event, but when it happens in the far north it can mean lingering death for reindeer, musk oxen and other animals that normally graze on the Arctic tundra. ...> Full Article |
 | Researchers have discovered that our visual system can estimate number, just as it can guess size or speed. And they believe we see number in the same way we see colour and shape, and that other species, even bees, can do so too. ...> Full Article |
 | Male songbirds produce a subtly different tune when they are courting a female than when they are singing on their own. Now, new research offers a window into the effect this has on females, showing they have an ear for detail. The finding provides insights not only into the intricacies of songbird attraction and devotion but also into the way in which the brain develops and responds to social cues, in birds - and humans. ...> Full Article |

 | Take a deer's body, attach a camel's head and add a Jimmy Durante nose, and you have a saiga - the odd-ball antelope with the enormous schnoz that lives on the isolated steppes of Central Asia. Unfortunately, they are as endangered as they are strange-looking due to over-hunting ...> Full Article |

 | The announcement of the discovery of a new bird comes with a twist: It's a white-eye, but its eye isn't white. Still, what this new bird lacks in literal qualities it makes up for as one of the surprises that nature still has tucked away in little-explored corners of the world. ...> Full Article |

 | Nature is full of examples of creatures that try to look as big as possible in an effort to scare away potential predators. But to avoid being eaten alive the larvae of sand dollars appear to have a different strategy, in a way exchanging a dollar for a couple of dimes. ...> Full Article |

The organic soup that spawned life on Earth may have gotten generous helpings from outer space, according to a new study. Scientists at the Carnegie Institution have discovered concentrations of amino acids in two meteorites that are more than ten times higher than levels previously measured in other similar meteorites. This result suggests that the early solar system was far richer in the organic building blocks of life than scientists had thought, and that fallout from space may have spiked Earth's primordial broth.

 | The strongest creature in the world, the Hercules Beetle, has a colour-changing trick that scientists have long sought to understand. Research published today, Tuesday, 11 March, in the New Journal of Physics, details an investigation into the structure of the specie's peculiar protective shell which could aid design of 'intelligent materials'. ...> Full Article |

 | The first study of how individual wandering albatrosses find food shows that the birds rely heavily on their sense of smell. The birds can pick up a scent from several miles away, U.S. and French researchers have found. ...> Full Article |
 | A long-term study by the Wildlife Conservation Society, the BioDiversity Research Institute, and other organizations has found and confirmed that environmental mercury-much of which comes from human-generated emissions-is impacting both the health and reproductive success of common loons in the Northeast. ...> Full Article |

 | Like many northerners who head south to warmer climates for the winter, many Northern right whales also head south in November and stay into April. Their destination is the only known calving ground for this rare and endangered population-the waters off Florida, Georgia and South Carolina. When they arrive, NOAA scientists are there to greet them, and to take DNA samples. ...> Full Article |
 | Butterflies and moths are well known for their striking metamorphosis from crawling caterpillars to winged adults. In light of this radical change, not just in body form, but also in lifestyle, diet and dependence on particular sensory cues, it would seem unlikely that learned associations or memories formed at the larval or caterpillar stage could be accessible to the adult moth or butterfly. However, scientists at Georgetown University recently discovered that a moth can indeed remember what it learned as a caterpillar. Their findings are published in the March 5, 2008 edition of the journal PLoS ONE. ...> Full Article |
